THE MONLAN STORY
Monlan began its industrial history in 1961 at a small converted warehouse in Lebanon, Indiana. Like all newly founded companies, Monlan struggled for a number of years to remain alive. However, by 1966 Monlan's products had become accepted by industry and it rapidly outgrew its home. In 1969, new manufacturing facilities were designed and built, tripling the floor space to 30,000 square feet. An additional 7-1/2 acres of adjoining land was also acquired for future expansion.
Monlan offers industry diversification with its new product development. Today, six units are manufactured: settling tanks, hydrocyclones, centrifuges, Mon-A-Matics, tubular filters, and liquid skimmers. This is Monlan's key to future growth. No matter what type of liquid filtration problem you have, Monlan can solve it and will apply the correct type of filtration equipment for each of your applications. Equipment is offered capable of filtering from 1 gpm to thousands of gallons per minute. In fact, no upper limit has been established on any of our filtration equipment. Filtration equipment has been supplied to almost every major corporation in the United States. Equipment has been shipped to such overseas countries as Russia, Yugoslavia, South Korea, West Germany, and the

MONLAN Liquid Clarification/Filtration Systems
Hydrocyclone Clarifiers
Settling Drag Tanks
DESCRIPTION
The centrifugal force of a hydrocyclone is generated by spinning the coolant within a cone. About 98% of solid particles above 10 microns, and up to half of the smaller particles, are forced out the bottom of the cone under a force of up to 7500 G. It is a continuous process, dumping sludge outside the system.
ADVANTAGES
Hydrocyclones are adaptable to a wide range of GPM or sludge volume requirements; for central systems or individual machines. The simplicity of the MONLAN model to fit into an existing coolant tank, and the continuous sludge removal at almost no operation costs are distinct advantages. Hydrocyclones can be effective precleaning components or complete systems.
LIMITATIONS
Space can be a limiting factor as tank capacity should be ten times the GPM requirements of the machines. Additional filtration is often necessary to prevent rancidity and frequent disposal of the coolant. Particles which float are not removed unless a surface skimmer is included.
Horizontal Mon-A-Matic Vacuum Filters
DESCRIPTION
The MONLAN Vacuum filters incorporate a large area of semi-permanent, positive barrier synthetic filter media through which the coolant is drawn by vacuum. Automatic cleaning of the filter media is accomplished by a positive displacement diaphragm action, discharging the accumulated sludge which falls to the tank bottom to be removed by the drag-out conveyor. Because of the air-activated cleaning principle, the required for pumping systems is much less. HORIZONTAL arrangement of filter elements provides for removal of the finest of materials and minimum height.
ADVANTAGES
These vacuum filters are in the low operating cost categories. The degree of filtration is variable by combinations of filter media chosen and types of sludge present in the coolant; they are capable of cleaning down to 5 to 10 microns. The prime advantage is the ability to handle high flow rates and high sludge capacities. They incorporate the only semi-permanent filter design that permits inspection or replacement of the media without shutdown of filter.
LIMITATIONS
Viscosity of the liquid being cleaned should be below 250 SSU. They are most applicable for oils. They are efficient for some, but not all, water-soluble solutions. When one hundred percent cleaning of particles of small micron range is desirable, centrifugal clarifiers can be incorporated to further clarify for some machines within the system.
HORIZONTAL arrangement of the elements does not provide easy methods for elimination of floating material. Floating material can be present because of air trapped in the sludge as well as being lighter than the coolant utilized.
Vertical Mon-A-Matic Vacuum Filters
DESCRIPTION
The vertical Mon-A-Matic vacuum filters incorporate the same filter principle and automatic cleaning action and utilize the same semi-permanent synthetic filter media as the horizontal. The only difference is in the mounting position within the system. This vertical arrangement has advantages in many applications.
ADVANTAGES
VERTICAL arrangement of the elements requires less floor space for large systems. The same low operating costs and no-downtime advantages are present as in the horizontal filters. The vertical position gives better unloading of floating particles, and the location permits the incorporating of a surface skimmer to carry out the floating materials. Periodic inspection of filter media is accomplished by vertical lifting of each element while the system remains in operation.
LIMITATIONS
A greater ceiling height is required, though less floor space than in the horizontal filters. Viscosity of liquid should be below 250 SSU and some but not all water-soluble can be handled. Other component clarifying methods may be incorporated, centrifugal or filter aids for finer filtration.
Engineering Recommendations and General Descriptions...
These general recommendations are intended only as a guide. Thorough study of all the variables within a system can lead to the best customized solution, incorporating the right components. An outline of the type of information needed is contained on page 27 of this brochure. With this data, MONLAN will promptly recommend and quote YOUR system.
Centrifugal Clarifiers
ADVANTAGES
The MONLAN Centrifugal Liquid clarifiers accomplish the removal of contaminants in suspension by spinning the liquid within a bowl and liner and thereby increasing the gravitational force 1200 times. This forces solids to the outside of the removable liner and allows the clean liquid to flow up over the top and into the clean reservoir.
DESCRIPTI0N
The centrifugal clarifier is efficient for fine particle removal, taking out all solids as low as 3 to 5 microns in size. It can be used with all types of liquid. It has a low initial cost and practically no operational costs. These cost factors and fine particle removal are its chief advantages. In the MONLAN centrifuge design, though not in competitive models, sludge removal is a simple matter requiring only minutes.
LIMITATIONS
The prime limitation for centrifugal clarifiers is the amount of sludge to be removed. Since the capacity of the bowl is 250 cu. in. (20 GPM model), the clarifier will remove sludge until this bowl is full and then must be cleaned. This limitation, where large amounts of sludge are created, can be overcome by using pre-cleaning systems before the dirty liquid reaches the centrifuge; for example, Settling Tanks, Drag Tanks, Hydrocyclones if water soluble, or Mon-a-Matic filters.
Tubular Filtration
DESCRIPTION
The tubular type filters incorporate a semi-permanent synthetic filter media sleeve stretched over a mesh tube. The liquid is forced through the media under pressure into the tube, and the clean liquid is retained. Cleaning of the media is accomplished by periodic backwash action which knocks sludge off the media and delivers it outside the system onto a drag tank.
ADVANTAGES
Tubular filters offer a fine degree of filtration because of the advantages of positive filtration and higher pressures compared to vacuum. Filter aids are introduced before filter action is reinstated, ensuring the desired immediate filtration degree. They operate with any liquid and vary from small particles to elaborate systems. They are normally considered as polishing filters because of micron clarity as fine or finer than the centrifuge.
LIMITATIONS
Tramp oil, such as hydraulic fluids from machines in a coolant system, can present a problem. Since it floats to the surface and shuts off oxygen, it promotes bacteria growth and helps cause rancid coolant. The belt liquid skimmer is a safe, sure way to remove these oils for reprocessing or disposal.
Heavy or bulky swarf must be removed by pre-filtering methods and not introduced into the tubular filter. Most tubular filter systems do not incorporate automatic backwash cleaning cycles because of the expense.
DESCRIPTI0N
Filter aíds are íntroduced into the dírty liquíd at the inlet or overflow weír. There are many varíetíes of these Filter Aid materíals earths, cloth and synthetíc fíbers etc. whích have the prímary purpose of rapidly coatíng the fílter media for fíner filtration. They are sometimes incorporated in eíther the Horizontal or Vertícal Mon-A-Matíc vacuum fílters for this purpose.
ADVANTAGES
As sludge buílds up on the fílter media, fíner and fíner fíltratíon results untíl the moment of automatíc cleaníng takes place. At thís moment, any particles smaller than the mesh of the medіa wí11 pass through. Fílter Aíds provide three advantages. 1 Positíve coatíng actíon. 2 Fíner micron removal. 3 Faster, almost ínstantaneous recovery of inedia for fínest fíltratíon.
LIMITATI0NS
The íncludíng of Fílter Aid materíals adds an operatíng cost as they are lost with the sludge and must be replaced ín onlythe proper type of fílter aid; materíal should be used that fíts specífícatíons of the filter media beíng used, líquíd beíng cleaned and other components of the system. They should not be added to a vacuum filtratíon system unless the system ís
desígned for their use.

CUSTOM MADE DRAG TANKS
Taílored To Suít the Condítíons Wíthín Each Applícatíon
SINGLE UNBAFFLED
The SINGLE UNBAFFLED TANK below is primarily for use on operations where the majority of sludge will settle out, and surface finish is not of prime concern. By removing the settled sludge from the bottom with the drag chain, the coolant will remain in a reasonable state. By adding either centrifugal clarifiers (see page 19-21), hydrocyclones (see page 10-13), Mon-A-Matic filtering systems (see page 14-17), or Tubular Filters (see page 22-23), the coolant can be kept in good condition for long periods of time.
DOUBLEUNBAFFLED
The DOUBLE UNBAFFLED TANK provídes a clean and dírty tank, both with drag scraper systems. As coolant returns from the machíne, it flows ínto the fírst tank and wíll be pumped up from the fírst section into the second sectíon. The drag in the second sectíon ensures that there wíll never be a need to empty either tank for cleaníng. This douЬle system ís very
applícable where large varíatíons in gallons per minute can be expected from the machínes as when several machínes míght cycle at one time. Additional clarífícation is sometímes desirable dependíng upon the applícatíon.

CUSTOM MADE DRAG TANKS CONTINUED
SINGLE SECTIONED
The SINGLE SECTIONED TANK contains a clean section without a drag. The settled and clean coolant flows up over the baffle and is delivered back to the machines. If greater clarification than the 40 microns that can be expected from this simple unit is desired, a centrifugal, hydrocyclone, Mon-A-Matic, or tubular filtration unit must be added. Usually, these units are designed for full capacity clarification, i.e., a 20 gallon per minute system requires a 20 clarifier. If the machines are not requiring coolant, the clean section will overflow back into the dirty section for continuous cleaning.
SINGLE SECTIONED TANK WITH EXTENSION
The SINGLE SECTIONED TANK WITH EXTENSION has been designed for dropping below floor level yet delivering the chips and sludge above the existing floor level. It is also applicable for extra drying time where the slow-moving chain will allow the coolant to drain off the sludge and back into the tank.

Approximately 98 of all solíds above 10 mícron in size are removed by the cyclonic princíple, and up to half of smaller solids. Recírculation of líquid within the system means that eventually most solids of all sìzes are removed. Hydrocyclones are on1y effectíve on water soluble liquids.
CONTINUOUS OPERATION
Hydrocyclone Claríficatíon systems are continuous and do not require shutting down the uníts for sludge disposal.
Sludge is delívered outside the system ínto a receptacle along with approximately two percent of the liquíd. This líquíd overflows back through the system. If no dirty líquíd is entering from the machíne, recirculatìon and
further clarification of líquíd in the tank takes place.

Centrifugal Clarífíers are compact self contaíned uníts that stand alongsíde the machíne tools they serve. As the dirty liquid flows from the machine toot under gravity it ís necessary to ensure that the ínlet heíght of the clarífíer allows at least 1 fall per foot.

ADVANTAGES OF CENTRIFUGE
. FLEXIBLE LINER
. EASILY REMOVED
. EASILY CLEANED
For clean and speedy disposal of the foreign matter extracted from the liquid, all Centrifugal Clarifiers are fitted with a long-life flexible liner. This is the quickest, simplest, and best-discovered method yet to be incorporated with centrifuging. Frequency of emptying the liner depends on stock removal of the machine tool. The procedure takes not more than minutes and can be shortened by the use of spare liners, allowing the full liner to be emptied at leisure. MONLAN liners are the result of much research and will withstand all known liquids over months of constant use. Spare liners are available off-the-shelf.
CENTRIFUGAL LIQUID CLARIFIERS

CLARIFICATION OF 3 TO 5 MICRONS POSSIBLE
So What Is New?
Improved Driving Method
The method of driving the spinning bowl which makes the other features possible as well as improves the already reliable unit. Previously, the bowl was set above a 1-1/2 hp, direct drive motor. Now the bowl is driven by a 3 hp, TEFC motor which is coupled to the bowl through a timing belt. The speed of the bowl is still the same, 3450 rpm.
Lower Inlet Height
Since the motor now sits alongside the spinning bowl rather than below, the inlet height has been lowered from the previous 22 inches to just 14 inches above the floor. This can be an advantage in many installations where gravity feed of the contaminated coolant from the machine back to the clarifier is desired. It also means the motor is more easily accessible and located best for heat dissipation.
Fast Stop Breaking
You will note a handle on the top of the clarifier which sticks out over the lid. This handle is a brake that must be pulled before the lid can be opened. It stops the rotation of the bowl in approximately 1-2 seconds. It is a friction-type brake, similar to those in an automobile. The incorporation of a brake has long been desired for two reasons. On the previous models, it required a waiting period before the bowl would stop spinning and the lid could be raised. This brake now answers all safety regulations as well as speeds up the operation of dumping the flexible liner.

MON-A-MATIC VACUUM FILTRATION SYSTEMS are capable of efficiently removing solid particles from the liquid. These masses, no longer suspended due to their accumulated weight, settle to the bottom of the filter tank. The Mon-a-Matic operates continuously without shutdown for cleaning or inspection. Solids are drawn to the filter media by vacuum or settle to the bottom and are drawn out of the system by the drag flights.
Periodic backwash of the filter media elements is accomplished by a ram-action diaphragm. As fines collect on the filter media, they form a functional part of the filtering process. As buildup increases, filtering efficiency increases but the flow through the media decreases.
A pre-determined cleaning cycle backwashes the settling time for heavy solids, and drain off of the filter media by reversing the flow through each filter element. This ram diaphragm action knocks the agglomerates from the collected solids. A clean reservoir contains coolant that has passed through the filtering media.
Provide Continuous Efficient Filtration
Inspection or Servicing Without Interruption or Draining
Horizontal element arrangement can accommodate several filter element assemblies, determined by the flow requirements, viscosity of the liquid, and amount of contamination. Each element can be easily disconnected and swung up for inspection or service of the media without shutting down the rest of the system.
When even more filter elements are required for heavy flow rates or space is limited, the Mon-a-Matic vertical arrangement outlined on the following pages offers even more flexibility in design.

All the features of the horizontal vacuum filter arrangement ensure efficient filtration of solids, which are drawn to the filter media by vacuum or settle out of the system and are removed by the drag flights. Periodic automatic backwash of the filter media is accomplished by a ram-action diaphragm. Alternate cleaning of elements can be scheduled so that continuous filtration is maintained. Inspection or replacement of individual filter element media can be carried out while the system remains in operation. As swarf builds up on the media, filtration becomes finer until automatic backwash action is triggered.
In the vertical arrangement of filter elements, the incorporation of skimmer flights allows continuous removal of floating particles. Inspection and replacement of the media are even easier compared to the horizontal arrangement. When space limitations and filtering capacity conflict, the vertical arrangement permits higher flow rates and greater capability for heavy chip removal with less floor space. The vertical Mon-a-Matic is an engineering masterpiece, especially suitable for large central systems.
Two filter elements without the media are shown in the vertical arrangement at the end of the reservoir tank. Skimmer flights are clearly visible overhead. No draining of the tank is required for inspection or service. Disconnecting a filter element is straightforward by shutting off the filter vacuum, inspecting or replacing the pleated filter media unit, and reassembling it into position.
The preceding points culminate in the most important benefit: lower total operating costs because Monlan eliminates the need for expensive disposable media, avoids draining the tank for media inspection, and allows media changes on larger systems without shutting down the system.
Summary:
The Mon-A-Matic vacuum filtration systems, whether horizontal or vertical, offer efficient filtration of solids with continuous operation and easy maintenance, making them ideal for various industrial applications.MONLAN TUBULAR PRESSURE FILTERS
MONLAN Offers You
These lmportant Benefits
MONLAN Tubular Pressure Filter System:
Operation:
The MONLAN Tubular Pressure Filter System operates as a fully automatic filtration system designed for both new installations and retrofitting into existing coolant or dielectric reservoirs. It effectively removes contaminants from fluids without interrupting production, ensuring continuous operation and high clarity of the reclaimed coolant or dielectric.
System Components and Operation:
Dirty Coolant Entry (Section No. 1):
Dirty coolant enters the system either by gravity or pump into the dirty inlet section.
From here, it moves towards the rear of the filter under a vertical baffle to the recycle section (No. 3).
Recycle Section (Section No. 3):
Filter pump No. 2 draws suction from the recycle section No. 3 and delivers the dirty coolant to Tubular Filter No. 4.
Simultaneously, precoat feeder No. 9 introduces a measured amount of dry precoat into recycle section No. 3. This precoat mixes with the dirty coolant and deposits on the exterior of the filter tubes in Tubular Filter No. 4, forming a filter cake.
Filtration (Tubular Filter No. 4):
Coolant passes through the filter tubes in Tubular Filter No. 4, where filtration occurs.
The filtered coolant is automatically directed through recycle valve No. 5 back to recycle section No. 3 to complete a loop, maintaining continuous operation under automatic control via remote panel No. 10.
Clean Coolant Separation (Section No. 7):
Upon completion of the recycle timer, automatic filtrate valve No. 6 opens while automatic recycle valve No. 5 closes.
Clean coolant is directed to clean tank No. 7, which fills and spills over a dividing baffle back to recycle section No. 3 for further processing.
Distribution (Clean Pumps No. 8):
Clean pumps No. 8 draw coolant from clean tank No. 7 and distribute it via a suitable manifold to the work area where it is used.
Dirty coolant from the work area is returned to the dirty inlet section No. 1 to begin the filtration cycle again.
Blowdown and Maintenance:
The filter system automatically initiates blowdown when a pressure differential is sensed by an automatic pressure switch on Tubular Filter No. 4 or by a time override set in remote control panel No. 10.
During blowdown, filter pump No. 2 shuts down, automatic valves adjust accordingly, allowing spent diatomaceous earth and sludge to pass to the blowdown dirty inlet section No. 1.
A conveyorized tank No. 13 collects the sludge and automatically conveys it up a ramp to a discharge point for removal.
Automatic Recycle:
After blowdown, the filter system automatically resumes operation, beginning with the functions described above.
Precoat feeding occurs only after blowdown, ensuring efficient use of precoat material.
System Advantages:
Continuous Operation: Operates automatically without the need for frequent manual intervention, reducing downtime.
High Filtration Efficiency: Provides low micron clarity suitable for clean liquids, enhancing fluid quality.
Space Efficient Design: Suitable for installations where space is limited, offering flexibility in placement.
Low Maintenance: Designed for minimal daily maintenance, reducing operational costs and effort.
The MONLAN Tubular Pressure Filter System is a robust solution for maintaining fluid cleanliness in industrial applications, offering reliability, efficiency, and ease of operation.
