Fixed Plate Cloth Media Filters & Weirboxes - No Moving Parts

No Moving Parts - Simple Operation

MFC Fixed Plate Cloth Media Filters are designed to provide tertiary wastewater treatment following municipal and industrial activated sludge, extended aeration, SBR and other advanced secondary treatment processes. The filter operates entirely by gravity, requiring only small head differential, making it ideally suited for municipal treatment facilities located in low lying areas or industrial facilities which cannot accomodate large piping or hydraulic changes.

MFC cloth media filters feature an innovative cloth media membrane of 100% acrylic material which removes even very fine suspended solids and TSS carry-over from secondary treatment processes. This fabric membrane is attached to multiple vertically placed media panels, each with its own internal framework, capable of handling significant fluid flow. Vertical media placement limits the filters mechanical footprint while allowing heavier or larger solids to fall to the bottom of the filter and not onto the media.

MFC cloth media filters feature a unique 'fixed' or static panel design, which limits mechanical wear and maintenance. Problematic backwash manifolds or spray bars and associated pumps are eliminated by using differential head generated by incoming flow to the other filter 'cells'. Each filter contains multiple filter segments, each of which is backwashed in sequence during the backwash stage, all while influent continues to enter the filter at all times.

Filtering Mode - During normal operation, influent is evenly distributed along the length of the common influent channel, then enters the individual media element channels where heavy solids settle to the bottom of the influent channel or are removed by the vertical cloth media elements. Filtered water is collected in the common filter bay and exits over the control weir.		Automatic Backwash - When the water level in the influent chamber reaches a preset level (or on time), each filter element is backwashed in sequence by closing it's influent valve and opening it's backwash valve. Water continues to enter the other filter cells, providing filtered water to the common filter bay. Dirty backwash flows in reverse to the influent/backwash channel and out by gravity. All media panels are cleaned in sequence while flow continues to enter the filter at all times.

Since filtration and backwash are produced by gravity, no pumps or vacuums, spray bars, or rotating elements are needed. This significantly reduces mechanical complexity and element wear, reducing installed cost and maintenance requirements.

All filtration and backwash operations, including the air scour to enhance cleaning efficiency, are powered by a small PLC panel and compressed air (using a small local compressor or centralized air if available).

Reduced Redundancy & Maintenance

MFC's Fixed Plate Packaged cloth media filter systems utilize multiple isolated media panels within each tank to provide filtration & backwash of wastewater. This plurality of filter elements allows incoming water to continue to enter the filter system while individual filter elements are being backwashed or are removed from the system.

If periodic inspection of the cloth media is required, individual media elements can be isolated from the remaining elements and removed from the filter system for periodic inspection and media replacement.

ALL internal components of MFC's cloth media elements are modularized and integral to the removable media element (and NOT attached to the tank). Therefore, ALL internal components for each element are removed from the tank while flow continues to the other online filter elements.

This feature, in combination with an appropriate tank or basin design, allows elements to be removed, inspected and returned to service without decreasing system capacity or interrupting flow. ALL media within the system can be changed sequentially, while the remaining installed online elements treat the full design flow.

Fixed Plate Package Filters in 100% Stainless Steel

Fully packaged cloth media filters are offered in 100% stainless steel and contain 100% non-corrosive internal components to limit maintenance requirements and increase equipment life. Influent and backwash valves are mounted at the factory and preprogrammed for optimal operation. A simple PLC based control system and small 2-5 HP compressor system is included to provide fully automatic operation.

MFC's Packaged cloth media filter systems come in a wide range of sizes to accomodate a variety of municipal, residential, & industrial applications with flow ranges from 10gpm up to 6.0MGD in a single filter. Elements range in size from 6sf of media per element up to 48sf of media per element, with systems available from 2x elements up to 8x elements in a single tank.

Larger flows can be accomodated using multiple packaged filters in parallel or by using Modular Equipment for Concrete Basins

All MFC equiptment is PROUDLY
designed, fabricated, and
assembled in the U.S.A.
