Reduced Maintenance - 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

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.

Backwash

At 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).

Maintenance

Should individual filter elements require maintenance or eventual cloth replacement, they can be easily removed from the flowstream without the need to discontinue influent flow to the whole filter or divert the waste stream. Flow simply needs to be discontinued to the individual element while all other filter elements remain on-line, providing continued wastewater filtration while maintenance is performed.

Fixed Plate Cloth Media Filter - Reduced Redundancy  

This simplified manitenance process provides a convienient and non-intrusive means of providing periodic maintenance without causing undo stress to the operators, mechanism, or upstream processes.
