FILTREX FMF FILTER


 

Filtrex Corporation represents the future of industrial fluid treatment. Our innovative backwashable filtration systems are both cost-effective and environmentally friendly.  The key to our system’s superior perfomance lies with the ingenious Filtrex candle system

The Filtrex Wafer and Candle

Our patented Filtrex wafer boasts a number of advantages over other filtration media. It has a high open area ratio, allowing high flow over a smaller surface area. Depending on the application, each wafer has up to 2 thousand microgrooves etched on each of its arched surfaces, allowing for precise filtration and maximum utilization of the wafer’s surface area.  Barring abnormal applications, the thermoplastic wafers are permenantly re-usable, which means no costly throw-away media like cartridges or paper, and no harm done to the environment.  They have the ability to self-clean in the backwashing cycle which minimizes system maintenance.

When stacked in perfect alignment over a hexagonal support core,the wafers form filter candles, which are capable of filtering particulate as small as 5 micron. For even finer filtering capability, a precoat of DE can be added to the filter candles making them suitable for even the most demanding conditions.

How it works

Depending on the application, the Filtrex candles are grouped into a vessel, which contain anywhere from a single candle to as many as several hundred. The vessels consist of an upper and lower chamber. During the Service cycle, the unfiltered fluid enters from the lower chamber, flowing across the candles where filtration will occur.  The water enters the candles through the microgrooves where the contaminants are intercepted, and then flows upwards through the cavities in the wafer candles.  The clean fluid is transported through these cavities into the upper chamber and out to the service connections. As the Service cycle continues, the contaminants will cake on to the candle surface. As the cake thickens, the differential pressure between the clean chamber and the dirty chamber will increase until it reaches a predetermined value, at which point the backwash cycle will be initiated.

Once backwashing is initiated, the clean chamber is pressurized using air, or other gas media, to ranges between 50-120 psi. The drain valve is opened, and the pressurized fluid flows in reverse at high velocity. This creates instantaneous compression of the candle spring, which separates the wafers and breaks up the contaminant cake, cleaning the filter in under a minute using a minimal amount of the clean fluid. Once clean, the Service cycle begins again.
