A range of filter elements and filtration degrees are available for the different filters.  This will allow optimum suitability for different solutions of filtration problems.  These solutions will take into consideration the type, concentration and particle size of particulate in accordance with the filtration method.

 

Screen elements are offered in a wide variety of configurations.  The configuration may depend upon the type of filter housing, application and the desired degree of filtration.  Molded plastic construction with either polyester or stainless steel screens on the larger filters are available. In general, screens are more efficient than discs when filtering sand. 

 

Disc elements are made up of numerous thin plastic discs that are stacked on a core.  As dirty water enters the filter and pressure increases on the outside of the filter element, the water pressure further compresses the rings.  Both sides of the discs are grooved so that the grooves cross each other when piled up and tightened together.  The water is filtered through the entire depth of each ring - not only on the outer surface.  The outer surface of the element will collect the larger particles and the inner grooved area collects the finer particles.  The disc element provides in-depth filtration with a high capacity to retain organic material.  The flow is from out-to-in. 

The disc element can be easily cleaned.  The core is opened allowing the discs to spin freely and be rinsed under running water.

Many factors should be taken when selecting the right filter:

• The required degree of filtration.
• Working flow rate:
      What is the maximum flow rate?
• Working Pressure:
      Minimum and maximum operating pressures.
• Water quality:
      For example, does it include sand, algae, silt, sticks, leaves or mussels?

In general, a larger filter area is required to treat dirtier water with a finer degeree of filtration.
