QUACULTURE FRANCE offers a complete range of sand filters specifically designed and adapted for aquaculture, fish farming, shellfish farming, aquariums, and ponds.
Our sand filters contain no metal parts, making them perfectly suited for treating corrosive water such as seawater.
Sand filtration is highly effective in achieving clear and transparent water. We guarantee a filtration fineness of 40 microns at the outlet of our sand filters.
We offer both molded and wound sand filters. The sizing of the filters is based on the amount of suspended solids (TSS – Total Suspended Solids).
All options are available:
-
Operating pressure from 2.5 to 8 bar
-
All filter diameters up to 3 meters
-
Vertical filters for fine filtration and horizontal filters for high flow rates
-
Sand bed height from 0.4 to 1.2 meters
-
Underdrain plate (KOK model)
-
Standard or reinforced nozzle arms, depending on the application
-
1.5″, 2″, 3″, and 4″ connections via multiport valve
-
90 to 250 mm connections via valve manifolds
-
Optional automatic backwashing
-
Differential pressure sensor to monitor filter clogging
-
Wash water recovery solutions available
