Cloth Media Tertiary Filter

The units’ deliver highly effective filtration and have a wide capacity range. Fluidyne filters remove suspended solids down to 10 microns and can be configured for flows ranging up to 250 litres/s per unit. Units are offered in completely assembled 100% SS free-standing packages, or as modules for retro-fit into new or existing concrete basins.

Their innovative fixed panel design uses simple open-close valves and gravity to produce filtration and backwash flow. Having no internal or submerged moving parts eases installation, reduces maintenance, and simplifies overall operation.



Each independent media plate is made up of two rectangular cloth panels which face each other within a stationary framework. Influent enters the filter, then is directed to the bottomside of each plate. Suspended solids collect on the interior surfaces of the cloth plates or settle to the bottom of the channel, with clean, treated water collecting in the filter’s main tankage area.



As solids accumulate on the cloth surface, water level in the influent channel begins to rise, eventually initiating a backwash operation. Each independent cloth plate is cleaned in sequence by allowing gravity to force flow in reverse. Backwash flow is produced entirely by gravity, by simply opening each plates associated backwash valve. Air is injected within the interior of the plate during backwash to enhance cleaning.
