Land based aquaculture needs constant monitoring and filtering of the tank water. Curved wedge wire screens filter out feces and other contaminants that might unbalance the water composition. It is a preferred filter medium because of its low cost and ease of installation.

Slot tubes

Slot tubes are being used to filter water for culturing live fish feed like artemia or krill or to prevent loss of bio-media (bacteria) that is needed to purify the contaminated flow.

Both flow directions (Flow Out To In and In To Out) are possible.

To filter all organic content out of a tank, a self-cleaning system equipped with wedge wire cylinders can be used. The construction is axial internal wire, the normal flow is from in to out (FITO) and the cleaning is carried out by a spray system from the outside.

Degasser screens

As the tank water is constantly being circulated, there is a build-up of CO2. Trislot ®wedge wire screens can be used to release the CO2 from the water and add new oxygen. The water needs to flow at the right amount of time over the screen to allow the release CO2. This can be obtained by adapting the open area.
