Filtra Sieve

Sieves are pre-filters which are used to remove coarse waste particles (such as leaves, algae particles, food residue, etc.) from pond water before it can enter the biological cycle. This reduces the work load for the bacteria in the biological filter.

It is best to connect the Filtra Sieves to either a skimmer and/or a bottom drain. The water enters the filter through two tubes with a 110-mm diameter. From here, the water flows over the stainless-steel sieve. The sieve contains holes which range in size from 300 microns to 200 microns (sufficient to allow water through yet prevent waste from getting through). The water comes into the inflow chamber, where the pump can pump it back into the pond or the biological filter. The water supply may be interrupted using a valve so that the sieve may be cleaned. The waste may be rinsed out of the system using a minimum amount of water. The outlet for the waste may also be connected to a sewer system.
