This mega-sized sieve incorporates a 495mm wide stainless-steel screen making it one of the largest on the market with extra capacity to cope with high flows and the ability to add a second inlet.
It is the ideal replacement for gravity fed vortex and brush chambers acting as an efficient pre-filter for BubbleBeads or other biological filters, and helps to aerate water in the process. It can even act as a biological filter with the addition of buoyant biomedia.
The BioSieve is a unique filter based on the combination of an EstroSieve and
moving bed filter. Besides an entirely new impermeable flap mechanism, the BioSieve is constructed solely from one piece, meaning no seams or adhesives holding it together. As a result this may easily be buried without worry of damage.
The BioSieve is a gravity fed system with a 110mm entrance for the water to allow for a maximum flow rate. A screen element is also included in the system to allow for any dirt or organic particles to be easily stopped and removed from your water system.
