Pond Sieves - Filtration

The Bio Sieve is a unique filter based on the combination of an EstroSieve and
moving bed filter. Besides an entirely new impermeable flap mechanism, the Bio Sieve 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 Bio Sieve 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.

The Pond Sieve is a simple to use and effective mechanical pre-filter for pressurised filtration systems and surface skimmers.

It is essential to use Pond Sieve in front of any type of pressurised bead filter to help prevent the necessity of excessive backwashing or clogging of these types of biological filters.

The Sieve is simply connected to either the bottom drain line or a skimmer line and is set 50mm above the water surface of the pond.
 
The Pond Sieve utilises a 300 micron screen and the flow is regulated by a new floating weir system 'Pondflow' (patent pending no. 102279) which overcomes the reliability and installation problems often associated with this type of product in the past.

• Greatly Reduced backwashing/maintenance of pressurised filters.
• Ideal for mechanical filtering skimmer lines.
• Very simple to install and reliable in operation.
• Unique 'Pondflow' regulation for constant flow
• Maximum flow rate 20,000 litres per hour.
• Tri-slot 300/500 micron wedge wire screen in 316 stainless steel
• Increased levels of oxygen
• 300/500 micron Screen Close-Up Side View of Screen/dirt particles

The Compact sieve can be used for primary mechanical waste removal,  such as a particle remover directly next to the pond or to a waterfall/stream return to the pond, or a mechanical particle waste pre-filter before surface mounted biological stages.
This unit can be connected to an existing pumped pond skimmer system. The unit must be mounted above pond water level.

This unit could be connected to a pond vacuum cleaner and the returned water from the vacuum cleaner can be fed into the input hose tail via a T-piece or directly.  For extra particle removal and saving your precious matured pond water.

This New Compact Sieve is ideal for the smaller ponds - great for ponds of up to 4,000 gallons.
