bioforce pond purifiers

Bioforce is a closed, pressure system holding more bacteria than a similar size normal filter. It is small enough to be completely hidden near the pond when it is buried up to its lid.

Being pressurised by the pond pump, water can be pumped up from the Bioforce to the top if a waterfall. This makes it even easier to hide.

Bioforce is ideal for pond keepers who want simplicity, clear water and an attractive hidden water system.

Bioforce is available as a biological filter or combined biological filter and UVC. With the UVC, clear water is guaranteed if the correct size of Bioforce is used.

How to install a Bioforce

Bury the Bioforce up to its lid next to the pond.

It is best to use a Titan solids handling pump which moves solids from the pond to the Bioforce where they can be easily flushed away. Pond water pumped up to the Bioforce.

Water from the Bioforce can either be passed straight back into the pond or up to the top of a waterfall. A waterfall will increase aeration.

Simple de-sludge system.

Bioforce filters can be cleared of sludge without the need for manual cleaning. Just swap round the hoses and turn on the pump for a few seconds. Sludge will be cleared from the bottom of the Bioforce and easily disposed of (excludes the Bioforce 1100, 1100uvc, 9000 and 9000uvc.)

Bioforce 2200/4500 UVC

This is the system used in the Bioforce 2200 UVC and 4500 UVC. In the Bioforce 1100 a different is used as this is more effective for smaller ponds.

1. Water enters tangentially, spinning the water inside the Bioforce to settle out the solids.
2. Water is forced through special density foam. Because the water is pressurised the foam can fill with many more beneficial bacteria without becoming blocked. It is this larger number of bacteria, taking pollutants out of the water, that make Bioforce so effective.
3. Water then passes close to the UV light, separated from it by a quartz glass sleeve. UV light makes algae clump together and sink to the bottom of the pond or get trapped in the Bioforce foam next time round.

• Beware of UVC's that use ordinary glass or plastic sleeves around the UVC light. Glass and plastics are barriers to UV light cutting out up to 90% of the UV rays.

1. Pond water passes into Bioforce 9000 creating a vortex in the top.
2. The water is forced through three specially graded foams which catch particles and hold beneficial bacteria all the way through. This increases the performance of the unit and increases the time between cleaning.
3. Almost solids free, the water passes through plastic biomedia where more beneficial bacteria cleanse the pollutants.
4. Water then passes close to the UV light, separated from it by a quartz glass sleeve. UV light makes algae clump together and sink to the bottom of the pond or get trapped its the Bioforce foam next time round.
5. When the Bioforce becomes blocked this red button its rise up. Water will then bypass the biological foams but still pass the UV lamp. This signals that the foams need rinsing in pond water.
