Abstract
A filter system and filter suitable for water treatment includes a filter having a housing with a water inlet and an outlet, the housing defining a filtration chamber therein. The filtration chamber has filter media therein having a plurality of at least partially porous filtration beads and a pump for pumping water to the inlet. Such a filtration system enables high nutrient removal thus minimising the food source for algae.

- a pressure biofilter comprising a housing having a water inlet and an outlet, the housing having chamber walls defining a first filtration chamber therein, the first filtration chamber having filter media therein comprising a plurality of at least partially porous ceramic filtration beads having exposed ceramic interior surfaces;
- and
- a pump for pumping water to the inlet;
- wherein
- the ceramic beads have a dry average material density of 0.1 to 1.2 kg/litre;
- the ceramic beads are substantially spherical;
- the ceramic beads are unconstrained within the filtration chamber;
- and
- the ceramic beads are hydrophilic.
