Biological elements are particularly suitable for biological water purification within aquaculture and traditional wastewater. Moreover, biological elements can be used with great advantage to ochre filtration in e.g. water works and in recirculation systems hatchery and land based farm.

     The patented asymmetrical design distinguishes itself by ensuring an optimum flow through the filter. Biological elements provides a good flow with a large surface area of 750m2/m3, the filters work with very high turnover rates. This makes it possible to achieve environmental gains in the form of a reduced energy and water consumption.
