Filter material determines filtration effectiveness
The filter material rather than the filter itself determines filtration effectiveness. Mechanical filter material keeps out the dirt but does not cause waste matter to disintegrate. Biological filter material breaks down waste matter but cannot keep out the dirt. A combination of the two therefore often provides the best solution. 5,000 ml pack.
The hexagonal tunnel structure of the Nitraat Filter material ensures a sufficient number or oxygen rich zones. But also oxygen poor areas, where bacteria (both aerobic and anaerobic) can develop. Nitraat Filter material can be used efficiently, long term in both pressure filters and biological filters.
The principle behind biological filters is, through the use of micro-organisms, create a better and faster exchange of organic elements. The wadded material and the carbon together guarantee an excellent water filtering.
