In the natural cycle the creek takes on the water purification. Responsible for this work are the stones and rocks in the water which are the support for a clarifying biofilm consisting of micro organisms as well as the slope of the creek.
The biofilm has large reserves which can capture matter during overloading. This kind of situation can arise when a bath is emptied or during a family party. In these cases the plant must be able to cope quickly with a 100% increased loading which for WSB® clean is not a problem. The plant works equally well in the alternative situation of under loading. During long periods of non-use, such as absence due to vacation, the biofilm can die and as a result cause the plant to stop functioning. In this type of situation, the WSB® clean biofilm rests and immediately starts working again when the situation changes.
The effectiveness of WSB® clean is based on the special properties of the biofilm. It is the basis for the only waste water treatment plant that works reliably even below 12 °C with acknowledgement by the authorities.
Undertakes the decay of carbon compounds as well as the degradation of ammonia and ammonium, which impact greatly on the quality of water, to nitrate.
Via the denitrification mechanism, nitrate turns into nitrogen and oxygen, which escape into the atmosphere.
Sulphate is degraded here.
