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 effectiveness of WSB® clean is based on the particular properties of the biofilm. It enables the process to work reliably even at 4 degrees waste water temperature.
The interactions within the complex degradation processes result in optimal cleaning parameters. As a positive side effect, the biofilm also lowers germs such as coli bacteria by two to three orders of magnitude. Thus the purified water nearly has bath water quality.
