The module has five filter boxes layered one on top of the other. The wastewater enters into the uppermost filter box. Inside the module, the wastewater flows by gravity from one filter layer to the other through the openings in the end each box.  Finally the clean water exists the module and out to a gravel leach bed.  Multiple grey water filers can be connected together to increase capacity

Human waste, storm water or drainage water from foundations must not be fed into the filter. The cleaning capacity of the filter material in the module is good for about 3-6 months depending on volume, after which it needs to be replaced in accordance with the maintenance instructions.  The Biolan grey water filter tolerates a small amount of anti-bacterial and chlorine-based agents that are commonly used for cleaning.  However, toxic chemicals or substances that contain chemicals that can kill the micro-organisms that clean the wastewater, such as drain openers, paints, oils or solvents, must not be fed into the purifier.

Biolan Greywater Filter Basic is an insulated filter module for grey water. The filter is made of frost-resistant materials and is thermally insulated that can be used in winter months with the addition of a cable heater. The unit operates reliably and lasts a long time.  The filter can be used with a sump pump to pump the grey water up to the filter inlet if the grey water is coming from a lower point underneath the building or a basement.

A properly dimensioned, installed and operated Biolan Greywater Filter light wastewater system meets the limit values for total phosphorus, total nitrogen and organic material in grey wastewater in accordance with the Environmental Protection law (527/2014) and the Decree (157/2017).
