Operating principle
Water flows through the purification tank where the filtering layer detains all mechanical impurities larger than 30 microns. Filtered impurity particles are collected in purification tank and subsequently washed into drains.
Activated charcoal is used in purification process to remove chlorine, odors and to improve palatability as well as quartz sand layer consisting of grains of different fractions (0,2mm - 5,0mm).
