Its design flow rate is a whopping 1500 L of washing water per day and it also tolerates occasional overloading well. The treatment is biological and the water flows through the treatment plant by gravity. No need for a filtration field, no chemicals, no peat, etc. replacement. Easy and hassle-free treatment of grey water in a completely corrosion-free treatment plant. Suitable for: for detached houses for leisure homes for continuous and periodic use course and camp centers also well suited for coastal areas and areas with stricter cleaning requirements can be installed on all plots and soil IISI H12 is an excellent choice together with the IISI closed tank for sites where separate drainage is being built.
