Drinking Water Preparation System for Natural Freshwater - Akvalid VU Application

The unit is designed for disinfection, decolourisation, filtration of fresh water up to drinking water level. It consists of a pre-filtration unit with simultaneous supply of sodium hypochlorite, prepared on site in the electrolysis unit, for disinfection and decolouration, filtration unit on wire filtering elements LLC "Akvalid", which are compressed by the direct and uncompressed by the reverse flow of water. A layer of domestic sorbent is washed onto the elements for filtration fineness up to 1 micron and reduction of water hardness and salt content.

The layer is changed automatically. Sorbent is fed into the filtration unit in a constant mode to prevent sticking of the filtering layer. After filtration, sodium hypochlorite is added to the system to ensure the required residual chlorine content according to the norms of SanPiN1.2.3685-21.

The advantages of the technology are the absence of imported membranes, coconut coal; no need for coagulation, flocculation, sedimentation of impurities.
