There was showed a possibility of membrane cell creation that is operated on principle of electric chemical generator. With the aid of membrane cell was attained decreasing of suspended matters concentration mw means of precipitation in catholyte and anolyte with regard to test experiment on precipitation of suspended matters into influent eater. There was specified a possibility of reagentless wastewater treatment from heavy metals by means of water filtration in membrane cell and from organic resistant to oxidation substances (benzene, methylene blue). There was showed that energy density, generated by membrane cell, substantially increased with increase of solution mineralizing.
