Experimental Studies of the Electrochemical Method of Water Purification in the Subarctic Territories

Outcomes of experimental, analytical, statistical research on aquatic mediums in various conditions of the Maata river’s diffuse sources, village Berdigestyakh (Yakutia), by using the electrochemical coagulation method, substantiation of optimal parametrization of water purification have been presented. The study’s results of using a non-routine electrochemical conditioning method to produce the high-quality drinking water without chemicals from the surface water of the river Maata to comply with the drinking water treatment requirements have been elaborated. The test approval of soluble electrodes has been carried out with the St3 steel to assess their efficiency while applying the electrochemical treatment of low-mineralized high and duckweed covered northern water systems. The modes for water electrochemical conditioning have been identified and substantiated, structural elements and parameters of the core assembly unit have been developed for implementing the electrocoagulation method under the village Berdigestyakh conditions, as well as schematic diagrams of their arrangement into separate modules of various capacities.
