OneDrop - How it works

The project concentrates on conducting research, construction principles and design of comprehensive electrolysis unit that produces sodium ferrate from the steel anode and sodium hydroxide solution. Ferrate permits to carry on water treatment at the municipal water supplies or enterprise territory and the treatment of industrial wastewaters or drinking water.

The unit ensures that treated wastewaters discharged into the environment without any harm. Integrated electrolysis unit for the production of reagents for drinking water purification and wastewaters treatment does not have any domestic analogues and can ensure the competitiveness of the domestic water treatment processing systems compared to foreign-made analogues by price, productiveness and energy efficiency.
