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.

Lappeenranta wastewater plant

Ladan, Majed and Hamid visited the Lappeenranta wastewater plant on 29th June. Lappeenranta wastewater is treated mechanically, chemically, and biologically at four treatment plants. There are several processes in water treatment such as screening, sand sedimentation, coagulation (add ferrous sulfate), primary clarification,…

Water sampling from the Seleznevka river/Rakkolanjoki

The Seleznevka river is a common water body between Russia and Finland. In Finland, the river is called Rakkolanjoki (fin. Rakkolanjoki). In Russia, the Seleznevka flows through the territory of the Vyborgsky district of the Leningrad region, in Finland – through the territory of Lappeenranta. Length is 53 km (across…

Europe’s best wastewater treatment plant

In the 2020s, wastewater in the Lappeenranta region will be pumped through new pipelines to a state of the art treatment plant to be constructed in Hyväristönmäki. The water treatment requirements will be Finland’s strictest, on account of the extreme sensitivity of the receiving waters. According to the preliminary plans, the…
