Key questions

  • What improvements are required to overcome the water crisis?
  • Freshwater: limited resource?
  • How well is the humanity familiar with current water pollution situation
    in the world?
  • What are the benefits associated with a new water treatment approach?


  • Guarantee the right to water;
  • Decentralize the responsibility for water;
  • Develop know-how at the local level;
  • Increase and improve financing;
  • Evaluate and monitor water resources.

Project objectives

  • Extensive research on novel water purification approach;
  • Design a pilot plant of the purification system;
  • Development of the pilot plant;
  • Test the plant with couple of biggest end users in the region;
  • Design and development of mobile plant.

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.

Sodium ferrate (VI) – a “green” reagent for safe water. Daria Navolotskaya’s school student achievements

At the beginning of 2020, Dr. Daria Navolotskaya from Saint-Petersburg State University supervised the scientific work of a school student – Vera Shallieva. The work was devoted to the treatment of industrial wastewaters by ferrate (VI). As a result of her work, Vera showed that treatment by electrochemically generated ferrate…

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 sulphate), primary clarification,…

Wastewaters will be analyzed for coronavirus

According to the article from 22nd of April 2020 published on The Finnish Institute for Health and Welfare (THL) website, THL has started to collect water samples from Finnish wastewaters to determine the presence of COVID-19. This project is a cooperation between The Finnish Institute for Health and Welfare and the University of…
