Restoration of fresh water circulation and the biological purification of the water


Under the umbrella of an Environmental Cooperation Program between China and Italy, this urban regeneration project is addressing the problem of water eutrophication and pollution in the Shichahai Lake system in Beijing.

The historic Shichahai Lakes required the restoration of fresh water circulation and the biological purification of the water. The project started with a detailed feasibility study and the selection of the most efficient solutions followed by the actual restoration of fresh water circulation in the lake, and the biological purification of the water.

For this purpose Euro Mec developed a water treatment plant (WTP) specifically designed to trial different purification options. The WTP included the following stages: water intake pumps, coagulation‐flocculation, chlorine metering, sand filtration, dechlorination, cartridge filtration, reverse osmosis treatment and air injection.
For months data was collected from both the system and the waters to determine exactly what treatment, or combination thereof, was most effective.

The successful pilot project determined the optimum combination of filtration, reverse osmosis treatment and water circulation required to restore the water quality both for the ecosystems relying on the water and the people enjoying leisure activities on and around the Shichahai lakes in Beijing’s Forbidden City.
