Wastewater treatment

One of our core business areas is to design and build wastewater treatment plants.
In addition to conventional purification methods we also offer special solutions, e.g., for processes with variable loads and low temperatures.

Close cooperation between the client and Econet at an early stage of the project ensures a high-quality end result that fully meets the client’s needs.

We also aim to constantly develop our operating methods and cooperation models in order to offer our clients the best possible service in the future.

In the most comprehensive cases the service range of Econet Group may cover the entire life cycle of a wastewater treatment plant investment beginning from design and build phase up to the commissioning and maintenance of the plant.

Municipal wastewater treatment plants

We implement construction, expansion and renovation projects of municipal wastewater treatment plants, either as a main contractor with overall delivery, or on the basis of partial contracts, e.g., by supplying machinery and equipment with piping. The projects may be pre-designed by the client, or we design and build them on turnkey basis. Our wastewater treatment plant projects vary in size from small community plants to some of Finland’s largest municipal wastewater treatment plants.

We have built new wastewater treatment plants or carried out renovation work in many major cities in South and South-West Finland, e.g., in Helsinki, Tampere and Turku.

Industrial Wastewater Treatment

We have designed and implemented industrial wastewater treatment projects in numerous pulp and paper mills in Finland and abroad, including Metsä-Botnia Joutseno Pulp Mill, Stora Enso Anjala and Veitsiluoto Paper Mills and UPM Kaipola Paper Mill in Finland, Hyltebruk Paper Mill in Sweden, Estonian Cell Pulp Mill in Estonia, UPM Shangshu Paper Mill  in China, Mondi Kraft Paper Mill in South Africa, Orion Pulp Mill in Uruguay, and Veracel Pulp Mill in Brazil.

Leachate Water Treatment

Leachate water is waste-polluted and harmful water which is difficult to handle, because it has been in contact with waste of landfills and waste processing areas. We implement different kinds of treatment solutions for harmful leachate water. The most important of these projects has been the leachate water recycling system at Ämmässuo waste treatment plant in Espoo. For the Helsinki Region Environmental Services Authority HSY we have implemented a process contract for recycled water plant and a turn-key contract for water regulation and recycling system on a decommissioned landfill.
