Municipal Wastewater

The vision of municipal wastewater treatment has changed significantly over recent years. Next to the tighter consent levels, reduction of CO2 emission and energy consumption have become increasingly important. The idea that energy can be extracted from municipal wastewater and waste products can be recovered and upgraded to raw material has stimulated the development of new technology.

With the use of fine screens as pre-treatment, CirTec contributes to the objectives of the Waterboards. Finescreens relieve the biology and thereby contribute to the energy objectives. The sieved material that is secreted mainly consists of cellulose which has enormous potential as a raw material. Finescreen technology for municipal wastewater treatment is far beyond the pilot phase. Approximately 400 of the 700 Salsnes finescreens worldwide in operation, treat municipal wastewater.

Fine screens are not only used for treatment of raw influent, they are also applied for screening filtrate from centrifuges. The use of Salsnes finescreens behind overflows in combined sewer systems have proven to be a promising solution. A study CirTec has recently carried out in close cooperation with a number of Waterboards and consulting companies has demonstrated that.
