Modernizing the effluent treatment at a waste incineratorEight fully automatic filter presses for Chempark Leverkusen
Currenta recently has installed eight fully automatically operated Aquachem filter presses at the Chempark in Leverkusen, Germany. With this investment, the company has achieved a large efficiency improvement by reducing the labour costs dramatically and saving on filter aid materials.
Besides these savings, valuable space for other applications could be made available. Currenta is responsible for the waste incineration on this large industrial park. The flue gasses of the incineration plant are washed and the wash water is purified. This purification system consists of a settling system with lamella separators and a flocculants dosing system. The sludge from the lamella separator system is filtered in the eight filter presses in such a way that the solids can be disposed of.
Until now, Currenta used two huge filter presses with each 150 filter plates of 1200 mm size. The control and the cleaning of these old presses took a full time job of dirty labour. These presses
