High-effect Electro-osmotic Dewatering Technology in Sewage Sludge

Through independent research and development, the Company successfully develops a treatment device of sewage sludge, which is introducing a High-effect Electro-osmotic Dewatering Technology and based on the use of mechanical pressure in conjunction with electroendosmosis. Solid-liquid separation after this treatment could significantly realize with results of water content of 80%-95% reduced between 60%-35%(adjustable), an apparent breakthrough compared with conventional mechanical dewatering methods of either diaphragm or plate-and-frame type filter press.

The technology and process could produce a dewatered sludge cake in a relatively high heating value by ultimately retaining the organic matter. This allows for easier combustion of the sludge and even self-sustaining sludge incineration. It is a technology for stabilizing and reducing sewage sludge in harmless and recycling way, providing a great technical support for solving environmental problems in municipal sewage treatment industry.

Self-sustained combustion of sludge
