Sludge Treatment Solution
Sludge mechanical dewatering method
Sludge mechanical dehydration is the use of pressure filtration, vacuum filtration or centrifuge to dehydrate digested sludge or sludge from sedimentation tanks (mainly capillary bound water), which is not limited by land area and climatic conditions, and does not smell like a drying field. Pollution or harm by flies, so it is a better sludge dehydration method, but the equipment and funds are higher.
Centrifuge dehydration is similar to thickening centrifuge dehydration, but the speed is higher, and the moisture content of the obtained sludge cake is between 65% and 85%. The discharge water from the dehydration equipment is generally pumped to the inlet of the sewage treatment plant for further treatment.
sludge drying method
The sludge drying method is to further reduce the moisture content of the dehydrated sludge from 65% to 10-30% (mainly remove absorbed water), and turn it into sludge powder, which can be packaged as fertilizer and shipped out. Commonly used drying methods include air drying and drying.
Sludge air-drying method: The mud cake with a moisture content of 65-75% is piled up in the canopy and evaporated by the wind, and the moisture content can be reduced to 20-30%. It is often used in areas with dry climate and little rain.
Sludge drying method: There are rotary kiln sludge furnace system or rapid drying system, which is actually a combined drying-incineration system. Pathogens in sludge can be killed by heat.
