Sludge Dewatering Equipment
Sludge Dewatering is the process of removing water from liquid sludge, and is a key element for water and wastewater management. Over the years there has been tremendous advancements in sludge dewatering equipment which have helped reduce the cost of managing wastewater.
Sludge Dewatering Equipment is essential for any wastewater treatment facility and numerous efficient technologies exist on the market today including belt filter presses, centrifuges, and screw presses. Each of these solutions represent a fully mechanized approach to sludge dewatering. Soil-washing systems are also becoming popular as they are less intrusive and luxurious way to dewater sludge.
Belt filter press are the most widely used sludge dewatering solutions and works on the simple principle of creatinng a pressurized uniform bed or cake of sludge indicating a complete dehydration of the material. Belt filter presses are used to dewater a wide range of Sludge including activated sludge, municipal waste water, digester sludge, and industrial sludge.
Centrifuges are also becoming popular as a sludge dewatering solution due to their high performance capabilities. The principal behind this type of dewatering process is to separate solids from liquid by creating an ultra-centrifugal force. Centrifuges are primarily used in large industrial industries and within municipal operations to reduce the need for handling large volumes of sludge.
Screw presses are one of the major types of dewatering units available today. These machines utilizes inclined screw shafts which operate in concert with a perforated sieve to effectively separate the water from the solids of the sludge.
Soil-washing systems are also becoming popular as they are less invasive and luxurious way to dewater sludge. Traditional soil-washing process uses overland conveyors, crushers to reduce the size of the sludge, and specially designed vacuum filters to extract the water content from the sludge.
Overall, Sludge dewatering is an important process for treating wastewater and there are numerous efficient technologies available in the market today. These technologies range from belt filter presses, centrifuges, and screw pressesto less invasive and luxurious soil-washing systems. Advances in sludge dewatering technologies have helped make wastewater treatment more cost-effective and environmentally sound.
