Waste water sludge dewatering can save a company money by reducing the volume of waste being transferred to disposal plants and landfills. It is a process that reduces the amount of liquid in the waste through a procedure known as dewatering.
Dewatering is literally the removal of water from solids or the separation of liquids and solids. Many businesses and residential areas have septic tanks, which often need to be emptied or drained. Companies that drain these tanks dispose of the sewage or sludge as part of the workload. But before disposal, the sludge needs to be dewatered and Biosolids removed.
The Process Explained
Waste water sludge dewatering is simply removing the excess waste water from the sludge or sewage. This is done to reduce disposal costs as removing water can significantly lessen the weight and volume of the sludge. Once the sludge is dewatered, it is then removed and disposed of in local landfills.
Leftovers from Sludge Dewatering
Biosolids are the solid compounds that are left over as a result of a dewatering and treatment process. These solids are new sewage or sludge. Instead, they are solid materials generally composed of water and organic materials such as nitrogen, phosphorous, potassium and sulfur, copper, zinc, calcium, magnesium, iron, boron, molybdenum and manganese.
Once separated, they are then dewatered and filtered in order to be reused as fertilizers and other products. Some Biosolids are even used in land rehabilitation, forestry and agricultural products.
How to Dewater Waste Water Sludge
Dewatering sludge wastewater is generally done by a hired company that can send out equipment to collect the sewage and dewater it. Some waste water sludge dewatering processing can be done through mobile units, while other dewatering processes involve collecting the sewage and then transferring it to a dewatering station.
Cost-wise, it is generally a good idea to locate dewatering companies that provide all dewatering services in one location. Some companies not only operate the trucks and machinery to empty the septic, but they also operate company owned dewatering systems. This provides a one stop shop for consumers as well as creates an in-house dewatering service than can save the dewatering companies time and additional disposal fees.
