The process of removing contaminants from municipal wastewater, containing mainly household sewage plus some industrial wastewater is known as sewage treatment. For removing the contaminants, physical, chemical, and biological processes are used and treated wastewater is produced which is safe enough for release into the environment. From Dutco Tennant LLC, you can be assured the get the most qualified range of products for wastewater treatment projects.
The dewatering unit, Filter Press is used to reduce the moisture content of the sludge and biosolids. The fixed volume, recessed plate filter press comprises series square plates, recessed on both sides which are supported face to face in a vertical position on the frame with a fixed and moveable head. Over each plate, filter cloth is hung or fitted. The plates are held together with sufficient force to seal them to withstand the pressure applied during the filtration process.
A filter press is mechanical equipment that achieves solid-liquid separation of slurry using pressure filtration with the help of filter plates and clothes. Filter presses are the parts of batch operations and are commonly used for sludge dewatering in municipal and industrial wastewater treatment plants because of their economical and easy-to-operate design. They generally comprise of metal components, plates and filter clothes and the metal components serve the purpose of protecting the filtration unit from pressure applied during operation. The filtration unit is the part of the equipment that can separate solid and liquid in filter presses. This unit is composed of the plates having the same sizes. The filter clothes are worn on each plate to obtain a filtration unit. The filter clothes are there for allowing the water present in the slurry to pass through the pores of the clothes and collect sludge cake on the cloth. The dewatering ratio of filter press is more than decanter’s and belt press which are the equipment used for the same purpose. The main working logic is based on that the slurry to be dewatered passes through the plates inside the filter press and the sludge cake behind. Afterward, the sludge cake is discharged from the system. The sludge cake discharge can be designed as an automatic or manual depending on the requirement of the customer.Features and Benefits –
