filter press

  With more than 30 years of experience in the development and manufacture of   drum thickeners , Filter has gained in-depth expertise in sludge thickening technology. Rotary drum thickeners for sludge thickening are considered a simple and effective sludge thickening solution prior to the dewatering process and can handle 15 to 180m³ of biological sludge per hour. Due to their simple design and small footprint, drum thickeners for   sludge thickening  are easy to install and require little supervision and maintenance.   Rotary drum thickener  for sludge thickening before dewatering   The drum thickener is used for sludge concentration. Its spray pipe is easy to access and easy to maintain. It can ensure dynamic concentration by continuously rotating the sludge. It is professionally designed for sludge pre-digestion treatment (for primary sludge and secondary sludge). or deep treatment of sludge). It can also be used to reduce the hydraulic load o...

  A typical urban   sewage treatment  process mainly includes mechanical treatment, biochemical treatment, sludge treatment and other sections. The system composed of mechanical treatment and biochemical treatment is a secondary treatment system, and its BOD5 and SS removal rate can reach 90% to 98%. The treatment effect between primary and secondary treatment is generally called enhanced primary treatment, primary and a half treatment or incomplete secondary treatment. There are two main categories: high-load biological treatment and chemical treatment. The BOD5 removal rate can be Reaching 45% to 75%. Secondary treatment systems with biological phosphorus and denitrification functions are often called deep secondary treatment. In order to remove specific substances, the treatment system set up after the secondary treatment is a tertiary treatment, such as chemical phosphorus removal, flocculation filtration, activated carbon adsorption, etc.   The oxidation ditch p...
