  • How to improve sludge dewatering process in wastewater treatment plants?
  • Sludge dewatering is an expensive operation in wastewater treatment plants. It is not possible to improve the dewatering process by applying higher pressure in filtration processes due to the high compressibility of sludge cakes.
  • What is sludge dewatering?
  • Sludge dewatering is the fundamental process of sludge treatment. Environmentally friendly and efficient sludge conditioning methods are the premises of sludge to achieve dehydration reduction and… Response of extracellular polymeric substances to thermal treatment in sludge dewatering process.
  • What are the methods used for treatment of contaminated water?
  • Methods used for treatment of contaminated water in order to meet the acceptable standards are called wastewater treatment process (Rathi et al., 2021). Several wastewater treatment processes include physical, chemical and biological techniques. During biological treatment, waste water is treated using micro-organism instead of chemicals.
