What is sludge class 7 chemistry

The Chapter 18 of NCERT Solutions for Class 7 Science guides students to segregate waste which leads to reduction in water pollution. The importance of water in balancing the ecosystem is demonstrated clearly in this chapter. By using the solutions, students will get a clear idea about the meaning of sewage, treatment and disposal methods This is the sludge. A skimmer removes the floatable solids like oil and grease. Water so cleared is called clarified water. The sludge is transferred to a separate tank where it is decomposed by the anaerobic bacteria. The biogas produced in the process can be used as fuel or can be used to produce electricity Sludge The settled solids, after primary treatment, are called the sludge. It is decomposed by bacteria and the gas emitted is known as biogas, which can be used as a fuel or can be used to generate electricity Explain how it is treated. Ans. Sludge is the collected solid waste from the wastewater during the treatment in water treatment plant. Sludge is decomposed in a separate tank by the anaerobic bacteria. Activated sludge is used as manure

  5. All three of the tested additives yielded passing sludge formation results, though a slight degradation in sludge control was observed with PO-PEA at the higher concentration. Analysis of the used test oil demonstrated that the BO-PEA chemistry led to a 73% improvement in oxidative stability, when compared to used oil from PO-PEA testing
  6. Sludge is a semi-solid slurry that can be produced from a range of industrial processes, from water treatment, wastewater treatment or on-site sanitation systems. For example, it can be produced as a settled suspension obtained from conventional drinking water treatment, as sewage sludge from wastewater treatment processes: 23-25 or as fecal sludge from pit latrines and septic tanks
