standard of waste water discharged in india.rongkup
The document discusses wastewater treatment and regulation in India. It defines wastewater and its sources, and explains the harmful effects of discharging untreated wastewater. It then outlines the key treatment processes used, including physical, chemical and biological methods. The Environment Protection Act of 1986 and Central Pollution Control Board establish standards for wastewater discharge. Specific guidelines exist for discharge from shrimp farms and fish processing plants. Proper wastewater treatment, monitoring and enforcement of standards are emphasized to regulate discharge quality.

BOD and sewage water treatment processSamiaSalman1
The document discusses wastewater treatment processes. It describes that wastewater undergoes preliminary treatment to remove solids, primary treatment to remove settleable solids through sedimentation, and secondary treatment using biological processes like trickling filters, activated sludge, or oxidation ponds to further reduce organic matter. It then provides details on the steps and purposes of preliminary treatment, primary treatment, and some secondary treatment options.

Industrial wastewater treatment describes the processes used for treating wastewater that is produced by industries as an undesirable by-product. After treatment, the treated industrial wastewater (or effluent) may be reused or released to a sanitary sewer or to a surface water in the environment. Some industrial facilities generate wastewater that can be treated in sewage treatment plants. Most industrial processes, such as petroleum refineries, chemical and petrochemical plants have their own specialized facilities to treat their wastewaters so that the pollutant concentrations in the treated wastewater comply with the regulations regarding disposal of wastewaters into sewers or into rivers, lakes or oceans.

This document discusses water treatment processes. It explains that water treatment removes contaminants and makes water suitable for various end uses like drinking, industrial use, or safely returning to the environment. It then discusses various sources of water like surface water, underground water, and sea water. Finally, it summarizes common water treatment processes like coagulation, sedimentation, and filtration which use chemicals and gravity to remove suspended particles and make water clearer.

This document discusses coagulation and flocculation processes used in water treatment. It explains that coagulation uses chemicals like aluminum and iron salts to destabilize colloidal particles in water by neutralizing their negative charges. This allows the particles to agglomerate into larger flocs during flocculation. Flocculation is the process where these destabilized particles come together through gentle mixing. Jar tests are used to determine the optimum pH and coagulant dose needed for effective coagulation and flocculation in water treatment.
most important topic for more clearance of water quality standards which covers latest Indian and WHO guidelines and provides a real scenario of water standards in India and the recent advances made for purification of water in India and worldwide. The presentation is little bit lengthy but deals with all required aspects in short.
Routine analysis of wastewaters quality parametersArvind Kumar
This document discusses parameters for analyzing waste water quality. It describes the objectives of waste water analysis which include monitoring treatment plant efficiency. Physical analyses examine characteristics like color and odor, while chemical analyses determine substance amounts. Key parameters discussed include biochemical oxygen demand (BOD), chemical oxygen demand (COD), dissolved oxygen, pH, nitrogen, and solids. BOD testing measures oxygen consumed by bacteria breaking down organic matter over time. COD testing uses chemical oxidization to similarly assess ability to consume oxygen. Their ratio provides information on a waste water's biodegradability.
The document discusses three methods for disinfecting water lines - the tablet method, continuous feed method, and slug method - and provides details on how each method works, factors that influence method selection, benefits and limitations of each approach, and procedures for properly disinfecting lines to eliminate coliform bacteria.
