Best Practice Guide on the Control of Arsenic in Drinking Water

Dec. 15, 2015

This Best Practice Guide on the Control of Arsenic in Drinking Water arises from the knowledge collected by the European Research Network COST Action 637 involving 27 European countries and the USA. Besides the large number of important papers, reports and reviews already available on various aspects of arsenic occurrence in environment, water and food and related human exposure, this book fills a gap in the field concerning assessment of risks, implications, challenges, and actions required by public health managers. It focuses only on the key aspects of risk assessment, management and communication relevant to higher levels of arsenic in drinking water, which are geological factors, the extent of arsenic occurrence, total exposure of arsenic and the role of drinking water, including regulatory aspects as well as technical (treatment) issues. The Best Practice Guide on the Control of Arsenic in Drinking Water tries to raise public awareness on this subject, which seems to be low and risks are being underestimated in a number of regions. This is especially valid for Europe although less for other regions which are typically more contaminated with arsenic. The referred practices conform to the recommendations of the World Health Organisation (WHO), the European Food Safety Authority (EFSA) and the U.S. Environmental Protection Agency (EPA). It is a useful guide for drinking water suppliers, experts of municipalities, public health authorities, drinking water regulators and non-governmental organisations.

The effluent generated from different sections of a textile industry must be treated before they are discharged to the environment. Various chemicals and physical means are introduced for this purpose. Some chemicals are used to treatment those wastage polluted water. Here chemicals name are given which are used in effluent treatment plant. Required Chemicals and Their Functions in Biological ETP: H2SO4: Function: Neutralize the waste water controlling the PH. It is auto dispensed in the neutralization tank. Polyelectrolyte: Function: Used for sedimentation / sludge coagulation and also killing bacteria. Antifoaming Agent: Function: Used for reduction / controlling foam. It is used auto / manually in the distribution tank. De-colorant: Function: Used for removing color. It is used auto / manually in the sedimentation feeding tank. Sodium Hypochlorite: Function: It is used to kill the harmful bacteria. It is used in the biological oxidation tank. Product Quality Checked: 1. Biological Oxygen Demand (BOD) 2. Chemical Oxygen Demand (COD) 3. Total suspended solids 4. Total dissolved solids 5. Color 6.
