Water Treatment Plant Process- Chlorination or Ultraviolet Radiation By Shreya Shah Surface waters necessitate water treatment before consumption to guarantee no health risk is present to the user. Poor quality water which consists of dissolved and suspended particles‚ can impact and cause health risks to consumers. The most important contamination is the microbiological contamination as it leads to infectious diseases (Water Treatment‚ 1994). Chemicals such as nitrates and cyanide when contaminate

always present and must be killed before the product is distributed to its customers. While there are several different chemical and nonchemical disinfection methods available for use throughout the water treatment industry including via means of chlorination‚ hypochlorination‚ and ultra-violet light (quickly increasing in popularity)‚ a strict agenda of regulatory guidelines must be closely adhered to. These regulations have been implemented over the years by the federal Environmental Protection Agency

Environmental Engineering Environmental engineering is a field related to direct application of science and engineering principles to the environment in which animals‚ humans and plants are living. An environmental engineer as a professional is concerned to protect the environment from deterioration; he is also concerned with the preservation of resources including plants‚ fuels‚ and fossils which can generate energy for human use. The primary task of an environmental engineer is to provide

Water Recycling Recycled water- is former wastewater that is treated to remove solids and certain impurities‚ and used in sustainable landscaping irrigation or to recharge groundwater aquifers. The purpose of these processes is sustainability and water conservation‚ rather than discharging the treated water to surface waters such as rivers and oceans. Undoubtedly‚ recycling or re-using water can offer very significant economies. One of the greatest obstacles is the fact that much of the wastewater

and industry meets drinking water standards‚ even though only a very small proportion is actually consumed or used in food preparation. Typical uses (for other than potable purposes) include toilet flushing‚ washing and landscape irrigation. Chlorination is the process of adding the element chlorine to water as a method of water purification to make it fit for human consumption as drinking water. Water which has been treated with chlorine is effective in preventing the spread of waterborne disease
