Why Do We Treat Drinking Water ?
Drinking water is treated to protect public health by removing microorganisms and natural or man-made chemicals that may cause illness to consumers.
Water Purification may also be used to improve the water’s color, taste, and odors required.
- Water quality is the physical, chemical, biological characteristics of water that determines its suitability for a variety of uses and for protecting the health.
- Water quality depends on the local geology and ecosystem, as well as human uses such as sewage dispersion, industrial pollution, and agriculture runoff.
- Water is essential to sustain life, and a satisfactory supply (adequate, safe, and accessible) must be available to all. Improving access to safe drinking-water can result in tangible benefits to health
- The great majority of evident water-related problems are the result of microbial (bacteriological, viral, protozoan, or other biological) contamination.
- World Health Organization has set the Guidelines for Drinking-water Quality of which the primary purpose is the protection of public health.
Basic Parameters of Water
- Dissolved oxygen (DO)
- Chemical oxygen demand (COD)
- Biochemical oxygen demand (BOD)
- Inorganic Chemicals (Metals, minerals, and nutrients)
- Organic Chemicals (Pesticides, Benzene, etc.)
- Pathogens (Viruses, Bacteria, Protozoa, etc.)
- Fecal Coliforms
