Introduction Water is one of our most important natural resources. Water is used in different purpose such as domestic‚ industrial supply‚ transportation‚ recreation. However‚ nowadays‚ humans are continuously deteriorating rivers‚ lakes‚ and oceans through different agricultural‚ industrial activities. Abel (1996) states that water pollution defines as “the addition of undesirable materials into aquatic bodies” (p.1). This may cause physical‚ chemical or biological change in water‚ leading to different

Water‚ that magical substance from which all life springs forth‚ is essential to the very existence of every life form on earth. The role of water in the living organism has not changed since life’s first creation in salt water billions of years ago. The human body is 75% water‚ while the brain alone is comprised of 85% water. The blood‚ consisting of 92% water‚ carries oxygen and essential nutrients to capillaries where they are released into a water-based fluid that surrounds the cells called

Whether it’s streams‚ rivers‚ lakes‚ or the ocean‚ countries have taken great measures to maintain a high quality of water for both human consumption and as a key component to the environment. We deal with the pollution problems and then decide on ways to clean it up. This valuable resource is the key to survival. Both plants and animals depend on water for their growth‚ so the water must be kept clean

How water is purified in water treatment plants Pre-treatment 1. Pumping and containment – The majority of water must be pumped from its source or directed into pipes or holding tanks. To avoid adding contaminants to the water‚ this physical infrastructure must be made from appropriate materials and constructed so that accidental contamination does not occur. 2. Screening (see also screen filter) – The first step in purifying surface water is to remove large debris such as sticks‚ leaves

oversight have increased water pollution. Therefore‚ deterioration of drinking water quality continues to be a major problem. Continuous emissions from manufacturing are the largest contributor to lowered drinking quality across the country. China’s major river systems exhibit the scope of the problem. Perhaps 70 percent of their water is so polluted that it has been deemed unsafe for human contact. In addition to untreated sewage released into these waterways‚ high-growth industries such as textiles‚ paper
