Abstract
Water is the most important resource for all kinds of life on this earth. Water pollution is the contamination of water bodies (i.e. rivers, oceans, lakes, and ground water). Water pollution occurs when pollutants are directly or indirectly discharged into water bodies without treatment to remove harmful compounds. Water pollution and its treatment are interconnected to each other so it is not possible to explore one topic without the other. Today, all over world, people suffer from this problem so scientists and researchers are trying to solve these problems by different ways. There are many chemical and biological methods for water pollution treatment. This chapter deals with a brief introduction about water pollution, its types, main reasons that cause water pollution, and their effects on human health and environment, and it is mainly focused on the waste water treatment processes by bioremediation and chemical methods for removing heavy metals, pesticides, organic compounds, and dyes, which are mainly found in industrial and domestic waste water.
