ABSTRACT

Water pollution is defined as pollution created in water by adding one or more constituents that modify water in a way that causes problems to humans, animals, and the environment. The major concern of water pollution is the chemicals with it, which has become a priority for society and public specialists and, most importantly, the industrial world responsible for these problems. Established conventional wastewater treatment processes to remove solid pollutants are combinations of physical, chemical, and biological processes that help reduce or eliminate soluble contaminants, nutrients, organic and inorganic materials, etc. from effluents. Apart from these technologies, new emerging methods—including reverse osmosis, membrane filtration, bioaugmentation, algal treatments, etc.—has been established to obtain a higher quality of liquid effluent, which can be recycled. The selection of any conventional or modern treatment method depends on the characteristics of the effluent discharged and, most importantly, less consumption.
