Water treatment process is usually divided into various stages. This is done with intention improving the quality of output. In preliminary stage, large filtering screens are used to ensure large solid materials are removed. Items removed during this stage include; papers, metals, plastics, silt and grit. Second stage in Industrial Wastewater Treatment plant is primary stage. During this stage, organic materials are removed by passing waste water through sedimentation tank (primary). Wastes are removed using both biological and physical processes.

This second stage ends at secondary sedimentation tank. Within this tank sludge is formed when biomass settles. Clear water forms on upper part of tank. This water is then allowed to move to tertiary treatment stage. This is actually the third stage. Here pathogens present in clear water are killed using appropriate chemicals. This process is usually repeated many times, in case water is to come into contact with individuals.

Although, wastewater treatment is an expensive procedure, untold benefits are enjoyed, if process is conducted appropriately. Process ensures that water consumed by people is not only clean, but also safe for human consumption. Procedure plays an important role in improving the comfort of individuals. Benefits increases tremendously in case, process is carried out in correct manner. Fewer benefits are likely to be realized, in case, management is not done as expected.

Some of waste materials collected during this process, are recycled. This means process helps in reducing amount of wastes produced by members of a given country. This is beneficial because more jobs of citizens are created in recycling industries. Furthermore, procedure leads to formation of environment, which is not only healthy, but also comfortable to live in. Dangers brought about by occurrence of wastes in environment are prevented owing to elimination of environmental pollutants.

Most importantly, this procedure plays an essential role in reducing water pollution. This is accomplished as a result of removal of both inorganic and organic solids from water. This impacts health of aquatic animals and of people positively. Amount of money spent by authority in financing projects intended keep environment clean is reduces drastically, if appropriate methods are used when treating wastewater.

Sludge collected during the treatment process is very beneficial. It contains a lot of biodegradable materials. Such materials are treated using aerobic bacteria within enclosed digesters at appropriate temperatures. These kinds of microorganisms thrive excellently hence producing gases, which contain high percentage of methane. Methane is then harvested using appropriate procedures and then used to generate electricity. This shows the process can help in energy production.

Biodegradable material collected within the tanks during primary stage can be dried, hence forming natural fertilizer. In most cases, drying is usually done within drying lagoons so as to acquire pleasing results. Resulting fertilizer can be applied in agricultural sector to increase crop yields. This leads to reduction in the usage of chemical fertilizers, which pollute the surroundings.

Water treatment also plays an important role in ensuring people live healthy life. This enables them to work hard with minimal challenges hence improving their life standards. Most importantly, when there are fewer diseases, it means there are fewer deaths. This leads to increased labor force hence improvement in economy of a company.
