Published by : Data Research Analyst, Worldofchemicals.com

The volume of waste water has increased due to the exponential increase in population. Apt disposal methods must be in place in order to tackle the wastewater nuisance. Wastewater treatment is engineered to remove solids, both organic and inorganic from the wastewater. This facilitates the proper disposal of waste water without violating the set goals.

 

Choosing the apt commercial waste water treatment system

Choosing the right wastewater treatment system for commercial purposes is a complex process, which involves time and research. An apt wastewater treatment method must withstand the time test on low capital and running costs. The wastewater treatment method must meet the regulations and standards for environmental health and protection. The wastewater treatment systems must be thoroughly tested based on the specifications and have the least impact on the environment. The installation process and subsequent maintenance of the commercial wastewater system must be easy.

 

Various Treatment Methods 

Commercial methods for wastewater treatment include physical, biological and chemical methods. These wastewater treatment methods are discussed in detail in the further sections.

 

1. Physical Treatment Methods

Physical treatment methods involve screens, strainers, membranes, filters and sedimentation tanks. These methods are effective in getting rid of large entrained objects from wastewater and sewage.

Sedimentation is a widely used method for wastewater treatment deployed at the beginning of the treatment process. In the filtration method of wastewater treatment, a filter medium is used to filter solids from wastewater. Floating method is used to remove oils and greases, which can be physically removed or skimmed from the wastewater. 

 

2. Biological Treatment Methods

In biological methods of wastewater treatment, there are two methods. One is aerobic and another is the anaerobic method, which is based on the presence of dissolved oxygen in the wastewater.

The aerobic wastewater treatment method is carried out in the presence of oxygen, which involves the effective breakdown of organic matter, thereby resulting in purer water effluent. There are many aerobic treatment methods such as activated sludge process, aerated lagoons, trickling filter and oxidation ponds.

The anaerobic wastewater treatment method is carried out in absence of oxygen. It is used to treat high strength sewage and wastewater with the help of functional organisms.

 

3. Chemical Treatment Methods

Chemical treatment methods are associated with wastewater treatment chemicals and their reactions to enhance the quality of water. Chlorination is one of the most widely employed chemical treatment methods for wastewater and sewage. Chlorine is an oxidizing agent, which is used to kill bacteria and retard the wastewater decomposition rate.

Aluminium sulfate or alum is a chemical compound used as a coagulating agent in the treatment of wastewater and sewage, manufacturing of paper and purification of drinking water.

Sodium hypochlorite is another chemical compound effective for large scale commercial wastewater and sewage treatment, which is known for its strong bleaching, odal elimination and water disinfection characteristics.

Ferrous chloride finds many wastewater and sewage treatment applications owing to its effective coagulation ability.

Other commercial methods of waste treatment are neutralization, adsorption, reduction, oxidation, precipitation and ion exchange method.

You can buy chlorine, aluminium sulfate, sodium hypochlorite and ferrous chloride from the top global suppliers through our leading chemical portal.

 

Conclusion

All aspects are not considered in the wastewater treatment process. Government agencies across the globe should ensure smooth operation and proper designing of wastewater treatment plants, such that costs and energy are optimally cut down. All concerned stakeholders must put more efforts on the maintenance of wastewater treatment plants. This will enhance the quality of treated wastewater and result in a better and cleaner environment.
