World Population

The management of industrial and residential effluents is an important factor in large cities across the world. In India alone, the rate of urbanization has increased from 28.6% in 2003 to 31.99% in 2013. According to UN report, over 54% of the world population lived in urban areas in 2014 as compared to 30% in 1950.


Need For Advanced Waste Water Management

With the rising population and urbanization, the quest for better and efficient sewage cleaning systems is increasing. These systems must be designed and installed to withstand increased corrosion and handle more wastes.The effluents are mainly comprised of sulfides, methane, organic substances, ammonia, oxygen, nitrates, phosphates and other materials. The combination of these chemical and organic matter results to unforeseen wearing of pipes, leakages and other damages.


Factors to consider when designing the systems

These effluents have many residential and industrial chemicals that would otherwise corrode many pipe and large containment areas.Due to the large scale of operation, it is necessary to lower corrosion so as to reduce degradation, prevent system failure and minimize maintenance and operation costs. This is achieved through the use of flocculants, inhibitors and, anticipants for different metallic components.


Corrosion Inhibitors in Sewer Management

Corrosion Inhibitors, when applied to sewage pipes and tanks react with these structures forming a surface layer that impedes further wear. The inhibitor adheres to the surface of the equipment forming an oxide that prevents further decomposition.Organic ones form a hydrophilic film on metal surfaces while the precipitating type forms a protective surface of precipitates. Common precipitates include silicates and phosphates.

Useful Properties of Emulsions in These Plants

Emulsion breaking is important process in the management of industrial and domestic wastes.Most agrochemicals, pesticides, surfactants, cosmetics, toothpastes are made using materials that are not miscible in water.Since they are present in sewage, they form emulsions that float on the water. This inert layer prevents chemical and physical waste action on the sewage.
