Sewage Water Treatment: A Guide

Waste water treatment has close association with expectations and standards entailed in effluent quality. The processes involved are designed in a way that attains required levels of improvement in the quality of treating waste water. Many of the processes applied in sewage water treatment aim at achieving several benefits.  Learn more about sewage treatment facility, go here. 

First, they minimize suspended solids. These are physical crystals that clog channels and rivers once they settle under the base. They also reduce biodegradable organics. These organics act as food for microorganisms in the body that receives them. In the end, the microorganisms use the oxygen available in water to produce energy used by the organisms to reproduce and increase in number. On the flip side, the same oxygen is required by fish as well as other aquatic plants and organisms.  Find out for further details on household wastewater treatment right here. 

Intense organic pollution breeds a dead zone. This is where no valuable aquatic organisms are found. Other values are the reduction of pathogenic bacteria and nutrients. There are three levels of waste water treatment that are commonly used today. Primary treatment is the first method. It is also called the mechanical form of waste water treatment. The technology removes floating and suspended solids as well as gross elements from raw sewage. The process entails screening that traps sedimentation and solid objects by gravity to eliminate the suspended solids. Though called mechanical, chemical processes are used where necessary to speed up the process of sedimentation. 

The second method is referred to as the secondary treatment. In other quotas, it is referred to as the biological waste water treatment. The process removes organic matter dissolved in waste water. The microbes consume the dissolved organic matter considered food and convert the same into carbon dioxide energy, and water. The valuable products are useful to the microbes. Secondary sedimentation, also called additional settling tanks follows this step immediately. It removes additional suspended solids.

The last method is the tertiary form of waste water treatment. It comes as an additional technique on top of secondary. It has the capacity to eliminate almost 100% of all the impurities in waste water. It results in an effluent with almost a 100% drinking quality. However, technology applied at this level expensive. Furthermore, it requires higher-level skills to operate and maintain. Those handling the technology ought to be highly qualified plant operators. Additional requirements for such technology are constant supply of power/energy and specified equipment that use special chemicals. Modification of a conventional secondary treatment facility to remove extra nitrogen and phosphorous is the most notable example of a tertiary waste water treatment technique.
