The physical process of wastewater treatment begins with screening out large items that have found their way into the sewer system, and if not removed, can damage pumps and impede water flow. A bar screen is usually used to remove large items from the influent and ultimately taken to a landfill.
This article throws light upon the four processes of waste water treatment. The four processes are: (1) Preliminary Treatment (2) Primary Treatment (3) Secondary or Biological Treatment and (4) Tertiary or Advanced Treatment.
Have you ever wondered what happens to that water and waste after you flush? How about after you pull the plug on your tub? The modern wastewater-treatment plant employs basic physics and high technology to purify the dirtiest of water so it can go back into the environment as a member in good standing of the water cycle.
plants for treatment. Most treatment plants were built to clean wastewater for discharge into streams or other receiving waters, or for reuse. Years ago, when sewage was dumped into waterways, a natural process of purification began. First, the sheer volume of clean water in the stream diluted wastes. Bacteria and other small organisms in the ...

There are numerous ways to treat wastewater, and Figure 1 shows a flow diagram that breaks down the various steps of treatment in the effluent treatment process [7]. Sewage water typically ...
To understand how a wastewater treatment plant (WWTP) works you have to look into all aspects of the water treatment process. The series of processes that occur throughout the wastewaters journey from being untreated influent to it being discharged as a treated effluent often into open water sources.
Wastewater treatment, the removal of impurities from wastewater before it reaches aquifers or natural bodies of water. Wastewater treatment is a major element of water pollution control. Learn more about the types of wastewater treatment systems, the technologies used, and the history of treating wastewater.
However, a typical sewage treatment plant flow diagram is represented in Fig. 1. The aeration basin effluent (also called "mixed liquor") is transferred to the secondary clarifier. Here the...
Thus, wastewater treatment plants with capacities ranging from 8000 to 200,000 tons/day have been implemented to treat wastewater and discharge effluent with improved quality parameters.
