How Do Sewage Treatment Plants Work?

 Wastewater treatment is an addition to the natural process of water purification. To maximize the use of natural resources, wastewater treatment plants are organized and implemented. Industrial wastewater treatment plants and sewage treatment plants are used to purify water and make it useful again.

Most commonly, two methods of wastewater treatment are used to fulfil the demand of citizens, industry, and communities. How do these two different methods work?

The most common method used in wastewater treatment is the activated sludge process (ASP). The ASP method has four stages: pretreatment, primary clarification, biological oxidation, and final clarification.

Pretreatment is done through screens or grit chambers to remove large objects such as cans, bottles or rags from sewage water. The primary clarification is a sedimentation process that separates solids from liquids. Biological oxidation is where microorganisms biodegrade organic materials in the sewage water using air diffused into the liquid stream through sparkers or mechanical aerators. The final stage is where suspended solids are removed from effluent to produce a high-quality effluent called secondary effluent or reclaimed water.

The Sharp Engineering Works aims to treat the domestic and industrial effluents to make them suitable for disposal without any further harm to the environment. Reducing the amount of water available is a necessity to make precious fresh water available for all purposes. This leads to the use of less fresh water in the activities and industries which are water guzzlers. Thus reduced freshwater consumption leads to lesser pollution of freshwater bodies through the discharge of treated effluent into them.
