As a result of the ample supply of highly toxic and hazardous refractory organic, inorganic, and organometallic compounds. pathogenic microorganisms and chemical elements including heavy metals, which reach distant areas due to the medium of dispersion and thereby create an ecological discomfort and harmful health hazards in life forms, wastewater generated from various sources such as municipal, domestic, and industrial activities is the primary global environmental concern. Although it is currently impossible to prevent wastewater from being released into the environment, it is possible to mitigate its gravely detrimental impacts on people and the entire ecosystem by treating the wastewater using a variety of techniques. Therefore, before the wastewater is disposed of into the environment, sufficient treatment is necessary. 

 Integrated wastewater treatment 

By combining two or more biological, physical, and chemical processes, integrated treatment techniques have been used extensively to treat/eliminate undesired color, target chemicals, and toxicity from wastewater or polluted environments. 

 Types of wastewater treatment 

Three stages are used to remediate wastewater: 

Primary Treatment 

Sewage is placed in a basin during initial treatment so that solids (sludge) may fall to the bottom and oil and lighter materials can rise to the top. The residual liquid can then be sent for further treatment once these layers have been removed. Sludge digestion is a distinct procedure used to remediate sewage sludge. 

Sludge Digestion 

During initial treatment, sewage sludge that was scraped from the bottom of the settling tank is better handled from wastewater. 

Secondary Treatment 

The removal of floating and dissolved biological materials during secondary treatment frequently involves the use of microbes in a controlled setting. 

Tertiary Treatment 

Water that is being released into a delicate ecology undergoes tertiary treatment, often known as "effluent polishing."   

 Sewage treatment Plant and its procedures 

The process of purifying sewage water and reusing it for gardening, agriculture, and other general purposes is known as a sewage treatment plant (STP). 

Here are a few STP procedures: 

• Activated Sludge Process. 

• Moving Bio Bed Reactor (MBBR) 

• Membrane Bio Reactor (MBR) 

• Electro Coagulation System. 

• Sequential Bio Reactor (SBR
