Although local water supplies are purified to minimize the presence of contaminants, such as bacteria, lead, mercury and pollutants yet, these impurities at many instances and due to certain factors like accidents or through the improper disposal of certain materials again mix up with water. However, the major objective of wastewater treatment is to remove impurities or lessen their quantity to a concentration that means the water is safe to drink. There are many top reasons why you need to treat water

Reasons for wastewater treatment

  • Health Benefits– Although tap water is safe to drink, yet it contains a lot of contaminants causing a plethora of water-borne diseases like cholera, diarrhea, fever, and other infections. You will even feel sluggish and tired when you drink this water to keep yourself hydrated.
  • Improved taste – Water with minerals and impurities also affect the flavour. Many instances it gives a metallic taste or unpleasant taste. However, purifying wastewater using wastewater treatment plant can improve the flavour of drinking water without having to boil it.
  • Reduced volume of minerals like lead and chlorine-Mineral presents in the water leads to many health hazards. Many skin problems arise as a result of taking a shower or swimming in the water that contains minerals like chlorine. Even chlorine is a major contributing problem for hair loss.

In order to get rid of these situations, wastewater treatment is a suitable choice. There are many types of wastewater treatment systems however only a few are found to be prominent. Many regulatory authorities basically specify how frequently wastewater should be examined, and also the methods used, executing periodic reviews and spot checks to guarantee safety level. When the wastewater treatment companies fail to adhere to these principles, they are subjected to severe penalties or prevented from operating their business.

There are only certain chemicals permitted for the removal of contaminants from the wastewater. Chemicals used to remove specific wastewater contaminants include

  • Aluminium sulphate (alum)
  • Aluminum Chloride Solution
  • Liquid sodium aluminate
  • DelPAC
  • DelPAC XG

These chemicals act as pH neutralizers, anti-foaming agents, coagulants and flocculants depending on the process. The types of wastewater treatments are

  • Effluent Treatment Plants – It is specifically developed to disinfect industrial wastewater for recycling and its objective is to provide drinking water to the environment against the harmful effluents present in the water
  • Sewage Treatment PlantsSewage water treatment requires primary, secondary and tertiary treatments to remove contaminants and produce treated wastewater that is safe to use for drinking and other household purposes.
  • Common and Combined Effluent Treatment Plants– This wastewater treatment plan is commonly adopted in small scale tanneries that can potentially help in achieving treatment of combined wastewater from effluents.
  • Activated Sludge Plant-It is a procedure dealt with the purification of sewage water treatment and manufacturing wastewaters using aeration and an organic floc comprising of bacteria and protozoa.
