Effluent Treatment Plants Vs Sewage Treatment Plants

Water is a limited resource and so when we use the water, it results to polluting the water further. This effluent water is a problem because it must undergo treatment so it can be made safe for the environment before they can be discharged again. There are two main types of plants used for this treatment: A Sewage Treatment Plant and Effluent Treatment Plant. But both plants clean water, however the procedures and the purpose may slightly differ one from the other.

What is an Effluent Treatment Plant and how does it work?

Effluent treatment plant or commonly called as ETP is an industrial application that is used in treating effluent. A number of industries for instance the factory industries, chemical industries, textile industries, among others let out their wastewater that often contains pollutants like chemicals, oil amongst other things. If this particular water is discharged into river or lakes without going through the process of treatment then it will have very adverse effects. To make the water safe to discharge back into the environment, ETPs remove such impurities from the water.

What do you understand about Sewage Treatment Plant?

Sewage Treatment Plants or STPs are used for the purpose of dealing with the domestic wastewater that is released from homes, offices, public places and other establishments. This water contains stool, soap, carry food particles, essential biological tissues, and many more. These water undergoes one more physical and chemical treatment in the STPs to remove unwanted bacteria and wastes to be released back into the environment safely.

Main Differences between ETPs and STPs

While both ETPs and STPs aim to clean wastewater, there are some key differences between the two:

Type of Wastewater Treated

· ETPs: Treat industrial effluent, which can contain chemicals, oil and metals.

· STPs: Purify domestic wastewater that is mainly composed of organic materials and human waste.

Treatment Processes

· ETPs: Separate them by using physical, chemical, and biological methods to eliminate pollutants within the water.

· STPs: Depend more on biological systems to decompose those matters and eliminate unpleasant bacteria and bugs.

Complexity and Cost 

· ETPs: Frequently more sophisticated and expensive to run as a result of the diversity of pollutants often encountered in industrial effluents.

· STPs: Usually technologically less complicated and cheaper than the incinerators handling complex and more dangerous waste.

Regulatory Requirements

· ETPs: They have to conform to regulatory provisions that make certain that most industrial contaminants are well treated and eradicate from the water being released.

· STPs: Also adhere to regulatory authorities, but they are in this case directed to eradicating organics and infection-causing agents to ensure public health.

Advantages of Effluent Treatment Plants

ETPs offer several benefits, especially for industries:

· Environmental Protection: From treating industrial wastewater, ETPs ensure that toxic substances do not finds their way into the rivers and lakes and affect the life of water-borne organisms.

· Regulatory Compliance: Business establishments require compliance to stringent environmental legislations. Such rules are cumbersome to meet, but ETPs assist organizations in meeting them and in the process help dodge fines and other legal troubles.

· Resource Recovery: Some ETPs are useful in the recovery of substances such as metals from the waste water to be recycled for industries.

· Safe Disposal: It also helps ETPs ensure that the water that they will be discharging is safe for disposal, thereby limiting pollution.

The benefits of Sewage Treatment Plants

STPs are crucial for maintaining public health and environmental cleanliness:

· Public Health Protection: STPs remove bacteria and viruses of domestic sewage water and hence control the spread of diseases.

· Environmental Conservation: They help in avoiding polluting the rivers, lakes and the oceans; they treat the sewage before it can be released.

· Water Reuse: That water from STPs can be treated or arranged in a way that such uses as watering plants or washing the car does not use drinking water.

· Odor Control: STPs are useful in eliminating bad smells from untreated sewage thus enhancing lifestyles in the human settlements.

Industry Applications where ETPs and STPs are Applied

Effluent Treatment Plants (ETPs):

· Textile Industry: For reacting with dyes and other chemicals employed in the processing of fabrics.

· Chemical Plants: To remove unwanted reaction products and other contaminants, so that the liquid phase of the mixture could be safely discharged.

· Food and Beverage Industry: For the purification of wastewater resulting from production activities.

· Pharmaceutical Industry: In order to cut the amount of poisonous compounds produced in the course of manufacturing.

Sewage Treatment Plants (STPs):

· Residential Areas: For Sewage from House and Apartments.

· Commercial Complexes: For the effective collection of wastes from offices, malls, and hotels.

· Municipalities: For treatment of sewage generated from cities and towns in general.

· Hospitals: For safe handling of waste originating from hospitals and other medical facilities.

Conclusion

ETPs and STPs are two important systems required to handle wastewater but they have their own functions. There is the need for industries that generate hazardous waste to use ETPs to avoid further emission of chemicals to the environment. STPs on the other hand are used for the treatment of communal sewage from our homes, industries, etc to decrease the spread of diseases as well as to maintain healthy surrounding.

A comparison between these two kinds of treatment plants enables one to realize the approximate functions of these plants in protecting our water sources and the environment. Whether it is a factory that produces heavy products, or a residential area for people to live in, it is essential to have proper wastewater treatment solution for a better world.
