Industries make an essential contribution to economic development, however, they also produce large volumes of wastewater, which is usually polluted with toxic chemicals, oils, and heavy metals. To be environmentally friendly and achieve compliance with regulations many industries put ETP in operation. These are plants which carry out the industrial waste water before reuse in operations or discharge into the environment.
Significance Of Effluent Treatment Plant For Automobile Industry
Effluent treatment plant fot automobile industry particularly is very critical in relation to nature of pollutant deposits produced in the manufacturing processes. Surface coating, engine washing, painting and metal finishing are examples of processes that disseminate a wide variety of contaminants. These are grease, heavy metals such as chromium and lead, suspended solids and toxic chemicals which are both harmful to the environment and human health.
Failure to treat this wastewater appropriately can otherwise cause serious ecological degradation when the wastewater is discharged into natural water bodies. An ETP assists in counterbalancing or neutralizing these pollutants so that the waste water can be of the required standards in regard to the required environmental standard.
What is the working of an effluent treatment plantfor automobile industry?
The use of ETP normally entails several steps of treatment:
1. Preliminary Treatment: Large solids and grit are screened out by means of screens and grit chambers.
2. Primary Treatment: The nature of this stage is separation of solid particles in liquid waste through physical processes e.g. sedimentation.
3. Secondary Treatment: The use of biological methods through bacteria to degrade organic pollutants are used.
4. Tertiary Treatment: This is a highly sophisticated level at which remnants of the contaminants are eliminated by the use of chemicals and a filtration system which eliminates traces of heavy metals and pathogens.
The filtered water may then be reused or discharged safely into the ocean or the many faces of industry including cooling or cleaning.
Advantages to Effluent Treatment For Automobile Industry
There are a number of benefits of implementing an effluent treatment plant to automobile industry:
• Regulatory Compliance: Regulatory compliance ensures that it does not incur any cost by not complying with law.
• Environmental Protection: Assists in preservation of water bodies and environment where the users conduct their activities.
• Resource Savings: The treated water can be returned and water-saving is possible.
• Better Company Image: Shows social responsibility towards sustainability and environmental care.
An effluent treatment plant is not only a regulatory requirement but is an important part of sustainability of an industrial operation. Where natural wastewater contains a complex blend of waste substances, such as in the automobile industry, the ETPs have a crucial role in the minimization of environmental footprints.
By putting the investments into the right treatment solutions the environmental safety would be secured and additionally it would help ensure the viability and business reputation on the long term.
