Overview of Waste Water Testing Services

India has a population of 1.3 billion and is considered one of the most water-stressed states, as per the NITI Aayog report from 2018, with approximately 600 million of its citizens facing water scarcity. The report further reiterates that by 2030 India will be facing severe water scarcity and will lose approximately 6% of the country’s GDP. These statistics cement the fact that India is on the verge of the worst crisis, making it the priority for the state authority as well as all the stakeholders to conserve and manage our water resources for a sustainable future.

According to the UN Waste Water Assessment Programme report, around 70% of the Wastewater generated is treated by high-income countries, which further reduces to 38% for upper-middle-income countries, 28% for lower-middle-income countries, and 8% for low-income countries.

Though India does not have a specific policy that regulates wastewater management at the central level, under the Water (Prevention and Control of Pollution) Act, 1974, which was the first law that deals with water pollution and conservation, the Central Pollution Control Board and State Pollution Control Board have the authority to frame guidelines regarding conservation of water. The State Pollution Control Board have the power to inspect sewage and trade effluents as well as Waste Water Testing Service.

Waste Water is produced by Industries (Chemical and commercial), and Agriculture can pollute land surface and groundwater. The wastewater discharged by industries falls under the domain of the Ministry of Environment, Forest and Climate Change, as well as the Central Pollution Control Board.

The Objective of Waste Water Testing Service

The main objective of the Waste Water Testing Service include: -

1. Making wastewater available for other purposes
2. Improving the overall quality of water by determining the pollutants and treating it
3. Eliminating the toxic substances and other pollutants from the wastewater through wastewater treatment.
4. The wastewater is discharged chiefly into another waterbody which further pollutes the water resource; therefore, water management is essential to preserve the quality of water of our natural resources.
5. At last, the objective of water management is to prevent harmful diseases from

Fixed Parameters Set by the Government

The government, as per Central Pollution Control Board, has set fixed parameters for Wastewater within their limits: -

1. For salt pans, shell fishing, mariculture and Ecological sensitive zone

2. For industrial cooling, recreation (non-contact), and aesthetic

Procedure for Waste Water Testing

The process for Waste Water Testing Service from industries and households from food, beverages, chemical, pharmaceutical, and other manufacturing waste.  The testing facilities are regulated by Central Pollution Control Board and State Pollution Control Board.

Waste Water Testing Service by a laboratory

The wastewater constituents are analysed at various steps of treatment done by laboratory professionals, which contributes mainly to the competent process of wastewater treatment plants.

The other industries which benefit from lab testing are: -

1. Commercial laundry industry wastewater
2. Construction & Demolition industry wastewater
3. Cosmetic manufacturing and packaging wastewater
4. Clinic & Hospital wastewater
5. Hotels, Dhaba's, Restaurant wastewater
6. Textile industry wastewater
7. Automobile Services station industry wastewater
8. Confectionery, beverages, and soft drink industry wastewater
9. Fish production industry wastewater
10. Papermill/Printing industry wastewater
11. Pharmaceutical industry wastewater
12. Readymade mixing concrete (RMC) plant wastewater
13. Electroplating industry
14. Petrochemical Industry

Importance of Laboratory Waste Water Testing Service

• Testing water generated from various sources contain a high number of toxic containments to safeguard us from the atmosphere and health risks.
• The testing lab makes sure that wastewater discharged is regulated as per the guidelines set by The Ministry of Environment, Forest and Climate Change, and Central Pollution Control Board.
• Accurate and Quantitative measurements of all the wastewater constituents.
• The testing laboratory gives a solution to make sure to control wastewater at the plant.

The range of parameters in wastewater with the limits set by the CPCB guidelines are:

• The size of suspended solids should pass 850 microns IS Sieve
• pH value must be between 5.5 to 9.0
• the temperature must not exceed 5 degrees Celsius above the receiving water temperature
• total Nitrogen must not exceed 100mg/l
• arsenic maximum 0.2 mg/l
• Ammoniacalal Nitrogen should not be more than 50 mg/l.
