Wastewater Testing

Do you know that waste water testing is essential for your business to ensure that it does not contaminate and pollute the environment? Wastewater from commercial properties, agriculture, industry and manufacturing units can contaminate land and pollute water. It is crucial to analyse and treat it before being discharged in the environment, besides it is important that it should be compliant with regulatory requirements.

Importance of Wastewater testing in laboratory

• The laboratory can give solutions to ensure operational control at wastewater plants.
• To ensure that wastewater discharge of industrial users is under the limits set by MoEF&CC along with CPCB.
• Saves additional treatment cost thereby reducing chances of penalty and licence ban of industrial units.
• For wastewater monitoring to prevent epidemics.
• Laboratory experts play a crucial role in quantitative measurement of wastewater constituents in different stages of treatment.
• Accurate measurement of ammonia, phosphorus, and faecal coliform to evaluate the efficiency of the treatment process.
• Measurements of dissolved oxygen, pH, and temperature in the activated sludge basins.

Harmful impact of improper wastewater treatment

• Chemical contaminants in wastewater affects aquatic life
• Bioaccumulation of chemicals in the food chain.
• Untreated sewage wastewater contains E. coli, shigellosis, typhoid fever, salmonella, and cholera.
• diarrhoea, liver failure, urinary tract infection, blindness, helminth infections, hepatitis, schistosomiasis and trachoma.
• Contamination of water sources by faecal matter, chemical contaminants.

A glance at few industries which requires wastewater testing

• Brewery, winery, and soft drink manufacture wastewater treatment
• Baking and confectionery, ready meals and vegetable production and packaging manufacture wastewater treatment
• Commercial laundry wastewater treatment
• Cosmetics manufacture production and packaging wastewater
• Fish processing wastewater treatment
• Paper mills wastewater treatment
• Petrochemical wastewater treatment
• Pharmaceutical wastewater treatment
• Textile manufacture wastewater

We analyse for a wide range of contaminants, including:

• COD, BOD, Dissolved Oxygen, Ammoniac Nitrogen, Oil & Grease, Sodium, Potassium, Colour
• Total Hardness, Total Alkalinity, Total dissolved solids, Total suspended solids, Total Phosphate
• pH, Conductivity, Turbidity, Temperature, Acidity, Calcium Hardness
• Phenol, Chloride, Nitrate, Volatile solids

Need for wastewater testing

Commercial and industrial waste requires specific testing for contaminants to ensure that it is free from harmful contaminants before disposing it in the environment.

Turnaround time

It takes 6-7 days for analysis of microbiological parameters and 3-4 days for chemical parameters.

Method limit

The limits are specified as per the industry type under common guidelines defined by CPCB. The APHA (American Public Health Association) method is used for wastewater analysis.
