How to identify Wastewater Generating Systems or Sources?
India has abundant water resources, with a network of 113 rivers (not including tributaries) and large alluvial basins that can contains a lot of groundwater. India is also blessed with snow-capped peaks in the Himalayan range that can supply the country's diverse water needs.
However, in both rural and urban India, the most serious environmental problem and hazard to public health is a lack of safe drinking water and sanitation services. Organic pollution and bacterial contaminants have infiltrated almost all surface water sources, rendering them unsafe for human consumption unless cleansed. Typhoid, cholera, gastroenteritis, bacterial dysentery, hepatitis, poliomyelitis, amoebic dysentery, and other diseases are usually caused by contaminated water.
How is wastewater generated?
1: Domestic wastewater is generated by the usage of water in homes, businesses, and restaurants.
2: Wastewater from the manufacturing and chemical sectors is referred to as industrial wastewater.
3: Debris, grit, nutrients, and different chemicals are picked up by rainwater in urban and agricultural areas, contaminating surface runoff water. Floodwater runoff, swimming pool water, garage water, and cleaning center water are all examples of wastewater.
4: Another group also includes non-domestic wastewater from salons, commercial kitchens, energy plants, and agricultural enterprises.
As a result, water consumed in residential, commercial, and industrial units will contribute to the total amount of wastewater produced.
Wastewater Generators identification: Identification of Wastewater generating Sources
The waste streams from both production processes and pollution-control initiatives should be identified during the in-plant survey (e.g., product change washouts, site clean-up, wet air scrubber blowdown, sludge dewatering, boiler blowdown, or secondary containment spillage).
Although some of these waste streams are tiny and discharged infrequently, they can have a significant impact on the overall treatment ability of wastewater. Because of the restrictions and costs associated with off-site disposal, many industrial enterprises explore processing hazardous wastes on-site.
Pollutant kinds should be used to categorize waste streams. It's possible that this will identify incompatibilities that must be addressed before the waste streams can be mixed. Plating shops, for example, may generate both acidic and cyanide-laden waste streams, which are harmful to mix until the cyanide has been removed.
Categorizing wastestreams may also identify some that merely include conventional pollutants (e.g., BOD and suspended solids) and can therefore be released directly to a publicly owned treatment works (POTW) or a biological treatment plant without further treatment.
Domestic sewage vs. industrial effluent: Wastewater generation and treatment in India
Domestic wastewater is expected to be 22,900 million litres per day (MLD) in metropolitan areas, compared to 13,500 MLD for industrial wastewater. Domestic wastewater treatment capacity is just 5,900 MLD, compared to 8,000 MLD for industrial wastewater. As a result, there is a significant treatment gap in domestic wastewater treatment.
Under the Ganga Action Plan and later the National River Action Plan, the Indian government is aiding local governments in establishing sewage treatment plants. Because the task is so large, treating all of the wastewater could take a long time.
The total cost of creating a treatment system for all home wastewater is expected to be roughly Rs. 7,560 crores.
The expense of operation and maintenance would be in addition to this. Similarly, roughly 5,500 MLD of industrial wastewater, primarily generated by small-scale enterprises, remains untreated. The installation of wastewater treatment systems in small-scale companies is a challenge because many of them are located in residential areas with limited space.
Furthermore, small-scale enterprises lack the necessary resources to set up treatment systems. Common effluent treatment plants are required for these sectors (CETPs).Several of these institutions have been set up across the country. The creation of CETPs is intended to significantly lower the pollution load in the country's aquatic resources.
