Are there any special challenges in treating wastewater?
  • Nutrients- Phosphorus, nitrogen, and other chemical nutrients found in wastewater can damage lakes and rivers. These nutrients need to be changed into less harmful substances or removed before being released into the environment.
  • Toxic Chemicals- Sometimes wastewater contains hazardous chemicals from industry, pesticides, etc. Controlling these chemicals may require pretreatment of wastewater by industries and the use of advanced (tertiary) treatment methods at the wastewater treatment plant.
  • Water Infiltration- Water entering the treatment system through cracks or joints in sewer lines or storm drains places an extra burden on a facility.
  • Changes in Water Flow - The amount and kind of wastewater entering a treatment plant can change quickly. Plant operators must be ready to respond to these changing conditions.

Treated water quality will meet the specified norms of CPCB/MPCB for water reuse

Is any planning done for remediation of polluted river stretches?
Yes, MPCB has monitored these river stretches and identified the reasons river-wise. An Action Plans are being prepared for remediation and implementation thereof and is already in process, such as, Godavari / Krishna River Clean Up Projects.
How does MPCB ensure that Municipalities are discharging their role about pollution control?

Sewage Treatment Plants and Solid Waste Disposal Facilities have to obtain the Consent/Authorization of the Board and the local bodies are mandated to run them according to the conditions laid down in Consent/Authorization, so as to comply with the Environmental Norms and to have less adverse effect on the environment.

Is it possible to prevent generation of waste by industries?

Yes. It is a question of using the right process technology and other measures for waste prevention mentioned above. With the advancement of new process technologies and raw materials, there is steady improvement towards prevention of generation of waste in some industrial sectors. These processes, however, have not reached such a stage that complete prevention of waste generation by all industries is possible.

What are the methods in practice for waste reduction, recycling and reuse?

Cleaner Technological options, ensuring mass balance, stochiometry and to improve the process with respect to yield, Reverse Osmosis, Distillation, solvent recovery, clarification, purification, use of waste as a raw material, waste exchange etc are some of the proven methods.

What are the important common waste treatment facilities in Maharashtra?

The common facilities in the State are CETPs (for effluent treatment), TSDF (for Hazardous Waste Disposal), Common incineration for incinerating certain kinds of waste, Common Bio-Medical Waste Treatment Facilities and Effluent Conveyance pipelines for transporting treated effluent to safer disposal points. The details are placed on the Website of the Maharashtra Pollution Control Board.

What are the parameters for which standards are prescribed?

Standards are prescribed for following parameters: Water : pH, Colour, BOD, COD, Total Dissolved Solids, Temperature, Suspended Solids, Ammonical Nitrogen, Oil & Grease, Toxicants, Fluorides, Phenol, Cyanides, Heavy Metals, Pesticides, Bacteriology, Fical Coliforms and Fluorides. Air : Suspended Particulate Matters, SOx, NOx, HCl, Cl2Ammonia, RSPM, etc
