Overview of the Wastewater Treatment Business
Municipal and industrial wastes are primarily responsible for a wide variety of water contaminants(that can be both organic and inorganic). Inorganic compounds, in general, are generated from the leaching and weathering of soils, rocks and sediments. In addition, traces or small amounts of lead, copper, arsenic, iron and manganese may also be present. This makes the water very harmful to human consumption and the environment. Therefore, the institution of the Wastewater Treatment business must be promoted.
Market overview of Wastewater Treatment Business
According to the NITI Aayog, the market analysis of India’s Wastewater treatment business was worth 2.4 billion US Dollars in 2019. Further, it is projected to reach 4.3 billion US Dollars by 2025 due to increasing demand and awareness among people regarding sewage and its treatment business.
Fixed parameters set by the Government
Before proceeding with the wastewater treatment business, it is good to know some basic things. The Government, as per Central Pollution Control Board (CPCB), has set fixed parameters for wastewater within their limits: -
- For salt pans, shell fishing, mariculture and ecologically sensitive zone
Sr.No. |
Parameter |
Standard |
1 |
pH range |
6.5-8.5 |
2 |
Dissolved Oxygen |
5.0mg/l |
3 |
Colour and Odour |
Mainly caused by chemical compounds like creosols, phenols, naphthalene, pyridine, benzene, toluene etc., causing visible colouration of salt crystals and tainting of fish flesh. |
4 |
Floating Matters |
Surfactants should not exceed detrimental for use an upper limit of 1.0 mg/I and purpose. The concentration is not to cause any visible foam. |
5 |
Suspended Solids |
None from sewage |
6 |
Oil and Grease (including Petroleum products) |
0.1mg/l |
7 |
Heavy Metals: Values depend on: Mercury (as Hg) Lead (as Pb) Cadmium (as Cd) |
0.001mg/l 0.001mg/l 0.001mg/l |
- For industrial cooling, recreation (non-contact) and aesthetic
Sr.No. |
Parameter |
Standard |
1 |
pH range |
6.5-8.5 |
2 |
Dissolved Oxygen |
3.0 mg/l or 40 per cent saturation value, whichever is higher. |
3 |
Colour and Odour |
No noticeable colour or offensive odour |
4 |
Floating Matters |
No visible/obnoxious floating debris, oil slick, or scum. |
5 |
Faecal Coliform |
500/100 ml (MPN) |
6 |
Turbidity |
30 NTU |
7 |
Dissolved Iron |
0.5mg/l |
8 |
Dissolved Manganese |
0.5mg/l or less |
The range of parameters in wastewater as per 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.
- The arsenic limit should be a maximum of 0.2 mg/l.
- Ammoniacal Nitrogen should not be more than 50 mg/l.
Additional licenses
Apart from the certificates and authorisation for setting up a wastewater treatment plant mentioned above, additional licenses are also required. The list includes:-
- ISO certificate
- A raw water test report
- Chemists’ and microbiologist’s certificates
- Registration of trademark
- ISO 9001:2008 certificate
- If appropriate, a Gram Panchayat No Objection Certificate (NOC) is required, depending on the location of the plant
- Workers' medical certifications
- Documents about land ownership/lease to establish the plant to avoid future problems and land conflicts
- The plant's electrical load should be approved
- Plan for sanctioned layout
