Hotel Closer Notice from Pollution Control Board?
The water polluting industries which had not so far installed ETPs should be asked to furnish a time bound
programme to the Ministry of Environment and Forests for treatment of their effluents.
Those who have given commitment under Corporate Responsibility on Environment Protection (CREP) should
adhere to it.
Such programmes should clearly indicate the existing and proposed arrangements with detailed time schedules.
The programme should be backed up by a commitment from the Administrative Ministry concerned or the respective State Government, as the case may be, to provide the funds as necessary and ensure compliance by the industries.
If the undertakings and the administrative Ministry/State Government failed to respond, action under the Environment (Protection) Act needs to be taken forthwith thereafter.
SPCBs should monitor the progress and report on the outcome. The SPCBs should examine the prevailing arrangements in charging water supply for industry and formulate proposals in consultation with the concerned departments on how the system can be rationalized to conserve water and recycle it for use.
Emerging technologies such as aerobic composting, vermiculture, ferti-irrigation, etc. as secondary treatment should be adopted for the organic wastes by the industries. Recently, the root-zone technology is also being advocated is yet another alternative for energy saving for treatment of industrial wastewaters.
Incentives have to be made more attractive to make the industries undertake pollution control measures. It is important to assess the effectiveness of this measure and work out other measures which would serve as effective incentives for pollution control.
Reuse/recycling of treated industrial waste and resource recovery:
The reuse and recycling of wastes for the agricultural purpose would not only help to reduce the pollution and requirement of fresh water for such use but also would supplement the much-needed nutrients and organic manure to the plants.
The segregation of wastewater streams may help in reducing wastewater volume and waste strength and may help recycling and reuse of majority of waste streams. The quantity of the effluent generated in the sugar industry can be reduced from 300 litres to 50 litres per tonne of cane crushed if recycling techniques are meticulously followed.
The wastewater quantity generated in continuous fermentation distilleries is 7 litres per litre of alcohol produced, as compared to 14-15 litres per litre of alcohol produced in batch fermentation process distilleries.
The reduction in wastewater quantity is mainly achieved by recycling wash and adopting the reboiler system. In pulp and paper industries, the paper mill wastewater is completely recycled into pulp mill by adopting fibre recovery system. It has helped to reduce the wastewater from 200 cum to 50 cum per tonne of paper produced.
