Significant Reduction in Industral Pollution in Ganga: Environment Ministry
New Delhi: The Government has underlined that there has been a significant reduction in industrial pollution in River Ganga. The problem of black liquor discharge and spent wash has been largely controlled. According to the last assessment in 2012, the total waste water generation and its organic load in terms of Biochemical Oxygen Demand (BOD) from 764 Grossly Polluting Industries (GPI) was 501 MLD and 131 tonnes per day. Conservative estimates say that discharge from industries has been brought down by 125 MLD. It is estimated that the BOD load reduction resulting from units which have achieved ZLD norms in distillery and pulp & paper sectors, apart from those which are permanently closed, will be about 30 tonnes per day.
Addressing a press conference here today, Minister of State (Independent Charge) of Environment, Forest and Climate Change, Shri Prakash Javadekar, said that there has been substantial progress in installation of Online Continuous Effluent Monitoring Systems (OCEMS). Out of 764 Grossly Polluting Industries (GPI), 514 units have already installed Online Continuous Effluent Monitoring System (OCEMS), while 94 are in the process. However, the Minister said that closure orders have been issued to 150 remaining units that have not responded to installation of OCEMS. Responses of 6 other units are being examined. Steps are also being taken to establish connectivity of OCEMS with the Central Pollution Control Board (CPCB) server.
The Central Pollution Control Board had formulated an Action Plan for abatement of industrial pollution in Ganga main stem states, covering five key industrial sectors - sugar, paper and pulp, distillery, textile and tannery, with the twin objectives of reducing effluent generation and organic load. CPCB is directly monitoring the progress of implementation of Action Plans in sugar, paper and pulp, distillery, while progress in other two sectors is being facilitated by the Ministry of Water Resources, River Development & Ganga Rejuvenation.
CPCB carried out inspections of 130 industries since December last year to assess progress in implementation of Action Plans. The 130 industries included 48 pulp & paper, 54 sugar and 28 distilleries units. The inspections were specifically mandated to confirm the facts relating to conservation of water, reduction in waste water generation and pollution load. In the process of inspections, public opinion was also taken into consideration.
A BRIEF REPORT ON INSPECTIONS CONDUCTED BY CPCB IN END DECEMBER, 2015 AND EARLY JANUARY, 2016
The sector-wise findings of 130 industries verified by the inspection teams are as under:
1. DISTILLERIES - 28
• All the 28 units have achieved no industrial Discharge by adopting system of bio-composting/incineration.
• BOD reductions from 22 Tonnes per day (TPD) to 2 TPD has been observed.
• No distillery was observed to be disposing spent wash.
• Multiple effect evaporators have been installed in 11 units and the rest of 17 industries are in process of installation.
• There were 6 public complaints relating to odour problem and unauthorized discharge.
• Four units were closed on the days of visit.
2. PULP & PAPER - 48
• All the 8 (eight) agro based industries have stopped discharge of black liquor.
• 42 industries were found operating ETP systems and have upgraded ETP system from two stage treatment system to three stage treatment system.
• Reduction in fresh water consumption and effluent generation has been observed in the industries.
• Five industries have achieved ZLD.
• Effluent disposal has been brought down from 119 MLD (out of 201 MLD) to 61 MLD.
• BOD load reduced from 76 TPD to 25 TPD.
• Six industries were found not in operation during the visit.
• Adverse public opinion received in case of four industries and 02 have been closed by Uttarakhand State Board.
3. SUGAR INDUSTRIES - 54
1. All units have implemented Action Plan and brought down waste water discharge from 400 litres/ton of cane crushed to 200 litres/ton.
2. It has been observed that :
• 19 units have achieved reduction in water withdrawal and waste water generation.
• 48 units are utilizing treated effluents for irrigation.
• Out of 54, only 3 units were found to be partially operating ETP.
• 6 units are by-passing the effluent/or disposing into drains.
• Complaints were made by public with respect to eight units account of disposal of ash causing air pollution.
4. ON-LINE INSTALLATIONS
It has been observed that out of 130 industries, 94 industries have installed online effluent monitoring devices, 31 industries have placed the work orders and/or in the process of installation. The remaining 05 industries who have not acknowledged the directions of CPCB are ordered for closure.[/vc_column_text][/vc_column][/vc_row]
