Environment Biological treatment best way to curb air, water and soil pollution: Experts Our Bureau
Thiruvananthapuram , Aug. 28 BIOLOGICAL treatment of waste water and waste air is the only cost-effective solution to pollution problems that the country faces, say experts attending the two-day national conference on biological treatment of waste water and waste air (BTWWA 2003) that got off to a start at the Regional Research Laboratory-Thiruvananthapuram (RRL-T) campus here on Thursday. BTWWA 2003 would seek to promote the quality of pollution control by finding new ways of enhancing biological treatment performance systems in the country's industrial sector. Inaugurating the conference, the Kerala Minister for Industries, Mr P.K. Kunhalikkutty, said developmental goals should seek to accommodate the concept of a pollution-free environment also. Dr T. Chakrabarti, Director Grade Scientist, National Environmental Engineering Research Institute (NEERI), Nagpur, delivered the keynote address. Dr B.C. Pai, Director, RRL-T, presided over. Dr G.D. Surender, Deputy Director and Head, Process Science and Engineering Division, RRL-T, and Mr Ajit Haridas, convener, BTWWA 2003, addressed the gathering. Efforts in vogue for controlling the release of pollutants such as waste water, solid wastes, odorous chemicals and volatile organic compounds have proved inadequate and do not conform to stringent standards and life quality. Ineffective waste abatement method is one of the main causes of the environmental problems being faced by the country. Biological treatment methods are among the most cost-effective solutions for control of water and soil pollution. In recent years, biological methods like gas bio-filtration have proved attractive options for treating waste air, removal of odour and volatile organic compounds. With its low maintenance and running costs, biological treatment has now become a major component of any waste water and solid waste management system. The new biological air treatment technology is also set to become the most prevalent in odour and volatile compound control applications. India's market for environmental technology and services is estimated at $2 billion but current expenditure does not add up to even half of this. The import of equipment for wastewater treatment and air pollution control has shown a negative trend indicating the growth of local environment control industry. Altogether, 45 scientific papers on diversified aspects of biological treatment of waste water and waste air are being presented at the conference organised to commemorate the silver jubilee year of the RRL-T and the diamond jubilee celebrations of the Council for Scientific and Industrial Research (CSIR). Experts from prestigious institutions such as IIT-Mumbai, IIT-Madras, University of Kerala, Vellore Institute of Technology, JNTU Hyderabad, Annamalai University, Bangalore Refinery and Petrochemicals, Kochi Refineries, Osmania University, the Kerala Co-operative Milk Marketing Federation, apart from RRL-T, are among those who are presenting papers.
