Introduction to the course:
With increase in industrial activities to fulfill the basic needs, the freshwater demand is rising. As a consequence, wastewater generation is also likely to increase significantly. The situation in developing nations like India becomes more alarming due to the shortage of good quality water in surface and sub- surface sources. In a sustainable society, it is imperative to protect natural resources and the surrounding environment by adopting efficient wastewater treatment processes. In order to encourage industries for taking appropriate measures to reduce freshwater demand partly by recycling treated wastewater, the regulations for water abstraction and wastewater discharge are becoming more stringent. The wastewater streams generated from process industries are contaminated by a variety of toxic and non-biodegradable inorganic and/ or organic pollutants which often require advanced treatment processes to make wastewater suitable for recycling. The choice of treatment strategy largely depends upon wastewater characteristics and the desired quality of treated wastewater.
Hence, this short course is designed for professionals working in industries to provide insight into developments in effluent treatment for promoting recycling of wastewater. The lectures will cover conventional and advanced treatment processes for industrial effluents. Various resource recovery options from the treated wastewater will be discussed. Apart from this, management of hazardous waste from the industries will also be discussed.
