Wastewater Reuse and Recycling

Specific methods used were automation of localized water storage system, elimination of water wastage by providing timer for water supply, constructing pond for harvesting rain water, optimisation of paint sludge pit cleaning, installation of screw compressors without cooling tower compressors, installation of spot cooling system, inst

The company has achieved this through recycle and reuse of wastewater, reducing water consumption by process changes, improving water efficiency in existing processes, implementing zero discharge effluent and reverse osmosis projects, reducing soft water consumption, eliminating water softener usage and using a new liquid surface conditioner.

 This has been carried out through strengthening its water monitoring system by installation of water meters at source points, recycling of effluent of reject pit discharge to abandoned mine pit, zero effluent discharge by providing sedimentation tanks and re-utilisation of effluent. Apart from water, work was also done on reducing Greenhouse gas emissions.

This work that included domestic waste-water recycling, reduction in river water usage, and by close circuiting of process water.won the 

It has achieved this through the use of dry low NOx burners, air cooled condensers, rainwater harvesting through building a pond, improving recovery in its reverse osmosis water treatment process and by increasing the cycle of concentration in its auxiliary cooling tower.

In this presentation Probhash Kumar Biswas and Tirthankar Sarkar of Jadavpur University, Kolkata have designed a rainwater harvesting and grey water recycling system to meet some of the water needs of the hostel block in Jadavpur University.

The Consortium for DEWATS Dissemination (CDD) Society is a not-for-profit organisation working in the field of decentralised basic need services across India. Decentralised solutions for wastewater treatment, water and energy supply, solid waste management and urban sanitation planning are successfully promoted for the past ten years.

CDD aims to create a knowledge base for up-scaling decentralised basic need services through its capacity building approach. CDD Society, in partnership with Bremen Overseas Research and Development Association (BORDA), Germany and Rajiv Gandhi Rural Housing Corporation Limited (RGRHCL) is organising a 6 days training programme on decentralised wastewater treatment systems (DEWATS) from 17^th August to 22^nd August, 2009 in Bangalore. The training aims to impart skills required for planning, implementing and managing DEWATS to the participants.
