Wastewater Reuse and Recycling

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.

The presentation provides several water management measures including rainwater harvesting, grey water reuse, black water treatment and use and eco-sanitation in  Andaman and Nicobar islands. It also provides recommendations for modification in agricultural practices and other livelihoods that can be taken up with the given water availability.

The industry that currently does not treat or recycle any water. The treatment tank occupies less than 3 m2 floor area and the entire system costs less than Rs 1,00,000 to implement.

Specific processes include recycling/reuse of paper mill back water for dilution of bleached pulp and unbleached tower as well as for pulp slushing; of recausticising plant cooling and sealing water to clarifloculator; reduction in DM water consumption due to increase in process condensate recovery; arresting water piping leakages including fire hydrant piping by clamping; and recycling of paper machine primary clarifier outlet water for miscellaneous uses. Specific water consumption trends show a decrease from 183 cu m/tonne in 1997-'98 to 60.7 cu m/tonne in 2006-'07.
