Concept, outcomes and applications

The proposed concept of SWINGS introduces integrated and optimized solution for WW reuse in different areas of India.

The project will reach well beyond the current state of the art by bringing about new combinations of AD and CW technologies with a goal of more efficient utilisation of treated WW for irrigation, public and private uses and other uses. By integrating the complementary technologies, the project aims to generate environmentally, economically and technically feasible schemes for WW management in tropical sites. The overall goal of the project is to reduce clean water scarcity by reusing treated WW in different Indian regions and minimizing energy demand by producing biogas in the anaerobic digesters.

Hence, the main concept of the present project is the definition of an easy-to-use, low cost and zero discharge technology to treat and reuse WW in rural areas of tropical regions. A DSS will help to the technology definition, while identification of barriers to use of modern techniques for pathogen monitoring in developing countries will bring these techniques closer to implementation in WW treatment.

 Outcomes

The outcomes of the project are two-fold: novel combined treatment technologies for WW and sustainable concepts for water reuse.

The novel combined treatment technologies will concentrate on three main areas: enhance AD and CW by combination, nutrient recovery by irrigation treated WW and produce safe water with low cost disinfection alternatives to conserve water bodies. The goal is to develop configurations with the possibility of near future commercialization. The participation of municipal WW treatment plants, SMEs and public departments as project stakeholders will help in ensuring the feasibility of the new technologies.

To get an integrated view on the whole scheme of water generation and management, technical, financial and environmental sustainability analysis of the most promising and feasible water management schemes with highest level of innovation will be implemented.

Applications

The solutions developed in the proposed project are targeted for sanitation of rural sites of tropical regions. Integral configuration will be used to reuse WW to different applications as toilet flushing, recreation, cleaning, irrigation in agriculture, aquaculture farm feed and to safeguard the local drinking water supply in India.

Therefore, the developed processes and concepts will be suitable for mitigation safe water scarcity in those dry or arid sites of India and for energy saving (even to energy production) in those wet sites (using industrial waste of high organic concentration into anaerobic process).

The integral combination can be placed from household or neighbourhood community to decentralised areas of less than 10.000 equivalent habitants. On the other hand, factories which are interested in reusing or recycling their organic waste can be also end-user of the integral configuration developed in this project.
