Activity for each output

Output 1: Development of institutional framework for research, development and promotion of water reuse technology
Water reuse technologies developed in this project are promoted and a guideline for research and development of such technologies in tropical regions in designed. "Research and Development Center for Water Reuse Technologies in Tropical Regions" is established at ERTC as a key institution for research, development and promotion of water reuse technology in tropical regions.

Output 2: Development of new energy-saving (or net energy-balanced) decentralized water reclamation and reuse system
A new energy-saving wastewater reuse system with organic waste recycling for high-rise buildings is developed. Incline-plate membrane bioreactor (iPMBR) is a critical technology to support energy saving in the wastewater reuse system.

This system can save costs by reduction of tap water consumption and contribute to society against global warming. This means that this project could provide a case of implementation of win-win water reuse system into which private companies can enter easily. Once this system is successfully developed, it could be widely employed not only in Thailand and other Southeast Asian countries but also in megacities around the world.

Output 3: Development of new water reuse technology with resource production (or GHG emission reduction)
We aim to develop water reuse technology which enables resource production or reduction of green-house gases by utilizing solar energy or solid waste. The developed technology is expected to be applied at places which lack alternative water resources to groundwater and other low-cost water supply.

For food industry, energy recovery by methane fermentation or resource production by photosynthetic microorganisms from concentrated organic wastewater is attempted in the process of water reclamation. This technology would realize water supply, energy recovery/resource production, and preservation of groundwater simultaneously.

For waste repository sites, utilization of biodegradable organic matters in solid waste is attempted in the process of water reclamation. This technology would realize reduction of green-house gases, such as methane, and supply of reclaimed water to neighboring area.

Output 4: Development of effective management and monitoring system for community-based water reuse
Considering new technologies developed in Outputs 2 and 3, an effective management and monitoring system to minimize risks in community-based water reuse is developed through the following studies.

(4-1) Development of water quality information platform
A platform to provide water quality information corresponding to its utilization purpose is designed and developed. Information required for the platform is collected.

(4-2) Model development to evaluate human health risks in water reuse
To realize a safe water reuse sustainably, method to monitor risk agents in reused water and model to evaluate the risks to human health are developed

(4-3) Evaluation and implementation of decentralized water circulation system
Issues in water circulation system in tropical regions are isolated and effects of water reuse technologies (e.g. iPMBR and pond/wetland system) on resolving the issues are evaluated.
