The Water-Energy Regenerative House
Dr. Mohammad Ramezanianpour | Ara Institute of Canterbury | New Zealand
Future energy and water crises must be solved in a sustainable manner. This paper reflects utilisation of sustainable technologies in a regenerative house. A decision support system (DSS) is developed to address the water or energy sources to the demand points in a household. This project presents the importance of net-positive water and energy building in conserving our natural resources.
Improving water quality and pathogen removal using a low-cost anaerobic wastewater filtration –applicable for small-scale agricultural production in developing countries
Korbinian Kaetzl | Ruhr-Universität Bochum | Germany
Rice husk biochar, rice husks and sand as reference material were tested for their suitability for anaerobic wastewater filtration as low-cost decentralized water treatment approach on small-scale. The COD and the load of fecal indicator organisms could be significantly reduced. Thereby the performance of the biochar filters was significantly better than or equal to sand and rice husk filters.
Assessment of source separated sanitation technologies for sustainable wastewater management
Tayebeh Zinati Shoa | Technical University of Berlin | Germany
Source separated and conventional domestic sanitation systems are analyzed. A simulator of substance flow of all relevant processes is developed. The results show the feasibility of simulator to visualize different concepts of source separation and their comparison with conventional system which provide a better understanding of decision maker and urban planner.
High-integrate membrane bioreactor for wastewater treatment and reclamation in rural areas of China
Prof. Dr. Qiaoying Wang | Tongji university | China
In this study, we will present our industrialization achievement---High-integrate membrane bioreactor (HI-MBR) for both wastewater treatment and reclamation. The HI-MBR process includes the regulation tank, anoxic tank, aerobic MBR tank, membrane sludge thickening digestion (MSTD) tank and equipment room. The advantages of this product lie in the adoption of novel anti-fouling membrane materials, synchronous sludge thickening and digestion by flat-sheet membrane, unique phosphorus removal patent technology, professional design software, Internet of Things management technology, etc. Due to the above mentioned core technology, HI-MBR could obtain high quality effluent for reuse, such as flushing toilets, car washing and watering, etc. The membrane cleaning period could last for 6 to 12 months, and the occupy less than 1 m2/ton of water. On the basis of the use of Internet of Things management technology, the operation and maintenance of HI-MBR is much simple and efficient, and the labor cost is very low. The investment costs and operating costs of HI-MBR process are at the range of 450-1500 dollar/ton of water, consume 0.40-0.65 kWh/ton of water. HI-MBR process is suitable for rural decentralized domestic sewage treatment, villa domestic sewage treatment, river point source pollution treatment and other fields. Currently, we have built more than 200 wastewater treatment project with HI-MBR process in the Yangtze delta area. It is expected that the development and widely application of HI-MBR process could promote the treatment and reclamation of decentralized sewage in rural areas.
