In this report, experimental investigation of waste water treatment by reverse osmosis to enable its reuse in cooling tower is presented. A polyamide spiral wound RO membrane followed by three filters as RO pretreatment (two activated carbon and one cartridge filter) and samples of Tehran refinery treated waste water have been used. The effect of operating conditions such as pressure differ...

The integration of onsite, decentralized, and satellite wastewater treatment systems into existing urban water infrastructure is an attractive option for recovering water and nutrients locally for multi-purpose reuse. To facilitate wastewater treatment and reuse, tailored to local needs, a hybrid membrane treatment process is proposed that couples sequencing batch reactors with a membrane biore...

Research is currently being conducted as part of the AQUAREC project, with the objective being the development and validation of design principles for water reuse systems. To achieve the project objective, simulation and optimisation software for integrated water reuse systems need to be developed. A water reuse system is likely to have many possible design options: type and degree of treatment...

The capture, treatment, and reuse of storm-water runoff are win–win propositions that can lead to improvements in both human water security and ecosystem health. Although not all treatment technologies facilitate the capture, treatment, and reuse of water, biofilters do. Biofilters are engineered analogues of natural systems that use low energy, natural processes to treat stormwater. Biofilter ...

As population and water demand increase, there is a growing need for alternative water supplies from water reuse and desalination systems. These systems are beneficial to water augmentation; however, there are concerns related to their carbon footprint. This study compiles the reported carbon footprint of these systems from existing literature, recognizes general trends of carbon footprint of w...

In many situations in various countries wastewater is simply too valuable to waste. The Mediterranean countries are characterized by a severe water imbalance, mainly in the summer months, especially those located in the North Africa and Middle East region. This imbalance in water demand versus supply is due mainly to the relatively and uneven distribution of precipitation, high temperatures, in...

Water is fundamental for the quality of both ecosystems and society, plays a key role energy food production, prerequisite sustainable development [...]
