“…At a pressure of 50 bar, a maximum concentration factor of 5 could be achieved, resulting in the following recoveries of nutrients in the retentate: 70% for ammonium, 73% for phosphate, and 71% for potassium. The energy consumption of reverse osmosis depends on operational and technical parameters and energy recovery systems can be installed in large-scale applications (Avlonitis et al, 2003).…”

a b s t r a c tWastewater often contains valuable resources (e.g. organic matter and nutrients). Different from conventional sanitation approaches, the ecological sanitation (Eco-San) system is based on the closure of material flow cycles to recover resources with minimized demands on other resources. The review comprehensively summarized the main components of the Eco-San system (user interface, collection and conveyance, storage and primary treatment, and reuse/disposal), the frequently-used evaluation methods, and the framework of evaluation index system. Some typical practical cases were discussed to demonstrate the managerial implications and popularize the applications of the Eco-San system. The results show that the Eco-San systems are beneficial to resource efficiency, agricultural use of the organic matters and nutrients, and energy recovery although some shortages exist (e.g. high cost, cultural constraints, and complex operation and management). The evaluation methods can help to identify the restriction factors, contributing factors and measures to improve the efficiency of the future Eco-San system. The setting, selection and quantification are three critical steps when using the evaluation indices to complete the evaluation process. This study not only provides the methods for both developing novel Eco-San systems (combinations of the components) and improving the Eco-San systems (evaluation of the combinations) to solve the wastewater problem in rural areas. Considering the challenges or limitations in the Eco-San research, the recommendations for future research may mainly focus on the combination of different components, methods for sustainability assessment, quantification of the evaluation index, and implementation of more real Eco-San cases.

“…The membranes are generally manufactured by interfacial polymerisation which physically anchors the active and support layers together through interlocking of the pore structures [8]. Current industry consensus suggests that the average lifespan of an RO membrane is between five and ten years, although this is highly dependent upon feed water quality and operating conditions [9,10].…”

“…The pressure exchanger was investigated using the theoretical and mathematical simulation of a desalination plant, and the results showed that the specific energy consumption per m 3 product water was reduced by about 35% compared with ERT [8]. Power consumption and membrane replacement in seawater RO desalination plants have also been investigated, and energy consumption was found from range 3.02 kW/m 3 to 9.38 kW/m 3 [9]. Thermal systems are traditionally analyzed using energy analysis.…”

This paper presents an exergy analysis of an actual two-pass (RO) desalination system with the seawater solution treated as a real mixture and not an ideal mixture. The actual 127 ton/h two pass RO desalination plant was modeled using IPSEpro software and validated against operating data. The results show that using the (ERT) and (PX) reduced the total power consumption of the SWRO desalination by about 30% and 50% respectively, whereas, the specific power consumption for the SWRO per m with (PX). In addition, the exergy efficiency of the RO desalination improved by 49% with ERT and 77% with PX and exergy destruction was reduced by 40% for (ERT) and 53% for (PX). The results also showed that, when the (ERT) and (PX) were not in use, accounted for 42% of the total exergy destruction. Whereas, when (ERT) and (PX) are in use, the rejected seawater account maximum is 0.64%. Moreover, the (PX) involved the smallest area and highest minimum separation work.
