“…Regarding biodegradation of organic matter, about 90% of abatement was obtained. This result is close to that recorded in a similar study using solar distillation (Zarasvand Asadi et al, ). However, it is lower relative to the treated water sampled from the WWTP; the latter was estimated at 98.2%.…”

“…A close result was reached for total coliforms except in September where the rate decreased to 84.6% (Table ). The results obtained are more efficient in comparison with a similar study conducted by Zarasvand Asadi et al () where the coliform disinfection rate was estimated at 86.8%. The exception to this was in September where both disinfection rates were relatively similar.…”

“…However, the studies focused on reuse of nutrients contained in sewage for plant culture (Quasim Syed, ), the dewatering of wastewater sludge (Haralambopoulos et al, ), the treatment of olive mills (Potoglou et al, ) and the treatment of textile industry effluent (Velmurugan and Srithar, ). It is only since 2012 that this process has been experimented with for sanitary and urban wastewater treatment (Igoud et al, ; Zarasvand Asadi et al, ).…”

Solar wastewater treatment (SOWAT) was the subject of experiment between April and September using low cost and mastery equipment: ‘hot‐box’ stills. Using a separate still, treated wastewater (i.e. distillate) production was recorded between 2.4 and 6 l m−2 day−1. Treatment efficiency was comparable to the activated sludge treatment process. Biological oxygen demand (BOD) recorded between 86 and 90% of abatement. Raw wastewater turbidity was reduced by 99%, from 181 nephelometric turbidity units (NTU) to 1.6 NTU. The treatment also allowed wastewater disinfection. The inactivation of total coliforms, faecal coliforms and faecal streptococci was estimated at about 99%. SOWAT offers the advantage of grouping, in a separate piece of equipment, three steps of conventional wastewater treatment: (i) the pre‐treatment, (ii) the biological and (iii) disinfection treatments. Also, this sustainable treatment does not consume electricity and consequently does not emit greenhouse gases (GHGs). Used on a medium and large scale, SOWAT would be promising for safe wastewater reuse in agriculture. This could secure food production of poor and low‐income countries, especially those that are very sunny. Copyright © 2017 John Wiley & Sons, Ltd.

Access to drinking water and sanitation are among the goals adopted by the United Nations in its 2030 Agenda for Sustainable Development. However, in poor and low‐income countries, this goal has not yet been reached. This is caused by several lacks in the technological mastery of water and wastewater treatment processes, fresh water and sanitation networks, and, finally, financial resources. Increasing the success chances to reach this goal should not happen by copying centralized water and sanitation systems used in high‐income countries. Rather efforts need to be made towards energy‐efficient decentralized water and wastewater treatment facilities, using simple and sustainable low‐cost technologies. The present paper suggests solar wastewater treatment (SOWAT) as an easy decentralized and sustainable wastewater treatment. It combines three steps of conventional wastewater treatment (i.e., pretreatment, biological treatment, and disinfection) by using a single treatment step conducted in a single equipment: solar still. It is has been experimentally tested to treat saline, domestic, municipal, and industrial wastewaters. All obtained results have recorded significant removal of inorganic, organic, bacteriologic, and metallic pollution. For community and industrial use, a new design of a hybrid SOWAT micro‐plant proposes the integration of a pretreatment stage and a smart multi‐source heating system. It is decentralized because it is powered by solar energy, other renewable energies, recovered flared gas, or conventional energy. Its continuous operation during the decrease or absence of solar radiation, by night, is expected to increase its daily production from 255% to 1,500%.
