Summary: This paper reviews the latest developments in biochar-based column filtration systems for greywater treatment and identifies areas for further research. The technology has been widely used globally and has shown promising results in pollutant removal and non-potable water reuse. However, more research is needed on social perception, new feedstocks, assessment, and improvement.

Summary: This study found that in rural areas, using decentralized greywater treatment systems for reuse is not economically viable, as the investment and operating costs are not offset by water savings. Economic indicators for treating light greywater were less negative compared to treating a mixture of light greywater and dark greywater in the two evaluated scenarios (public schools).

Summary: Fresh water scarcity is a growing issue in urban and rural areas, leading to an increase in non-potable water reuse. This study examines the potential of an off-grid water purification system using a staircase wetland with terracotta pot plants as a filter for greywater. The results show that the filtered water meets all requirements for water reuse.

Summary: This paper discusses the critical roles of spacers in membrane fouling control and proposes enhancing their effectiveness by improving design and geometry. New spacer designs have been shown to reduce dead zones, improve local mixing and turbulence, and reduce biofouling propensity through coating with biocide agents.

Summary: The residential reuse of greywater as a strategy to address water security issues has gained attention, with cities like Santiago de Chile promoting laws to mandate the incorporation of necessary infrastructure in new buildings. The success of water savings is influenced by individual consumers' choice to use the parallel system, and predicting their behavior is challenging due to the lack of widespread implementation. This paper proposes a method to predict policy effectiveness and greywater reclaim benefits based on individual preferences.

Summary: This study evaluated the reliability improvement of on-site greywater reuse systems on water supply. The results showed that the supply reliability significantly improved when on-site greywater reuse systems supplemented existing water supply systems. The improvement in supply reliability increased with the increase in maximum usable reclaimed water, treatment efficiency, and pipeline roughness coefficient. However, the improvement decreased with the increase in system age and pipeline failure growth rate.

Summary: The present study aims to verify a novel purification method for raw biogas using water-swollen composite membranes. In two module configurations, we generated water-swollen polymer gel layers on thin-film composite membranes to separate methane from other biogas species. The carbon dioxide solubility, many times higher than methane, effectively rejected methane from the water-swollen membranes and resulted in high methane recovery ratio and low H2S concentration in the outlet stream.

Summary: This article reviews various products for rainwater harvesting and greywater treatment and reuse on laboratory, pre-commercialization scale, and commercialized products. A conceptual framework is proposed to facilitate decision making for suitable decentralized water reclamation solutions. Decentralized systems are crucial in reducing dependence on centralized water supply.

Summary: As biodiesel production increases, so does the amount of wastewater generated. Minimizing wastewater production is important for the environmental friendliness of biodiesel technology. This study successfully utilized flotation pre-treatment and membrane separation to treat and recycle wastewater, supporting the sustainability of biodiesel technology.

Summary: Non-potable reuse of greywater can be an effective alternative to freshwater consumption, aligning with the Sustainable Development Goals. A pilot plant incorporating horizontal flow constructed wetland and anaerobic filtration was built to treat greywater from a Venezuelan family, achieving significant reductions in microbiological contamination. However, additional disinfection treatment may be necessary for complete pathogen removal in order to safely reuse the greywater, especially for irrigation of edible crops.

Summary: Portable handwashing facilities help fight water-borne diseases by optimizing biochar filtration parameters to remove pollutants from handwashing wastewater. The study showed that under optimal conditions, the biochar filter effectively removed color, turbidity, phosphates, and E. coli, complying with international water quality standards. Applying this technology to portable handwashing facilities benefits communities in developing countries with limited handwashing infrastructure and access to water.

Summary: In this study, a composite chitosan/graphene oxide (CSGO) membrane was successfully fabricated for bathroom greywater (GW) treatment. The addition of hydrophilic graphene oxide into chitosan matrix significantly improved the water flux permeation and GW treatment efficiency of the CSGO membrane. These findings demonstrate the potential application of CSGO membrane in producing high-quality treated GW for non-potable purposes.
