  • Will greywater reuse really affect the sewer flow? Experience of a residential complex in Al Ain, UAE

    Reuse of recycled wastewater is one of the most feasible unconventional urban water sources in the United Arab Emirates (UAE). The extraction and reuse of greywater might affect the water and sewer pipe networks by changing flow characteristics. Therefore, the research question is how much greywater can be reused without affecting the existing water and sewer pipe networks? A residential ...

  • Wastewater treatment for mining camps/oil and gas camps

    Mining and oil and gas camps operating in remote and environmentally sensitive areas become home to large work forces for extended periods of time. Supplying water for domestic use and treating large volumes of sewage and greywater can be a complex and expensive challenge. Improper wastewater treatment can lead to pollution of the surrounding ecosystems. Many jurisdictions have tightened ...

  • An integrated system dynamics – cellular automata model for distributed water-infrastructure planning

    Modern distributed water-aware technologies (including, for example, greywater recycling and rainwater harvesting) enable water reuse at the scale of household or neighbourhood. Nevertheless, even though these technologies are, in some cases, economically advantageous, they have a significant handicap compared to the centralized urban water management options: it is not easy to estimate a ...

  • Membrane process treatment for greywater recycling: investigations on direct tubular nanofiltration

    On-site greywater recycling and reuse is one of the main ways to reduce potable water requirement in urban areas. Direct membrane filtration is a promising technology to recycle greywater on-site. This study aimed at selecting a tubular nanofiltration (NF) membrane and its operating conditions in order to treat and reuse greywater in buildings. To do so, a synthetic greywater (SGW) was ...

  • Estimated costs of implementation of membrane processes for on-site greywater recycling

    Greywater reuse inside buildings is a possible way to preserve water resources and face up to water scarcity. This study is focused on a technical-economic analysis of greywater treatment by a direct nanofiltration (NF) process or by a submerged membrane bioreactor (SMBR) for on-site recycling. The aim of this paper is to analyse the cost of recycled water for two different configurations (50 and ...

  • Impact of water source management practices in residential areas on sewer networks – a review

    Prolonged drought which has occurred everywhere around the world has caused water shortages, leading many countries to consider more sustainable practices, which are called source management practices (SMPs) to ensure water availability for the future. SMPs include the practices of water use reduction, potable water substitution and wastewater volume reduction such as water demand management, ...

  • Organic matter degradation in a greywater recycling system using a multistage moving bed biofilm reactor (MBBR)

    Greywater is an important non-conventional water resource which can be treated and recycled in buildings. A decentralized greywater recycling system for 223 inhabitants started operating in 2006 in Berlin, Germany. High load greywater undergoes advanced treatment in a multistage moving bed biofilm reactor (MBBR) followed by sand filtration and UV disinfection. The treated water is used safely ...
