  • Quantification and characterization of greywater from schools

    Survey of schools of different education levels (primary, intermediate and secondary) in Kuwait showed an average greywater generation rate of 7.3 L/p/d and varied in the range of 2.9–16 l/p/d, reflecting the school level of education (i.e. student age). The highest rates were observed for primary schools while the lowest rates were observed in secondary schools where students are more mature ...

  • 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 ...

  • Removal of Microorganisms from Domestic Greywater Using a Recycling Vertical Flow Constructed Wetland (RVFCW)

    ABSTRACTThe reuse of greywater (GW) is an attractive addition to water management options. One of the major concerns limiting GW reuse is the possible presence of harmful microorganisms. In addition to total coliform organisms, enteric organisms (Salmonella, Shigella and poliovirus Type 1 Cryptosporidium, Giardia) and opportunistic pathogens ( Staphylococcus aureus and Pseudomonas aeruginosa) may ...

  • Balancing water demand reduction and rainfall runoff minimisation: modelling green roofs, rainwater harvesting and greywater reuse systems

    Recent years have seen a growing interest in more distributed approaches towards stormwater management, often integrated with other forms of distributed management of urban water such as water demand management technologies. This paper focuses on the role of green roofs (GR), rainwater harvesting (RWH) and greywater reuse and their integration at the building level. A number of models were ...

  • Presence of selected priority and personal care substances in an onsite bathroom greywater treatment facility

    In recent years, concerns about climate change and the inefficient use and ongoing pollution of water resources have increased the political motivation to encourage water recycling. This has led to the widespread introduction of water saving measures and to advances in the decentralised treatment and reuse of wastewater. In particular, the treatment and reuse of greywater has received attention, ...

  • Systems Modeling for the Planning of Greywater Management in New Housing Developments in the City of Ensenada, Baja California, Mexico

    ABSTRACTThe implementation of a greywater reuse scheme for new housing developments in Ensenada would achieve significant savings (up to 37%) in water consumption with the corresponding monetary savings in water supply and wastewater treatment. New housing facilities would have green areas irrigated with greywater which would represent ecological and aesthetical benefits to city. A more detailed ...
