  • Reduction of microbial risk associated with greywater by disinfection processes for irrigation

    Greywater is one of the most important alternative sources for irrigation in arid and semi-arid countries. However, the health risk associated with the microbial contents of these waters limits their utilization. Many techniques have been developed and used to generate a high microbiological quality of greywater. The main problem in the treatment of greywater lies in the nature of pathogenic ...

  • Opportunities and challenges for greywater treatment and reuse in Mongolia: lessons learnt from piloted systems

    In Mongolia, as worldwide, communities are challenged by water scarcity, depletion and pollution. Greywater treatment and reuse could partially meet water demand and help protect the environment and health. In March 2010, greywater from six randomly sampled households in the Ger areas of Ulaanbaatar, Mongolia, was analyzed followed by the development of three innovative treatment systems: an ...

  • Household greywater use practices in Melbourne, Australia

    Research on the potential of greywater reuse to reduce urban tap water demand has focused mainly on permanently installed greywater treatment or irrigation systems. These may be readily implemented in new housing developments, but experience in Australia shows their uptake by established households in urban areas is low. The majority of households employ simple and temporary methods for ...

  • Greywater treatment with biological aerated filter (BAF) for urban water reuse

    Greywater is an excellent resource for service water in intra-urban reuse. By substituting fresh water with appropriately treated greywater, it is possible to save 30–50% of fresh water. In this paper, an up-flow pilot biological aerated filter (BAF) is tested for the treatment of synthetic greywater and the design parameters are determined. An organic load of 8▒kg▒COD/(m3▒d) allows to achieving ...

  • Water cleaning and wetland construction

    Slippery Rock University's Macoskey Center for Sustainable Systems has served as an ideal locale for the study of biological waste and wastewater concerns in Western Pennsylvania. The Center's constructed ponds, waterless composting toilet and indoor greywater treatment system produced, in 19982000, great amounts of data on ecological approaches to wastewater treatment, which need to be reviewed. ...

  • Household greywater treatment methods using natural materials and their hybrid system

    Discharge of household greywater into water bodies can lead to an increase in contamination levels in terms of the reduction in dissolved oxygen resources and rapid bacterial growth. Therefore, the quality of greywater has to be improved before the disposal process. The present review aimed to present a hybrid treatment system for the greywater generated from households. The hybrid system ...

  • Greywater recycling system

    Every new home should have a Grey Water Recycling System! This innovative new product allows you to re-use your greywater (previously wasted) and recycle it for use on your gardens or reuse back through the toilets for flushing or in the laundry. Right now this is so important with low water levels, and water prices and council restrictions on the increase. The Ozzi Kleen GTS10 Greywater system's ...

  • Characteristics of greywater from different sources within households in a community in Durban, South Africa

    The reuse of greywater is steadily gaining importance in South Africa. Greywater contains pollutants that could have adverse effects on the environment and public health if the water is not treated before reuse. Successful implementation of any greywater treatment process depends largely on its characteristics in terms of the pollutant strength. This study investigated the physico-chemical ...

  • Greywater treatment by granular filtration system using volcanic tuff and gravel media

    The main objective of this study was to evaluate the efficiency of a granular filtration system (GFS) in greywater treatment under arid and semi-arid conditions. Six GFSs were designed, constructed, and monitored for approximately 13 months. Each GFS served a single rural Jordanian home by treating their greywater. Volcanic tuff media were used as the filtration media in three of the GFSs ...

  • Safe greywater reuse to augment water supply and provide sanitation in semi-arid areas of rural India

    Water reuse is recognized as a tool to increase water supply in peri-urban areas of semi-arid and arid regions of the world. However, it is an option rarely explored for rural areas in developing countries, and has not been documented extensively in the scientific literature. This paper presents results from 6 greywater reuse systems which were built with the objective to augment water supply and ...

  • Commercial wastewater treatment solutions

    Neatport PTY LTD, A.B.N. 62 063 770 534 is a registered company in Queensland, Australia, trading as Suncoast Waste Water Management (SWWM) which has been a registered business since 1983 manufacturing the ‘OZZI KLEEN’ range of wastewater treatment solutions for both domestic household, marine, and commercial applications. As the team behind the Ozzi Kleen product range, we strives to engineer, ...

  • Greywater reuse through a bioretention system prototype in the arid region

    The concept of a greywater-fed bioretention system in arid regions was investigated in this study. Bioretention systems are conventionally used as a source control mechanism for urban runoff. Nevertheless, in arid regions, where rain and urban runoff are not an abundant water resource, their application is limited. Greywater (residential wastewater without toilet and kitchen sources) is ...

  • Control of algal production in a high rate algal pond: investigation through batch and continuous experiments

    For decades, arid and semi-arid regions in Africa have faced issues related to water availability for drinking, irrigation and livestock purposes. To tackle these issues, a laboratory scale greywater treatment system based on high rate algal pond (HRAP) technology was investigated in order to guide the operation of the pilot plant implemented in the 2iE campus in Ouagadougou (Burkina Faso). ...

  • Greywater treatment in an aerobic SBR: sludge structure and kinetics

    In order to have an efficient operation, sequencing batch reactors (SBR) must support granular biomass with high conversion rates, settling properties, and be able to deal with the inherent variability of the composition of real wastewaters. In this study, the effect of the influent composition and the specific organic loading rate (Bx) on the granulation process was evaluated in two SBRs, ...

  • Green Village Delft – integration of an autarkic water supply in a local sustainable energy system

    For the Green Village at the campus of Delft University of Technology, an autarkic water circuit was developed. The aim was to avoid connections to the public water supply system, the sewerage, the electricity grid and cable systems. It should produce its own drinking water and electricity, and clean its organic waste streams in a sustainable way. Due to the strict Dutch drinking water ...

  • Reliability of on-site greywater treatment systems in Mediterranean and arid environments – a case study

    On-site greywater (GW) treatment and reuse is gaining popularity. However, a main point of concern is that inadequate treatment of such water may lead to negative environmental and health effects. Maintenance of single-family home GW systems is usually performed by home owners with limited professional support. Therefore, unless GW systems are reliable, environmental and public health might be ...
