  • Soil Flushing

    Introduction In situ soil flushing is the extraction of contaminants from the soil with water or other suitable aqueous solutions. Soil flushing is accomplished by passing the extraction fluid through in-place soils using an injection or infiltration process. Extraction fluids must be recovered from the underlying aquifer and, when possible, they are recycled. Cosolvent Enhancement Cosolvent ...

  • Effect of first flush on storage-reliability-yield of rainwater harvesting

    Rainwater harvesting (RWH) entails capture of rainwater falling on a roof and conveyance to a storage tank for later use as domestic water supply. During dry weather, dust and pollutants accumulate on the roof surface and are subsequently washed off with the ‘first flush’ at the beginning of the next rain. Diverting the first flush can improve the quality of stored water but at the cost of ...

  • The Economic Argument for Flushing Optimization, and How ATP Monitoring Can Help

    As a way of controlling fouling in water distribution lines, utilities often conduct system-wide flushing cycles to clear lines of sediment, biofilm, and other accumulated material to maintain good water quality for customers. This can be done on an annual basis or as dictated by water technicians if more frequent flushing is needed. Take the city of Parker, Colorado (Population = 46,363) as an ...

  • Steel mill saves 200,000 € in closed circuit treatment with Cetamine technology - Case Study

    1. Background One of the largest integrated iron and steel factory in Mediterranean Region established a new blast furnace with a capacity of 2500 m3 and casting capacity of 8500 tons/day. The plant requested a proposal for the flushing of the new closed circuit system with a total volume of 1500 m3.The challenge was the blow down management during the flushing operation as it ...

  • How To Prolong The Life Of Your Boiler

    Regularly boiler maintenance will prolong the life of your boiler and improve efficiency, saving you money. Over the years sludge can build up within the system making it work harder, causing it to be inefficient and expensive to keep. A planned maintenance will flush the system, removing the sludge and other deposits, your gas engineer will also treat the boiler. Flushing a new system will also ...

  • The application of improved flow diverter for first flush management

    The paper presents the investigations on first flush phenomenon based on the total suspended solids (TSS) concentration measurement during selected rainfalls at central part of Czestochowa (Poland) and also the hydrodynamic model of the catchment. The model allows to present the conception of first flush management using an improved flow diverter Septurn. Flow diverters used in the separate sewer ...

  • Washoff behavior of in-sewer deposit in combined sewer system through artificial flushing experiment

    In-sewer deposits in combined sewer systems (CSSs) are closely related with the behavior of first foul flush and combined sewer overflows. However, the research paying attention to the role of in-sewer deposits is quite rare, furthermore, their contributions for the washoff patterns of each pollutant including pathogenic microorganisms are almost never discussed so far. The artificial flushing ...

  • Three years of operation of the urine diversion system at GTZ headquarters in Germany: user opinions and maintenance challenges

    In the main office building of GTZ in Eschborn, Germany a resource-oriented sanitation system containing urine diversion (UD) toilets and waterless urinals has been in operation since 2006. After 2.5 years of operating the system, a first overall evaluation of the system in terms of its acceptance amongst the users and the cleaning staff was conducted by carrying out two surveys and many ...

  • Imperial Wharf Incorporates Aquaco`s aquawiser system

    Imperial Wharf - Housing Association The Aquawiser system has been incorporated into this Housing Association new build at Imperial Wharf. The Aquawiser is a simple but effective way to recycle your grey water (bath and shower) for toilet flushing only. With the water consumption being slightly higher for bathing as it is to toilet flushing, there is enough grey water to ...

  • Control of urine odor in different sanitation practices and its implication on water saving

    To avoid odor in sanitation systems, urine is usually diluted with water (flushed), which leads to high water consumption. The smell may remain in sanitation systems if the systems are not well managed, or if the urine is flushed with insufficient amounts of water. In this study, using the standard threshold odor number (TON) measurement as an indicator of urine odor, the effects of the pH and ...

  • Real-time control of combined surface water quantity and quality: polder flushing

    In open water systems, keeping both water depths and water quality at specified values is critical for maintaining a ‘healthy’ water system. Many systems still require manual operation, at least for water quality management. When applying real-time control, both quantity and quality standards need to be met. In this paper, an artificial polder flushing case is studied. Model Predictive Control ...

  • High pressure pumping systems - it`s all in the design

    High pressure pumping systems are used in a wide range of industrial processes. Careful selection of the components of the pumping system is essential for optimum safety and reliability. Failure to install a quality pump designed for the task could present a potential risk to human health or life or result in significant down-time and loss of production capacity with the associated costs to the ...

  • Eco home in Brighton uses Greywater system

    Award winning eco home saves 100litres of water a day Having attended a self-build course, Jackie and Alan employed DRP, a firm of Brighton architects which produced a design that specified a whole range of eco technologies and materials including a grey water recycling system provided by Aquaco. Their new home achieved an 'Ecohomes' excellent standard thanks, in part, to water ...

  • Atoll Lagoon Flushing Forced by Waves

    Abstract Water level and current measurements from two virtually enclosed South Pacific atolls, Manihiki and Rakahanga, support a new lagoon flushing mechanism which is driven by waves and modulated by the ocean tide for virtually enclosed atolls. This is evident because the lagoon water level remains above the ocean at all tidal phases (i.e., ruling out tidal flushing) and because the ...

  • Adaptive control of algae detachment in regulated canal networks

    Open-channel distribution networks are subject to algal developments that can induce major disturbances such as clogging of hydraulic devices (pipes, weirs, filters, flow meters). Flushes can be used as a strategy to manage these algae developments. A flush is carried out by increasing the hydraulic shear conditions using hydraulic control structures of the canal network. In response to the ...
