  • Innovative seawater intake for reverse osmosis desalination plants

    Seawater desalination plants typically consist of four major unit operations: seawater intake, pretreatment, Reverse Osmosis (RO) stage, and posttreatment and brine discharge. The best way is to go through vertical beach wells, but the increase of the production capacity of the plants built in recent years makes open intake the only solution. These open ocean intakes draw seawater through the ...

  • Nuclear power plant keeps intakes clean - case study

    When this nuclear power plant in the Great Lakes region needed reliable traveling water screens to keep it’s intakes clean, they chose International Water Screens. Vertical screens with hoods provide clean water to create steam to generate up to 725,000 kilowatts of electricity for the surrounding region. This project included: Traveling Screen(s) Elevator ...

  • Evaluating the relevance of seasonal differentiation of human health intake fractions in life cycle assessment

    The intake fraction (iF) is the fraction of an emitted mass of chemical that is ultimately taken in by an entire population and it is used as an indicator of human health potential impacts related to environmental chemical persistence and bioaccumulation in the food chain. In chemical screening applications, the iF can be predicted using multimedia and multipathway fate and exposure models. One ...

  • Effective Removal of Zebra Mussels with Amiad Screen Technology

    Introduction The zebra mussel, native to the Black and Caspian Seas, has spread in the past few decades to waterways throughout the world mostly via ballast water. Zebra mussels, when non-indigenous to the environment, pose a serious threat to intakes of facilities that rely on fresh and brackish surface water. The mussel colonies obstruct the flow of water through the pipelines eventually ...

  • PKU and MSUD screening for phenylketonuria and maple syrup urine disease

    Phenylketonuria (PKU) and Maple syrup urine disease (MSUD), branched-chain ketoaciduria are genetically transmitted metabolic diseases. PKU results in elevated Phenylalanine levels due to deficient activity of the enzyme Phenylalanine hydroxylase. In the MSUD state, elevated levels of leucine (Leu), isoleucine (Ile), valine (Val), and alloiso-leucine can be detected in blood. The increased ...

  • Methodology for conducting screening-level ecological risk assessments for hazardous waste sites. Part III: exposure and effects assessment

    The Idaho National Engineering and Environmental Laboratory (INEEL) has implemented a phased approach to ecological risk assessment (ERA). The first step in this process is a screening-level ERA at each facility. Basic to this approach was the development of ecologically based screening levels (EBSLs), defined as concentrations of chemicals in soil (or other media) that are not expected to ...

  • Mono nov completes major upgrade at knapp mill WTW

    Mono Pumps’ responsibilities included full risk assessment, temporary access and walkways, safety fencing to enclose the site from the public pathway, and craneage access. Mono co-ordinated all mechanical and electrical works, removing the old drum screens and installing six Mono L Series Discreens to the main and lagoon intakes atthe water treatment works. The Discreen was chosen by the customer ...

  • Devolping Pre-treatment Strategy for SWRO Systems

    Typically open-sea water intake structures are constructed in the shallow areas where sea water depth is in the range of 3m up to 10m. Due to this SWRO plant with open intake will have source water with high debris, suspended solids and aquatic organisms requiring a very elaborate pretreatment system. Thus Pretreatment design becomes an important part for a long term operation of the seawater ...

  • Peach Processing Wastewater Treatment

    A major fresh pack operation of peaches and nectarines needed a screening system to remove the labels and peach fuzz from their wash water before it was pumped from the pond for irrigation use. Flow to the pond is a steady flow of 50 gpm, rising to 600 gpm during periodic draining of the peach coolers and washing systems. The water is a combination of wash water, labels and fuzz from the fruit, ...

  • Dunstable sewage treatment plant steps up to mono nov for a complete extraction package

    Underlining its ability to supply either individual products or complete packaged systems for this type of application, Mono also provided two screw extractor systems and a single screw conveyor to partner an existingunit. The original step screen units installed on the Dunstable plant’s inlet flow had proved to be inefficient and unreliable. The replacement Discreen units now screen the inflow, ...

  • A mono nov discreen saves migratory fish

    Implementation of conventional filters at the plant, which serves the Preston area with 6.6 million gallons of water per day, was judged impractical as they would have required regular maintenance to clear leaves and debris,whilst conventional screening technology would have been prohibitively expensive and difficult to install at this particular site. Consulting engineers were initially called ...

  • Building a filter defense against Zebra and Quagga mussles

    Tiny mussels can create massive problems for intake structures, vaLves, pumps, screens and other water infrastructure around the US. Some filtration systems can provide chemical-free protection against invasive zebra and quagga mussels, but it is vital to understand the problem and develop the right system to avoid being overrun by the alien species. Zebra mussels (Dreissena polymorpha) and their ...

  • Invasion of the non-indigenous nuisance mussel, Limnoperna fortunei, into water supply facilities in Japan

    ABSTRACTThe aquatic nuisance mussel, Limnoperna fortunei, arrived in Japan before 1987 possibly with the Asian clam imported as food from mainland China. Now the mussel’s distribution has spread to two river systems in central Japan. Water authorities reported several cases of damage caused by L. fortunei. Most cases of damage were caused by dead mussels clogging small diameter pipes for raw ...

  • Exposure and food web transfer of pharmaceuticals in ospreys (Pandion haliaetus): Predctive model and empirical data

    The osprey (Pandion haliaetus) is a well‐known sentinel of environmental contamination, yet no studies have traced pharmaceuticals through the water‐fish‐osprey food web. A screening‐level exposure assessment was used to evaluate the bioaccumulation potential of 113 pharmaceuticals and metabolites, and an artificial sweetener in this food web. Hypothetical concentrations in water reflecting ...

  • A method for reducing purge volumes in deep monitoring wells: a purging experiment.

    Regulatory agencies often require three well casing volumes or more be purged prior to collection of groundwater samples for chemical analysis. Costs are high for testing and disposing of potentially hazardous purge water; therefore, efforts must be made to minimize waste-water volume while obtaining representative groundwater samples. Lockheed sponsored a purge experiment on two deep monitor ...
