  • 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 ...

  • Methods of Water Purification

    This article is excerpted from 'Pure Water Handbook' published by Osmonics®, Inc. of Minnetonka, Minnesota USA and is printed with permission of Osmonics, Inc. Water treatment can be defined as any procedure or method used to alter the chemical composition or natural 'behavior' of a water supply. Water supplies are classified as either surface water or groundwater. The majority of public or ...

  • Industrial cooling water fouling by Dreissenidae

    Together with the cooling water, a wide range of living organisms is entrained into cooling water systems, which can readily colonise the available surfaces in the system. Growth conditions in the cooling water system often are ideal for sessile organisms: the steady water flow assures abundance of nutrients and oxygen, while access for predators is limited. The consequence of this is that ...

  • Homeland Security for Drinking Water Supplies

    As it has done with other jurisdictions, Congress has recently passed legislation aimed at protecting our nation's drinking water resources. Historically, water supply protection has been a high priority, including reservoir protection, continuous monitoring, and secure and redundant facilities to ensure an uninterrupted supply of drinking water. The Clean Water Act (1972), requires pollution ...

  • 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 ...

  • Reclaimed Municipal or Industrial Wastewater for Power Plant Cooling & Boiler Feed Make-Up Water

    For centuries, water was considered a commodity product and used with little or no restriction. In today’s modern society, water is now being considered a precious resource and considerable effort is put into protecting, recycling, and restricting its use freely. State and Federal agencies have put in place guidelines and regulations restricting its use, especially for industrial use. ...

  • Remote controlled `Pit Hog™` dredge removing sludge from aeration lagoons at Los Alisos, California, Waste Water Treatment Plant

    The Los Alisos Water District Water Reclamation Plant is removing raw sewage solids, decayed algae and microorganisms, and algae-laden sludge from its aeration lagoons using a Liquid Waste Technology (LWT) remote controlled lagoon dredging system. The tertiary wastewater treatment plant treats four million gallons per day. Officials of the Lake Forest, California facility initiated the buildup ...

  • 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 ...

  • 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, ...

  • 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 ...

  • 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, ...

  • 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 ...

  • 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 ...

  • 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 ...
