  • Monitoring once through cooling water - Case study

    The Situation Power plants and paper mills use service water loops and mill water loops respectively for the cooling of lubricating, hydraulic, turbine and transformer oil.  These cooling systems feature large, recirculating volumes of water which are treated with biocides, dispersants, and corrosion inhibitors. By comparison, refineries often ...

  • 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. ...

  • Cornell Lake Source cooling cleaning - Case Study

    The project involved anchoring a sectional barge in 250′ of water on an inland lake, and recovering an intake screen weighing over 4 tons to the surface for cleaning and inspection. With the screen off, cleaning pigs (3) were sent through nearly 2 miles of 62″ diameter pipe to clean accumulated quagga and zebra mussels. ...

  • REMOVING LIMESCALE IMPROVES WATER QUALITY IN POULTRY FARMS

    Water is one of the most important nutrients in poultry production.  About 70 per cent of a bird’s body is made up of water - eggs contain around 65% water. Birds are constantly losing water in egg production, so there is an obvious need for constant replenishment.  Water intake is almost twice the weight of ...

  • 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 ...

  • Procedure for Determining the Segregation Potential of Freezing Soils

    Basic frost heave data obtained from various types of laboratory freezing tests, using computerized ramp temperature generation and temperature control at both warm and cold ends of a soil specimen, are analyzed to determine the segregation potential. Automatic volume change measurements provide fair values of cumulative water intake, but not accurate water intake rates. A method based on ...

  • 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 ...

  • Overview of seawater desalination status and challenges

    Introduction World oceans contain over 97.2% of the planet’s water resources. Because of the high salinity of ocean water and the significant costs associated with seawater desalination most of the global water supply has traditionally come from fresh water sources – groundwater aquifers, rivers and lakes. Today, however, changing climate patterns combined with population ...

  • Industrial wastewater - who discharges what and who pays for the cleanup?

    Canada's renewable water supplies are being threatened by vast amounts of municipal and industrial waste being disposed of in rivers, lakes and other marine areas. Those industries largely responsible are not paying their share for the clean up according to Statistics Canada. The Industrial wastewater business is huge involving water costs of $1.7 billion and water treatment costs of $656 million ...
