  • Ecological Conditioning and Optimisation of a Once-Through Cooling Water System

    For the coming decade, Dow Benelux will need antifouling treatment for its cooling water system. Hypochlorite dosing is still considered to be the best available technology (BAT). This is based on proven effectiveness, large experience, moderate costs, opportunities to further optimise the chlorination procedure, and by the fact that in earlier studies low-level ...

  • Carbon nanotube composite membranes for small ‘designer’ water treatment systems

    Small water systems that serve fewer than a few thousand persons are often less safe and less sustainable than large drinking water systems due to lack of suitable technologies. This ongoing research aims to develop a novel water treatment technology for small communities. By layering structured, functional carbon nanotubes (CNT) onto low pressure membranes (LPMs), composite membranes were ...

  • Optimisation chlorination strategy cooling water system Verve Energy’s Cockburn and Kwinana power plants

    In 2006, Verve Energy had, through the asset management department of Kwinana Power Station, contracted KEMA for advice on their antifouling methodology for its cooling water system. This has been done by optimizing its chlorination procedure by means of implementation of the Pulse-Chlorination® principle. Onset for the project was the commissioning of station Cockburn Stage 1 (CKB Stage 1). ...

  • Less Chlorine for Korean Mussels

    Abstract “KHNP used to apply conhinuous chiorination as an antifouling regime in iheir cooiing water system. Deveiopment of a new regime based on KEMA’s Pulse-Chlorination principie enabied the company lo reduce its chiorine use considerabiy. This means iower energy consumplion and reduced environmentai impaci,” explains KEMA’s Harry Poiman. KEMA recentiy completed a project in South Korea for ...

  • Experimental study on magnetic induction property of solenoid coil used in cooling water treatment system

    Magnetic induction intensity is a critical factor to determine electromagnetic descaling effects. The current in a solenoid coil is an important parameter affecting the intensity of electromagnetic induction. In order to explore how winding pipe diameter, number of turns and frequency affect the current in the solenoid coil wrapped around the carbon steel pipes, the variation of the current ...

  • Pulse-Chlorination®, the Best Available Technique in Macrofouling Mitigation Using Chlorine

    In 1998, KEMA developed a new chlorination method called Pulse-Chlorination®. It enables optimal antifouling treatment with a minimum use of chlorine. This technology is based on the principle that in general mussels and clams have a re-covery period after exposure to chlorination before opening fully and restarting filtration. The method takes advantage of this recovery time by using short ...

  • Optimizing Reverse Osmosis Membrane Life case study

    Background An Independent District Heating and Cooling Facility used a municipal Lake Michigan water supply to operate a reverse osmosis system with three 200- gpm trains and was experiencing highpressure differentials and short runs between cleanings. The water had an SDI of 5–6 prior to the prefilters and an SDI of 3–4 after the prefilters. The system does not require ...

  • Response of mussel Brachidontes variabilis to chlorination

    Untitled Document Brachidontes variabilis is a common fouling mussel species in cooling water systems of tropical coastal power stations. However, there are hardly any data available ...

  • Manufacturer of Water Treatment Chemicals and Water Additives

    Water treatment is a process for treating sewage or modern wastewater and converting it into more acceptable form for a specific end-use. The end utilization of this treated water might be drinking, mechanical water supply, water system, waterway stream support, water diversion or numerous different uses, including being securely returned to nature. Water treatment expels ...

  • Future-oriented further developments: wastewater heat utilization plants with a return on investment (ROI) of 2 - 6 years

    Sewage is dirty and stinks. Out of sniffing distance – out of mind. Up until the 1980s sewage was taboo and not given the attention it deserves. One cold winter morning in 1988, 23 years ago, Urs Studer stopped beside a steaming manhole cover and wondered how such a source of heat could go untapped. Ever since he has been dedicating himself intensively to the recycling of sewage heat. At ...

  • Rag time in Kalamazoo - Case Study

    Overview The Kalamazoo Lake, Sewer and Water Authority (KLSWA) In Michigan, USA, had all they could handle and more with their aging, failing aspirators, persistent fouling and ragging, and what seemed like an endless cycle of maintenance and repairs. Challenge KLSWA was consistently experiencing failing floats, ruined motors, debris-clogged ...

  • Biofouling & Biomonitoring: Mussels help keep Mussels at Bay

  • Perforation of ABS pipes by boring bivalve Martesia striata: a case study

    Acrylonitrile butadiene styrene (ABS) pipes are considered to be immune for boring organisms. However, inspection of the o0shore cooling water conduits of Lumut combined cycle power plant, Malaysia show that ABS pipes may not necessarily be immune for wood boring pholads, Martesia striata. M. striata caused heavy damage by drilling holes in ABS pipes used (about 5 years) for transportation of ...


  • Long-Term Water Quality Monitoring Deployments with the Sea-Bird Hydrocat-Ep - Case Study

    The new Sea-Bird Scientific HydroCAT-EP incorporates a suite of physical and biogeochemical sensors into a single, robust instrument designed to maximize water quality parameters and give sustained accuracy. The instrument uses the same high quality Sea-Bird and WET Labs sensors found on their industry    leading    CTDs    and    ocean ...

  • Nature inspires a better way to block biofilms

    In many industries where equipment comes in contact with water, including those that rely on water treatment membranes, equipment fouling is a huge problem. Biofilm fouling occurs when living organisms — including bacteria, algae, and even mollusks — become attached to boat hulls, harbor structures, and other equipment. The resulting damage can be costly. Coatings and other chemical ...
