  • Cooling Water Treatment in a Thermal Power Station

    Ozonia Switzerland and a water treatment company have successfullyinstalled and commissioned a turnkey, fully assembled, containerised ozone system in a large Thermal Power Station. The ozone produced by the plant will be used to treat the raw make-up water being fed to the cooling towers and to compliment the proprietary biocide dosing program being used in the cooling system at the ...

  • BioSense a Biofilm Monitor and Controller

    Abstract Biofilms (slime) can form on virtually every nonshedding surface, in a nonsterile aqueous environment i.e. anywhere where a water source is present; such as cooling/heating systems, swimming areas and in drinking water purification. These Biofilms can cause a myriad of problems including; harbouring harmful bacteria such as Legionella, inducing corrosion, and ...

  • RO Pretreatment Hydrocarbon Engineering - Optimisations of Osmosis

    Desalination by reverse osmosis (RO) is a fast growing technology, which is gaining more and more market share in the field of desalination applications. RO plants are able to produce extremely pure water with minimal impurities, even if they are charged with highly contaminated feed water. Based on the fact that the RO membranes themselves are able to separate the smallest ions out of the raw ...

  • Qatargas - Mantaining reliable and efficient operation of seawater cooling water systems

    INTRODUCTION To maintain a reliable and efficient operation of seawater cooling systems, a biocide must be added to prevent settlement and growth of marine fouling species, both macro- and microfouling. Worldwide, the typical industry practice in coastal areas includes continuous chlorination of the seawater with periodic shock dosing. However, this practice is not based on ...

  • An alternative cooling tower disinfectant: On-site generated mixed oxidants

    Favorable temperatures (80-110°F) and availability of nutrients make cooling tower systems ideal places for microbial growth. Accumulation of biofilm impedes proper heat transfer and secretes metabolic products that contribute to microbiologically influenced corrosion (MIC). The films also may propagate and release disease-causing bacteria. Control of microbial ...

  • Suitability of cationic flocculants for RO membranes performance improvement

    Abstract As it has already been published and demonstrated, one of the main causes of membranes failures is related to a poor plant pre-treatment. Data from more than 600 autopsies demonstrated that both biofilm and colloidal matter are the most common components on RO (reverse osmosis) membranes fouling, therefore, main lack on membranes pre-treatment is related to disinfection ...

  • Al Khafji SWRO plant - Case study

    Project FactsAdvanced Water Technology (AWT) build the Al Khafji Seawater Reverse Osmosis SWRO Desalination Plant, which is the world's first large-scale solar-powered desalination plant. It is located in Al Khafji to the north-eastern part of Saudi Arabia near the Kuwait border. The desalination plant was completed by late 2017. It will supply 60,000m³ of desalinated seawater a ...
