  • New approaches for monitoring the marine environment: the case of antifouling paints

    Protection of ships hulls against biofouling has been a problem since man began sailing the seas. The most common protections are specially produced antifouling paints. These paints could be broadly classified in three main groups, or generations, depending on the technology applied: first generation copper-based, second generation organotin-based, and the new, third generation, organotin-free ...

  • Antifouling System Reduces Algal and Biological Growth on the In-Situ TROLL 9500 Water Quality Instrument

    Abstract New regulations regarding clean water have increased the need for long-term environmental monitoring. As water quality sensor technology improves and becomes more stable, the limiting factor in these projects becomes biological and non-biological fouling of instrumentation. Biofouling of environmental equipment increases site visits and maintenance, which elevate monitoring costs. ...

  • 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 ...

  • Tabas coal preparation plant wastewater treatment with membrane technology

    The goal of the present work is the Tabas coal preparation plant wastewater treatment using membrane technology. Polyacrylonitrile membrane was prepared through phase inversion method and then developed by annealing process. Also, high fouling resistance membranes were prepared by the embedding of TiO2 nanoparticles using self-assembling and blending methods. The effect of immersion time and ...

  • Investigation of surface and filtration properties of TiO2 coated ultrafiltration polyacrylonitrile membranes

    In the present work, the surface and filtration properties of TiO2 coated polyacrylonitrile ultrafiltration membranes were investigated. The membranes were coated using the physical deposition method. The appropriate TiO2 coverage proved to be 0.3 mg/cm2, which formed a hydrophilic cake layer on the membrane surface. The cleanability without chemicals and the retention of the ...

  • Surface Decontamination of Copper Compounds (Copper (elemental), Copper (I) Oxide) by DeconGel 1101

    Abstract Surface decontamination efficacy determination of DeconGel 1101 on stainless steel, carbon steel, concrete, Lexan, and rubber surfaces contaminated with elemental copper and copper (I) oxide (Cu2O) was performed with ICP-OES (Inductively Coupled Plasma-Optical Emission Spectroscopy) according to Environmental Protection Agency (EPA) SW-846 Methods: 3005A (sampling) and 6010C ...

  • 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 ...
