  • Algae Problems

    Almost everywhere where water is being stored, algae problems may occur. When water is stagnant, has a high temperature or a high concentration of Nitrates and Phosphates, an algae bloom might occur, which can cause several problems. Blue-green algae growth can cause a foul odour to the water, a layer of scum on the surface and even pose a health risk. Green algae may colour the water green, look ...

  • Prevent biofouling and reduce fuel costs in sea chests, hulls and cooling basins

    Biofouling growth increases the drag on a hull which results in a ship that uses up to 40% more fuel and correspondingly produces 40% more CO2 emissions. The marine industry globally spends billions of dollars in addressing fouling, using a variety of protection methods such as coatings. LG Sonic, a Dutch algae and biofouling control solutions provider, has introduced an Industrial Line which ...
