In ships, offshore oil platforms and power station, seawater is used to cool equipment and heat exchangers. In ships and platforms, in addition to sea water cooling systems, seawater is pumped into fresh water generator (FWG) to produce fresh water. Sea water, which has high sulfur, chloride and carbonate mineral and salts, is deposited over time in the exchangers. On the other hand, seawater has a lot of microorganisms that enter the cooling heat exchangers and find the temperature of about 30 to 35 degrees Celsius very suitable for the rapid growth. Bacteria and other microorganisms quickly grow on the surfaces of tubes and heat exchangers. The thermal resistance of 1 mm of biofilm is greater than a 1 mm of silica, so biofilm growth in seawater systems is a major factor in reducing the efficiency of heat transfers and also the heat exchangers. HydroFlow Marine descaler, by sending radio signals into water, forms clusters of hardness ions, and by increasing water temperature, these clusters turn into stable crystals which do not adhere to surfaces and attract other ions.
Also, radio signals stimulate the biofilms, and over time, the sticky layers of the biofilm are separated from the surfaces. Also bacteria and algae that pass through the HydroFlow Marine descaler receive a positive and negative charge at a frequency of 150,000 times per second, which causes a rapid change in the osmotic pressure of the bacteria and rupture the cytoplasm. HydroFlow Marine is a completely non-chemical device that removes limescale and kills bacteria without using anti-scale chemicals and biocide agents.
