SEACLOR systems are the standard for power plants and desalination facilities, as well as coastal installations using seawater for cooling or other process needs all over the world. The extensive installation list as well as the reliable performance makes Seaclor the preferred electro-chlorinator in the industry.
Seawater Electrochlorination Benefits
Efficient protection against the growth of organic fouling.
No side effects of commercial hypochlorite (such as the building up of hard deposits by reaction of excess alkalinity with the substances dissolved in the water).
No safety hazards associated with gas chlorine
Eliminates dependency on oustide suppliers
Reduces the heavy costs of purchased commercial products
Because this technology eliminates dependency upon outside suppliers and the heavy costs of purchased commercial products, it finds application in a broad spectrum of industrial facilities requiring disinfection of water systems. These applications include:
Power Generation Thermal power stations powered by either nuclear energy or fossil fuel located along the seacoast normally use seawater as a coolant in the steam condensers. These are typically once-through cooling water systems. By controlling the fouling of the steam condensers the efficiency of power generation can be significantly increased. For example, in a typical 250 MW coal-fired power plant an increase of 0.2 inches of mercury in condenser back pressure (due to fouling) can cost the utility as much as $250,000 annually in fuel and replacement power costs. Sodium hypochlorite is introduced into the seawater intake to the power station where it also prevents fouling of the mechanical equipment, such as the seawater circulating pumps, bar screens and drum screens of the power station.
Desalination Plants When seawater is evaporated to produce potable water through multiple flash distillation or the salt is removed from the seawater by means of reverse osmosis. The equipment must also have a method to prevent the fouling of equipment due to the growth of marine organisms. This is an ideal application for SEACLOR Systems that produce sodium hypochlorite from seawater.
Coastal Industry Chemical plants, refineries, LNG production facilities, steel mills and other coastal industries that use seawater as a coolant in heat exchangers, also use SEACLOR Systems to prevent fouling of the equipment. The marine growth that takes place when seawater is used as cooling water can be either micro-or macro-type fouling. Maintenance costs are lowered considerably by avoiding the dismantling and mechanical cleaning of the heat exchangers and other equipment which comes in contact with the seawater.
Wastewater Treatment Plants After treating sewage through primary, secondary or tertiary treatment methods or a combination of all three, the effluent from the plant requires further disinfection before discharging to the ocean. This is typically done in a contact chamber and with chlorine gas or a related compound such as sodium hypochlorite. If the sewage treatment plant is located on the seacoast, the sodium hypochlorite produced from the seawater with SEACLOR is cost effective and a much safer method for this application.
