 SEACLOR®
On-site Hypochlorite Generation from Seawater
Power, Desalination and Coastal Seawater Electrochlorination
SEACLOR® systems are the standard and preferred electrochlorination
unit for biofouling control in power plants, cooling towers, liquefied
natural gas (LNG) terminals and desalination facilities, as well as
coastal installations using seawater for cooling or other process
needs all over the world.
SEACLOR® for the on-site generation of hypochlorite from
seawater has demonstrated reliable, economic and low
maintenance operation in numerous installations throughout
the world SEACLOR® systems range in capacity from
500 to 50,000 lb/day (10 to 900kg/hr), per train.
Benefits of seawater electrochlorination:
- 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 outside 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.
System Requirements
Location of seawater intakes in waterways, harbors, estuaries or deltas frequently means that the seawater is contaminated; the same may occur near industrial or urban wastewater facilities.
Seawater containing high amounts of suspended organic material and oil may not be suitable for electrolysis. In certain cases, the seawater quality can be improved by special filtering/water treatment systems to make it suitable. Where possible alternative sources of seawater should be considered, e.g. by tapping salty aquiferous layers.
In each case, complete analysis or representative samples of seawater to be used should be sent to STDN to determine its suitability and/or the required treatment.
