Treatment
The Ecochlor® Treatment System effectively eliminates aquatic species, bacteria and other pathogens from ballast water with proven ClO2 technology.
Low power and small footprint
Self-contained and fully automated
Designed for demanding marine use
Anti-corrosion coatings and materials for long life
No modifications to existing ballasting operations
Ecochlor’s Treatment System is a rugged skid mounted system that consists of the Chlorine dioxide (ClO2) Generator, self-contained chemical tanks, associated piping, valves and automated PLC controls.
The system is scaled for different sized ships. Because of the technical approach, larger systems are particularly cost competitive when compared to other technical approaches.
For system specifications, see table below.
A Scalable System
Ten times the capacity for less than twice the footprint
How it works
- The process generates a dilute solution of chlorine dioxide as it is needed to treat the incoming ballast water.
- The Generator operation is quite simple. When the system is off, there are no chemicals in the Generator. The only moving parts are the internals of the chemical pumps.
- When the Generator receives a start command from the ship's ballast water system, the supply water booster pump starts and a small amount of water flows through the Generator. The water can be seawater or fresh water and is only needed during ballasting. As water flows through a venturi, a vacuum is formed in the mixing chamber.
- Once the vacuum is formed, the chemical pumps start and meter precise amounts of Purate® and sulfuric acid into the mixing chamber. Pump rates are controlled by the PLC in proportion to the ballast water flow rate.
- As the Purate® and acid mix together in the mixing chamber, a chemical reaction takes place and ClO2 is formed. The ClO2 fills the mixing chamber.
- The ClO2 is drawn into the venturi by the vacuum created by the flow of water through the venturi. The ClO2 becomes an entrained gas in the supply water and this ClO2 solution is fed to the point of injection in the ballast water system.
