MGPS & ICCP systems
Evoqua Water Technologies understands the importance of keeping a vessel at sea and on the move.
- Maintain high operational reliability of cooling and heating systems onboard, and avoid the cost of an unscheduled shutdown
- Increase the lifetime of an asset through effective protection of hulls
- Potentially increase fuel efficiency thus reducing costs associated with a voyage
K.C. Ltd. is the manufacturer of marine growth preventing system based on sacrificial anodes.
The fouling problem arises when barnacles, mussels and other lower forms of marine life as larvae enter pipework systems and settle on the internal surface of pipes where they rapidly grow and multiply. In the most extreme cases, complete seawater lines can become blocked, affecting the safety and operational capability of the ship. In other instances, the gradual restriction in the flow of seawater through cooling systems can impair engine efficiency, leading to increased fuel usage. K.C. system is based on the electrolytic principle and consist of copper, aluminium and ferrous anodes which are fed with an impressed electrical current from a control panel.
In operation, the copper anode produces ions which are transported by the seawater and carried into the pipework system and equipment beyond. In this way, the anti-fouling system gives complete protection to pipework, valves and condensers as well as vital firefighting equipment, refrigeration and air conditioning unit. If you have any further questions about the antifouling system or inquiries for spares, contact us.

TYPICAL CHLOROPAC® SYSTEM SHIPBOARD INSTALLATION
The Chloropac® sodium hypochlorite generating system is designed to prevent marine growth in the sea water piping, heat exchangers, sea chests and coolers. Thousands of systems have been installed and is the preferred method of ship owners and operators. Low level continuous hypo-chlorination has been shown to be more effective than other types of marine growth prevention systems.
Chloropac MGPS have been proven within the marine market for over 40 years, and can boast thousands of installations worldwide.
THE PROCESS
A small amount of sea water, 5,7m3/hr (25 GPM) is taken from a sea water line which remains constantly under pressure. The water passes – at high velocity – through the electrolytic cells where part of the salt is converted to sodium hypochlorite. This is then returned to the sea chest and mixes with the incoming sea water. The cooling water will now contain a trace residual sufficient to prevent the attachment and growth of marine organisms, thus keeping all circuits – from intake to discharge – free from fouling. Sea water circulating pumps can be interconnected with the Chloropac system to ensure the output of sodium hypochlorite generated is automatically adjusted to suit the flow rates on board.
COMPARISON TO OTHER METHODS OF MARINE GROWTH PREVENTION
| CHLOROPAC® SYSTEM
|
ALTERNATIVE
|
|
| 1 | With a low continuous dose of 0.5 ppm or less the Chloropac electrochlorination system is able to control Micro as well as Macro fouling organisms. Micro = Slime, algae and weed. Macro = Barnacles,mussels, clams, hydroids, etc. |
In comparison, manufacturers of copper ion-type systems suggest a dose rate of 1 ppb will be sufficient to control all marine growth. Experience has shown that a dose rate of ~20 ppb is required to control Macro fouling. Additionally, continuous dissolution of copper and aluminium is not effective against micro fouling.
|
| 2. | The Chloropac system utilises platinum on titanium electrolytic cells (anodes) to produce the sodium hypochlorite from sea water. Chloropac cells are warranted for five years. Although in most common conditions normal cell life is approximately seven years. |
Copper based systems use “sacrificial anodes” that dissolve rapidly and need to be replaced every 12-24 months at a very high cost. Thus ongoing the consumable and maintenance costs for the operator are lower with a Chloropac system. |
| 3. | Chloropac system controllers can be adjusted manually or automatically to control the amount of hypochlorite being produced depending on the demand. The overboard discharge can be controlled to zero or near zero residual. |
Copper anodes are dissolved continuously and thus copper is discharged overboard, adding heavy metal pollutants to the ocean.
|
| 4. | As the Sodium Hypochlorite is produced by using only the ambient sea water, no biocides or pre cursor chemicals are required to be stored on board the vessel. All produced Sodium Hypochlorite is also injected directly into the sea chests. This simplifies purchasing storage, handling and chemical logistics on board. |
Chemical injection systems require the purchase storage and handling of highly corrosive and toxic chemicals. This creates an additional potential storage and safety hazard on board.
