Comparision of EC and Copper Ion

Electrochlorination or Copper Ion System

Biofouling is one of the main problems faced by every type of ship at the sea. Marine growth such as barnacles and mussels have been the reason for problems such as decreased ship efficiency, corrosion etc.

Biofouling not only sticks to the external surface of the ships but also gets into the water intakes and sticks to the surface of the pipes leading to problems such as blockage and corrosion.

Though mechanical removing tools can be used to get rid of such marine growth, this is not always possible. For this reason, different types of marine growth prevent systems are used on board ships, along with anti-fouling paints.

We will compare 2 main types of marine growth prevention systems available in the market

- Electrochlorination
- Copper Ion System / MGPS

DISTINCTIVE ADVANTAGES OF SEAWATER ELECTROCHLORINATION

Tested and proven performance to be the most effect against marine fouling
Utilizing the latest in marine research and technology, Electrochlorination/ Hypochlorination System has been designed to prevent marine growth from built up in internal seawater system by injecting the chlorine to suction point Using electrolysis, this Intelligent, self­sufficient system is able to produce chlorine by breaking up the water molecule present In seawater, keeping your seawater pipeline system in peak condition

Proven Results In Seawater Treatment

Chlorine(or Sodium Hypochlorite) proven to provide effect Anti Fouling Treatment against Fouling Organism

Proven Results In Seawater Treatment

Chlorine(or Sodium Hypochlorite) proven to provide effect Anti Fouling Treatment against Fouling Organism

Self Sustalnable

Chlorine is generated from Seawater, which is using an electrolysis process using Hypochlorite Generators installed.

Ease of Maintenance

Changing of Electro-chlorination cell is relatively light weight and does not require alot of manpower and equipment.

Longer Servlce Llfe

Electro-chlorination cell is able to last for 5-7 years during its service life.

DISADVANTAGES OF COPPER ION SYSTEM

Discharging of Copper into seawater, heavily regulated and Enviromentally unfriendly

Copper-Ion system Marine Growth Preventatlon system works by dissolving Copper into Seachest for every required flow llne that will prevent the accumulation of Bio fouling within the seawater cooling system. The system is connected to a power unit that will send a small current to the Anodes, resulting in a controlled release of ions to treat the seawater. Copper tolerance are among some marine Taxa (Including nuisance foulers and known invasion). resulting in adverse effect to long terms diversity within copper Impacted marine habitat

Copper is currently being subjected to an increase in global scurtiny as it could potentially be a marine pollut­ant and with the possiblity of ban extending into marine areas in the future.

Envlronmantally Unfrlendly

Dissolved Copper has an adverse effect on the diverse marine habitat in the sea.

Not Self Sustainable

Copper is dissolved into the flowline to treat seawater and will need to replaced once fully consumed .

Heavily Regulated discharge

Copper Anode Is heavy regulated by the Blocldal regulation (EU) 528/2012. All Copper must be pur­chased from a small number of sources. Failure to comply will be subjected to heavy fines.

Diffcult to Replace

As copper Is relatively much heavier that many other metals. Depending on the flow rate, with higher flow rate the copper will be sized heavier. Replacing of the anodes require heavy lifting equipment and manpower as some anodes are at least 150kgs each.

Poor Service Life

The system can only be design to a maximum of 5 Years.
