EICS - ECHLOR Electrochlorination System

FromEICS
SHARE
The ECHLOR Electrochlorination System by EICS Technology leverages the latest advancements in marine research and technology to effectively control marine growth within internal seawater systems. This system is designed to inject chlorine at the suction point, preventing the buildup of marine organisms. By utilizing electrolysis, the system generates chlorine from seawater itself, ensuring that pipelines and other components remain free from fouling. The process involves channeling a portion of seawater to a generating chamber where it is electrolyzed, producing chlorine, sodium hydroxide, and hydrogen. The chlorine-infused water is then injected into cooling systems to prevent organism adherence. Notably, the technology includes features such as compact size, reduced calcareous deposits, minimal maintenance, and explosion-proof solutions, making it highly efficient and reliable for marine applications. Additionally, EICS Technology utilizes Magneto special anodes to enhance system quality and durability, ensuring long-lasting protection and minimal environmental impact.

Using the latest advancement in marine research and technology, the Electrochlorination / Hypochlorination System was designed to prevent the marine growth from built up internal seawater system by injecting the chlorine to suction point. Using electrolysis, this intelligent, self-sufficient system is able to produce chlorine by breaking up the water molecule present in seawater itself, keeping your seawater pipeline system in peak condition always.

The process begins with some portion of seawater from seawater mainline system is channel to generating chamber to convert it to chlorine contain water, where the seawater is electrolysed and broken down by specialised electrodes into chlorine, sodium hydroxide and hydrogen. The product produce by generating chamber will discharge at suction point by via injection nozzle.

The chlorine infused seawater is then introduced into the seawater used to cool the various parts of the system that using seawater. The presence of chlorine deters marine organism from adhering and compounding itself in all parts of the system, including the sea chest, piping,heat exchanger and others.The process begins when the seawater from the ship’s pump is led to the Generating Chamber, where the seawater is electrolysed and broken down by specialised electrodes into chlorine, sodium hydroxide and hydrogen.

The process of electrochlorination is simple. It is the electrolysis of saltwater to produce a chlorinated solution. The first step is removing any solids from the saltwater. Next, the saltwater streams through an electrolyzer cell’s channel of decreasing thickness. One side of the channel is a cathode, the other is an anode. A low voltage DC current is applied, electrolysis happens producing sodium hypochlorite and hydrogen gas (H2). The solution travels to a tank that separates the hydrogen gas based on its low density. [1] Only water and ordinary salt, (sodium chloride (NaCl)) are used.

Companies may use seawater for this process due to its low cost. The water used is usually brackish water or brine (i.e. a solution with >0.5% salinity). In these cases, additional contaminant chemicals may be present in the water feed. The low voltage DC current still performs electrochlorination. The excess chemicals are left untouched and can be easily discarded.[2]

The product of the process, sodium hypochlorite, provides 0.7% to 1% chlorine. Anything below the concentration of 1% chlorine is considered a non-hazardous chemical[according to whom?] although still a very effective disinfectant. The sodium hypochlorite produced is in the range of pH 6-7.5, relatively neutral in regards to acidity or baseness. At that pH range, the sodium hypochlorite is relatively stable.[3]

 

The use of chlorine to counter Marine Growth is a well-researched and known subject. Tests have shown that 0.2 to 0.5 PPM of constant chlorination is able to keep all forms of marine fouling at bay.

While the larger marine shell organisms (e,g mussels) may attempt to protect themselves from the chlorinated water by shutting their shells and hiding themselves within, they will however be unable to feed in such an environment, hence depriving of the ability to settle themselves as deposits in the system interior.

Studies have also shown that any chlorination of a value higher than 0.5 PPM may induce corrosion of the system internal parts, such as the metallic piping, and other metallic Equipment. That being said, you need not worry about the corrosive aspect when deploying our Electrochlorination / Hypochlorite System as our system is endowed with the latest technology to sensitively and intelligently self-regulate the chlorination process accurately, ensuring your ship is constantly protected by all manners of marine fouling yet having none of the ill effects of chlorine corrosion.
