Electro Chlorination System
Electrochlorination systems generate chlorine-based solution from either delivered food-grade salt or seawater. In most cases, delivered salt systems are used where the water will be consumed. Seawater systems can be used to treat process water, cooling water, wastewater and other industrial water, such as fire water, at coastal locations where seawater is plentiful, or in offshore oil & gas operations.

Key Features of Electro Chlorination System
Reliability
Electrochlorination systems are reliable, providing a continuous and consistent chlorine production process.
Efficiency
The systems are designed with efficiency in mind, maximizing the conversion of salt to chlorine while minimizing energy consumption.
Versatility
From small-scale applications to large industrial processes, electrochlorination systems are adaptable to various settings.
Ease of Maintenance
Prioritizes user-friendly designs that streamline and simplify maintenance and minimize downtime.
Type of Electro Chlorination System
Brine Water Electrochlorination Systems
Designed for the production of Sodium Hypochlorite (NaOCl) from salt and water (brine), they are fully automated with PLC and touch screen controls. They can be used with either "softener" or "vacuum" salt (NaCl). Since the MA Series only requires salt, there are no safety, handling and transportation concerns that may arise when using chlorine gas or bulk sodium hypochlorite.
Sea Water Electrochlorination Systems
Producing sodium hypochlorite (NaOCI) from seawater. These high-load, high-performance electrolyzers use injection-molded PVC housings and bipolar electrode structures to intermittently generate sodium hypochlorite (NaClO) or hypochlorous acid (HClO) from seawater for disinfection or antifouling applications.
Applications of Electro Chlorination System
Municipal Water Treatment: Ensuring Safe Drinking Water for Our Communities
In municipal water treatment facilities, electrochlorination systems play a crucial role in making this a reality. These systems effectively eliminate pathogens, bacteria, and viruses, safeguarding public health. By generating chlorine on-site, municipalities can reduce reliance on hazardous chlorine gas transport and storage, enhancing operational safety and providing peace of mind to families.
Effluent Treatment: Protecting Our Environment
Industries produce a significant amount of effluent that needs to be treated before it can be safely released into the environment. Electrochlorination systems are used to treat industrial effluents, breaking down harmful chemicals and neutralizing pathogens. This application is critical for preventing pollution and protecting aquatic life, ensuring that the water returning to our rivers and oceans is safe.
Oil and Gas: Enhancing Operational Efficiency
Offshore oil and gas platforms face unique challenges in maintaining water quality. Electrochlorination systems are used to prevent biofouling in seawater cooling equipment, ensuring the efficient operation of vital equipment. These systems are favored for their reliability in harsh marine environments and their ability to operate continuously.
Power Generation: Ensuring Continuous Power Supply
Power plants require vast amounts of water for cooling purposes. Electrochlorination systems are used to treat this water, preventing the growth of algae and other microorganisms that can impede the efficiency of cooling equipment. This application is essential for maintaining optimal plant performance and extending the lifespan of cooling equipment.
Marine Industry: Ensuring Safe and Sustainable Operations
For ships, coastal communities, and remote areas, access to fresh water is often limited. Desalination plants are critical in converting seawater into potable water, with electrochlorination systems playing a vital role. These systems prevent the buildup of biofilms and contaminants in desalination membranes. This ensuring the continuous and efficient production of fresh water. Additionally, marine vessels rely on extensive cooling systems to maintain engine and equipment functionality.
How an Electro Chlorination System words
In an EC system, the water flow goes through an electrochlorination cell where water molecules and the salt in the seawater are decomposed according to the model H2O + NaCl + energy = NaClO + H2. The sodium hypochlorite molecule (NaClO) is the active ingredient that disinfects the ballast water and kills the microorganisms that have passed the initial filter. The electrochlorination cells, in turn, are powered by the rectifier.
Once the water has passed through the treatment system, the ballast water tanks are filled with the treated water – preventing any organisms from spreading into foreign waters. When de-ballasting, the Total Residual Oxidant (TRO) content is measured, and if it is too high, the ballast water is neutralized, e.g. by adding sodium bisulfite, so that no sodium hypochlorite is discharged into the sea.
The Process of Electrochlorination Systems
In the Electrochlorination (salt chlorination) process, common salt (Sodium Chloride) is converted to a low strength (0.5% to 0.8%) hypochlorous acid and sodium hypochlorite by electrolysis.
The process starts with streaming the saltwater through an electrolyzer channel (cathode and anode).
Next, a low voltage current is applied which leads to electrolysis that results in the production of sodium hypochlorite and hydrogen gas (H2).
This solution then travels to the tank, wherein the Sodium Hypochlorite is stored and dosed using dosing pumps.
The actual reactions are quite complex. However, the below equation represents the key Electrochlorination reaction:
NaCl + H2O + ENERGY → NaOCl + H2
