Standard Brine Electrochlorination Systems for Water Treatment
Century designs and manufactures industrial-grade standard brine electrochlorination systems that provide a safe, economical, and highly effective method for on-site water disinfection. By utilizing only food-grade salt (sodium chloride), water, and electricity, our systems generate a robust 8,000-9,000 ppm sodium hypochlorite solution directly at your facility. This process completely eliminates the severe safety risks, rigid Process Safety Management (PSM) compliance, and high logistical costs associated with transporting and storing bulk liquid chlorine gas or commercial bleach. Engineered for heavy-duty municipal and commercial water treatment plants, our brine electrolysis equipment delivers continuous, reliable oxidation exactly when and where you need it.
Core Advantages of Century Brine Electrochlorination
Transitioning to an onsite chlorine generation system fundamentally optimizes your facility’s operations:
- Uncompromising Safety: Eliminate hazardous chemical leaks and the need for high-pressure storage vessels. Our systems operate safely, venting harmless trace hydrogen byproducts automatically.
- Drastic Cost Reduction: The operating expenditure (OPEX) of utilizing raw industrial salt and standard electrical power is significantly lower than purchasing manufactured chemical disinfectants.
- High-Efficiency Ru-Ir Anodes: At the heart of our systems are Century’s proprietary titanium anodes, coated with specialized Ruthenium-Iridium oxides. These plates guarantee extended lifespan and maintain over 85% electrolysis efficiency even under sub-optimal 1% brine concentrations.
- Consistent Chemical Potency: Commercial bleach degrades rapidly during transport and storage. On-site generation ensures you dose 100% fresh, highly reactive hypochlorite into your water stream every time.
System Component Breakdown (Features)
Unlike a general overview, our standard brine electrochlorination system is a meticulously engineered complete loop, featuring the following premium components:
- Automated Brine Make-Up: Water flows through a softener into a salt dissolver, creating a saturated (25%) brine, which is then precisely diluted to the optimal 3%-5% concentration for electrolysis.
- Electrolysis Cell Housing: Constructed from durable, corrosion-resistant profiles. The transparent housing allows for easy visual inspection of the titanium electrode stacks during the reaction: NaCl + H2O → NaClO + H2↑.
- Intelligent PLC Power Center: Features highly stable rectifiers (DC power) and an intuitive control panel. Options include single-button start protocols and automatic reverse-polarity functionality to drastically reduce calcium scaling and maintenance downtime .
- Dosing & Storage Unit: Safely stores the generated 8,000 ppm solution and utilizes precision magnetic circulation pumps and dosing valves to inject the exact required amount based on residual chlorine sensor feedback .

Industrial Applications
Century’s commercial electrochlorination plants are built strictly for B2B applications, keeping residential and small pool systems entirely separate. Our systems are currently deployed across the US, Spain, and Venezuela for:
- Municipal Water Treatment: Primary and secondary disinfection for large-scale drinking water utilities.
- Wastewater & Sewage: Neutralizing biological hazards in industrial effluent and municipal sewage before discharge.
- Cooling Towers: Suppressing algae and biofilm buildup in industrial thermal circulation water.
- Food & Beverage Processing: Sanitizing process water to meet strict FDA and USDA compliance without the taint of degraded commercial bleach.
Rigorous Factory QA & OEM Replacement Services
Every single system component—from the Ru-Ir titanium plates to the magnetic valves—undergoes a strict design review and a mandatory 72-hour continuous production test before it leaves our facility . If you have an existing commercial electrochlorination plant that requires an upgrade, our engineering team specializes in custom drop-in replacement cells and seamless retrofits. We provide competitive factory-direct pricing to ensure high cost-effectiveness for your procurement.
Frequently Asked Questions (FAQs)
The system requires standard industrial or food-grade sodium chloride (NaCl). High purity is recommended to maximize the lifespan of the titanium anodes and reduce cleaning frequency.
Absolutely. Our systems are designed specifically as safe, economical drop-in replacements for hazardous gas and bulk liquid chlorine infrastructures.
Thanks to our proprietary Ruthenium-Iridium coating, our anodes have an exceptional operational lifespan. Depending on usage and water hardness, they typically last 5 to 7 years. All systems come with a standard 2-year warranty.
