A PPE electrolyzer for seawater electrochlorination is a specialized system that uses electrochemical reactions to generate chlorine from seawater, primarily for disinfection purposes in industries like marine engineering, desalination, and wastewater treatment.
Seawater electrochlorination relies on electrolysis to convert chloride ions (Cl⁻) in seawater into hypochlorous acid (HOCl) and hypochlorite ions (OCl⁻), which are powerful disinfectants. The process occurs in a PPE (polypropylene, polyethylene, or other corrosion-resistant plastic) electrolyzer, which houses the following key components:
Electrochemical Reaction
Anode (Oxidation): Chloride ions are oxidized to form chlorine gas:2Cl⁻ → Cl₂ + 2e⁻
The anode is typically an MMO (mixed metal oxide)-coated titanium electrode, chosen for its resistance to chloride corrosion and high electrochemical efficiency.
Cathode (Reduction): Water is reduced to produce hydrogen gas and hydroxide ions:2H₂O + 2e⁻ → H₂↑ + 2OH⁻
Subsequent Reactions: Chlorine gas dissolves in water to form hypochlorous acid and hypochlorite ions:
Cl₂ + H₂O → HOCl + H⁺ + Cl⁻HOCl → H⁺ + OCl⁻
The resulting HOCl and OCl⁻ effectively kill bacteria, algae, and other microorganisms.
Advantages of PPE Electrolyzers for Seawater Electrochlorination
Corrosion Resistance: PPE materials withstand the harsh, saline environment of seawater and the corrosive effects of chlorine, ensuring a long service life (10–15+ years).
On-Site Chlorine Generation: Eliminates the need to transport and store hazardous chlorine gas or chemicals, enhancing safety and reducing operational costs.
Energy Efficiency: Operates at low voltage (typically 3–6 V) and high current efficiency (>85%), minimizing power consumption.
Flexibility: Adapts to varying seawater salinities (20–40 ppt) and flow rates, making it suitable for different applications.
Environmental Friendliness: Produces chlorine in-situ with minimal by-products, reducing the risk of chemical spills or discharges.
Application
Marine Anti-Fouling: Preventing the growth of barnacles, algae, and mussels on ship hulls, offshore platforms, and intake pipes by injecting chlorinated seawater into the system.
Desalination Plants: Disinfecting seawater before reverse osmosis (RO) membranes to prevent biofouling, which can reduce membrane efficiency.
Industrial Cooling Systems: Treating seawater used in cooling towers to control microbial growth and scale formation.
Wastewater Treatment: Disinfecting effluent from marine-based wastewater plants before discharge.
Aquaculture: Sterilizing seawater in fish farms to prevent disease outbreaks among aquatic life.

Production
1. Substrate treatment: it needs to be treated by roughing, cleaning and removing oil, which can increase the compactness of catalytic.
2. Brushing coating:After substrate treatment, it will be proceeded brush coated. The main coated content is platinum group metal, which is a kind of mixed solution.Then, heat treatment will be going on after drying.The whole procedure need to be repeated many times. This method is better to form thin oxide catalytic that is lamellar adhere to substrate surface.
