SHT-5000G Seawater Electrolysis Sodium Hypochlorite Generator

SHT-5000G represents the pinnacle of on-site disinfection technology. It utilizes the natural chloride ions found in seawater to produce high-purity sodium hypochlorite (NaOCl) solution. This system delivers an effective chlorine concentration of 1500–2000 ppm, providing a reliable, cost-effective, and safe solution for marine growth prevention and also industrial water treatment.

Core Operational Concept

The SHT-5000G eliminates the need for transporting and storing hazardous chemicals. By applying a direct current to filtered seawater, the system triggers a precise electrochemical reaction. The final product—sodium hypochlorite—is a powerful oxidant that effectively eliminates bacteria, viruses, and marine organisms (such as mussels and algae) in cooling water systems or ballast water.

The Six Essential Modules

The SHT-5000G is a modular powerhouse. Each section works in harmony to ensure continuous chlorine production with minimal manual intervention.

1. Seawater Pre-treatment System

Everything starts with clean water. This module removes suspended solids, silt, and also marine debris that could damage the electrolytic cells.

Seawater Lift Pump: This is the heart of the intake. It provides the necessary hydraulic pressure to move raw seawater through the entire system at the same time.

Self-cleaning Filter: This unit captures large particles. It features an automatic backwash function, which means the filter cleans itself without stopping the flow at the same time.

Flow Control Unit: Precision is key. We use electromagnetic flowmeters and regulating valves to maintain a steady flow rate. This ensures the output concentration remains consistent at the same time.

2. The Electrolysis Core (The System's Heart)

This is where the chemistry happens. The SHT-5000G uses advanced electrolysis technology to transform brine into disinfectant.

The Electrolyzer: We use a non-membrane, open-cell structure made from high-grade titanium. This design reduces maintenance and also increases durability.

The Electrodes: The anodes feature a Ruthenium-Iridium (Ru-Ir) coating. This rare-metal coating provides high electro-catalytic activity and also resists seawater corrosion. The cathodes are made of pure titanium for long-term stability.

Rectifier Transformer: This unit converts standard 380V AC power into low-voltage DC power. By adjusting the current, and also the PLC can precisely control the amount of chlorine produced.

3. Degassing and Storage System

Electrolysis produces a small amount of hydrogen gas as a byproduct. Safety is our priority, so we manage this byproduct strictly.

Degassing Tank: It utilizes the low density of hydrogen to separate gas from the liquid.

Blower System: A dedicated fan dilutes the separated hydrogen to a concentration below 0.5% (well below the explosive limit) before venting it safely into the atmosphere.

PE Storage Tank: The finished sodium hypochlorite sits in a corrosion-resistant Polyethylene (PE) tank. Integrated level sensors prevent dry running or overflows.

4. Acid Washing & Regeneration System

Over time, calcium and magnesium ions in seawater form scale on the cathode. This module restores the system’s efficiency.

Acid Tank: It stores a diluted citric acid or hydrochloric acid solution.

Acid Pump: When the PLC detects a rise in cell voltage, the pump circulates the acid through the electrolyzer. This dissolves the scale and restores the electrodes to “like-new” condition, significantly reducing energy consumption.

5. Electrical and Control System

The SHT-5000G is designed for “set and forget” operation.

PLC Logic: The Siemens-based PLC collects real-time data on flow, current, voltage, and also tank levels.

Safety Interlocks: The system includes multiple layers of protection. If the flow drops too low or hydrogen levels rise, the system shuts down instantly and triggers an alarm.

User Interface: Operators can monitor all parameters and also adjust settings via an intuitive HMI touchscreen.

6. Chemical Dosing System

The final stage delivers the disinfectant exactly where it is needed.

Dosing Pumps: We use high-precision metering pumps. You can set the exact dosage required to achieve the desired residual chlorine level in your target water.

Corrosion-Resistant Piping: All delivery lines use UPVC or PVDF materials to ensure the system lasts for years in a harsh marine environment at the same time.
