Titanium anode for electrolytic disinfection in seawater aquaculture

A titanium anode for electrolytic disinfection in seawater aquaculture is a type of electrochemical electrode designed to generate oxidizing substances—such as chlorine, hypochlorous acid, and oxygen radicals—through the electrolysis of seawater. These oxidants effectively eliminate bacteria, viruses, and algae, providing a safe disinfection method without harmful chemical additives.

Key Functional Principle

During the electrolysis process, the titanium anode serves as the positive electrode. When a current is applied, chloride ions (Cl⁻) present in seawater are oxidized to form chlorine gas, which reacts with water to produce hypochlorous acid (HOCl)—a powerful disinfectant.
The reaction can be simplified as follows:

2Cl⁻ → Cl₂ → HOCl + H⁺ + Cl⁻

This electrolytic reaction ensures continuous disinfection of recirculating seawater in aquaculture tanks, pipelines, and filtration systems.

Technical Parameters and Performance Characteristics

These parameters can be tailored according to specific customer requirements and system configurations.​​​​​​​

Advantages of Using Titanium Anode for Electrolytic Disinfection in Seawater Aquaculture
1. High Disinfection Efficiency

Titanium anodes generate reactive oxidants efficiently, achieving rapid microbial inactivation and stable water quality.

2. Low Energy Consumption

The low chlorine evolution potential of the MMO coating minimizes power use during operation, reducing energy costs for aquaculture farms.

3. Safety and Automation

The system can be fully automated, eliminating the need for manual chemical dosing and improving safety for both operators and marine organisms.

4. Long-Term Cost Savings

While the initial investment may be higher, the long lifespan and low maintenance of titanium anodes lead to significant long-term savings.

Applications of Titanium Anode in Seawater Aquaculture
1. Fish and Shrimp Hatcheries

In aquaculture hatcheries, maintaining sterile conditions is vital for larval survival. Titanium anodes effectively disinfect intake seawater and recirculating systems, preventing the spread of pathogenic microorganisms such as Vibrio and Aeromonas.

2. Recirculating Aquaculture Systems (RAS)

Modern RAS facilities rely on continuous water reuse. The titanium anode for electrolytic disinfection in seawater aquaculture minimizes biofouling in pipelines and filtration units, ensuring stable water quality and reducing maintenance frequency.

3. Seawater Intake and Cooling Systems

In coastal aquaculture plants, seawater intake channels often suffer from biofilm and algae buildup. Installing titanium anodes in these systems provides continuous and automatic disinfection, extending equipment lifespan and improving operational efficiency.

4. Offshore Fish Farming Cages

For open-sea aquaculture cages, electrolytic disinfection systems powered by titanium anodes can help maintain water purity around cages and prevent disease outbreaks caused by bacterial blooms.

Real-World Case Studies
1: Seawater Shrimp Hatchery in Southeast Asia

A coastal shrimp hatchery implemented a titanium anode electrolytic disinfection system to treat intake seawater. The bacterial count decreased by 98%, resulting in a 20% increase in larval survival rate and a noticeable improvement in water clarity.

2: Offshore Fish Farming in Norway

In an offshore salmon farm, titanium anodes were used in a recirculating disinfection system to control algae growth. After six months, the system maintained consistent performance without electrode replacement, proving the durability of the MMO-coated titanium.

3: Seawater Cooling System in China

An industrial aquaculture plant integrated titanium anodes into its cooling and water supply lines. The electrolytic process prevented biofilm formation, reducing maintenance downtime by 40%.
