Cloro Soda

Chlorine Alkali MMO electrode repairs

The Chlorine Alkali Industry has been implementing electrolytic production of chlorine and caustic soda from sodium chloride or potassium chloride solutions for a long time. At the heart of this process are dimensionally stable anodes, particularly titanium substrates coated with mixed metal oxides (MMO). These MMO-activated titanium anodes have been the industry standard for decades, valued for their durability, stability, and electrochemical efficiency. Their role is indispensable: they enable the controlled and sustained generation of chlorine gas at the anode, while sodium or potassium hydroxide forms at the cathode.

Chlorine produced in this way serves as the feedstock for an extraordinary range of downstream chemical products. In its elemental form, chlorine is widely applied in water treatment, disinfection, and industrial synthesis. However, through subsequent electrochemical conversion, it can be transformed into a family of valuable compounds including hypochlorite, chlorate, and perchlorate. Each of these products supports critical industries: hypochlorites are essential in sanitation and bleaching, chlorates are widely used in pulp and paper processing, and perchlorates have applications ranging from propellants to specialty oxidizers. Across all these pathways, the quality and efficiency of the anode surface determine not only production yields but also energy consumption and overall sustainability.

In this demanding field, the ability to provide reliable and high-performance anodes is fundamental. That is why our work goes far beyond supplying standard electrodes. We specialize in delivering tailored solutions designed to meet the unique operational requirements of each plant or process. Every client faces different challenges—variations in brine purity, cell design, operating current density, and local regulatory constraints. By collaborating closely with operators, we ensure that each anode is engineered for optimal compatibility and performance.

What we do for the Chlorine Alkali industry

Our portfolio includes the supply of custom-built MMO anodes, which can be fabricated in virtually any dimension, geometry, or coating formulation needed for a specific application. Whether the system requires anodes for membrane cells, diaphragm cells, or specialized electrochemical reactors, our team has the expertise to design and deliver electrodes that balance efficiency, durability, and cost-effectiveness.

Beyond new anodes, we also provide specialized re-coating services. Over time, the coating layer of MMO anodes may degrade due to wear and operating conditions, reducing current efficiency and risking contamination. Instead of replacing the entire electrode structure, our re-coating services restore the surface to like-new condition. This approach not only extends the service life of the titanium substrate but also significantly reduces costs and environmental impact. In the same vein, we offer regeneration services for exhausted anodes, carefully stripping, preparing, and recoating them to maximize reuse and minimize waste.

By combining material science, electrochemical expertise, and state-of-the-art laboratory capabilities, we ensure that every electrode we supply or refurbish meets the highest standards. Clients benefit from reduced downtime, lower operating costs, and consistent performance even under the harshest electrolysis conditions.

The impact of these solutions is far-reaching. Efficient and durable anodes directly translate into reduced energy consumption, a critical factor given the high electricity demands of chlor-alkali production. Longer-lasting coatings mean fewer disruptions and lower maintenance costs, while the ability to regenerate anodes supports sustainability goals and responsible resource management.

For more than a generation, MMO anodes have defined progress in chlorine and caustic production. By advancing their performance through custom engineering, re-coating expertise, and regeneration services, we help industries around the world maintain reliable operations while pushing the boundaries of efficiency and environmental responsibility. In every stage of the process—from chlorine evolution to the creation of its derivatives—our technologies provide the foundation for stable, sustainable, and cost-effective production.
