MMO Tubular Anode for Electrochemical Water Treatment

MMO Tubular Anode for Electrochemical Water Treatment

The effectiveness of electrochemical water treatment hinges heavily on whether the anode can perform consistently in complex wastewater environments. Our MMO Tubular Anode for Electrochemical Water Treatment at Baoji City ShenAo Metal Materials Co., Ltd. is designed specifically to handle the challenges of variable compositions and fluctuating water quality in industrial wastewater and circulating water systems. Built on Grade 1 or Grade 2 pure titanium tubes, it features a dense mixed metal oxide catalytic coating on the surface. This coating maintains stable electrocatalytic activity in water containing chlorides, organics, and across varying pH levels, enabling effective pollutant degradation or biocide action. The tubular structure provides favorable fluid distribution characteristics and gas venting capability, making it a reliable option for your electrochemical water treatment processes.

Why Choose Our Titanium Anodes?

• Stable Electrocatalytic Activity
  In chloride-containing environments common to water treatment, the MMO coating continuously generates highly oxidative active chlorine species. In organic wastewater treatment, the coating surface also produces reactive oxygen species such as hydroxyl radicals, effectively degrading a broad spectrum of organic pollutants while significantly reducing the need for additional chemical dosing.
• Engineering Advantages of the Tubular Structure
  The tubular configuration offers inherent benefits in fluid handling: water flows evenly between tubes with low pressure drop and minimal short-circuiting; gases generated on the anode surface rise along the tube walls and dissipate freely, avoiding gas accumulation. For high-throughput water treatment systems, this structural characteristic translates to higher current efficiency and lower operational energy consumption.
• Broad pH Tolerance
  Whether in acidic cleaning wastewater or alkaline degreasing effluent, the MMO coating maintains a stable chemical state. The coating resists dissolution or passivation in high-salinity, elevated-temperature, and pH-fluctuating environments, allowing your treatment system to remain stable even when facing variable influent quality.
• Easy System Integration and Scalability
  We can supply tubular anode assemblies with standard flanged connections or threaded joints, designed to fit your electrolytic cell or reactor configuration. Whether for new installations or retrofitting existing systems, the modular tubular anode strings offer flexible adaptation, facilitating convenient maintenance replacement and capacity expansion.

Technical Specifications

Real-World Applications

• Industrial Circulating Cooling Water Treatment: Used for electrochemical biocide and scale inhibition treatment in circulating cooling water systems of power plants, chemical facilities, and data centers, replacing or reducing chemical dosing.
• Refractory Organic Wastewater Treatment: For high-concentration, poorly biodegradable organic wastewater containing phenols, dyes, or pharmaceutical intermediates, providing pretreatment or advanced treatment via anodic oxidation.
• Chloride-Containing and High-Salinity Wastewater Treatment: In treating industrial wastewater with chloride ions or high salinity, the anode generates active chlorine species, enabling ammonia nitrogen oxidation and pathogen inactivation.
• Emulsion and Oily Wastewater Treatment: Applied for electrochemical demulsification and organic mineralization in oily wastewater from machining, steel cold rolling, and related industries.
• Water Reclamation and Advanced Purification: Serving as a pretreatment unit upstream of membrane systems to reduce organic loading, or as a disinfection unit downstream to ensure microbial safety of reclaimed water.

Frequently Asked Questions

Q: How do MMO anodes compare to boron-doped diamond electrodes in water treatment applications?
A: The two serve different application tiers. Boron-doped diamond electrodes offer stronger oxidation capability but at a higher cost, making them suitable for applications demanding exceptional treatment depth. MMO anodes provide a favorable balance between treatment cost and equipment investment, particularly advantageous for high-flow treatment in chloride-containing water, with more competitive operating expenses.

Q: How should the inter-tube spacing of tubular anodes be designed?
A: The spacing design should consider flow rate, conductivity, and current distribution uniformity. Typically, the inter-tube spacing is set at 1.5 to 3 times the tube diameter. Excessive spacing increases cell voltage, while overly tight spacing may lead to current shielding and gas accumulation. You can provide us with your electrolyzer dimensions and treatment capacity, and we will assist in optimizing the layout.

Q: What is the consumption rate of the anode when treating chloride-containing wastewater?
A: In chloride-containing water, the MMO coating primarily facilitates the chlorine evolution reaction, and the coating consumption rate is very low, typically in the milligram range annually. However, in wastewater containing fluoride ions or certain organic complexing agents, the consumption rate may increase. We recommend providing a full water quality analysis during selection so we can offer a more accurate lifespan estimate.

Q: How should scaling on the anode surface be addressed?
A: In systems with high water hardness, inorganic scale such as calcium carbonate may form on the anode surface. Dilute hydrochloric acid circulated online is typically sufficient for cleaning; the concentration and frequency depend on the degree of scaling. For organic fouling, a dilute alkaline solution can be used in combination. We recommend incorporating an online cleaning connection during system design.

Q: How can I tell if the anode coating needs replacement?
A: Two key indicators: first, the cell voltage has increased by over 1.0V from its initial value, with no improvement after cleaning; second, treatment effectiveness has declined, with effluent quality continuously deteriorating. We recommend maintaining regular monitoring records of cell voltage and treatment efficiency to anticipate coating condition and replacement timing.
