Features & Application

01.

Municipal water treatment

In municipal water treatment systems, acidic water electrolysis titanium anodes are used in disinfection and auxiliary oxidation processes where stable current output and long-term durability are required. The titanium-based anode maintains consistent performance under acidic conditions, supporting continuous operation and reliable water quality control while reducing maintenance frequency.

02.

Industrial wastewater treatment

For industrial wastewater treatment, these titanium anodes are applied in electrochemical oxidation and advanced treatment stages, particularly in acidic or chloride-containing effluents. Their corrosion resistance and stable electrochemical behavior make them suitable for handling complex water compositions, helping improve treatment efficiency and operational stability in long-running systems.

FAQ

Q1: What determines the service life of the anode?

A: Life mainly depends on current density, acid concentration, and temperature. Under standard conditions (pH 2, 100 A/m²), it typically lasts 9000–12000 hours - meaning fewer shutdowns and reduced maintenance costs.

Q2: Can it be used for acid cleaning or low-pH wastewater treatment?

A: Yes. Its Ru–Ir coating remains stable in strong acid, ensuring safe operation and consistent current output in cleaning or recovery systems.

Q3: Which titanium grade should I choose?

A: Grade 1 is preferred for mild acid with high conductivity, while Grade 2 suits high-pressure or long-cycle systems. Our engineers can recommend the best match for your plant.

Q4: Do you support third-party inspection?

A: Yes. SGS and other authorized labs can verify coating, adhesion, or dimensions before shipment.
