Introduction

The Batch Electrochemical Water Treatment Test Station is a versatile laboratory platform designed for the investigation and development of a wide range of electrochemical water treatment processes. Operating in batch mode, this test station allows precise control over experimental conditions, including current, voltage, temperature, and mixing, making it ideal for both research and process optimization.
Its modular design supports multiple electrochemical treatment methods, including:
a) Electrochemical coagulation for the removal of suspended solids, metals, and phosphates.
b) Electrochemical oxidation for the degradation of organic contaminants and advanced oxidation processes (AOPs).
c) Electrochemical reduction for the treatment of specific pollutants, such as nitrate or hexavalent chromium.
d) Electroflotation to assist in the separation of flocs and colloids.
e) Electrochemical disinfection through in-situ generation of reactive species.

This test station is suitable for fundamental studies, method development, and pilot-scale experiments, providing researchers and engineers with a flexible and reliable tool to explore, optimize, and scale electrochemical water treatment technologies. Its batch operation ensures easy sampling, monitoring, and adjustment of reaction parameters, enabling thorough analysis of reaction mechanisms and process efficiency.

This is the list of electrode materials typically used in a Batch Electrochemical Water Treatment Test Station, organized by type and common applications:
1. Anode Materials (for oxidation reactions)

• Boron-Doped Diamond (BDD) – very high oxidative power; used for degrading organic pollutants, generating hydroxyl radicals.
• Dimensionally Stable Anodes (DSA, e.g., Ti/IrO₂, Ti/RuO₂) – widely used for electrochemical oxidation, chlorine generation, and disinfection.
• Platinum (Pt) – strong oxidation, often for small-scale lab experiments; expensive but highly stable.
• Mixed Metal Oxides (MMO, e.g., Ti/Ta₂O₅-RuO₂, Ti/IrO₂-RuO₂) – good stability and moderate cost; used in both oxidation and chlorine generation.
• Graphite / Carbon-based electrodes (Carbon Felt, Carbon Cloth, Graphite Plate) – good for organic oxidation, cost-effective, often combined with electrochemical reactors for research.

2. Cathode Materials (for reduction reactions)

• Stainless Steel (SS) – widely used, cost-effective, good for general electrochemical reduction.
• Platinum (Pt) – highly active for hydrogen evolution and reduction reactions.
• Nickel (Ni) – good for hydrogen evolution and reduction of nitrates.
• Carbon-based cathodes (Carbon Felt, Graphite) – inexpensive, large surface area; used in batch experiments for electro-reduction processes.

3. Specialized / Research Electrodes

• Mixed metal oxide cathodes – for specific electrochemical reactions.
• Ti-based cathodes with coatings (Ti/Pt, Ti/Ni) – for corrosion resistance in aggressive solutions.
• 3D porous electrodes (Carbon Foam, Reticulated Vitreous Carbon) – for enhanced mass transfer and high surface area.
