EOXCELL INTRODUCTION

In the field of wastewater treatment, Electro-Oxidation (EO) is emerging as a next-generation technology. It is capable of removing recalcitrant organics such as dyes, pharmaceuticals, PFAS, and toxic compounds that conventional biological processes fail to degrade [3].


EOXCELL®, developed by YASA ET, is a laboratory-scale Electro-Oxidation Test Cell equipped with Boron-Doped Diamond (BDD) electrodes – widely considered the “gold standard” material in electrochemical oxidation because:

  • Wide electrochemical window → continuous generation of hydroxyl radicals (•OH)

  • High durability → 3–5 years lifespan, compared with 6–12 months for Fe/Al electrodes

  • Corrosion resistance → suitable for saline and high-TDS wastewaters

  • Scalability → lab results can be directly used for industrial system design

EOXCELL is not just a testing device, but a bridge from laboratory research to full-scale industrial application.

HOW TO USE EOXCELL


Basic operation steps:

  1. Install the test cell – connect EOXCELL to S-EC/EO Test Kits (1A, 5A, 10A)

  2. Select electrodes – BDD cathode with Ti/Ru-Ir or Titanium anode [3]

  3. Set operating conditions – current density between 10–50 A/m² depending on COD/BOD targets [5]

  4. Run the system – fill with sample wastewater, start the recirculation pump, apply voltage

  5. Collect samples – measure COD, BOD, TOC, or specific pollutants after treatment

Operating Modes

  • Batch Mode – recommended for preliminary tests and contact time evaluation

  • Continuous Mode – suitable for scale-up studies to simulate industrial operation

CUSTOMIZED BDD PLATES SERVICE


In addition to EOXCELL, YASA ET provides customized BDD electrode fabrication for specific applications.

📌 Standard Options

  • BDD (10 µm coating) → 296 USD/plate

  • BDD (20 µm coating) → 498 USD/plate

  • Substrates available: Titanium or Niobium


📌 Customization Options

  • Fabrication according to client drawings (size, thickness, shape)

  • Choice of substrate:

    • Silicon-based BDD → cost-effective but less resistant to fluoride

    • Niobium-based BDD → highly resistant to fluoride and aggressive media, longer lifespan [3]

  • Single or double-sided coating

Customized plates allow researchers to simulate real operating conditions and generate more accurate scale-up data.

WHY BDD IS SUPERIOR


BDD electrodes outperform conventional electrode materials in several aspects:

  1. Wide potential window – hydroxyl radicals (•OH) with oxidation potential of 2.8 V [3]

  2. Durability & Stability – 3–5 years lifespan vs. ~2 years for Ti/Ru-Ir, ~6 months for Fe/Al

  3. Low passivation risk – reduces downtime for cleaning and maintenance [3]

  4. Energy efficiency – pulse current mode reduces energy consumption by 15–25% [5]

  5. Versatility – effective for wastewater treatment, disinfection, and environmental sensing [4]


MARKET TRENDS & INSIGHTS


According to MarketsandMarkets (2025), the global Electro-Oxidation market is expected to grow from USD 1.6 billion in 2025 to USD 2.1 billion by 2030, with a CAGR of ~6% [1].

Key Drivers:

  • Regulations – EU and US are tightening standards for PFAS and micropollutants [6]

  • Zero Liquid Discharge (ZLD) – industries in Asia and the Middle East are adopting EO/BDD to meet ZLD mandates [1]

  • R&D Expansion – universities and research labs are increasingly investing in BDD electrochemistry [3]


CASE STUDY


Refinery Wastewater – Pilot Scale (2025)

  • Achieved 99.9% phenol removal in 20 minutes at 10 V

  • COD and BOD reduced by ~50%

  • Energy consumption: 0.25–0.45 kWh/m³ [2]

Hospital Pharmaceutical Wastewater

  • BDD electrodes successfully degraded antibiotics and pharmaceuticals that conventional biological treatment failed to remove, without forming toxic by-products [4].


SCIENTIFIC ADVANCES


  • BDD Film Enhancement – 2025 research shows that nanodiamond seeding improves crystal density, lowers resistivity, and increases electrode lifespan [5].

  • Environmental Sensors – BDD electrodes are used in toxin and pathogen detection due to low adsorption and high selectivity [4].

  • PFAS Elimination – WSP announced successful on-site PFAS destruction using EO/BDD in 2025 [6].


CONCLUSION


EOXCELL is more than just a test kit – it is a comprehensive research platform for studying electro-oxidation with BDD electrodes. It enables researchers and industries to:

  • Test pollutant removal under real wastewater conditions

  • Evaluate energy consumption and optimize parameters

  • Generate reliable data for scaling up to full industrial systems
