Integrated Micro-electrolysis Device

Updated: 2026-09-18

Overview

The Integrated Micro-electrolysis Device is a specialized equipment designed for advanced wastewater treatment. It leverages electrochemical principles to degrade pollutants through redox reactions, making it particularly effective for industrial effluents containing refractory organic compounds or heavy metals. The device integrates electrodes, reaction chambers, and control systems into a single unit, optimizing space and operational efficiency. Its modular design allows scalability for different industrial applications, from small-scale workshops to large manufacturing plants.

Structure and Working Principle

The device consists of a reactor vessel filled with granular electrodes (often iron-carbon or other catalytic materials), influent/effluent ports, and a power supply system. When wastewater passes through the reactor, electrolytic reactions generate reactive species like hydroxyl radicals, which oxidize pollutants. Micro-electrolysis occurs via galvanic cells formed between dissimilar electrodes, enhancing contaminant breakdown without excessive energy input. Some models include auxiliary components like pH adjusters or sludge collectors to optimize performance.

Key Features

1. **High Efficiency**: Achieves up to 90% removal rates for COD (Chemical Oxygen Demand) and heavy metals like chromium or cadmium. 2. **Energy Savings**: Operates at low voltages (typically 1–5V), reducing power costs compared to traditional electrolysis. 3. **Durability**: Corrosion-resistant materials extend lifespan in harsh wastewater environments. Automated controls enable real-time monitoring of key parameters (e.g., current density, reaction time), ensuring consistent treatment quality. The compact footprint suits facilities with space constraints.

Application Areas

1. **Chemical Manufacturing**: Treats dye intermediates, pesticide residues, and synthetic wastewater. 2. **Electroplating**: Removes hexavalent chromium, cyanide, and nickel ions. 3. **Pharmaceuticals**: Degrades antibiotic residues and high-concentration organic waste. Other sectors include petrochemicals, textile printing, and landfill leachate treatment. The device is often paired with biological or membrane systems for comprehensive water reuse solutions.

Maintenance and Precautions

Routine maintenance includes electrode replacement (every 1–3 years), sludge removal, and inspection of electrical components. pH should be maintained between 2–4 for optimal iron-carbon reactivity. Avoid overloading the system with influent exceeding design concentrations, as this may shorten electrode life. Safety measures include grounding the equipment and using PPE during maintenance due to potential exposure to acidic conditions.

B2B Procurement Guide

1. **Capacity Assessment**: Calculate daily wastewater volume and pollutant load to determine required device size. 2. **Customization**: Opt for modular designs if future expansion is anticipated. 3. **Supplier Evaluation**: Prioritize vendors with industry certifications (e.g., ISO 14001) and case studies in your sector. Total cost considerations should include installation, consumables (electrodes), and energy use. Request pilot testing for complex wastewater streams to verify performance claims.
