Electrocoagulation (EC) Lab Test System for Water & Wastewater Treatment

System Overview

The Electrocoagulation (EC) Lab Test System is a compact, bench-scale platform designed for the evaluation and optimisation of electrocoagulation processes for water and wastewater treatment applications. It is ideally suited for research and process development, enabling users to investigate treatment performance under controlled laboratory conditions.

The system operates based on the electrochemical dissolution of sacrificial electrodes (typically aluminium or iron), generating coagulant species in situ to remove contaminants such as heavy metals, suspended solids, oils, colloids, and selected organic compounds.

Designed with flexibility and ease of use in mind, the unit allows precise control over key operating parameters including current density, treatment time, electrode configuration, and mixing conditions. This makes it highly suitable for:

• Method development and comparative testing across different water matrices
• Academic research and experimental studies
• Teaching and demonstration of electrochemical water treatment principles

Its modular configuration supports a range of electrode materials and operating setups, enabling users to simulate different treatment scenarios and generate data for process optimisation and scale-up assessment. Optional integrations such as dosing systems, temperature control, and monitoring instruments further enhance its capability for advanced research applications.

The transparent reactor design allows users to visually observe floc formation and separation behaviour in real time, supporting both educational demonstration and process understanding.

Overall, the EC Lab Test System provides a reliable and versatile platform for hands-on learning, experimental validation, and process development, helping users reduce uncertainty and make informed decisions before pilot or full-scale implementation.
