Lab Scale Electrocoagulation Wastewater Treatment Unit
A lab-scale electrocoagulation (EC) wastewater treatment unit is a miniature version of a system used to remove contaminants from water and wastewater using electricity. It's ideal for
researchers, and small-scale industrial applications to test and optimize the EC process for
specific wastewater streams.
Description:
The core components of a lab-scale EC unit typically include:
Reactor vessel: This tank holds the wastewater to be treated. It's often made of transparent
material for easy observation of the treatment process.
Electrodes: Two electrodes, typically made of aluminum or iron plates, are submerged in the
wastewater. One electrode is connected to the positive terminal (anode) and the other to the
negative terminal (cathode) of a power supply.
Power supply: A DC power supply provides the electrical current that drives the
electrocoagulation process.
Flocculation mechanism (optional): Some units might incorporate a stirrer or mixer to enhance
the collision and aggregation of contaminants during the process.
Sampling ports: These allow for collecting influent (untreated) and effluent (treated)
wastewater samples for analysis.
Features:
Compact size: Designed for laboratory use, these units have a small footprint and are easy to set
up and operate.
Adjustable parameters: Researchers can control various factors like voltage, current, treatment
time, and electrode material to optimize the EC process for specific contaminants.
Visible operation: The transparent reactor allows for visual monitoring of floc formation and
treatment progress.
Relatively simple setup: Lab-scale units are designed for ease of use and often require minimal
maintenance.
