In water treatment oxidation processes are used to remove organic substances which are not biodegradable. If the oxidation is by hydroxyl radicals (OH radicals) it is called “advanced oxidation”. A common method for forming hydroxyl radicals is the irradiation of hydrogen peroxide with UV light. CE 584 demonstrates this process using a discontinuous falling film reactor.
Product Features
- The falling film reactor consists of a transparent tube open at the bottom
- At the top of the tube is a circular channel where raw water enriched with hydrogen peroxide is pumped
- The water flows as a thin falling film along the inside wall of the tube back into the tank, creating a closed water circuit
- A UV lamp in the centre of the tube irradiates the falling water to form hydroxyl radicals from hydrogen peroxide molecules
- The hydroxyl radicals oxidize organic non-biodegradable substances in the raw water
- The UV lamp is protected by a protective tube to shield against radiation
- Flow rate and water temperature are continuously measured
- Temperature is digitally indicated in the switch cabinet
- Samples can be taken from the tank for analysis
- Triethylene glycol dimethyl ether can be used to produce the raw water
- Analysis technology is required to evaluate the experiments
Benefits
- Clear demonstration of advanced oxidation processes using hydroxyl radicals
- Enables study of non-biodegradable organic substance removal in water treatment
- Continuous measurement and control of key parameters for precise experimentation
