Environmental Plant
wastewater Treatment System
ETA Power Generation Wastewater Treatment
- Ethanolamine (ETA) is used for pH control
- Conventional power plants use ammonia for pH control
- High concentrations of non-biodegradable COD and total nitrogen (T-N)
- Treated through oxidation using APS (Ammonium Persulfate) and reverse osmosis (RO) systems


Composite Oxidant (COA Reaction)
- Stepwise removal of TOC and total nitrogen (T-N) through the combined use of powerful oxidants
- Highly effective in removing non-biodegradable organic matter and nitrogen
Fenton Oxidation Treatment
Fenton reaction mechanism
- H₂O₂+ Fe² → Fe³ + OH- + OH*
- R- + OH* → CO2 + H₂O
Applied for the removal of non-biodegradable and toxic substances
Excellent capability to handle fluctuations in influent load

Ozone Oxidation Treatment
Fenton reaction mechanism
- R-R + O3 → R-COOH / R-CHO /R-OH + O3 → CO2 + H₂O
- Converts high-molecular-weight substances into low-molecular-weight substances
- Transforms hydrophobic substances into hydrophilic substances
- Converts non-biodegradable substances into biodegradable substances
- Reduces the toxicity of hazardous substances
Used for the removal of small amounts of non-biodegradable COD
Also applied as a disinfection system at final effluent discharge points
