Light Environmental offers full-scale treatment systems employing different advanced oxidation processes. The purpose of all oxidation technologies is to produce hydroxyl radicals (-OH), a highly reactive oxidizing agent that reacts with and destroys most organic pollutants in water. There are a variety of advanced oxidation approaches commercially available. Each is best suited for a scope of wastewater treatment applications.
Light Environmental's Chemical Ultraviolet Solution is an advanced oxidation process that destroys dissolved organic contaminants in contaminated water. In these processes, a proprietary high-powered, medium pressure lamp emits high energy UV radiation through a quartz sleeve into the contaminated water. Oxidizing agents, hydrogen peroxide and ozone are added to the contaminated water and is activated by the UV light to form oxidizing species called hydroxyl radicals, via:
O3/H2O2 + UV¡ª¨C> 3(•OH)
The hydroxyl radical reacts with the dissolved contaminants, initiating a rapid cascade of oxidation reactions that ultimately fully oxidize or mineralize the contaminants. The success of the system is based on the fact the rate constants for the reaction of organic compounds with the -OH radical under the presence of UV light is 1,000-1,000,000 more effective than the effect of the oxidizing agent alone.
Advantages to our Chemical Ultraviolet Wastewater Treatment:
- On-site destruction treatment technology
- No phase transfer required, thereby eliminating secondary handling
- Efficient for a wide range of contaminants types and concentrations including chlorinated alkenes, aromatics, phenols, PAHs, PCBs, Alcohols, and Ethers
- Low maintenance and operating requirements
- Quiet and unobtrusive equipment
- Can be carried out at ambient temperature and pressure
