Trihalomethanes (THMs) are chemical compounds that form when natural organic matter in water reacts with chlorine during the disinfection process. THMs are a suspected carcinogen and regulated in many countries. Exceedence of the Maximum Contaminant Level (MCL) for THMs are among the most common violations of the EPA Stage II DBP rule in the United States.
Unlike most THM removal technologies that involve large-scale changes to the water treatment plant, the PAX TRS™ (Trihalomethane Removal System) is a custom-designed, energy-optimized system of mixers, aerators and ventilators that converts ordinary water storage tanks into water treatment systems.
By implementing a thoughtful combination of sub‐systems that include PowerVent® active headspace ventilation, PAX Mixers for powerful tank mixing, NSF certified surface aerators and Neptune-Toolbox modeling, PAX TRS™ systems have become the leading choice for utilities and engineers that require guaranteed levels of THM reduction in water storage tanks.
- Tank headspace ventilation equipment
- Aggressive tank mixing devices for removing THM concentration gradients
- Surface aeration and spray aeration options for additional mass transfer where high levels of THM removal are required
- Sophisticated tank modeling and process control for smart energy management
- Guaranteed THM removal rates
- NSF61 approved materials
- Active headspace ventilation creates ideal conditions to volatilize THMs
- Robust equipment including non-clogging aeration nozzles and reliable surface aerators
