Here are the main features:

  • Four machine sizes: 3 hp, 5 hp, 10 hp, and 15 hp
  • Systems scalable for clearwells and tanks from 10,000 gallons to 100,000,000 gallons, and tank flow rates up to 100,000,000 gallons per day
  • Hydraulic system design allows for partial or total shutdown of units during periods of low TTHM, without losing any mixing required for prevention of ice damage or maintaining top water quality
  • Because their are no significant friction or lifting losses, 98% of the energy consumed by the pump is converted to stripping TTHM at the nozzle assembly, compared to 50-60% for fixed-ceiling nozzle design
  • Patented long-life nozzle and intake design treat all incoming water, minimize THM formation downstream
  • Nozzle angle assures no damage to tank coatings
  • Ventilation blowers for headspace included with all systems
  • All models fith through a 24"x24" or larger hatch opening, eliminating the need to install a new larger hatch or special lifting equipment
  • Factory installation is usually available for entire system except the wiring by the local electrician
  • No infrastructure piping is required, and no modifications to the tank or clearwell other than small access openings for wire and the headspace air ventilation
  • Small footprint units are easily movable and removable for any future interior tank work
  • If the TTHM problem changes, this equipment is portable and can easily be moved to another area of town or else sold to another water district
  • Low-maintenance, long-life design
  • Two year parts and labor warranty, factory maintenance plans available
  • Full-scale pilot studies can be provided, with purchase options
