Prominent 2 Tank Saturator - Vacuum Load System


The ProMinent® 5kg Bottle Loader Sodium Fluoride Saturator (Up-flow) package has been specifically designed & developed for adding fluoride into town water supplies.

ProMinent Fluid Controls Pty Ltd specialises in the supply, installation and commissioning of fluoridation equipment; and has supplied in excess of 65 fluoridation plants over the past 35 years.

Sodium Fluoride has a reliable saturation solubility of 4.05%. By keeping excess sodium fluoride powder in a dissolving tank, a constant 4.05% Sodium Fluoride (NaF) saturated solution is maintained. This is then dosed into the water supply, via a ProMinent® Gamma X Metering Pump, in proportion to the mains 4-20 milliamp flow signal. 

Chemical Loading:

  • Chemical Loading via a Prominent Vacuum Loader system.
  • Low dust.
  • Integrated dust reducing vent tank.
  • Exhaust filtered and piped outside of the room.
  • Increased operator safety.


  • Twin tanks integrated into a single package. 
  • Custom fabricated tank / baffles.
  • Two blank sides on the tanks, allowing placement in the corner of the room.
  • Available as a Vacuum Loader or with a Prominent Bottle loader fitted.
  • One tank makes a batch, the chemical is aggressively mixed and then allowed to settle.
  • The batch is transferred regularly to top up the second tank.
  • Second tank contains clean saturated fluoride solution. Ready to be dosed at any time.
  • Only a small amount of fluoride is required to be loaded into the system. This will still maintain complete saturation of the solution in the second tank. Unlike a conventional saturator which requires large volumes of chemical to operate.
  • When tank cleaning is required, only a small amount of waste chemical needs to be removed.

Water Softener:

  • A water softener and water heater are supplied with the system.
  • Softener removes the “hardness” from the service water. The fluoride in the tank lasts longer with the “hardness” removed.
  • Automatic regeneration of the water softener does not require intervention by the operator.
  • The water heater heats up the water entering the tank, this results in less time for chemical to saturate.
  • These components are fully integrated into the system. 

Equipment: General

  • Compact system made in modules.
  • Easy to place in the room, especially with restricted space.
  • Layout variation possible with modular design, allows for difficult rooms.
  • Easy to wire junction box in each module. Connect with multicore cabling. 
  • One system can operate over a large flow range. This allows the system to be upgraded to larger flow rates in the future.
  • Lower waste generated and easier cleaning.
  • Latest modern design made to be very efficient.
