For pH regulation potable water treatment processes use mainly lime (remineralization and decarbonation).
The dry lime stored on site (silo/super sacks/or hoppers) is transferred to a lime slurry tank or slaker (Quick Lime) if not fed directly to the stream of water.

In order to mix hydrated lime with raw water, the following pieces of equipment must be used :

  • Storage container : silo, Bulk Bag or 25 kg bag hopper
  • A shaftless screw feeder metering the product at the required feed rate
  • An isolation injector protecting the screw feeder from moisture and humidity
  • A lime milk slurry tank and its skid pump

The lime slurry solution level the water pH to a more acceptable alkalinity by precipitating bicarbonates that dissolves and prevent lime (tartar) formation.
