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.
