Directions for use
NALFLEET™ Hardness Treatment 7208 should be fed continuously in order to properly protect the boiler. NALFLEET™ Hardness Treatment 7208 can be fed neat or in any convenient dilution made up in soft water or cooled condensate. NALFLEET™ Hardness Treatment 7208 should be dosed using individual chemical dosing unit, must not be mixed with oxygen scavengers or condensate system corrosion inhibitors in concentrated form (e.g. concentrated chemical products should not be mixed together).
Sampling and Testing
NALFLEET™ Hardness Treatment 7208 is normally used in conjunction with NALFLEET™ Alkalinity Control treatment in a conventional alkaline phosphate treatment programme for HP boilers, where independent control of phosphate and alkalinity control is required.
Dosing and Control
The dosage of NALFLEET™ Hardness Treatment 7208 depends on a number of operational factors such as feed-water quality, boiler design and steam rate. Control of NALFLEET™ Hardness Treatment 7208 is by a simple test to give the required level of phosphate (as PO4) in the boiler water. A simple Hardness Treatment test kit is available for this purpose.
NOTE: Dependent on water quality, NALFLEET™ Hardness Treatment 7208 dosed at 0.25 liters/ton will increase the phosphate reserve by the order of 10mg/l.
