CWD-L40P
TYPE – Specialised High Performance Antiscalent for Cooling Water, Evaporator and Process Waters such as Mining, Iron and Steel, Paper & Pulp, Sugar Processing and Critical Heat Exchange Operations.
CWD-L40P is a specialized reacted polymer containing polymeric antiscalants and dispersants. It is designed to inhibit precipitation of calcium, magnesium and iron salts in the form of carbonate, sulphate and oxalate compounds. It is also effective in the binding of other metallic salts such as aluminium, zinc, strontium and barium.

CWD-L40P is dosed as follows :
Dosage required will vary according to the potential precipitative salts present and a detailed analysis of the process water is recommended.
Depending upon water flow velocities and applicable cycles of concentration, dosages will vary from 3 mg/l to 20mg/l. CWD-L40P is specifically utiliised where total hardness can reach 800mg/l as CaCO3 or where calcium sulphate presence is at 2500mg/l as CaSO4. CWD-L40P may be applied online as a descalent, but higher residuals will be required – estimate 100-200mg/l.
CWD-L40P can be stored for up to 24 months from the date of manufacture, in its original, sealed packaging, at room temperature in a dry area. Containers must be kept undercover and out of direct sunlight.
This product can be safely stored in plastic type holding tanks designed to manage the specific gravity listed. CWD-L40P must be protected from freezing. Protective clothing such as gloves and goggles should be worn when handling CWD-L40P.
