MMA-L70-HPI
TYPE – Specialised High Performance Antiscalent and Corrosion Inhibitor for Evaporator and Process Waters such as Mining, Iron and Steel, Paper & Pulp, Sugar Processing and Critical Heat Exchange Operations. Suitable for use in Reverse Osmosis Systems.
MMA-L70-HPI is a specialized reacted polymer containing polymeric antiscalents, sequestrants 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. MMA-L70-HPI also exhibits anti-corrosion properties.

MMA-L70-HPI 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. MMA-L70-HPI is specifically utilised where total hardness can reach 800mg/l as CaCO3 or where calcium sulphate presence is at 2500mg/l as CaSO4. MMA-L70-HPI may be applied online as an descalent, but higher residuals will be required – estimate 100-200mg/l.
There is a direct test method to determine product residual in these systems.
MMA-L70-HPI 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. MMA-L70-HPI must be protected from freezing. Protective clothing such as gloves and goggles should be worn when handling MMA-L70-HPI.
