Economy

By reducing down-time, productivity is increased. by protecting metal and by uniform leaning of the surface equipment life is prolonged and performance made superior. The above information is adequate for commonly encountered problems of descaling.

Handling & Storage

Safety

•    No Fumes Avoid contact with skin or eyes. Wear Cup-type, rubber or soft plastic-framed goggles, protective clothing, and rubber gloves must be worn when handling.

•    Keep in a tightly closed container. Protect from physical damage.

•    Store in a cool, dry, ventilated area away from sources of heat, moisture and incompatibilities.

•    Containers containing this material may be hazardous when empty since they retain product residues (dust, solids); observe all warnings and precautions listed for the product.

•    Ensure as low exposure as possible. Local exhaust ventilation is generally preferred as it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area.

Formation of Calcium Sulfate is main cause for SCALE formation :::

The principal problem potential posed by sulfate ions in water is the possibility of calcium sulfate scale formation.  Precipitation of calcium sulfate can occur when high concentrations of both calcium and sulfate exist simultaneously.  There are three primary areas of water treatment in which calcium sulfate precipitation may occur boilers, cooling systems, and ion exchangers operating in the hydrogen or acid mode.

In boilers, calcium sulfate scale formation has been reduced to a minimum by modern treatment practices.  The low hardness levels largely preclude calcium sulfate boiler scale.    By contrast, cooling systems are subject to calcium sulfate scale deposition because the makeup is usually not treated for hardness removal.  Cooling water is usually treated with sulfuric acid for pH control, and the makeup is cycled, i.e. concentrated.  Calcium sulfate scale deposition can  result unless the cycles of concentration are properly controlled in conjunction with the proper use of scale control chemicals.  Cation ion exchangers regenerated with sulfuric acid also can pose a major calcium sulfate problem. Calcium sulfate precipitation can be avoided by controlling the acid concentration and the flow rate through the exchanger.
