Specialized High Performance Antiscalent for Reverse Osmosis Membranes; Process Heat Rejection Systems & Evaporators

ROA-S100-HI is a specialized reacted polymer containing polymeric anti-scalents 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.

It is supplied as a unique powder material and reconstituted nominally to a 25% solution on a
mass: mass basis.

ROA-S100-HI is dosed to reverse osmosis feed water at a nominal rate of 3 to 7 mg/l. However, specific analysis of the water will determine the exact dosage required. For critical heat exchangers it is recommended that satellite dosing occur as close to the heat exchanger as possible and controlled at 8 to 13mg/l. Dosage to evaporators and standard cooling systems feed/make-up should be at 30-50 mg/l divided by the effective cycles of concentration.

There is a direct test method to determine product residual in these systems.

Innovation: It’s part of our DNA

Large enough to deliver. Small enough to care.

Innovation is everywhere at Blue Reef. For example, the chemical products which we have produced for the anti-scalent market are unique in every way. Our “HEXAMER” based products are formulated and manufactured employing processes previously never used in the manufacture of water treatment products.
Not only does this make the products far more stable than traditional inhibitors, but one is able to actually test for the active aspect in the product. This takes scale inhibition and scale removal to a new level in that chemical dosing rates can be calculated very accurately resulting in cost savings and increased efficacy.

A further innovation is that all of our products are available in liquid and dehydrated powder form. These dry products are unique. All that one has to do to produce a liquid version of the same product is to “JUST ADD WATER” and mix.

This makes for transportation of product over long distance/over border logistics extremely easy as packing for transportation is far easier and so much safer.
