Antifoam Defoamer AF10
Highly effective liquid antifoam formulated for controlling foaming and priming in seawater distillation plants compatible with most antiscalants
New Generation with advanced formulation Antifoam Defoamer AF10 is a highly effective liquid product formulated to control foaming and priming in seawater distillation plants. Antifoam Defoamer AF10 has proven effectiveness during many years use in distillation plants throughout the world.
Antifoam for Seawater Desalination systems or other aqueous systems by RXSOL is a high-performance antifoam formulation based on a synergistic blend of modified alcohols and polymerised glycol ethers, specifically developed to control foam formation in seawater intake, pretreatment, and desalination systems.
The product rapidly collapses existing foam while providing extended foam suppression in seawater streams containing natural organic matter, algae-derived surfactants, hydrocarbons, biological contaminants, and suspended solids. The combination of fast-acting antifoam component and persistent foam-control properties of the polymerised glycol ether delivers both immediate knockdown and long-lasting antifoam performance.
The product is designed for continuous or intermittent injection into seawater make-up lines to minimize operational problems associated with foaming in desalination plants.
The foaming tendency of seawater in distillation plants is unpredictable. It is generally thought that foam is formed when organic compounds are concentrated in the brine, giving rise to surface active effects which increase the liquid film strength at phase interfaces. Antifoam Defoamer AF10 is not soluble in water. At use concentrations (0.05 - 0.1 mg/l) Antifoam Defoamer AF10 forms a micro-emulsion and during evaporation is incorporated into the surface liquid film of bubbles where it acts as a surfactant and reduces the film strength. The result is that the film readily ruptures and a stable foam does not form. In this way a uniform boiling or flashing action is achieved and carry-over is minimised.

Low dose levels, typically in the range 0.05 to 0.1 mg/l in the seawater feed stream, depending on feed water quality. Activity is not dependent on temperature. No need to alter dose level if top brine temperature (TBT) changes. Negligible steam volatility and carry over into the distillate.
RXSOL-51-2066-220 is antifoam emulsion and its more concentrated antifoam emulsion. It has excellent candidates for controlling foam in amine and glycol dehydration units. This is suitable products for gas plants and have excellent stability in the presence of salts, resulting in reduced deposits on the plant’s equipment. RXSOL-51-2066-220 help preserves foam control under the severe conditions of a dehydrating unit. These conditions can remove water from other antifoam emulsions, rendering them immediately inactive.
