Multi-Functional Oxidizing Water Treatment
White Squall is a highly active, multi-functional and multi-site oxidizing water treatment for use in water culture based hydroponic systems. White Squall is effective when used as either a preventative or treatment application to remove mineral deposits (descale), algae and bacterial biofilms that can develop in hydroponic nutrient reservoirs. It is also highly effective in creating an aqueous environment that is unfavorable for the development of microorganisms such as bacteria, fungi, viruses and other pathogens.
White Squall’s principle constituent is hypochlorous acid (HOCl), an oxyacid of chlorine that acts as a weak acid but demonstrates powerful oxidizing properties. It is the oxidizing property of White Squall that contributes to its highly effective descaling of mineral deposits and destruction of bacterial biofilms.
Hypochlorous acid is also acknowledged to be among the most potent disinfectants (sanitizing agents), yet it remains non-toxic to humans and other mammals. In fact, hypochlorous acid is produced by the human body’s immune cells to fight infections.
White Squall’s safety extends to plants and can be used at any stage of plant growth. It can also be used as a final flush to help reduce residual mineral build-up. White Squall should be used in a pH controlled environment. Its hypochlorous acid constituent will exist as the dominant chlorine species under pH conditions ranging from 2.0 to 7.0. Maintaining the water pH at this range provides the greatest performance.
Use of White Squall for Descaling
It is well recognized that calcium carbonates (CaCO3) and magnesium carbonates (MgCO3) are two of the main components of scale that are commonly encountered in hydroponic industries. Calcium and magnesium carbonate scale often grows extensively on equipment and parts, causing major operational difficulties. Scale also provides sites for bacterial or fungal accumulation.
Hypochlorous acid reacts with both calcium carbonate and magnesium carbonate resulting in chloride salts being formed (CaCl2 and MgCl2) that are highly soluble in water. These soluble salts can then be removed from the system quite easily.
CaCO3 + 2HOCl –> CaCl2 + CO2 + H20 + O2
MgCO3 + 2HOCl –> MgCl2 + CO2 + H20 + O2
In addition, the oxidative property of White Squall will cleave and make available for removal, structures of biofilms and organic matter in nutrient solution tanks that may serve as nucleation attachment sites for calcium carbonate and magnesium carbonate. Remnants of biofilms and organic matter can be washed away leaving surfaces clean. This action serves as a means of inhibiting scale formation.
