Influence of Cavitation Treatment on the Physicochemical Properties of Calcium Hydroxide

Phosphor Removal from Waste Water Using Hydrodynamic Cavitation

“…To overcome the issue of low solubility and large surface area hydrodynamic cavitation can be used. Cavitation has been shown to increase the kinetics calcium hydroxide by temporarily increasing temperature of calcium hydroxide in turn increasing dissociation of surface molecules helping to alleviate the problem of poor solubility [21]. Hydrodynamic dynamic cavitation allows for greater dissociation of surface molecules by causing the violent collapse of vapor filled cavities.…”

“…It is probable that phosphate and calcium hydroxide can react directly on the surface of the calcium hydroxide particles after surface disassociation. Yavors'kyi hypotheses [21] the cavitation can create Ca(OH) 2 → Ca(OH) + on the surface of calcium hydroxide. This phisochemical reaction may provide a base for the formation of calcium phosphate salts on the surface of the Ca(OH) 2 when phosphate is present in the solution.…”
