Development of cavitation applications for the remediation of contaminated water
The development of cavitation applications for the remediation of contaminated water is presented. Per-formance data, such as scale control, corrosion and bacte-ria reduction, are presented. The screw propeller-type, pis-ton-type and membrane-type cavitators were developed and investigated. Chemical qualitative and quantitative analysis of the water before and after the cavitation ex-posed significant reduction of dissolute hydrocarbonate and other salts. At the same time the water becomes less alkali; filtrated, becomes more transparent and freezes more quickly; melted is suitable for drinking. A quantita-tive energy assessment of the possibility of using the cavi-tation for cracking of the hydrocarbons in water feedstock is performed.
