REMEDIATION AND DISINFECTION OF WATER USING JET GENERATED CAVITATION

Cavitation generated by DYNAJET ® cavitating jets can greatly enhance various chemical reactions, oxidize aqueous compounds, and disrupt microorganisms. Controlled laboratory experiments have established the ability of these jets to destroy microorganisms and oxidize a broad range of compounds including pesticides, Volatile Organic Compounds, arsenic, and reduce TOC (Total Organic Carbon). Experiments were conducted using a variety of cavitating jet configurations and operating conditions. Histories of the contaminant concentration reductions and destruction of selected bacteria strains were obtained from periodic sampling. Multiple order of magnitude reduction in e. coli concentration has been demonstrated. Comparisons with ultrasonic experiments show that jet-induced cavitation can achieve oxidation with up to two orders of magnitude greater energy efficiency
