Abstract
ABSTRACT
In the sonochemical process, the organic pollutant can be destroyed by direct pyrolysis in the cavitation bubble or by free radical attack in the interfacial region. The objective of this study is to examine the technical feasibility of the sonochemical process for the destruction of organic contaminants. Batch experiments were conducted with trichloroethylene (TCE) employing a microprocessor-controlled 20-kHz ultrasound source. This paper presents results on the effect of the following parameters on reaction rate: compound concentration, dissolved gases, background water matrix, bi-carbonate concentration, pH, and suspended solids.
Key words:
Sonochemical destruction; sonolysis; ultrasound; water treatment; trichloroethylene
