The experiments was realized with two types of equipment: ultrasound bath UCD-150 and sonotrode UP 200 Ht. The experimental results showed high efficient removal for all three compounds: Tetrachloroethene 93.8%, 1, 1, 2-Trichloroethane 92.9% and Trichloroethylene 86.6% in bath ultrasound treatment after 50 min. The ultrasound efficiency treatment depend by the sonotronde diameter. The degradation of Trichlorethylene and 1, 1, 2 -Trichloroethane is much better for sonotrode with 14 mm diameter (92.1% respectively 92.7%) than for sonotrode with 40 mm diameter (71.9% and 61.6%), while for Tetrachloroethene values were very close, 88.7% respectively 89.4% for the same above mentioned diameters.en-USChlorinated organic compoundsSonochemical processesUltrasonic irradiationArticle10.37358/RC.17.5.5602
