Abstract

Ultrazvuk se koristi u metodi koja je svestrani postupak koji može učinkovito ukloniti veliki spektar onečišćivača u raznim vrstama voda. Ovdje je prikazana uporaba ultrazvučnih valova za uklanjanje organskih zagađivača. U početku se obrađuju konvencionalni postupci tretiranja vode te zatim nekonvencionalni postupci (napredni oksidacijski procesi) u koje spada i ultrazvuk. Uz opća svojstva ultrazvuka obrađuju se i opći aspekti sonokemije (tj. principi ultrazvuka i vrste reaktora), a potom se analizira utjecaj parametara ultrazvuka (ultrazvučna frekvencija, otopljeni plin, ulazna snaga, itd.) na pročišćavanja i kondicioniranje vode. Također se uzimaju u obzir prednosti i mane sonokemijskog postupka za sanaciju vode.

Abstract (english)

Ultrasound is used in a versatile method that is a process able to efficiently eliminate a wide range of pollutants in a variety of water types. Here, the use of ultrasonic waves for the treatment of organic pollutants is presented. Initially, conventional water treatment processes are processed, followed by unconventional processes (advanced oxidation processes), which include ultrasound. In addition to the general properties of ultrasound, general aspects of sonochemistry (i.e. principles of ultrasound and reactor types) are processed and then, the influence of ultrasound parameters (ultrasonic frequency, dissolved gas, input power, etc.) on water purification and conditioning is analyzed. The advantages and disadvantages of the sonochemical process for water remediation are also considered.
