The use of cavitation in advanced oxidation processes (AOPs) to treat acidic effluents and process water has become a promising trend the area environmental protection. pH value – often acidified using an inorganic acid, is one key parameters optimization process. However, majority cases effect kind acid on effectiveness degradation not studied. present study describes results investigations hydrodynamic (HC) for treatment model effluent containing 20 organic compounds, representing various groups industrial pollutants. was three different mineral acids. It demonstrated that used strongly affects radical contaminants as well formation harmful secondary One important examples risk p-nitrotolune. Sulfuric only chemical acidification which caused effective with lack monitored type best during 6-hour - most much above 80% along 90% TOC removal obtained case sulfuric acid. Nitric provided lower (above 60% compounds). worst performance are reported hydrochloric below 50% compounds.

Chemical compounds containing nitro group (nitro-products) are a one of toxic by-products, that can be formed during wastewater treatment processes. In case presence nitrite or nitrate ions, the formation nitro-products advanced oxidation processes (AOPs) is very common. It caused by reactive nitrogen species (RNs) such as radical (NO3•), (NO2•), oxide (NO•) and peroxynirite (ONOO–). fact, oxidative degradation N-containing pollutants releases nitrate, ammonium ions. some cases, secondary reactions mineralised (nitrate ions) with parent intermediate compound generate next several nitro-products. The more comparing to primary act precursors nitrogenous disinfection by-products. Moreover, studies reported unexpected degradation. special attention should made monitor minimize these effects. De-nitration initial nitro-compounds induces various in AOPs. was observed for UV light driven, Fenton persulfate based sonochemical fixation key mechanism ultrasounds Therefore, this paper focused on comparison AOPs terms mechanisms associated environmental issues.

Tetracycline (TC), a frequently used drug for human and veterinary therapeutics, is among the most common antibiotic residues found in nature. Lack of advanced treatment techniques wastewater plants (WWTPs) to remove residual TC from domestic hospital poses serious environmental risk. It important have an insight into different efficient removal surface water WWTPs. The aim this review discuss nature occurrence present overview various removal. include oxidation processes (photolysis, ozonation, catalytic/UV light-based degradation), membrane filtration, reverse osmosis, adsorption techniques. Adsorption integrated are widely studied methods, they accepted because less cost, reusability, toxic-free Further, uses types catalysts photodegradation sorbents also presented. Finally, importance green nanocomposite sustainability emphasized.
