Solar-based detoxification of phenol and p-nitrophenol by sequential TiO2 photocatalysis and photosynthetically aerated biological treatment

Kinetics and metabolic versatility of highly tolerant phenol degrading Alcaligenes strain TW1

“…has been successfully used for the treatment of real industrial wastewater [29] and strain TW1 was specifically used to treat artificial wastewater containing phenol and nitrophenol [41]. The present study confirms the potential of Strain TW1 as an efficient and versatile microorganism for the bioaugmentation of highly contaminated effluents.…”

Tetracycline removal during wastewater treatment in high-rate algal ponds

“…The PAR was measured with a PAR quantum sensor equipped with a WatchDog data logger (Spectrum Technology, USA) and UV irradiance was measured using a UV-AB light meter (Sper Scientific, USA). O 2 gaseous composition was quantified by GC-TCD analysis (Shimadzu, Japan) with protocol adapted from Essam et al [14].…”

Enhanced photocatalytic–biological degradation of 2,4 dichlorophenoxyacetic acid

“…11,12 The use of UV irradiation with and without the assistance of an oxidizing agent (UV/TiO 2 , UV/H 2 O 2 ) alone or combined with the biological methods proved to be very efficient, cheap and sustainable as in case of wastewater treatments. 13,14 Therefore, physical or physicochemical pre-treatments are usually important in case of substances which are highly toxic to the biological degraders or recalcitrant materials where the pre treatment changes these materials into less toxic and biodegradable metabolites. [15][16][17] In this prospective, the present study investigated the optimum method to detoxify and bioremediate 2,4-D using biological consortia alone or in combination with photo-catalytic pre-treatment against increasing concentration of 2,4-D.…”
