Comparison of the Efficiency of Ultraviolet/Zinc Oxide (UV/ZnO) and Ozone/Zinc Oxide (O₃/ZnO) Techniques as Advanced Oxidation Processes in the Removal of Trimethoprim from Aqueous Solutions

Table 3

The transfer efficiency of ozone and transferred dose.

ZnO = 500 (mg/L)	ZnO = 250 (mg/L)	ZnO = 50 (mg/L)	TMP (mg/L)
49.66	45.83	38.33	0.5	Transfer efficiency
−8.85	−15.61	−31.14	0.5	Transferred dose
69.33	64.5	57.66	1	Transfer efficiency
27.03	16.84	4.91	1	Transferred dose
84.33	83	80.83	5	Transfer efficiency
48.77	46.70	43.59	5	Transferred dose

^∗A negative sign indicates that the consuming ozone for 0.5 mg/L TMP is less than the outlet ozone.
