|Title||The Impact of Ozonation on Wastewater Treatment and Disinfection|
|Title in Arabic||تاثير الاوزون في عملية معالجة و تعقيم المياه العادمة|
The main goal of the current research is to study the efficiency of ozonation on wastewater treatment and effluent disinfection, investigate the effect of ozonation on the oxidation of organic matter and Fecal coliform and investigate the wastewater quality parameters (COD , FC , NH3-N,TDS , pH) that can be affected by Ozone. The samples taken at two stages first stage was 4 liter from Gaza Wastewater Treatment Plant influent, the second stage was 10 liters from the effluent. In each experiment the samples were divided to two parts. First part without disinfection, the second part for disinfection. Results prove that wastewater treated by ozone leads to reduction of COD parameter ranging from (9%-64%), FC (25% – 83%). However, no major change for NH3-N ,PH and TDS parameters was observed. The ozonation process added to the samples at different time intervals (30, 45, 60, 90 and 120) minutes. Results show that COD reduction satisfy the Palestinian standard for wastewater reuse. Fecal Coliforms reduction observed satisfy the Palestinian standard for wastewater reuse, NH3-N reduction observed unsatisfied the Palestinian standard for wastewater reuse. In conclusion, the ozonation time has clear influence on the reduction of COD,FC and NH3-N.
