| description abstract | It has been proven that the concept of using a high pressure water jet (HPWJ) to pretreat wastewater for the enhancement of ultraviolet (UV) disinfection of wastewater is an effective and cost-efficient alternative compared with the widely studied ultrasonic method. This study addresses: (1) the effectiveness of the pretreatment with a low pressure water jet (LPWJ) under similar experimental settings to the previous HPWJ study, (2) the water pressure impacts on bacteria in the treated wastewater, and (3) the difference in electrical energy consumption under treatment with different pressures. The results show that with the tested primary clarifier overflow (PCO), there were no real differences in enhancement of UV disinfection with LPWJ pretreatment operating under a tested pressure range from 0.97 to 6.80 MPa. More than 1 log unit improvement of UV disinfection efficiency can be achieved under all the tested pressures compared with treatment by UV irradiation alone when the UV dose is in the | |
