Reduction of bromate formation by catalytic ozonation using granular molecular sieve MCM-48
Ozonation has been broadly used in drinking water treatment due to its strong ability in organic degradation and bacteria disinfection. However, the formation of undesirable by-products has severely restricted the further application and dissemination of the ozonation process. Bromate (BrO3), which has Class II B carcinogenic potential, is one of the most intractable by-products generated during ozonation of water containing bromide (Br). The maximum contamination level of BrO3 is set at 10 ug/L by many nations including China. In many regions of China, the surface and ground waters have a considerably high content of Br. However, most water plants have no effective measures to control the formation of BrO3 during ozonation. As a result, B1O3 has become a great challenge for water plants that adopt ozonation for water treatment.
