The improvement test of typical two-stage up-flow biological aerated filter ( UBAF ) with ceramsite was performed using the characteristics of different flow BAFs and the optimized backwash operation .
In this paper , productive experiment was conducted on biological ceramisite filter , one of BAFs , to pretreat the upstream water of Huangpu River at the scale of 5000t / d.
Biological aerated filters ( BAFs ) is a recently developed process for wastewater treatment , media selection is critical in the design and operation of BAFs to achieve qualified effluent quality requirements .
曝气生物滤池是一种新兴的污水处理技术,填料的选择是滤池设计和影响出水水质的关键因素。
Under the same air-water ratio the performance of new polyurethane sponge BAF was better than biological granular ceramic BAF . ( 4 ) Characteristics of operation of the two BAFs and influence of backwashing on filter performances were discussed .
