Factors affecting granular media filtration
WebBackwashing is a form of preventive maintenance so that the filter media can be reused. In water treatment plants, backwashing can be an automated process that is run by local programmable logic controllers (PLCs). The backwash cycle is triggered after a set time interval, when the filter effluent turbidity is greater than a treatment guideline ... WebFactors that affect granular media filtration include: a) Turbidity: The lower the turbidity in the filter influent, the longer the filter run and hence, better the performance. b) Media: The coarser the media, the less is the head loss, the longer is the run, and vice versa.
