Afilter has been designed to have a run length of 48 hr while operating at a filtration rate of 12 m/h. the design backwash rate is 40 m/h, backwash duration is 15 min, and filter-to-waste duration is 10 min. the plant operators decided to clean the filters more thoroughly and they backwash at a rate of 55 m/h for 25 min. as a result, ripening takes longer and the filter-to-waste duration is 50 min. calculate the ufrv, ubwv, ufwv, and recovery (a) as designed and (b) as operated. what is the percent increase in the volume of treated water lost as waste backwash water and filter-to-waste water?
