upflow filter
based on the theory of "inverse particle size" filtration, upflow filter is a new type of particle filter developed by shenzhen qingquan, which has absorbed the advantages of flap filter and v-type filter. it solves the problems of incomplete backwash and easy hardening of filter materials in the traditional upflow filter, and has been widely used in the field of water supply treatment.

★high filtration speed (8-12m/h), small area
★ strong filter capacity (greater than 15kg/m3), not easy to be blocked
★ small head loss, generally 0.6~0.8m
★ long filtration cycle, generally 36-72h
★ less backwash water consumption, less than 1.5%
★ good water quality, up to 0.3 ntu
★ simple structure, convenient construction, investment province
★ filter surface is filtered water, clean and beautiful
the “design rules for upstream flow filters” has been reviewed by the urban water supply and drainage professional committee of the china engineering construction standardization association and has been approved for publication. the serial number is cecs451: 2016, which will come into effect on january 1, 2017.
