BLINDING

Blinding occurs as a build-up of particles in a filter medium, that prevents fluids from flowing through. It usually is viewed as a liquid filtration that has differing functioning between a used filter medium and a newer kind. As the filter medium operates then it begins to decrease in efficiency and will eventually require washing, rinsing, and even replacement. There are several potential reasons for this need, such as the persistence of blocking within the filter pores by trapped sediments and particles. This entire process is alluded to blinding and has the effect of reducing the flow rate while increasing the filter medium resistance.
