Particle Behavior in Deep-Bed Filtration: Part 1-Ripening and Breakthrough

摘要: Laboratory-scale filtration experiments were conducted using sedimentation basin effluent from a local lime-softening water treatment plant. Metals and synthetic organic chemicals are often adsorbed to particle surfaces. An electronic counter was used observe changes in the size distribution of filtrate as function filter depth time under variety operating conditions. The for an extended period (up 48 h) effects both ripening breakthrough over duration typical plant cycle. results indicate that not distinct stages but occur simultaneously different-size particles. media velocity investigated, simple normalizations developed.
