Characteristic of a direct ffiltration system with dual media filters and cationic polyelectrolytes as sole coagulants is the formation off a filtration zone that moves down through the bed. The rate ...

Tangential flow filtration (TFF) is a useful method for separating molecules or particles in liquid solution by size and enables both concentration and the ability to change buffer composition. 1 TFF ...

Experiments indicate that direct filtration without sedimentation, when preceded by the use of coagulants and adequate flocculation time, can produce finished water turbidities and particle size ...
