摘要

Abstract

In this paper

a study to enhance the filtration for solid/liquid materials difficult to be filtered

such as highly viscous

highly compactible or gel like materials

is presented. Filter aids diatomaceous earth and wood pulp cellulose are used to enhance the filtration by improving filter cake structure and properties in the filtration of a biological health product and a highly viscous chemical fiber polymer melt product. The property of solid/liquid systems

filtration at different flow rates

specific cake resistance

cake wetness

filtration rate

filtrate turbidity for filter aid selection and evaluation

and operation optimization are investigated. The results are successfully applied to industrial process

and can be used as a reference for similar filtration applications.
