Rapid Gravity and Pressure Filters

-

Rapid Gravity and Pressure Filters:

The process of in-depth granular media filtration can be done under pressure (pressure filtration) or under gravity (rapid gravity filtration). Although, in both the processes ( pressure filtration and rapid gravity filtration), the basic mechanism and concept of removal of suspended particles are the same. However, having the same mechanism, there are some differences in both processes like notable distribution of flow between filters, hydraulic and control of flow through individual filters. (далее…)
