Viscosity direct or indirect with dv/dt

Ideally filter material?خوائصه

منو المواد filter media تتعقم autoclave

منو المواد filter media نستخدمها liquid

اكو اسئلة دزوها مهمة انزلها لو عدكم

Centrifugal filtration used for very fine particles

Most type of filtration effective for drying cake → less residual moisture from other types

Widely used to separate granular from liquor

Less effective for concentration slurries containing smaller particles

Filter press for multistage filtration by single press

Gravity filtration

Funnel filtration most common uesd

suction filtration

Conical funnel + buncher funnel usually used

Sterile filtration should be final step

Sterile filtration should used only pressure filtration ✅
Not vacuum ❌

Selectivity and retentive of memberane are charctrized by it's molecular weight cut off

Integrity test is non destructive

Bubble point and diffusion rate is function of porosity

Bubble point test direct measure of largest pore
Used to know if filter members is effective or no ( improper assembly)
