Filter filtration speed
Suspension of solid particles, when the uniform size, filter filter pore smoother filtrate through the residue of velocity. Application of coagulant will fine particles to form larger clumps, helps to improve filtering speed.
For solid particles settlement speed fast of suspended liquid, application in filter media upper feeding of filter machine, makes filter direction and gravity direction consistent, rough particles first settlement, can reduced filter media and residue layer of jam; in difficult filter of suspended liquid (as colloidal) in the mix as diatomaceous earth, and expansion Pearl rock, more rough of solid particles, can makes residue layer became loose; filtrate stick degrees larger Shi, can heating suspended liquid to reduced stick degrees. These measures will accelerate the filtration rate.
