Nruas thickener ua hauj lwm nrog cov txheej txheem rotary nruas thickening kom tau txais cov ntsiab lus siab kho cov nyhuv.
Cov nqi ntawm thaj av, kev tsim kho thiab kev ua haujlwm tau txais kev cawmdim tag nrho vim tias lub tshuab no siv qhov chaw hauv pem teb tsawg dua nrog nws cov qauv yooj yim, me me flocculent yuav tsum thiab ua haujlwm tsis siv neeg.

Yog li ntawd, lub slurry yog thickened.Lub peev xwm ua haujlwm ntawm peb lub nruas sludge thickener tau txhim kho, thiab lub sijhawm ua haujlwm luv luv.Cov sludge sib cais tuaj yeem txo qhov hnyav ntawm txoj siv rau cov dej permeating.Lub caij no, pawg sludge yog tsim ua kom ruaj khov.Tsis muaj daim ntawv dej nyab los yog sab-dhau phenomenon yuav tshwm sim.Tom qab ntawd, lub cev qhuav dej ua kom zoo dua qub, thiab cov ntsiab lus dej tau qis dua.Tom qab sib cais, cov ntsiab lus ntawm cov dej dawb txawv ntawm 0.5 ‰ mus rau 1 ‰, uas zoo sib xws nrog ntau npaum li cas thiab hom polymer.

Lub semi-centrifugal teb nruas thickener tuaj yeem lim cov dej dawb los ntawm kev quab yuam sab nraud.Nws muaj cov kev xav tau siab rau cov khoom siv polymer thiab lub zog ntawm cov sludge.Nyob rau hauv kev sib piv nrog rau siv lub tshuab thickening, peb lub nruas teb sludge thickener tuaj yeem muab cov sludge thickened nrog cov dej qis dua.Cov sludge nrog nws cov ntsiab lus dej ntau dua 1.5% yog qhov kev xaiv zoo dua.
