PALL lim caij thov teb:
--- Kev lag luam cua sov thiab lub zog nuclear: kev ua haujlwm ntawm cov roj rau roj turbines, boiler lubrication system, ceev tswj lub tshuab, bypass tswj cov tshuab, thiab purification ntawm pub dej twj, kiv cua thiab lub tshuab plua plav.
--- Kev lag luam hlau: siv rau qhov pom ntawm qhov hydraulic system ntawm dov mills thiab nruam casting tshuab thiab pom ntawm ntau cov khoom siv lubricating.
--- Cov khoom siv tshuab ua: lub tshuab ua kom tsis muaj dej thiab cov cua lim ntawm cov tshuab papermaking, cov tshuab tsuas, tshuab txhaj tshuaj thiab lub tshuab loj, tshuab ua hmoov av rov qab thiab lim cov tshuab ua luam yeeb thiab cov cuab yeej ua kom txau.
Hloov zaus:
Nyob ntawm cov khoom siv raw uas siv, cov kev pab lub neej ntawm lub taub lim yuav sib txawv. Nrog rau kev txuas ntxiv ntawm kev siv sijhawm, impurities hauv dej yuav thaiv lub lim lim, thiab lub tshuab ua kom cov pa roj carbon ntau yuav puv nrog adsorption. Feem ntau hais lus, PP lim khoom yuav tsum tau hloov nyob rau hauv 3 lub hlis, thaum lub tshuab txais carbon lim dej yuav tsum tau hloov nyob rau hauv 6 lub hlis. Txij li cov hollow fibers tsis tau ntxuav, lawv feem ntau tso rau sab tom qab kawg ntawm PP paj rwb thiab ua kom cov pa roj carbon rau kev siv, txwv tsis pub lawv feem ntau yuav txhaws. Lawv yuav tsum tau hloov tom qab 1-2 xyoos rau kom tsis muaj menyuam ntawm qhov kawg ntawm cov cuab yeej lim dej.
