Kev Kaw Kev Tsim Khoom? 4 Tus Neeg Ua Phem Ntawm Kev Lag Luam RO Membrane Fouling & Kev Kho Kom Zoo Tshaj Plaws

Kev tsim khoom lag luam vam khom ntau rau Cov txheej txheem rov qab Osmosis (RO) rau cov dej ntshiab, tsis tau li no cov kab ke no feem ntau raug kev cuam tshuam los ntawm lub sijhawm tsis tau xav txog thaum RO daim nyias nyias "jam." Qhov teeb meem tseem ceeb no yog daim nyias nyias fouling, ib qho txheej txheem uas cov khoom tsis xav tau sib sau ua ke ntawm qhov chaw ntawm daim nyias nyias, ua rau cov dej ntws tsawg dua (flux), txo qis kev tsis lees paub ntsev, thiab nce siab ntawm kev ua haujlwm - ib qho cim qhia tias koj lub kaw lus ua haujlwm hnyav dua li nws yuav tsum tau ua.

Kev nkag siab txog cov ua rau yog thawj kauj ruam mus rau ib qho kev daws teeb meem kawgPlaub qhov ua rau muaj kev puas tsuaj ntawm cov RO membrane hauv kev lag luam yog:

1. Kev Ua Kom Nto (Kev Ua Kom Tsis Muaj Organic)

Qhov no tshwm sim thaum cov ntsev ntxhia yaj, xws li calcium carbonate, magnesium sulfate, los yog barium sulfate, precipitate tawm ntawm cov dej pub thiab tso rau ntawm qhov chaw membrane, ua rau thaiv cov qhov hws. Nws yog qhov tshwj xeeb tshaj yog nrog dej tawv cov peev txheej thiab nws nyob ntawm seb cov tshuaj lom neeg dej thiab cov nqi rov qab los ntawm lub cev.

2. Kev Ua Phem Rau Cov Khoom Me Me / Colloidal

Ua los ntawm cov khoom khov uas raug tshem tawm zoo li av nplaum, av nplaum, xuab zeb zoo, thiab lwm yam khoom me me uas tsis yog biological. Cov ntaub ntawv no sib sau ua ke hauv cov channel pub thiab ntawm qhov chaw membrane, tsim ib txheej tuab uas txo cov dej ntws. Tsis txaus lossis ua haujlwm tsis zoo kev lim ua ntej yog tus pab txhawb nqa tseem ceeb ntawm no.

3. Kev ua kom cov khoom noj tsis huv

Feem ntau hais tias yog hom uas feem ntau thiab nyuaj tshaj plaws. Nws cuam tshuam txog kev loj hlob ntawm cov kab mob me me (cov kab mob, cov pwm, algae) ntawm qhov chaw ntawm daim nyias nyias, uas tom qab ntawd tso tawm ib txheej tiv thaiv, nplaum hu ua a daim ntawv biofilmCov txheej txheem zoo li gel no thaiv dej hla thiab nyuaj rau tshem tawm thaum twg tsim tau lawm.

4. Kev Ua Phem Organic

Qhov no hais txog kev sib sau ua ke ntawm cov organic matter (NOM) zoo li cov tshuaj humic, roj, thiab roj av. Cov organic compounds no feem ntau lo rau ntawm daim nyias nyias ntawm qhov chaw, ua rau cov qhov hws thiab txo qhov permeability, tshwj xeeb tshaj yog nyob rau hauv cov kab ke kho cov dej saum npoo lossis cov dej khib nyiab.

Kev daws teeb meem kawg: Kev tiv thaiv thiab cov khoom siv tshaj lij

Qhov kev daws teeb meem kawg yog siv ntau txoj hauv kev:

1. Kev kho mob ua ntej zoo tshaj plaws: Qhov no yog qhov twg 90% ntawm cov neeg ua yuam kev! Kev ntxuav tshuaj lom neeg ib leeg tsis tuaj yeem them rov qab rau qhov kev kho ua ntej tsis zoo. Cov kauj ruam zoo li kev lim dej, kev ntsuas tshuaj tua kab mob, thiab tej zaum ultrafiltration yog qhov tseem ceeb kom tshem tawm cov foulants feem ntau. ua ntej cov dej mus txog rau hauv RO membranes.
2. Kev Ntxuav Tshuaj: Ib txwm Kev Ntxuav Tshuaj Siv cov tshuaj ntxuav uas cov chaw tsim khoom pom zoo, uas tau tsim tshwj xeeb (acidic rau kev ua kom tawv tawv, alkaline rau organic/biofouling) yog qhov tseem ceeb heev rau kev rov qab ua haujlwm thaum pom muaj qhov tsis zoo.
3. Kev Ua Haujlwm Zoo: Kev saib xyuas cov yam ntxwv tseem ceeb (kev poob siab, dej ntws, kev tsis lees paub ntsev) thiab zam kev rov qab los ntau dhau lossis kev kaw ntev yog qhov tseem ceeb.

Tsom ntsoov rau Qhov Zoo: Lub Hom HID

Thaum xaiv cov membranes, qhov zoo yog qhov tseem ceeb rau kev ua haujlwm mus sij hawm ntev. HID Membrane Co., Ltd. (HID) yog ib lub chaw tsim khoom tseem ceeb uas tshwj xeeb hauv Reverse Osmosis (RO) membranes, nrog rau kev muaj nyob hauv ob qho tib si Suav teb thiab thoob ntiaj teb txij li xyoo 2008. Nyob hauv Zhenjiang, Suav teb, HID muab ntau yam khoom, suav nrog kev nyob hauv tsev, kev lag luam, thiab, qhov tseem ceeb tshaj plaws, Kev Lag Luam RO Membranes rau kev kho cov dej kais, dej brackish (BW series), thiab txawm tias dej hiav txwv (SW series).

HID paub txog kev tsom mus rau tsim daim nyias nyias, kev siv tshuab ua haujlwm, thiab kev tswj xyuas zoo, muab cov qauv txhim khu kev qha (xws li 8040 thiab 4040 series) siv rau ntau yam kev siv uas xav tau ntau, suav nrog cov chaw tsim hluav taws xob, kev ua zaub mov thiab dej haus, thiab kev tsim khoom siv hluav taws xob. Kev xaiv lub chaw tsim khoom txhim khu kev qha, tshwj xeeb zoo li HID pab kom ntseeg tau tias koj tab tom txhim kho cov membranes tsim nrog kev ruaj khov siab thiab tsawg dua qhov tsis zoo.
