Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm thim rov qab osmosis seawater desalination system yog siv cov txheej txheem rov qab osmosis membrane sib cais, thiab daim nyias nyias nrog kev xaiv rau cov tshuaj permeated ua ib daim nyias nyias. Feem ntau, ib daim nyias nyias uas tuaj yeem tsuas permeate cov kuab tshuaj tab sis tsis yog cov kuab tshuaj yog suav tias yog ib qho zoo tagnrho semipermeable membrane.
Qhov loj ntawm osmotic siab nyob ntawm seb hom dope, thiab qhov concentration thiab kub muaj feem xyuam rau cov khoom ntawm semipermeable membrane. Yog hais tias lub siab ntau dua li osmotic siab yog siv rau ntawm cov concentrated tov sab, cov kuab tshuaj nyob rau hauv cov concentrated tov yuav ntws mus rau dilute tov, thiab cov ntws cov kev taw qhia ntawm cov kuab tshuaj no yog opposite rau tus thawj infiltration kev taw qhia. Cov txheej txheem no hu ua rov qab osmosis.
Qhov rov qab osmosis seawater desalination kho cov cuab yeej muaj cov yam ntxwv hauv qab no:
1. Cov cuab yeej muaj cov qauv compact, me me ntim thiab yooj yim installation.
2. Cov khoom siv kho mob seawater desalination yog ib qho yooj yim rau kev khiav lag luam thiab tswj, thiab nws yog ib qho yooj yim los tswj tsis muaj disassembly rau tu thiab tu.
3. Lub kaw lus tsis muaj qhov xav tau siab ntawm cov dej nkag hauv dej. Ntev npaum li cov dej hiav txwv ntawm qhov kub ib txwm nyob nruab nrab ntawm 5 degree thiab 45 degree tuaj yeem siv rau desalination, thiab cov khoom siv hauv hiav txwv feem ntau yog nruab nrog lub zog qis, lub ntsiab cav thiab lub cav ua haujlwm.
Lub pretreatment ntawm dej mov nyob rau hauv seawater desalination cov txheej txheem yog tus yuam sij kom ntseeg tau lub sij hawm ntev kev ruaj ntseg ntawm lub rov qab osmosis system. Thaum tsim cov phiaj xwm dej hiav txwv pretreatment, lub hav zoov ntawm cov kab mob loj, cov kab mob thiab cov algae thiab lwm yam impurities hauv dej hiav txwv yuav tsum tau txiav txim siab tag nrho. Kev loj hlob ntawm cov kab mob yuav tsis tsuas yog coj teeb meem ntau rau cov chaw siv dej, tab sis tseem cuam tshuam ncaj qha rau kev ua haujlwm ntawm cov khoom siv dej hiav txwv desalination thiab seawater desalination tej yaam num. Nyob rau lub caij ntuj sov thiab lub caij ntuj no qis, ntau cov sediment yog nkag mus rau hauv cov dej hiav txwv, thiab cov turbidity hloov zoo heev, uas yog ib qho yooj yim ua rau tsis ruaj tsis khov ntawm seawater pretreatment system. Cov dej hiav txwv muaj corrosive heev, yog li cov ntaub ntawv ntawm cov khoom siv, li qub, thiab cov yeeb nkab fittings siv nyob rau hauv lub system yuav tsum tau soj ntsuam xyuas kom zoo corrosion kuj.
