Lub Evolution ntawm Seawater RO Membranes
Zaj dab neeg ntawm seawater RO membranes pib thaum xyoo 1960. Cov kws tshawb fawb Sidney Loeb thiab Srinivasa Sourirajan tau tsim thawj RO membrane nyob rau lub sijhawm no. Lawv cov kev ua haujlwm hauv av tau nthuav dav rau kev siv tshuab desalination, tso cai rau peb hloov dej hiav txwv mus rau hauv dej tshiab. Qhov tshwj xeeb tshaj yog, xyoo 1961, Asmeskas Thawj Tswj Hwm John F. Kennedy tau pom zoo rau dej hiav txwv desalination ua ib txoj haujlwm hauv lub tebchaws, pom nws qhov tseem ceeb rau cov cheeb tsam uas tsis muaj dej.
Alexander Zarchin, Israeli engineers, tsim cov txheej txheem thermal desalination ntau tshaj 60 xyoo dhau los. Kev tshoov siab los ntawm tus neeg tshawb nrhiav Arctic uas tau txais cov dej haus los ntawm cov dej khov yaj, Zarchin txoj haujlwm tshiab tau nthuav dav rau kev nce qib hauv kev siv tshuab desalination. Nws txoj kev koom nrog kev khov dej hiav txwv hauv lub tshuab nqus tsev, cia cov dej khov rau desalinate, thiab tom qab ntawd sau cov dej tshiab uas tau txais thaum tseem sau cov ntsev. Txij thaum ntawd los, desalination tau txuas ntxiv mus, muab cov kev daws teeb meem tseem ceeb rau kev txhim kho dej thoob ntiaj teb.
Rov qab osmosis yog ib txoj kev siv dav rau desalinating seawater. Nws suav nrog kev yuam dej los ntawm cov khoom siv semipermeable uas xaiv tso cai rau cov dej molecules kom dhau thaum thaiv cov ntsev thiab impurities. Cov dej purified yog sau rau ntawm ib sab ntawm daim nyias nyias, tawm hauv qab concentrated brine. RO tsim cov dej ntshiab tsis hais cov khoom noj cov ntsev ntsev. Nws tuaj yeem yog lub zog siv zog thiab yuav tsum muaj cov txheej txheem tseem ceeb. Tsis tas li ntawd, kev tuav cov tshuaj lom brine pov tseg yog ib qho nyuaj. Dej hiav txwv thiab dej qab ntsev heev. evaporation thiab tso dej tuaj yeem haus txog li 80 megawatt-teev ib megaliter ntawm cov dej tsim. Hauv Middle East, cov nroj tsuag feem ntau siv cov khoom siv hluav taws xob pov tseg los ntawm cov chaw tsim hluav taws xob uas nyob ib sab thiab pheej yig roj rau thermal desalination.
Seawater Reverse Osmosis (SWRO) yog txheej txheem desalination uas siv cov txheej txheem tshwj xeeb kom tshem tawm ntsev thiab impurities los ntawm dej hiav txwv. Cov membranes no tau siv los ua lag luam txij thaum xyoo 1970s. Tsis zoo li ib txwm desalination txoj kev uas yuav tsum tau kub los yog theem hloov, SWRO tso siab rau ntawm daim nyias nyias, ua rau nws muaj zog ntau dua.
Ceev nrooj mus rau hnub tam sim no, thiab peb pom HID Membrane Co., Ltd. nyob rau pem hauv ntej ntawm RO membrane manufacturing. Tsim los ntawm 2008, HID tau dhau los ua tus neeg tseem ceeb hauv kev lag luam, ob qho tib si hauv Suav teb thiab thoob ntiaj teb.
