Kodi Zopanga Zaukadaulo Zimalimbitsa Bwanji Madzi a Mchere Kumakina Amadzi Atsopano

97.5% ya madzi padziko lapansi ndi nyanja, ndi nyanjaMadzi Desalination amawonjezera ndi kulowetsa madzi opanda mchere. Ndi kupita patsogolo kwa mafakitale, vuto la kupezeka kwa madzi ndi kufunikira kwakula, ndipo kusowa kwa madzi abwino kwalepheretsa chitukuko cha anthu. Popeza kuti teknoloji yochotsera mchere wa brackish madzi sakhudzidwa ndi nyengo ndipo imatha kuonetsetsa kuti madzi azikhala okhazikika usana ndi usiku, lusoli lakhala njira yofunika kwambiri kuti mayiko a m'mphepete mwa nyanja apeze madzi opanda mchere.

1. Kodi madzi amchere achuluka bwanji pa chilengedwe?

Madzi amchere, omwe amatchulidwa kuti ndi madzi onyansa omwe ali ndi mchere wambiri woposa 1%, amapereka mavuto aakulu a mankhwala.Kutentha kwapamwamba kuposa madzi a m'nyanja kumawonjezera zoopsa zomwe zimagwirizanitsidwa ndi mankhwala owopsa, organic, ndi heavy metal, kupangitsa njira zochiritsira zosagwira ntchito. Kutuluka kwachindunji kumapangitsa kuti nthaka ikhale ndi mchere wambiri, kuipitsidwa ndi madzi opanda mchere, madzi a m'nyanja, ndi kuwonongeka kwa chilengedwe.Nkhaniyi imakhala yovuta kwambiri m'madera amchere achilengedwe monga Middle East ndi North Africa, kumene zochita za anthu zimawonjezera vutoli.

Gulf mayiko (Saudi Arabia, UAE, Kuwait, Qatar, Bahrain, Oman): Chilala chadzaoneni ndi kusowa kwa madzi abwino achilengedwe zakakamiza maikowa kudalira kwambiri kuchotsa mchere m’madzi a m’nyanja (kutulutsa madzi a m’nyanja ochuluka kwambiri), pamene kugwiritsira ntchito mopambanitsa kwa madzi apansi panthaka kwachititsa kuti madzi a m’nyanja alowe m’mwamba ndi kukwera m’mwamba kwa zigawo za madzi amchere; ulimi wothirira m'madera achipululu wakulitsanso mchere wambiri wa nthaka.

Egypt: Mtsinje wa Nile ndi gawo lalikulu laulimi, koma kuthirira kosakwanira komanso kusayenda bwino kwa madzi kwadzetsa mchere wambiri. Madera a m’mphepete mwa nyanja akuwopsezedwa ndi kuloŵerera kwa madzi a m’nyanja.

2.Technologies pokwaniritsa madzi amchere ku makina amadzi amchere

Tekinoloje yolekanitsa ma membrane:

Ukadaulo wamamembrane ndi njira yothandiza kwambiri yolekanitsira zida kutengera kukula kwake. Imasefa mchere wosungunuka ndi tizilombo toyambitsa matenda pamene imalola madzi kudutsa. Njirayi ndi yopindulitsa chifukwa chosavuta kugwiritsa ntchito, mphamvu zochepa zomwe zimafunikira mphamvu, kusowa kwa kuipitsidwa kwachiwiri, komanso kugwira ntchito pa kutentha kozungulira.

RO ndi njira yothamanga kwambiri ya RO:

RO ndi kupanikizika kwakukulu kwa RO kumagwiritsa ntchito mphamvu pamphepete mwa mchere wambiri wa madzi a brackish kuti athetse kusiyana kwa mphamvu ya osmotic ndikukakamiza mamolekyu a madzi kuti asunthe kuchokera kumbali ya mchere wambiri kupita ku mbali ya mchere wochepa kudzera mu membrane yosakanikirana. Kupyolera mu njirayi, solute imasungidwa kumbali ya mchere wambiri kuti ipangitse kuchuluka kwa brine, pamene zosungunulira zimasamutsidwa ku mbali ya mchere wochepa kuti apange Desalinated Madzi.

EDI (Electrodeionization Technology):

EDI imatanthawuza ukadaulo wolekanitsa wa membrane womwe mosankha komanso molunjika umasuntha ma ion opangidwa mu yankho mothandizidwa ndi gawo lamagetsi la DC. Iwo ali otsika mowa mphamvu ndi amphamvu kusinthasintha kusintha mchere zili yaiwisi madzi, ndipo makamaka oyenera desalination wa anaikira brine.

Ubwino wa madzi amchere pamakina amadzi amchere ndi chiyani?

Tekinoloje yolekanitsa ma membrane:

Kutulutsa kochezeka kwa chilengedwe komwe kumakhudza pang'ono zamoyo zam'madzi; zinthu zamtengo wapatali monga madzi oyeretsedwa, mchere wosaphika, bromine, ndi potaziyamu, kukulitsa kugwiritsa ntchito gwero; ndi applicability yotakata, osakhudzidwa ndi nyengo kapena chilengedwe, ndi ntchito yosavuta.

RO ndi matekinoloje apamwamba kwambiri a RO:

Kuchotsa madzi m'madzi ndi kutsekereza koyenera, kugwiritsa ntchito mphamvu zochepa komanso zofunikira pazida, kuchuluka kwamadzi obwezeretsanso madzi, ukadaulo wokhwima, kusinthasintha kwanthawi zonse, komanso makina apamwamba kwambiri.

EDI (electrodeionization):

otsika mphamvu mowa, amphamvu kusinthika kusintha yaiwisi madzi mchere, makamaka oyenera desalination wa anaikira brine.

4. Kugwiritsa ntchito zida za reverse osmosis

• Makampani opanga magetsi ndi magetsi otentha: konzani madzi oyera kwambiri kuti akwaniritse zofunikira za kuuma kwamadzi opopera ndi madzi ozizira.
• Electroplating steel industry: heavy metal kuchotsa mlingo kufika kuposa 97%.
• Makampani opanga zakudya ndi zakumwa: fyuluta ndi kuchitira madzi yaiwisi kuonetsetsa mkulu khalidwe kukonza chakudya.
• Makampani amigodi ya malasha: kumangirira zinthu zama mankhwala ndi zitsulo zolemera m'madzi a mgodi wa malasha kuti mukwaniritse kuyeretsa madzi ndikugwiritsanso ntchito madzi onyansa.
• Kuchotsa madzi a m'nyanja: yeretsani madzi am'nyanja kapena madzi amchere kuti apange madzi abwino akumwa kapena ogwiritsidwa ntchito m'mafakitale.

5. Kugwiritsa ntchito EDI Electrodeionization

Makampani opanga zamagetsi ndi semiconductor: Madzi amtundu wa Ultrapure (resistivity ≥18.2 MΩ·cm) mukupanga chip ndi LCD.

Makampani opanga mankhwala ndi biotechnology: kupanga madzi a jakisoni, zinthu zachilengedwe, chikhalidwe cha cell, madzi a labotale, ndi zina zambiri.

• Makampani a Chemical ndi petrochemical: madzi opangira zopangira ndi mankhwala abwino, kubwezeretsanso madzi kuti azizungulira machitidwe amadzi ozizira, etc.
• Kafukufuku wa Laboratory ndi Sayansi: madzi a zida zowunikira (monga HPLC, ICP-MS), kuyesa kolondola.
• Makampani a Photovoltaic: Madzi abwino kwambiri otsuka silicon wafer.

6.Mwalandiridwa kuti mukambirane za madzi amchere ku makina amadzi opanda mchere

XXY akuitanira moona mtima abwenzi apadziko lonse lapansi ndi mabungwe am'matauni kuti agwire ntchito limodzi kuti athane ndi zovuta zamadzi. Titha kupereka mayankho makonda pamitundu yosiyanasiyana yamadzi, kufananiza bwino madzi ndi zofunikira pamasamba. Kuti mugule zida zapamwamba za RO pamtengo wabwino kwambiri, chonde pitani ku https://www.envspro.com/ kuti mulandire nthawi yochepa.
