Ukadaulo waukadaulo wa membrane wamadzi

Ukadaulo waukadaulo wa membrane wamadzi (ultrafiltration, nanofiltration, reverse osmosis) umapereka kusanthula mozama za zabwino ndi zovuta zake.

Zochita zonse za anthu zimamangiriridwa mwamphamvu ndi madzi. Pamene chiŵerengero cha anthu padziko lonse chikukula, momwemonso kuchuluka kwa madzi oipa amene amapangidwa m’magawo a m’nyumba, m’mafakitale, ndi aulimi akuchulukanso. Tsoka ilo, madzi opanda mchere ali ndi malire ndipo sawonjezeredwanso mokwanira kuti akwaniritse zomwe zikuchulukirachulukira. Kusiyanitsa kumeneku kwadzetsa kugawidwa kosafanana ndi mpikisano waukulu wa madzi opanda mchere ochepa padziko lonse lapansi. Anthu mamiliyoni ambiri alibe madzi abwino akumwa, ndipo ntchito zaulimi zikuchepa chifukwa cha kusowa kwa madzi.

(RO, Reverse Osmosis system)

Reverse Osmosis (RO):

Ubwino:

u RO imachotsa pafupifupi zinthu zonse zosungunuka, kuphatikizapo tizilombo toyambitsa matenda.

u Ndiwothandiza kuchotsa mchere woipa monga mchere ndi mtovu.

u RO nembanemba angagwiritsidwe ntchito desalination.

Zoyipa:

u RO imachotsanso mchere wathanzi monga calcium ndi magnesium.

u Zimagwira ntchito pazovuta zapamwamba, zomwe zimapangitsa kuti pakhale mphamvu zowonjezera mphamvu.

u RO membranes amatha kuipitsidwa ndipo amafunikira kukonzedwa.

(Ultra Filtration System)

Ultrafiltration (UF):

Ubwino:

UF imagwira ntchito pochotsa zolimba zoyimitsidwa, mabakiteriya, ndi mamolekyu akulu.

u Zimagwira ntchito pazovuta zochepa poyerekeza ndi RO, zomwe zimapangitsa kuti pakhale ndalama zosungira mphamvu.

Ma membrane a UF ndi olimba komanso amakhala ndi moyo wautali.

Zoyipa:

UF sichimachotsa mankhwala osungunuka kapena ayoni.

u Zitha kufunikira chithandizo chisanachitike kuti mupewe kuipitsidwa.

u Kukula kwa pore kwa nembanemba ya UF kumatha kusiyanasiyana, kukhudza kusankha kwawo.

(Nanofiltration system)

Nanofiltration (NF):

Ubwino:

u NF imachotsa bwino zonyansa, zinyalala, ndi utsi wamankhwala.

u Ikhoza kusankha kuchotsa ma ion a divalent ndikulola ma ion monovalent kudutsa.

Ma membrane a NF ali ndi chiwopsezo chokwera kwambiri poyerekeza ndi RO.

Zoyipa:

u NF sichimachotsa mankhwala osungunuka kwathunthu.

u Zingafunikebe chithandizo chisanadze.

Mavuto ena amalepheretsa kufalikira kwaukadaulo wa NF.

Mwachidule, pomwe RO imapambana pakuchotsa zonyansa ndikuchotsa mchere, UF imapereka kutsika mtengo, kusinthasintha, komanso kusungidwa kwa mchere wopindulitsa. Kusankha pakati pa ziwirizi kumadalira zofunikira zenizeni zoyeretsera madzi ndi zofunikira.

Chifukwa chiyani tiyenera kulimbikitsa chitukuko chaukadaulo wa reverse osmosis:

Kusowa kwa Madzi: Pafupifupi anthu mabiliyoni anayi, pafupifupi magawo awiri mwa atatu alionse a anthu padziko lapansi, akukumana ndi kusowa kwa madzi kwa mwezi umodzi chaka chilichonse. Tekinoloje ya RO ingathandize kuthana ndi vutoli, makamaka m'madera ouma ndi zilumba.

Kuchotsa mchere m'madzi a m'nyanja: Reverse osmosis imagwira ntchito yofunika kwambiri pakuchotsa mchere m'madzi a m'nyanja. Kupyolera mu RO, titha kusintha madzi a m'nyanja kukhala madzi abwino amchere, kukwaniritsa zosowa za tsiku ndi tsiku za anthu. Kupitilira matani biliyoni 110 amadzi am'nyanja asinthidwa kale kukhala madzi opanda mchere pogwiritsa ntchito reverse osmosis, kupindulitsa anthu pafupifupi 320 miliyoni.

Wosamalira zachilengedwe: Poyerekeza ndi njira zachikhalidwe zochizira mankhwala, reverse osmosis imafuna zowonjezera zamankhwala zochepa ndipo sizitulutsa zinyalala zowononga zidulo kapena ma alkalis. Izi zimathandiza kuchepetsa kuwonongeka kwa chilengedwe.

Kugwiritsa Ntchito Mphamvu Zochepa: Njira ya reverse osmosis imadalira kokha kukakamiza monga mphamvu yoyendetsa, zomwe zimapangitsa kuti mphamvu ziwonongeke poyerekeza ndi njira zina zambiri zothandizira. Izi ndizofunikira kwambiri pachitukuko chokhazikika.

Global Cooperation: Madzi ndi tsogolo lathu logawana, ndipo mgwirizano wapadziko lonse ndi wofunikira kuti tigawane moyenera komanso kusamalira bwino chuma chamtengo wapatalichi.

Anthu mabiliyoni anayi, omwe ndi pafupifupi magawo awiri pa atatu aliwonse a anthu padziko lapansi, amasoŵa kwambiri madzi kwa mwezi umodzi chaka chilichonse. Komanso, anthu oposa 2 biliyoni amakhala m’mayiko amene madzi alibe madzi okwanira.

Ndizodabwitsa kuzindikira kuti theka la anthu padziko lapansi angakhale akukhala m'madera omwe akusowa madzi pofika chaka cha 2025. Chiwopsezo choyandikira cha vuto la madzi padziko lonse chimafuna chisamaliro chachangu ndi mgwirizano wapadziko lonse.

Monga katswiri wopanga zinthu za nembanemba ku China, HID yadzipereka kupanga payokha ndikupanga zotsogola zapamwamba za polyamide composite reverse osmosis nembanemba. Sikuti iwo paokha kukhala lathunthu kudula, anagubuduza, kuyezetsa, ma CD zida ndi mizere basi kwathunthu msonkhano, iwo anafikanso mlingo pamwamba mawu a zipangizo, zipangizo kupanga, luso kupanga ndi khalidwe chomaliza mankhwala.

Mndandanda wa HID-ROFS ndi imodzi mwa mapepala apamwamba omwe adapanga pogwiritsa ntchito zipangizo zamakono. Nembanemba iyi ya polyamide ili ndi kuthekera kolekanitsa kwa nembanemba ndipo imatha kuthana bwino ndi mchere wonse womwe wasungunuka ndi zinthu zamoyo zolemera kwambiri kuposa 100, ndikulola kuti mamolekyu amadzi adutse. Makamaka oyenera desalination mankhwala a madzi magwero mchere zili pansipa za 2000ppm

Kuthandizira chitukuko cha HID brand reverse osmosis membranes kumathandizira kulimbikitsa kugwiritsa ntchito madzi mosasunthika ndikukwaniritsa kufunikira kwa madzi abwino padziko lonse lapansi.
