Kuchotsa mchere ndi njira yochotsera mchere ndi zonyansa zina m'madzi a m'nyanja kuti zikhale zoyenera kumwa, kuthirira kapena kugwiritsa ntchito mafakitale. Izi ndizofunikira makamaka m'madera omwe madzi opanda mchere ali ochepa kapena osapezeka. Pali njira zosiyanasiyana zochotsera mchere, kuphatikizapo: Reverse Osmosis: Pochita izi, madzi a m'nyanja amadutsa m'kati mwa nembanemba yomwe imalola kuti mamolekyu amadzi okha adutse pamene akukana mchere ndi zonyansa zina. Madzi oyeretsedwa amasonkhanitsidwa ndipo brine yotayira imachotsedwa nthawi yomweyo. Multi-Stage Flash: Njirayi imaphatikizapo kutenthetsa madzi a m'nyanja mpaka aphwanyike, kenaka amaumitsa nthunzi kuti apange madzi akumwa. Gwiritsani ntchito evaporation yamitundu yambiri kuti muwonjezere kuchita bwino. Multiple Effect Distillation: Mofanana ndi multistage flash distillation, njirayi imaphatikizapo kugwiritsa ntchito magawo angapo kapena zotsatira zomwe madzi a m'nyanja amatenthedwa ndipo chifukwa chake nthunzi imafupikitsidwa kuti mupeze madzi atsopano. Electrodialysis: Mwa njira iyi, gawo lamagetsi limayikidwa pa mulu wa ma ion exchange membranes. Ma ion m'madzi a m'nyanja ndiye amachotsedwa ndi nembanemba kuti apange madzi abwino. Njirazi ndizogwiritsa ntchito mphamvu zambiri komanso zokwera mtengo, kotero kuphatikiza kwaukadaulo wogwiritsa ntchito mphamvu ndi mphamvu zongowonjezera nthawi zambiri zimagwiritsidwa ntchito kuti kuchotsa mchere kukhale kosatha. Kuchotsa mchere kuli ndi ubwino wake, monga kupereka gwero lodalirika la madzi aukhondo kumadera opanda madzi. Komabe, ilinso ndi zovuta zina, kuphatikiza kukwera mtengo, kuwononga chilengedwe chifukwa cha kutulutsa kwamadzi am'madzi komanso kuwononga moyo wam'madzi. Chifukwa chake, ndikofunikira kulingalira za kukhazikika komanso kukhudzidwa kwa chilengedwe pama projekiti akuluakulu ochotsa mchere.

YANTAI JIETONG ndi apadera pakupanga, kupanga makulidwe osiyanasiyana a makina ochotsera madzi am'nyanja kwazaka zopitilira 20. Akatswiri opanga ukadaulo amatha kupanga mapangidwe malinga ndi zomwe kasitomala amafuna komanso momwe tsamba lilili.

Yantai Jietong Water Treatment Technology Co., Ltd odziwika bwino mu mankhwala mafakitale madzi, madzi a m'nyanja desalination, electrolysis chlorine dongosolo, ndi zimbudzi mankhwala chomera, ndi latsopano mkulu-chatekinoloje ogwira ntchito kufunsira madzi chomera kufunsira, kafukufuku, chitukuko, kupanga ndi malonda. Tapeza zoposa 20 zopanga ndi zovomerezeka, ndipo takwaniritsa kuvomerezeka kwa kasamalidwe kabwino kachitidwe ka ISO9001-2015, kasamalidwe ka chilengedwe muyeso wa ISO14001-2015 ndi kasamalidwe kaumoyo ndi chitetezo pantchito muyeso OHSAS18001-2007.

Timatsatira cholinga cha "Sayansi ndi Ukadaulo monga chitsogozo, Ubwino Wopulumuka, Ngongole Yachitukuko", tapanga mitundu khumi ndi imodzi yamitundu 90 yamankhwala opangira madzi, ena mwa iwo amasankhidwa ngati zinthu zomwe zasankhidwa ndi PetroChina, SINOPEC ndi CAMC. Tapereka makina akuluakulu a electrolysis oteteza madzi a m'nyanja kuti asawonongeke ndi magetsi ku Cuba ndi Oman, ndipo tapereka makina a High Pure amadzi kuchokera kumadzi a m'nyanja ku Oman, omwe adapeza kuyamikira kwakukulu kuchokera kwa makasitomala athu ndi mtengo wampikisano ndi khalidwe. Ntchito zathu zoyeretsa madzi zatumizidwa padziko lonse lapansi, monga Korea, Iraq, Saudi Arabia, Kazakhstan, Nigeria, Chad, Suriname, Ukraine, India, Eritrea ndi mayiko ena.
