Kufotokozera
Kugwiritsa ntchito njira yoyeretsera madzi m'madzi otayira m'malo oyeretsera mpweya wachilengedwe kuyenera kufufuzidwa pamodzi ndi chithunzi cha Na2SO4-NaCl-H2O. Kuyeretsera madzi m'madzi otayira sikuti ndi njira yokhayo yolekanitsira mchere ndi madzi, komanso kungaphatikizepo makhalidwe osungunuka a mchere uliwonse wosapangidwa kuti ulekanitse mchere wosapangidwa bwino pang'onopang'ono mu dongosolo loyeretsera madzi m'madzi otayira. Mothandizidwa ndi njira yofanana, ukadaulowu ungagwiritsidwe ntchito osati poyeretsera madzi otayira m'malo oyeretsera, komanso m'madzi a gasi, m'madzi amchere pansi pa nthaka, m'madzi amchere ndi m'madzi otayira okhala ndi mchere wosiyanasiyana wosapangidwa. Poganizira za kulekanitsa madzi amchere, kulekanitsa mchere wamchere kumatha kuchitika. Mchere wosapangidwa wosapangidwa ukhoza kugwiritsidwanso ntchito malinga ndi mtundu wa kulekanitsa, kapena kugwiritsidwa ntchito ngati zinthu zopangira mankhwala, kapena ngati mchere woweta ziweto, womwe sungathe kungotulutsa madzi otayira otsiriza, komanso umathandizanso kubwezeretsanso zinthu zosiyanasiyana zofunika.
Madzi otayira ochokera ku fakitale yoyeretsera amayamba kulowa mu chipinda choyeretsera membrane cha RO. Pambuyo pa kuchuluka kwa membrane kwa magawo awiri, madzi atsopano amagwiritsidwanso ntchito. Madzi okhuthala amalowa mu dziwe losungunuka ndikulowa mu dongosolo losungunuka la crystallization kudzera mu pampu yodyetsa. Mu dongosolo losungunuka la crystallization, chifukwa cha kusungunuka kosiyanasiyana kwa Na2SO4 ndi NaCI, madzi akatuluka, madzi opangidwawo amawonjezeredwa, ndipo Na2SO4 imapangidwa mwapadera ndikupanga slurry ya nitrate. Slurry ya nitrate imalowa mu dongosolo losungunuka la centrifugal kudzera mu pampu yosungunuka. Pambuyo polekanitsa madzi olimba, mowa wa centrifugal umabwerera ku dongosolo losungunuka la crystallization, ndipo mchere wolimba umagulitsidwa ngati mchere wa mafakitale. Ndi kusungunuka, COD m'madzi osaphika imachulukitsidwa ndi kuchepa kwa madzi, zomwe zimapangitsa kuti madzi odyetsa achuluke mu thanki yosungunuka ndipo zimakhudza kwambiri kusungunuka kwa mchere mu njira yosungunuka.
Zipangizo zodyetsera za skid yotulutsa madzi kuchokera ku chipangizo cha electrodialysis chapamwamba, ndipo mphamvu yogwiritsira ntchito skid ndi 300m3/d. Nthawi yopangira pachaka ndi maola 8000.
Zipangizo zazikulu: skid yolumikizira njira, compressor skid, skid yosungiramo ma hydrocarbon osakanikirana, chida ndi chipangizo chowongolera.
