Unyango lwamanzi lubaluleke kakhulu kwimveliso yemizi-mveliso yanamhlanje. Nangona kunjalo, ingxaki yefoam idla ngokuba yinto ephambili ekuthinteleni ukusebenza kakuhle kunye nomgangatho wonyango lwamanzi. Xa isebe lokhuseleko lokusingqongileyo libona ifoam eninzi kwaye lingahlangabezani nomgangatho wokukhupha amanzi, ukukhupha amanzi ngokuthe ngqo akupheleli nje ekucothiseni inkqubo, kodwa kunokubangela umonakalo onokubakho kwindalo esingqongileyo. Ukuze kusonjululwe le ngxaki, ukusetyenziswa kwe-defoamer kubaluleke kakhulu.
Iingozi zeFoam
Ukuphuphuma kwegwebu eligqithisileyo kumphezulu wesikhungo sonyango akuchaphazeli nje kuphela ukusebenza okuqhelekileyo kwesikhungo, kodwa kunokubangela ungcoliseko kwindawo engqongileyo. Ngokusebenzisa izicoci zokucoca, igwebu linokulawulwa ngokufanelekileyo ukukhusela ucoceko nokhuseleko lwendalo.
Ukuqokelelwa kwegwebu ngexesha lokungenisa umoya okanye ioksijini kunyango lwamanzi ebhayoloji kunokuphazamisa inkqubela yonyango kwaye kukhokelela ekulahlekelweni kodaka olusebenzayo kunye neebhaktheriya. Ukusetyenziswa kwee-defoamers kunokunciphisa ukuveliswa kwegwebu kwaye kuqinisekise inkqubela ethe tye kwinkqubo yonyango lwamanzi ebhayoloji.
Igwebu eligqithisileyo emanzini ajikelezayo alichaphazeli nje kuphela ukusetyenziswa kwesibini kwamanzi, kodwa linokuba nefuthe elithe ngqo kwinkqubela phambili yemveliso kunye nomgangatho wemveliso. Ukusetyenziswa kwezixhobo zokucoca amanzi kunokunciphisa igwebu emanzini ajikelezayo, kuqinisekisa umgangatho wamanzi kunye nokusebenza kakuhle kwemveliso.
Indlela yokukhetha i-defoamer
Umgaqo wokusebenza kwee-defoamers ngokuyintloko kukusebenzisana kweekhemikhali ne-surfactant kwi-foam, nto leyo enciphisa umsebenzi we-surfactant, ukuze kukhuthazwe ukuqhekeka kwe-foam. Enyanisweni, ezinye ii-defoamers zinokutshintsha nolwakhiwo lomphezulu we-foam okanye zinciphise ukuzinza kwe-foam ukuze kufezekiswe isiphumo sokuxovula. Ii-defoamers ngokungathandabuzekiyo zisisombululo esilungileyo xa zijongene nenani elikhulu leengxaki ze-foam.
Xa ukhetha iarhente yokuthintela ukubola, kufuneka uqwalasele nempembelelo yayo. Ezinye ii-defoam zinokuba neengxaki zokubola ezingaphelelanga okanye zesibini ze-foam, ezingenakukwazi nje ukusombulula ingxaki ye-foam, kodwa zinokuzisa neengxaki ezintsha. Kufuneka kuqatshelwe ukuba ezinye ii-defoam zinokuba yingozi kwiibhaktheriya zebhayoloji, zichaphazele inkqubo ye-MBR, kwaye zitshabalalise i-percolation membrane kwaye zivale i-ultrafiltration membrane. Emva kokongeza i-defoam, kufuneka uqwalasele nempembelelo yayo kwizalathisi zomgangatho wamanzi, njengexabiso le-pH, i-organic carbon iyonke, njl. Ukuba ezi mpawu zidlula umgangatho, zinokubangela ungcoliseko lwesibini kwaye zichaphazele impembelelo yonyango lwamanzi. Xa ukhetha iarhente yokuthintela ukubola, kufuneka uqinisekise ukuba ayizukubangela umonakalo kwinkqubo yonyango lwamanzi. Ke ngoko, iindleko kunye nokulula kokusebenza nazo zizinto ekufuneka ziqwalaselwe xa ukhetha ii-defoam.
Ukuba usenamathandabuzo malunga nokukhetha i-defoamer. Okanye ufuna ukuthenga i-defoamer kunye nezinye iikhemikhali zonyango lwamanzi. Nceda unxibelelane nam.
