i-pH yendle
Inani le-pH lendle linomthelela omkhulu emthonjeni we-flocculant. Inani le-pH lendle lihlobene nokukhethwa kwezinhlobo ze-flocculant, umthamo we-flocculant kanye nomphumela wokujiya kanye nokuthungwa. Uma inani le-pH likhona<4, umphumela wokujiya uphansi kakhulu. Uma inani le-pH liphakathi kuka-6.5 no-7.5, umphumela wokujiya uba ngcono. Ngemva kwenani le-pH >8, umphumela wokujiya uba mubi kakhulu futhi.
I-alkalinity endle inomthelela othile wokuvimba inani le-PH. Uma i-alkalinity yendle inganele, kufanele kufakwe i-lime namanye amakhemikhali ukuze ihambisane nayo. Uma inani le-pH lamanzi liphezulu, kuyadingeka ukwengeza i-asidi ukuze kulungiswe inani le-pH libe yi-neutral. Ngokuphambene nalokho, ama-polymer flocculant awathinteki kakhulu yi-pH.
izinga lokushisa lendle
Izinga lokushisa lendle lingathinta ijubane lokugeleza kwe-flocculant. Uma indle isezingeni lokushisa eliphansi, i-viscosity yamanzi iphezulu, futhi inani lokushayisana phakathi kwezinhlayiya ze-flocculant colloidal kanye nezinhlayiya zokungcola emanzini liyancishiswa, okuvimbela ukunamathelana kwe-floc; ngakho-ke, yize umthamo we-flocculant ukhuphukile, ukwakheka kwe-floc kusahamba kancane, futhi kukhululekile futhi kuncane, okwenza kube nzima ukukususa.
ukungcola endle
Ubukhulu obungalingani bezinhlayiya zokungcola endle buzuzisa ekugobhozeni, ngokuphambene nalokho, izinhlayiya ezincane nezifanayo zizoholela emphumeleni ongemuhle wokugobhoza. Ukuhlushwa okuphansi kakhulu kwezinhlayiya zokungcola kuvame ukuba yingozi ekugobhozeni. Ngalesi sikhathi, ukugobhoza inhlabathi noma ukwengeza izinsiza zokugobhoza kungathuthukisa umphumela wokugobhoza.
Izinhlobo ze-flocculants
Ukukhetha i-flocculant kuncike kakhulu ohlotsheni kanye nokuhlushwa kwezinto eziqinile ezilengayo emanzini angcolile. Uma izinto eziqinile ezilengayo emanzini angcolile zifana nejeli, kufanele kukhethwe ama-flocculant angaphili ukuze aphazamiseke futhi ajiye. Uma ama-floc amancane, kufanele kufakwe ama-polymer flocculant noma kusetshenziswe izinsiza zokuhlanganisa njengejeli ye-silica esebenzayo.
Ezimweni eziningi, ukusetshenziswa okuhlangene kwama-flocculant angaphili kanye nama-polymer flocculant kungathuthukisa kakhulu umphumela wokujiya futhi kwandise ububanzi bokusetshenziswa.
Isilinganiso se-flocculant
Uma usebenzisa i-coagulation ukwelapha noma yimaphi amanzi angcolile, kunezindlela zokuhlanza ezingcono kakhulu kanye nesilinganiso esingcono kakhulu, esivame ukunqunywa ngokuhlolwa. Isilinganiso esiningi kakhulu singabangela ukuzinza kabusha kwe-colloid.
Uchungechunge lokulinganisa lwe-flocculant
Uma kusetshenziswa ama-flocculant amaningi, ukulandelana kokulinganisa okufanele kudinga ukunqunywa ngokuhlolwa. Ngokuvamile, lapho kusetshenziswa ama-flocculant angaphili kanye nama-flocculant angaphili ndawonye, ama-flocculant angaphili kufanele afakwe kuqala, bese kufakwa ama-flocculant angaphili.
