Izimiso nezindlela zokwelashwa kwamanzi angcolile akhiqizwa iphrofayili ye-aluminium yokwelashwa kwendawo

Amanzi angcolile akhiqizwa ngu Ukwelashwa kwephrofayili ye-aluminium ngokuyinhloko amanzi angcolile anesisekelo se-asidi, aqukethe inani elincane lama-anion ayingozi nama-cations afana ne-Ni2+, Sn2+, ne-F-. Indlela yokwelapha i-acid-base neutralization. Amanzi angcolile ngokuvamile ane-asidi futhi kufanele ancishiswe nge-alkali ukuze kulungiswe inani le-pH libe cishe ku-7-8.5. Ngesikhathi esifanayo, ngesikhathi senqubo yokungathathi hlangothi, ama-cations afana ne-Al3+, Ni2+, Sn2+, ne-Cr3+ wonke enza imvula ye-hydroxide. Amanzi angcolile angathathi hlangothi futhi anemvula ampontshelwa ku-coagulation ithangi ngepompo, futhi i-polyamide flocculant encibilikisiwe iphonswa emanzini angcolile ngepompo yobuningi ukuze ihlangane namanzi angcolile. Ngemuva kokuhlangana, amanzi angcolile angena ethangini le-sedimentation. Izindlela ze-sedimentation zihlanganisa indlela ye-sedimentation ye-plate ethambekele, indlela ye-air flotation, indlela ye-centrifugal sedimentation, njll. Umbhali ukholelwa ukuthi indlela ye-centrifugal sedimentation izinzile. Ngemva kokucwiliswa kwenhlabathi, uketshezi olucacile luyachichima lusuka embobeni yokuchichima ephezulu luphinde lungene echibini lokukhipha noma ukucubungula kabusha ithangi lokugcina amanzi.

 Ngemuva kokwelashwa okungenhla, amanzi angcolile angahlangabezana nezindinganiso zokukhishwa. Uma amanzi angcolile ezophinda asetshenziswe, amanzi angcolile angaphathwa ngokuhlunga okumahhadla bese efaka idivayisi ye-RO ukuze akhiphe ama-anion amaningi, ama-cations nezinto eziphilayo. Inani le-pH lamanzi lingase libe phansi ngalesi sikhathi, futhi lingalungiswa i-anion kanye nedivayisi yokushintshanisa i-cation ukuze lihlangabezane nezindinganiso zokuphinda zisetshenziswe. Udaka olukhiqizwa imvula luhlala lukhishelwa echibini le-sludge, futhi ngemva kokuphathwa ngomshini wokunyathelisa ikhekhe lepuleti noma i-belt dehydrator, luba insalela yemfucuza yezimboni futhi luthunyelwe endaweni yokuhlanza imfucumfucu yezimboni.
