Emkhakheni wokunakekelwa kwechibi, ukuqinisekisa ukuthi amanzi acwebezelayo acwebezelayo kubaluleke kakhulu ukuze kube nokubhukuda okuphephile nokujabulisayo. Umdlali obalulekile ekufinyeleleni ikhwalithi ephezulu yamanzi echibini yilokhuI-Aluminium Sulfate, ikhemikhali ethola ukuthandwa ngenxa yezakhiwo zayo eziphawulekayo zokuhlanza amanzi.
Umlingo we-Aluminium Sulfate
I-aluminium sulfate, eyaziwa kakhulu ngokuthi i-alum, iyi-coagulant kanye ne-flocculant ehlukahlukene. Umsebenzi wayo oyinhloko ekunakekelweni kwechibi ukucacisa amanzi ngokususa ukungcola nokuthuthukisa ukuhlunga. Uma ingezwa echibini, i-aluminium sulfate ibhekana nokusabela kwamakhemikhali okwakha i-gelatinous precipitate. Lesi sici sibamba izinhlayiya ezincane, njengokungcola kanye ne-algae, okwenza kube lula ukuthi uhlelo lokuhlunga lwechibi luzibambe futhi luzisuse.
Ukuthuthukisa Ukucaca Kwamanzi Nokubonakala Kwawo
Esinye sezizathu eziyinhloko ezenza abanikazi bamachibi basebenzise i-aluminium sulfate yikhono layo lokuthuthukisa kakhulu ukucaca kwamanzi. Amanzi anamafu noma angcolile ayinkinga evamile emachibini, abangelwa yizinhlayiya ezilengayo eziphuma ohlelweni lokuhlunga. I-aluminium sulfate isebenza njenge-coagulant, okwenza lezi zinhlayiya ezincane zihlangane zibe yizinhlayiya ezinkulu, ezinobungani nokuhlunga. Le nqubo ithuthukisa ukusebenza kahle kohlelo lokuhlunga lwechibi, okuholela emanzini acwebezelayo acwebezelayo aheha ababhukudi.
Ukulawulwa Nokuvimbela Ulwelwe
Ukukhula kwe-algae kuyinto ekhathazayo njalo kubanikazi bamachibi, ikakhulukazi ezindaweni ezifudumele. I-aluminium sulfate idlala indima ebalulekile ekulawuleni i-algae ngokuqeda izakhamzimba ezikhuthaza ukukhula kwayo. Ngokuzibopha nama-phosphate emanzini, i-aluminium sulfate ivimbela ukutholakala kwalesi sakhamzimba esibalulekile se-algae, ivimbele ukwanda kwayo. Ukusetshenziswa njalo kwe-aluminium sulfate akugcini nje ngokulwa nezinkinga ze-algae ezikhona kodwa futhi kusebenza njengesinyathelo sokuvimbela, kugcina indawo yechibi ihlanzekile.
Ibhalansi ye-pH kanye neKhemistri Yamanzi
Ukugcina ibhalansi ye-pH efanele kubalulekile empilweni yonke yamanzi echibini. I-aluminium sulfate inegalelo kulesi sici sokugcinwa kwechibi ngokusebenza njengesiqinisi se-pH. Isimo sayo se-acidic sisiza ekulweni namazinga aphezulu e-pH, ukuqinisekisa ukuthi amanzi ahlala ngaphakathi kwebanga elifanele. Lokhu akugcini nje ngokuthuthukisa ikhwalithi yamanzi kodwa futhi kuvikela imishini yechibi ekugqwaleni okungenzeka.
Ekuphetheni, ukwengezwa kwe-aluminium sulfate emanzini echibi kuvela njengoshintsho olukhulu ekufuneni indawo yokubhukuda ehlanzekile nekhangayo. Kusukela ekuhlanzeni amanzi kuya ekulweni nolwelwe kanye nokuqinisa amazinga e-pH, izinzuzo zale khemikhali ziningi. Abanikazi bamachibi abafuna ukuphakamisa ulwazi lwabo lwechibi kanye nokubeka phambili ikhwalithi yamanzi bangaphendukela ku-aluminium sulfate njengomngane othembekile enkambisweni yabo yokulungisa. Valelisa emanzini anamafu bese ubingelela ichibi elikhanga ngokukhanga kwalo okucwebezelayo.
