Imininingwane yokusebenzisa i-Cation polyacrylamide
I-Cation polyacrylamide ingelinye lama-polyacrylamide amaningi, kodwa enkambisweni yokusebenzisa, abasebenzisi abaningi abaqondi ulwazi olufanele kanye nokusetshenziswa kwemikhiqizo yayo, ngakho-ke abakwazi ukuhlangabezana nezidingo zabasebenzisi, ngakho-ke ukuze basebenzise umkhiqizo kangcono, kuqaliswa izinyathelo zokuqapha zokusetshenziswa kwawo.
Okokuqala, naka ububanzi beqembu le-polyacrylamide flocculation
Ekusetshenzisweni kwangempela kokukhiqiza, uma ivolumu yesisindo se-flocculation incane, izothinta ukusebenza kahle kokukhipha amanzi, uma ububanzi besisindo se-flocculation bukhulu, kuzonciphisa izinga lokomisa lekhekhe lodaka, elizoba nokuqukethwe kwamanzi okuphezulu, kanti udaka olucindezelwe luzoqukatha amanzi amaningi. Ngakho-ke, kubalulekile ukukhetha isisindo sama-molecule se-polyacrylamide.
Okwesibili, qonda izici zodaka
Ngaphambi kokuthenga i-polyacrylamide, kufanele siqonde umthombo we-sludge kanye nesilinganiso sokuqukethwe kwezingxenye ezahlukene ze-sludge, ngokusho kokuhlaziywa kwedatha okuhambisanayo, ukuze siqonde ukuthi yiluphi uhlobo lwendlela yokwelapha okufanele isetshenziswe ezinhlotsheni ezahlukene ze-sludge, phakathi kwazo ukuhlukaniswa okuvamile kwe-sludge kuyinto ephilayo futhi engaphili.
Ngaphansi kwezimo ezivamile, wonke umuntu usebenzisa i-polyacrylamide ye-ion ene-precipitation positive ukwelapha udaka oluphilayo, ukwelashwa kwe-anionic PAM kokusebenza kahle kodaka olungaphili kuzoba phezulu, futhi izinga le-acid base lodaka nalo liyindinganiso yokubhekisela, lapho i-acidity inamandla kakhulu, khetha imikhiqizo ye-cationic.
Okwesithathu, amandla eqembu le-polyacrylamide flocculation
Kufanele futhi sinake amandla okugobhoza ekukhiqizweni nasekusetshenzisweni, futhi umgomo wokuhlola ukuthi ngeke uphuke ngaphansi kwezimo zesiqondiso esithile samandla. Ukukhethwa kwe-polyacrylamide ye-ionic esezingeni eliphezulu evuselelwe kungaqinisekisa ukuthi ukugobhoza kuzinzile, futhi ukukhethwa kwesakhiwo sama-molecule esifanele kanye nesisindo sama-molecule kuzothinta ukuzinza kokugobhoza.
Okwesine, izinga le-ionic le-polyacrylamide
Ngaphambi kokwelashwa kodaka, kumele siqale sichithe izidakamizwa ezinama-ionic degrees ahlukene elabhorethri ngokwesipiliyoni, singeze ngokulandelana amasampula odaka, ngokuya ngendlela izidakamizwa ezisabela ngayo kanye nodaka, ngokuqhathanisa, sikhethe imodeli efanele engabizi kakhulu, enganciphisa umthamo womkhiqizo wethu futhi inciphise kakhulu izindleko zethu zokwelashwa.
