Yadda ake zaɓar flocculant da ya dace da ku a cikin maganin sharar gida

A cikin tsarin tsaftace ruwan shara, yana buƙatar yin jerin matakan aiki, kuma bayan an gwada shi don ya cika ƙa'idar fitar da ruwa, ana fitar da shi. A cikin wannan jerin hanyoyin, flocculant yana taka muhimmiyar rawa.Flocculantzai iya flocculant da aka dakatar da ƙananan ƙwayoyin halitta a cikin ruwa. Yana daidaita, yana sauƙaƙa tacewa. Nau'ikan flocculants suma suna da wadata sosai. Yadda ake zaɓar flocculant ɗin da ya dace da ku shima yana da mahimmanci kuma yana da mahimmanci. Dangane da zaɓin flocculants, masana'antun PAM da PAC suna da shawarwari masu zuwa:

Ya kamata a zaɓi yadda ake zaɓar mai zubar da shara a cikin ruwan shara bisa ga halayen ruwan shara a wata masana'anta ta musamman. A lokaci guda, ya kuma dogara ne akan inda aka ƙara mai zubar da shara da kuma abin da ake amfani da shi. Gabaɗaya, lokacin zabar mai zubar da shara mara ruwa, ya kamata a yi la'akari da abun da ke cikin ruwan shara, sannan a zaɓi wanda ya dace (gishirin ƙarfe, gishirin aluminum ko gishirin ƙarfe-aluminum, gishirin silicon-aluminum, gishirin silicon-ferric, da sauransu); masu zubar da shara mara ruwa mara ruwa sun haɗa da:polyaluminum chloride (PAC), polyaluminum sulfate (PAS), polyaluminum sulfochloride (PACS) kumaPolyferric sulfate (PFS), da sauransu. Daga cikinsu, PAC da PAS da suka fi wakiltar suna da halaye na daidaitawa mai kyau ga canje-canje a cikin ingancin ruwa da aka yi wa magani ta hanyar sinadarai masu sarrafa ruwa, tasirin coagulation mai kyau da tsarkakewa, da ƙarancin farashin sinadarai.

Lokacin zabar wani abu mai kama da organic flocculant (kamar:polyacrylamide PAM), ya dogara ne akan ko ana amfani da anionic polyacrylamide, cationic polyacrylamide ko nonionic polyacrylamide. Anionic polyacrylamides an gina su ne akan matakin hydrolysis. Zabin cations yawanci ana amfani da su wajen cire ruwa daga laka. Zabin cationic polyacrylamide yana da matukar muhimmanci. Cibiyoyin kula da najasa na birane galibi suna amfani da polyacrylamide mai matsakaicin ƙarfi na cationic. Ana amfani da cations masu rauni gabaɗaya don bushewar laka a masana'antar yin takarda da bugawa da rini, kuma galibi ana amfani da ruwan sharar magunguna. Zaɓi cations masu ƙarfi da sauransu. Kowace nau'in ruwan sharar gida tana da nata halaye. Ana amfani da polyacrylamide mara ionic galibi a ƙarƙashin yanayin acidic mai rauni, kuma galibi ana amfani da PAM mara ionic a masana'antar bugawa da rini.

Masu samar da maganin ruwabayar da shawarar cewa ya kamata a tantance zaɓin duk waɗannan flocculants bisa ga gwajin. A cikin gwajin, a ƙayyade kimanin adadin allurai, a lura da saurin flocculation da sedimentation, a ƙididdige farashin magani, sannan a zaɓi wani wakili mai flocculation mai araha da dacewa.
