PolyDADMAC, wanda cikakken sunansa shine polydimethyldiallylammonium chloride, polymer ce mai narkewar ruwa ta cationic wacce ake amfani da ita sosai a fagen kula da ruwa. Saboda girman cajin cationic ɗin sa na musamman da babban solubility na ruwa, PolyDADMAC ingantaccen coagulant ne wanda zai iya cire turbidity, launi da sauran ƙazanta a cikin ruwa yadda ya kamata. Koyaya, a aikace-aikace masu amfani, galibi ana amfani dashi azaman aflocculanta hade tare da sauran coagulant don kula da najasar masana'antu.
Halaye da tsarin aikin PolyDADMAC
PolyDADMAC cikin hanzari yana haɗawa da tara ƙwayoyin colloidal masu caji mara kyau da kuma dakatar da daskararru a cikin ruwa saboda yawan cajin cationic ɗin sa. Tsarin aikinsa ya dogara ne akan jan hankali na electrostatic, wanda ke sa waɗannan ƙananan barbashi su yi taruwa zuwa manyan barbashi, ta yadda za a iya cire su yadda ya kamata yayin hazo ko tacewa.
Tsarin flocculation na PolyDADMAC
Flocculation yana ɗaya daga cikin matakai a cikin tsarin coagulation. Yana nufin tsarin da
"kananan furannin alum" da aka kafa yayin aikin coagulation suna samar da flocs tare da manyan barbashi ta hanyar tallatawa, neutralization na lantarki, haɗawa da kamawa.
A cikin masana'antar kula da ruwa, adsorption da neutralization na lantarki ana rarraba su azaman coagulation, yayin da haɗin gwiwa da net- kama ana rarraba su azaman flocculation. Abubuwan da suka dace ana kiran su coagulants da flocculants bi da bi.
An yi imani da cewa PolyDADMAC yana da hanyoyin aiki guda uku: adsorption, neutralization na lantarki da haɗin gwiwa. Biyu na farko sune manyan. Shi ya sa aka kebe PolyDADMAC a matsayin coagulant. Koyaya, yawancin mutane suna ɗaukar coagulation da flocculation azaman tsari iri ɗaya, don haka PolyDADMAC kuma ana kiransa flocculant.
A cikin hanyoyin kula da ruwa, PolyDADMAC ana amfani dashi galibi azaman flocculant don haɓaka ingancin ruwa. Musamman, rukunin gishirin ammonium na cationic quaternary na PolyDADMAC na iya haifar da jan hankali na electrostatic tare da abubuwan dakatarwa na anionic ko barbashi na colloidal a cikin ruwa, wanda ke haifar da neutralization, kafa flocs na manyan barbashi da daidaita su. Ana duba waɗannan ɗumbin ɗumbin ruwa yayin aikin lalata ko aikin tacewa don tsarkake ingancin ruwa.
Amfanin PolyDADMAC
Idan aka kwatanta da flocculants na gargajiya (alum, PAC, da sauransu), PolyDADMAC yana da fa'idodi masu zuwa:
Ingantacciyar: PolyDADMAC na iya cire ƙazanta a cikin ruwa da sauri da haɓaka ingancin ruwa.
Sauƙi don aiki: Amfani da shi yana da sauƙi, kawai ƙara shi a ƙarƙashin yanayin da ya dace.
Dorewa: PolyDADMAC yana da kwanciyar hankali mai kyau kuma baya rushewa cikin sauƙi kamar polyacrylamide.
Ƙarfin flocculation mai ƙarfi: Ƙungiyar gishiri na cationic quaternary ammonium yana ba PDMDAAC ƙarfin flocculation mai ƙarfi, ta yadda ya dace da kula da halayen ruwa daban-daban;
Kyakkyawan juriya na gishiri, acid da juriya na alkali: PDMDAAC ya dace da yanayin ingancin ruwa mai rikitarwa, kuma har yanzu yana da ingantaccen aikin flocculation a ƙarƙashin babban salinity, acidic ko yanayin alkaline;
Low cost: PolyDADMAC yana da babban flocculation yadda ya dace da ƙananan sashi, wanda zai iya rage farashin maganin ruwa.
Low sludge: PolyDADMAC yana samar da ƙarancin sludge fiye da inorganic coagulant da flocculants kuma yana adana farashin sarrafawa.
PolyDADMAC sashi da matakan kariya
Lokacin amfani da PolyDADMAC, yakamata a bi hanyoyin aiki sosai don tabbatar da ingantaccen sakamako na jiyya da kuma guje wa yiwuwar illa. Yawancin lokaci, bayan ƙara flocculants kamar polyaluminium chloride, ana ƙara PolyDADMAC don cimma mafi kyawun tasirin coagulation. Bugu da kari, ya kamata a daidaita sashi daidai gwargwadon ingancin ruwa da buƙatun jiyya. Za'a iya tantance ma'aunin da ya dace ta gwaje-gwajen kwalba.
Gaba daya,PolyDADMACyana taka muhimmiyar rawa a fagen kula da ruwa. Zurfafa fahimtar kaddarorinsa da aikace-aikacensa zai taimaka don yin amfani da wannan samfurin yadda ya kamata don inganta ingancin ruwa da kare muhalli.
