Kurapa nemvura chinhu chakakosha pakutarisira nharaunda, kuve nechokwadi chekuti mvura yakachengeteka kushandiswa uye kushandiswa mumaindasitiri. Chimwe chezvinhu zvakakosha mukuita uku kushandisa maflocculants—makemikari anokurudzira kuunganidzwa kwezvikamu zvakasungirirwa kuita mapoka makuru, kana kuti mafloc, ayo anogona kubviswa nyore nyore mumvura. Pakati pemhando dzakasiyana dzemaflocculants, maflocculants ecationic anonyanya kushanda nekuda kwekuchaja kwawo kwakanaka, uko kunosangana zvakanyanya nezvikamu zvine chaji isina kunaka zvinowanzowanikwa mumvura yakasviba. Chinyorwa chino chinoongorora maflocculants anonyanya kushandiswa pakurapa mvura uye mashandisirwo awo.
MaPolyacrylamides eCationic(CPAM)
MaCationic Polyacrylamides, ari pakati pemaflocculant anoshandiswa zvakanyanya muindasitiri yekurapa mvura. Kune vazhinji vashandisi, CPAM ndiyo sarudzo yavo iri nani. Mapolymer aya ane ma acrylamide subunits, ayo anogona kugadzirwa kuti asanganise mapoka anoshanda ecationic. Kugona kushandiswa kwemaCationic polyacrylamides kuri muhuremu hwawo hunogadziriswa hwemamorekuru uye huwandu hwechaji, zvichivabvumira kuti vagadziriswe kuti vakwanise kushandiswa. MaC-PAM anoshanda zvakanyanya mukurapa mvura yakasviba yemumaindasitiri uye kubviswa kwetsvina nekuda kwekushanda kwawo kwakanyanya kweflocculation uye zvinodiwa zvishoma zvedosi.
Poly(diallyldimethylammonium chloride) (PolyDADMAC)
PolyDADMAC imhando yeflocculant inoshandiswa zvakanyanya inozivikanwa nekuwanda kwayo uye kushanda kwayo zvakanaka mukurapa mvura. Iyi polymer inonyanya kushanda mukuita kwekubatanidza mvura neflocculation, zvichiita kuti ive sarudzo yakakurumbira yekurapa mvura yekunwa, mvura yakasviba, uye tsvina yemumaindasitiri. PolyDADMAC inoshanda zvakanaka pamwe chete nedzimwe flocculant necoagulants, ichivandudza maitiro ekurapa nekupa nzira yakasimba yekuunganidza nekubvisa zvidimbu.
Polyamines(PA)
Polyamines ndeimwe mhando ye cationic flocculants inowanzoshandiswa mukurapa mvura. Makemikoro aya, anosanganisira poly(dimethylamine-co-epichlorohydrin) nezvimwe zvakafanana, anoratidza simba rakasimba re cationic charge, zvichiita kuti ashande zvakanyanya mukuderedza zvidimbu zvakashaikwa zvisina kunaka. Polyamines anonyanya kubatsira mukucheneswa kwemvura isina kucheneswa, kubviswa kwezvinhu zvipenyu, uye kurapwa kwetsvina dzakasiyana-siyana dzemumaindasitiri. Kugona kwavo kugadzira dense flocs kunoita kuti nguva yekugadzikana ikurumidze uye kujeka kwemvura yakarapwa kuve nani.
Mashandisirwo uye Mabhenefiti
Maflocculant eCationic anoita basa rakakosha mukushandiswa kwakasiyana-siyana kwemvura, kubva pamvura yakasviba yemumaguta uye kuchenesa mvura yekunwa kusvika pakugadzirisa tsvina yemumaindasitiri. Chinhu chikuru chaanobatsira ndechekuti anogona kubvisa tsvina isina simba, zvichiita kuti floc iumbwe nekukurumidza uye zvakanaka. Izvi zvinoita kuti mvura ijekeswe zvakanaka, ideredzwe, uye iwedzere kunaka kwemvura. Pamusoro pezvo, maflocculant eCationic anowanzo shandiswa pamwe chete nemamwe makemikari ekurapa, akadai semacoagulant, kuti agadzirise maitiro ekurapa uye awane mwero wemhando yemvura inodiwa.
Kushandiswa kwe cationic flocculants kwakakosha mukurapa mvura kwemazuva ano, zvichipa mhinduro dzinoshanda uye dzakavimbika dzekuunganidza nekubvisa zvidimbu. Polyacrylamides, polyamines, PolyDADMAC ndedzimwe dze cationic flocculants dzinowanikwa mazuva ano. Kugona kwavo kushanda nesimba, kushanda nesimba, uye kuchinjika kunoita kuti zvive zvishandiso zvinokosha pakuona kuti mvura yakachena uye yakachengeteka inowanikwa mukushandiswa kwakasiyana-siyana.
Ehe, sarudzo ye flocculant inoenderanawo nemaitiro emushandisi ekushandisa, maumbirwo echinhu, nharaunda, nezvimwewo. Gwaro rekushandisa chigadzirwa rinofanira kuteverwa.
