I-PDMDAAC (i-Polydimethyl diallyl ammonium chloride)

I-Polydimethyl diallyl ammonium chloride (PDMDAAC) yiarhente yonyango lwamanzi engabizi kakhulu, esebenza ngeendlela ezininzi enokuthatha indawo yeearhente ezininzi zemveli kwiimeko ezahlukeneyo, inika iingenelo eziphambili ezifana nomgangatho ophuculweyo, iindleko eziphantsi, kunye nokusebenza kakuhle okwandisiweyo. Ingathatha indawo yeearhente zokususa umbala ezingaphiliyo ezifana ne-polyferric sulfate kunye ne-polyaluminum chloride, kunye ne-activated carbon, kunye nomthamo we-1/3 kuphela yeearhente zemveli, nto leyo ekhokelela kumazinga aphezulu okususa umbala kunye nemveliso yodaka encitshisiweyo. Inganyanga ngokufanelekileyo iintlobo ezahlukeneyo zamanzi amdaka edayi ephinda iguqulwe, inciphisa kakhulu iindleko zokulahla udaka.

Kwangaxeshanye, ingathatha indawo ye-PAM yesiqhelo ye-cationic, inika amaxabiso aphantsi, ukunyibilika okungcono, kunye nokusebenza okulula kwi-cationionicity efanayo. Ukusetyenziswa okudibeneyo kunokunciphisa iindleko ze-agent nge-30%, kwaye inokuthatha indawo ngokupheleleyo kwiimeko eziqhelekileyo zokukhupha amanzi odaka. Ngaphezu koko, ingathatha indawo ye-aluminium salt coagulants ezifana ne-alum kunye ne-polyaluminum sulfate, engachaphazeleki bubushushu bamanzi, ivelisa ii-flocs ezixineneyo, ezihlala ngokukhawuleza, isuse iingxaki ze-aluminium residue, kwaye izinzise umgangatho wokungcola.

Ingadityaniswa nomgubo wentsimbi ukuze ithathe indawo yelayimu yokulungisa udaka, ngaphandle kokunyusa umthamo wodaka, ingashiyi kungcola, kwaye ilula unyango olusezantsi. Nangona udaka oluntsonkothileyo lufuna iiarhente ezidityanisiweyo, ukusebenza kakuhle kweendleko kudlula kakhulu oko kweearhente zemveli. Kwimeko yangoku yokulawula iindleko ngokungqongqo kunye nokusukela ukungcola okuzinzileyo, iPDMDAAC, kunye neenzuzo zayo ezininzi zedosi ephantsi, imveliso yodaka ephantsi, iziphumo ezizinzileyo, kunye nokusebenza lula, iye yaba lukhetho olukhethwayo lokuphucula amashishini amakhulu okunyanga amanzi amdaka kunye namanzi ukuze athathe indawo yeearhente zemveli, nto leyo efezekisa ngokulula umgangatho wonyango lwamanzi ophuculweyo kunye neendleko ezincitshisiweyo.
