Polyamine PA ( EPI-DMA )
Polyamine ndi gulu lachilengedwe lomwe lili ndi magulu opitilira awiri amino. Ma Alkyl polyamines amapezeka mwachilengedwe, koma ena ndi opangidwa. Alkylpolyamines ndi opanda mtundu, hygroscopic, ndi madzi sungunuka. Pafupi ndi pH yopanda ndale, amakhala ngati zotumphukira za ammonium.
Polyamine ndi madzi cationic polima osiyanasiyana molekyulu zolemera amene amagwira ntchito efficiently ngati pulayimale coagulant ndi mlandu neutralization wothandizira mu madzi-olimba kulekana njira m'mafakitale osiyanasiyana. Amagwiritsidwa ntchito kwambiri popanga mitundu yosiyanasiyana yamabizinesi akumafakitale komanso kuchimbudzi.

PA imayikidwa mu ng'oma zapulasitiki
PA iyenera kusindikizidwa ndikusungidwa pamalo ouma ndi ozizira. Zilibe vuto, sizingapse ndi moto komanso siziphulika. Si mankhwala oopsa.
Akagwiritsidwa ntchito popangira madzi osiyanasiyana kapena madzi otayira, mlingowo umachokera ku turbidity ndi kuchuluka kwa madzi. Mlingo wotsika mtengo kwambiri umachokera pakuyesa. Malo a dosing ndi liwiro losakanikirana liyenera kuganiziridwa mosamala kuti zitsimikizire kuti mankhwalawa akhoza kusakanikirana mofanana ndi mankhwala ena omwe ali m'madzi ndipo flocs sangathe kusweka. Ndi bwino kumwa mankhwalawa mosalekeza.
1. Ikagwiritsidwa ntchito yokha, iyenera kuchepetsedwa mpaka 0.05% -0.5% (kutengera zolimba).
2. Akagwiritsidwa ntchito pochiza magwero osiyanasiyana a madzi kapena madzi oipa, mlingowo umachokera ku turbidity ndi kuchuluka kwa madzi. Mlingo wotsika mtengo kwambiri umachokera pakuyesa. Malo a dosing ndi liwiro losakanikirana liyenera kuganiziridwa mosamala kuti zitsimikizire kuti mankhwalawa akhoza kusakanikirana mofanana ndi mankhwala ena omwe ali m'madzi ndipo flocs sangathe kusweka.
3. Ndi bwino kumwa mankhwala mosalekeza.
