PAM yochiza Madzi
Mawu Oyamba
PAM (Polyacrylamide) ndi mtundu wa polima womwe umagwiritsidwa ntchito pazinthu zosiyanasiyana, kuphatikizapo kuyeretsa madzi.Polyacrylamide amagwiritsidwa ntchito ngati flocculant mu madzi mankhwala njira kusintha yokhazikika ya inaimitsidwa particles, kukhala kosavuta kulekanitsa zolimba ndi madzi.
Polyacrylamide (PAM) ndi polima pawiri ntchito m'munda wa mankhwala madzi.Zimabwera mumitundu yosiyanasiyana, kuphatikiza nonionic, cationic, ndi anionic.

Mapulogalamu
Floculant:Polyacrylamide nthawi zambiri ntchito ngati flocculant mu madzi mankhwala kuchotsa inaimitsidwa zolimba, particulate nkhani ndi colloids ndi condense iwo mu flocs zikuluzikulu kuti atsogolere wotsatira sedimentation kapena kusefera.Flocculation iyi imathandizira kumveketsa bwino kwamadzi komanso kuwonekera.
Precipitant enhancer:Polyacrylamide akhoza kupanga zovuta ndi ayoni zitsulo kumapangitsanso zotsatira za precipitant.Pochiza madzi otayira okhala ndi ayoni zitsulo, kugwiritsa ntchito polyacrylamide kumatha kusintha mpweya komanso kuchepetsa zomwe zili mumadzi otayira.
Antiscant:Mu njira yothetsera madzi, Polyacrylamide Angagwiritsidwenso ntchito ngati choletsa sikelo kuteteza makulitsidwe pamwamba pa mipope ndi zida.Imawongolera ion bwino yamadzi, imalepheretsa kusungunuka kwa zinthu zomwe zasungunuka m'madzi, komanso imachepetsa mapangidwe a sikelo.
Kusintha kwabwino kwa madzi:Polyacrylamide Angagwiritsidwenso ntchito kusintha madzi khalidwe nthawi zina, monga kuonjezera sedimentation mlingo wa zolimba inaimitsidwa m'madzi, kuchepetsa sludge mapangidwe, etc.
Kulimbitsa nthaka:Mu nthaka solidification ndi kusintha, Polyacrylamide angagwiritsidwe ntchito kusintha bata ndi dzimbiri kukana kwa nthaka, potero kusintha thupi katundu wa nthaka.
Kuyenera kudziŵika kuti mlingo wa Polyacrylamide ayenera mosamala ankalamulira pa ntchito kupewa mavuto pa chilengedwe.Kuonjezera apo, ntchito yeniyeniyo imadalira zofunikira zenizeni za mankhwala a madzi ndi makhalidwe abwino a madzi.
