PDMDAAC (Polydimethyl diallyl ammonium chloride)

Polydimethyl diallyl ammonium chloride (PDMDAAC) ndi mankhwala ochizira madzi otsika mtengo komanso ogwira ntchito zosiyanasiyana omwe amatha kusintha zinthu zambiri zachikhalidwe m'njira zosiyanasiyana, zomwe zimapereka zabwino zazikulu monga kukweza khalidwe, kuchepetsa ndalama, komanso kugwira ntchito bwino. Imatha kusintha zinthu zopanda chilengedwe monga polyferric sulfate ndi polyaluminum chloride, komanso carbon yogwira ntchito, yokhala ndi gawo limodzi mwa magawo atatu okha a zinthu zachikhalidwe, zomwe zimapangitsa kuti mitundu ichuluke komanso kupanga matope pakati. Imatha kuchiza mitundu yosiyanasiyana ya madzi otayira utoto omwe amachotsedwa, zomwe zimachepetsa kwambiri ndalama zotayira matope.

Nthawi yomweyo, imatha kusintha PAM yachikhalidwe ya cationic, kupereka mitengo yotsika, kusungunuka bwino, komanso kugwira ntchito mosavuta pa cationionicity yomweyo. Kugwiritsa ntchito pamodzi kungachepetse ndalama zothandizira ndi 30%, ndipo kumatha kusintha kwathunthu zochitika zachikhalidwe zochotsera madzi a matope. Kuphatikiza apo, imatha kusintha ma coagulants amchere a aluminiyamu monga alum ndi polyaluminum sulfate, osakhudzidwa ndi kutentha kwa madzi, kupanga ma floc okhuthala, okhazikika mwachangu, kuthetsa mavuto a zotsalira za aluminiyamu, ndikukhazikitsa khalidwe la zinyalala.

Ikhozanso kuphatikizidwa ndi ufa wachitsulo kuti ilowe m'malo mwa laimu wokonza matope, popanda kuwonjezera kuchuluka kwa matope, kusasiya zinyalala, komanso kupangitsa kuti mankhwala oyambira asavutike. Ngakhale kuti matope ovuta amafunika zinthu zosakaniza, kugwiritsa ntchito bwino ndalama kumaposa kwambiri mankhwala achikhalidwe. Munthawi yomwe pali kuwongolera ndalama mozama komanso kufunafuna madzi otayirira okhazikika, PDMDAAC, yokhala ndi ubwino wambiri wa mlingo wochepa, kupanga matope ochepa, zotsatira zake zokhazikika, komanso kugwiritsa ntchito mosavuta, yakhala njira yabwino kwambiri yosinthira malo akuluakulu oyeretsera madzi ndi madzi kuti alowe m'malo mwa mankhwala achikhalidwe, zomwe zimapangitsa kuti madzi azigwiritsidwa ntchito bwino komanso kuti ndalama zichepetsedwe.
