Polyacrylamide wani nau'in farin kristal ne wanda ke buƙatar narkar da shi sosai don cimma sakamako mafi kyau. Yawancin masu amfani suna tunanin cewa tsawon lokacin narkar da lokacin motsa jiki shine mafi kyau, amma a zahiri wannan ba haka bane. Idan lokacin motsawa ya yi tsayi da yawa, zai haifar da raguwar sarkar kwayoyin halittar PAM kuma ya shafi aikin flocculation.

A matsayin ɗaya daga cikin mahimman alamun polyacrylamide, ionity yana nufin cajin ionic mara kyau da tabbatacce da ƙimar cajinsa. Mutane da yawa suna ba da hankali sosai ga ionity lokacin siye, suna tunanin cewa mafi girma shine mafi kyau. Amma a zahiri, matakin ionicity yana da alaƙa da girman nauyin kwayoyin halitta. Mafi girman ionity, ƙananan nauyin kwayoyin halitta, kuma mafi girma farashin. A cikin tsarin zaɓin, ban da ionity, wasu dalilai suna buƙatar la'akari da su, kamar ƙayyadaddun yanayin ingancin ruwa, buƙatun don tasirin flocculation, da dai sauransu.
