Yadda za a zabi flocculant da ya dace da ku a cikin maganin ruwa mai sharar gida

A cikin aikin gyaran ruwa, yana buƙatar bin matakai na aiki, kuma bayan an gwada shi don cika ma'auni, an sauke shi.A cikin wannan jerin matakai, flocculant yana taka muhimmiyar rawa.TheFlocculantiya flocculate da dakatar al'amarin na kananan kwayoyin a cikin ruwa.Tsayawa, yin sauƙi tace.Nau'in flocculant suma suna da wadata sosai.Yadda za a zabi flocculant wanda ya dace da ku yana da mahimmanci kuma yana da mahimmanci.Game da zaɓi na flocculants, masana'antun PAM da PAC suna da shawarwari masu zuwa:
