Poyerekeza ndi ma coagulants achikhalidwe, ACH (Aluminium Chlorohydrate) ili ndi izi:
● Kuyera kwambiri ndi chitsulo chochepa kumatha kukwaniritsa kupanga mapepala ndi zodzoladzola.
● Flocs imapanga mofulumira ndikukhazikika mofulumira, yomwe imakhala ndi mphamvu yochuluka yopangira kuposa mankhwala achikhalidwe.
● Maonekedwe a mankhwala a ufa ndi oyera, tinthu tating'onoting'ono timafanana, ndipo madzi ake ndi abwino.
● Njira yothetsera vutoli imakhala ndi turbidity yochepa komanso kukhazikika kwabwino.
● Mitundu yambiri ya PH imagwiritsidwa ntchito, kuyambira 5.0 mpaka 9.0.
● Mchere wochepa wotsalira wosungunuka ndi wopindulitsa posinthanitsa ndi ayoni komanso kupanga madzi oyeretsedwa kwambiri.
● Imatha kutha kutengera kusintha kwa matope, alkalinity, ndi zinthu zachilengedwe.
● Good flocculation zotsatira akhoza anakhalabe kwa kutentha otsika, otsika turbidity madzi khalidwe.
● Kuchuluka kwa zotsalira za aluminiyamu yaulere ndizochepa, ndipo khalidwe lamadzi pambuyo pa kuyeretsedwa limakwaniritsa zofunikira za dziko.
● Kuwonongeka ndi kochepa, ufa ndi wosavuta kusungunuka, kuposa zinthu zina zofanana.
