L. Sultan Technikon, Durban, South Africa, 2001.Historically inorganic coagulants were the coagulants of choice for OAF treatment of potable water. Water treatment practitioners using OAF technology preferred ferric chloride, an inorganic coagulant. Ferric chloride formed light, floatable floes at relatively low flocculation intensities and detention times. The inorganic coagulant was also more forgiving during incidents of overdosing and raw water and pH variability205 penWater--Purification--Dissolved air flotationDrinking water--PurificationWater--Purification--CoagulationThesishttps://doi.org/10.51415/10321/2767
