WebIn water treatment, coagulation and flocculation involve the addition of compounds that promote the clumping of fine floc into larger floc so that they can be more easily separated from the water. Coagulation is a chemical process that involves neutralization of charge whereas flocculation is a physical process and does not involve neutralization of charge.
Webwater then heated to turn it into hydrated lime before use. When quicklime is mixed with water there is a potential for explosions due to the heat released from the chemical combinations. Lime also has reactions with alum and ferric sulfates so direct mixing should be avoided. Storage of these products should be in cool, dry places.
