phosphorus has been removed more from water in purification process can result
in higher grade of biological stability of the effluent tap water, especially
for the water plant when using surface water source. This study conducted the
experiments of phosphorus removal by three coagulants including aluminum
chloride, aluminum sulfate and poly aluminum chloride. The results indicated
that the poly aluminum chloride is the preferred one that could remove
phosphorus up to 80%, followed by aluminum chloride and aluminum sulfate. The
lowest proportion of aluminum quality to phosphorus quality is 63 as using poly
aluminum chloride, followed by aluminum chloride and aluminum sulfate. It is
suggested that the poly aluminum chloride should be the best option to remove
phosphorus in water plant.
