O in a granular form was used as coagulant and it was applied in samples in liquid form this is why its preparation was necessary at a concentration of 5000 mgL in which 1ml applied on a sample of 500 ml represents a concentration of 10 mg L

Ferric sulfate is the more commonly used but ferrous sulfate is typically used in applications where a reducing agent or excess soluble iron ions are required Ferric Chloride Ferric chloride is generally the least expensive inorganic coagulant because it is generated as a waste material from steelmaking operations waste “pickle liquor”

When aluminium sulfate a common coagulating agent is used for water treatment it creates byproducts in the form of aluminium residuals In the process of coagulation it is beneficial to minimise the amount of aluminium residuals produced by aluminium sulfate

Aluminum Sulfate Alum Al2SO43 Alum is the coagulant of choice for many industrial and sanitary wastewater treatment applications due to its high efficiency effectiveness in clarification and utility as a sludge dewatering agent

After coagulation aluminum sulfate acts a flocculating agent and enables these particles to stick together and form bigger particles allowing easier purification of the water through sedimentation and filtration The use of aluminum as coagulants often results in higher levels of aluminum in the water but usually at safe amounts
