A flocculant is typically used with a coagulant to generate larger particles. The flocculant pulls together the "pin floc" for faster settling in gravity clarifiers or rising in flotation clarifiers. Aries coagulants are used for a variety of process applications including: Raw water clarification.
Ferric Sulphate - Inorganic Primary Coagulant for Wastewater Treatment. Accepta 1450 is scientifically formulated for use in drinking water applications, wastewater treatment and effluent treatment. Accepta 1450 is effective over a wide pH range. Accepta 1450 can be used as an effective odour control agent and will aid phosphorus removal.

Iron(III) sulfate (or ferric sulfate), is the chemical compound with the formula Fe 2 (SO 4) 3. Usually yellow, it is a salt and soluble in water. A variety of hydrates are also known. Solutions are used in dyeing as a mordant, and as a coagulant for industrial wastes. It is also used in pigments, and in pickling baths for aluminum and steel.
Oct 18, 2017· Alum and ferric chloride are widely-used commodity coagulants. Many water treaters don't know that alternative, often more cost-effective, products exist.

Ferric sulphate is available as a commercial water treatment coagulant in the form of an anhydrous material that may be transported and stored in wooden barrels. The material will dissolve readily in a limited quantity of warm water so a special solution pot must be used with chemical feeders, in which 1 part ferric sulphate by volume is dissolved in 2 parts water to produce a solution of about 40% strength.
1) Ferric sulfate is superior as a coagulant, especially for co-precipitating other metals as hydroxides. "Not only do the Fe(III) cations as the positively charged basic salt ions neutralize the negative charge on finely dispersed precipitates, they also (in slight excess) act as flocculating agents.
