Coagulation and Rapid Mixing

Typical coagulants and aids are discussed in further detail below: Chemicals commonly used for primary coagulants include aluminum or iron salts and organic polymers. The most common aluminum salt used for coagulation is aluminum sulfate, or alum. Alum may react in different ways to achieve coagulation. When used at relatively low doses (<5

Coagulants and flocculants fact sheet

reaction with water Alum (Aluminium sulfate) will form six hydrogen ions, Polyaluminium chloride (PAC) three hydrogen ions, and ACH a single ydrogen As such, Alum will tend to cause a more significant decrease in pH ( increase the acidity) than PAC or ACH. This reaction explains the effect these coagulants will have on water pH.

Water Treatment Coagulants Coagulant water treatment chemicals come in two main types – primary water treatment coagulants and coagulant aids. Primary coagulants neutralize the electrical charges of particles in the water which causes the particles to clump together. Chemically, coagulant water treatment chemicals are either metallic salts (such as alum) or polymers.

Flocculants and Coagulants | ChemTreat, Inc.

Inorganic coagulant treatment is particularly effective on raw water with low turbidity (total suspended solids concentration) and will often treat this type of water when organic coagulants cannot. Once added to water, inorganic coagulant chemicals react with the alkalinity and hydrate to form metal (aluminum or iron) hydroxide precipitates, which act as a sweepfloc mechanism.

 · By far, the most widely used inorganic polymer coagulants are iron and aluminum salts, such as polyferric chloride (PFC), polyferric sulfate (PFS) and polyaluminum chloride (PAC). To avoid the disadvantages and improve coagulation efficiency of iron and aluminum salts, a new composite coagulant, polyferric aluminum chloride (PFAC), has been developed ( Lan et al. 2009 ; .
