Ferrous sulfate, commonly known as green vitriol, is a sulfate of iron consisting of sky-blue or green monoclinic crystals or crystalline powder, with a relative density of 1.8987 and melting point of 64 °C; it is odorless and convergent and weathers when exposed to air, with the surface turning into a white powder; it is subject to oxidization in moist air, with a brown ferric subsulfate appearing on the surface; it is water glycerol soluble and insoluble in alcohol; ferrous sulfate is reductive and turns from a heptahydrate into a tetrahydrate at 56.6°C, and into a monohydrate at 64.6°C; it loses six crystal water molecules at 90°C, and all the crystal water molecules at 300°C, and decomposes to give off SO2 and SO3 in red hot state; it is also corrosive and fluoresces in dry air; its anhydride form is a white powder, which turns blue-green when reacting with water.

Polyacrylamide is a white powder or small particle substance.Chinese alias: flocculant, English name;PAM (acrylamide)
PAM is a kind of linear polymer, the products are mainly divided into dry powder and colloidal form.According to its average molecular weight, it can be divided into three types: low molecular weight (<1 million), medium molecular weight (2-4 million) and high molecular weight (>.7 million).According to its structure, it can be divided into four types: non-ionic type, anionic type, cation type and amphoteric type.

Polyaluminium ferric chloride, or PAFC for short, is an inorganic polymer coagulant formed by the coagulation and hydrolysis of aluminum salt and iron salt.Hydrolysis is fast and hydration is weak.Alum flowers formed dense, sedimentation rate fast.It is less affected by the change of water temperature and can meet the requirement of shearing force during flow.It can effectively remove the aluminum ions in the raw water and the residual free aluminum ions in the water after aluminum salt coagulation.
