Polyaluminium Ferrous Chloride,PAFC, as a kind of inorganic compound polymer, coordinates polymeric Fe on the basis of polyaluminium chloride, which enlarge molecular structure and improve the performance of charge neutrality, trussabsorption and sedimentation. It is an idea chemical reagent for the treatment seriously polluted raw water, low temperature and high turbidity water, and low temperature and low turbidity water. Features: 1. Combining the coagulatory advanges of Aluminium salt and Iron salt, and being able to form flocculation rapidly with more imporosity and rapid sedimentation; 2. Suited to raw water at various temperatures and having superious solubility; 3. Less dosage than other Aluminium salt water treatment chemicals and having lower cost.

Usage: 1. Solid PAC should be added after dissoved in water, and the dilution ratio is generally 2-20% (weight percent). 2. The dosage is generally 1-15 g solid PAC per MT raw water, and can be decided according to actual experiment according to different water quality and turbidness. 3、This product mustn't be stored with other chemical reagents. 4、solid products should be stored in a ventilated and dry place with the storage period of two years, and the availability won't be changed after the product is affected by damp.
