Polyaluminium chloride PAC powder for water treatment
Spray dried Polyaluminium chloride PAC solid light yellow powder is a novel highly effcient inorganic polymer coagulant.PAC-2 is made of aluminium hydroxide,hydrochloric acid and calcium aluminate powder by advanced technology.The price of PAC-2is reasonable,
its water purification effect is higher than the trditional common inorganic coagulants such as aluminiumsulphate and ferric salt.The solid powder is spray dired light yellow.
polyaluminium chloride PAC spray dried first grade light yellow powder for drinking water treatment ,has following performance:1.low dosage needed,Flocs quickly and settle quickly,low aluminium residual.2.low decrease of water alkalinity and effluent PH value3.high solubility,low impurity content,Low causticity.4.efficient in wide PH range,can be used in the PH range of 5.0-9.05. Strong adaptability to turbidity,alkalinity and temperature.
Appliction areas:1.Drinking water treatment and pre treatment for pure water preparation2.treatment of reinjection water for oil wells.
Package
25 kg packed in plastic woven bag lined with PE bag
