Polyaluminium
chloride
Main characteristics:Compared with other coagulants, this product has the following
strong points: 1, Wide range of application.
2,
Good settling behavior. 3, Wide range of suitable PH value(5-9). 4. Stable settling
behavior can be kept when the water temperature is low. 5, Degree of alkalisation
is higher than other aluminium salt,iron salt,small corrosion to equipment.
Technical index and use: According to the improvement of people's requirement
on water quality, our company has developed polyaluminum oxide series products:polyaluminium
chloride,aluminium chlorhydroxide,ferric chloride,aluminium sulphate,compound
iron etc..
