Features and performance:
- Solid products appear in flakes or blocks in white, light green or light yellow. Aqueous product is colourless and transparent, light green or light yellow.
- Aluminium sulfate is a compound polymer with a large molecular structure, strong adhesion, well-adaptability to all kinds of raw water, little influence on water (4- 11), good water purification effect and poor corrosivity to equipment and pipelines. Product quality standard conforms to HG2227-2004 standard.
Application range:
Mainly used in the flocculation and sedimentation treatment of drinking water, industrial water and municipal sewage. The aluminium hydroxide will be produced when aluminium sulfate is added into the water, which is colloidal,bacteria-absorbed and precipitated, as well as other colloids and suspended substances. This is favourable for controlling the water shade and taste.
