1. Removal of suspended matter and colour: PAC can well remove suspended matter and colour in water, including particulate matter such as mud and sand and pigmented matter such as organic dyes.

2. purify water quality: PAC can purify water quality, including removing pollutants such as heavy metals, organic matter, odour, smell and bacteria in the water, so as to improve the transparency and cleanliness of water.

3. Adjustment of water quality: PAC can be adjusted according to different water quality conditions, so that it meets the required water quality standards. For example, in areas with high water hardness, PAC can improve the quality of water and prevent the formation of scale.

4. Improve the efficiency of water treatment: the use of PAC can improve the efficiency of water treatment, reduce the cost of water treatment, to avoid the use of traditional iron salts, aluminium salts and other water treatment chemicals brought about by water pollution and waste disposal problems.

5. Environmentally friendly: Compared with traditional water treatment chemicals, PAC has less impact on the environment and does not contain acidic substances such as chlorine and ammonia, thus reducing the pollution and harm to the environment.
