With the continuous development of society, people's life is getting better and better, but many people are not satisfied with working and start their own businesses. The continuous growth of old enterprises and the continuous rise of new enterprises will naturally produce more industrial sewage and agricultural sewage. If not treated properly, it will seriously damage the natural environment, while polyaluminium chloride does not contain chlorine Harmful substances such as aluminum and heavy metal ions can well deal with these sewage which makes the society headache.

In particular, industrial wastewater is rich in a variety of impurities, which will accelerate the formation. For example, if algae in the water grow crazy and are discharged directly into the river, it will cause serious pollution to the river, thus affecting the normal environment. Our domestic sewage is rich in a variety of substances harmful to human body. Imagine that the river around us was clear and clean many years ago, The people around us depend on the river to feed them. One side of the water and soil feeds one side of the people. How many people have been fed to eat, drink water, wash clothes and irrigate crops. How many people are happy in the river and how many people have memories of their childhood. But now people discharge sewage indiscriminately in order to pursue a better life. In order to curb this situation, they pay more attention to sewage discharge, Polyaluminium chloride can remove phosphorus, heavy metal ions and harmful substances. Whether it is industrial sewage, river water and lake water, polyaluminium chloride has a significant effect.

It can be said that polyaluminium chloride is suitable for all kinds of industrial wastewater and urban and village sewage. Polyaluminium chloride mainly settles rapidly through adsorption, bridging, making colloidal particles and suspended solids in water form fine mucus, and ending electric neutralization. It has the characteristics of fast hydrolysis speed, large specific gravity of floc, wide pH value scale, etc Heavy metal ions can be removed well, and polyaluminium chloride has the effects of, decolorization and sludge dewatering.
