Application of Kaolin in Water Treatment

Kaolin is a mineral that exists in nature. Our country is very rich in kaolin resources. Kaolin has strong adsorption properties. At the same time, kaolin contains a variety of metal elements and is used to prepare water treatment reagents. This paper discusses the use of kaolin in water treatment. The application in is summarized, hoping to be helpful to others.

Preparation Of Adsorbent

In water treatment, adsorption is a relatively effective treatment method, but due to the high cost of adsorbents, it is difficult to promote. As a mineral, kaolin is rich in resources in our country, and because of its strong adsorption performance, it has been widely used in water treatment.

Preparation of Catalyst Support

Kaolin has strong adsorption performance, which is related to its porous structure, which can also be used as a carrier of photocatalyst to improve the catalytic performance of photocatalyst.

Synthetic Flocculant

Kaolin contains a variety of metal elements, especially iron and aluminum. Using appropriate methods, iron and aluminum can be used to prepare excellent flocculants for water treatment.

Synthetic Film

Membrane filtration has always been a focus of attention in the water treatment industry. The bottleneck lies in the high cost of membranes and the difficulty of membrane pollution control. The use of kaolin to prepare membranes or as composite materials has achieved good results in the treatment of sewage and wastewater.

Summarize

my country's water treatment is currently facing great challenges, and it is imminent to screen water treatment agents with low treatment costs and good treatment effects. As a mineral, kaolin is rich in resources in our country and has a variety of processing functions, and its application prospects are broad.
