Made in clay wastewater

From the main component is clay, master Le Ngoc Ninh, working at Phuc Yen Industrial College, Vinh Phuc, has developed a material to treat odor, color and reduce water pollution called Kabenlis. .

Kabenlis is a mixture made of kaolin clay with lis catalyst - a mixture of seawater or salt with CaO substance prepared in a certain proportion.

Kabenlis contains many SiO ₂ , Al ₂ O ₃ , MgO - are the basic components to create the main glue core, help absorb metal ions and suspended compounds insoluble in water. This compound is benign, does not affect aquatic plants and animals. Contaminated water processed through Kabenlis will become clear, odorless, and keep normal life for the animals

The process of treating polluted water with this substance is very simple, just dissolve it in water. Kabenlis prices are very cheap, 1kg Kabenlis products cost from 500 to 1,000 VND.

The testing of Kabenlis in laboratories shows that this method has the disadvantage of producing more mud than some other compounds, but it is easy to fix it and in fact, the disadvantage does not cause any significant harm to environment.

Until now, scientists have invented many polluted water treatment substances but are expensive or difficult to apply on a large scale. Research of master Le Ngoc Ninh contributes to overcome the above situation.
