​Magnesium hydroxide, white amorphous powder.

One of the main influencing factors of eutrophication in rivers and lakes is ammonia nitrogen pollution. At present, the annual output of synthetic urea and ammonia in China is more than 40 million tons. The production of various types of ammonia nitrogen products allows enterprises to discharge large amounts of ammonia nitrogen wastewater. At the same time, the natural world will produce ammonia-nitrogen wastewater in the process of waste fermentation, and the total amount will exceed 100 million tons per year, which will have a greater impact on the natural environment.

Ultrafine natural magnesium hydroxide refers to an ultrafine magnesium hydroxide prepared by calcination and hydration using natural magnesium carbonate minerals (mainly magnesite).
