Magnesium Hydroxide

Hebei Messi Biology Co., Ltd. stated that in the process of extracting slurry magnesium hydroxide from concentrated seawater, the presence of calcium is an important factor affecting the purity and quality of the product. This paper first studied the pretreatment process of extracting magnesium from concentrated seawater, and investigated the reaction conditions of calcium removal

Hebei Messi Biology Co., Ltd. stated that high-concentration and high-stability magnesium hydroxide slurry can be obtained by adding anionic polyelectrolytes to magnesium hydroxide emulsion. When the polyelectrolyte concentration is 25% and the amount added is 0.5%-1.5% of the total amount of magnesium hydroxide (on a dry basis), the obtained slurry contains 51%-62% solids, 38%-49% water,

Hebei Messi Biology Co., Ltd. stated that when the fluid powdered magnesium oxide is mixed or dry-ground in the presence of a small amount of water, a highly efficient hydration reaction will occur to generate powdered magnesium hydroxide; when the product is aged in the presence of water, the hydration efficiency is greatly improved, and

Hebei Messi Biology Co., Ltd. stated that after simple purification of brine, lime as a precipitant is added to produce magnesium hydroxide precipitation. The slurry produced by the reaction must be concentrated by precipitation and filtration to wash away excess chloride to make slurry with various solid contents. When preparing the slurry, the stability of

Application of slurry magnesium hydroxide in water treatment Slurry magnesium hydroxide has the following advantages when used for water purification: high activity, good removal effect on suspended solids, COD, BOD oil, odor, heavy metal ions, phosphates, sulfates, acids, dyes, phenols, and silicates in wastewater, with a removal rate of 75%-99%, especially suitable for papermaking wastewater,
