Decolorizing Sand

Decolorizing sand, is also called oil decolorized sand and can replace decolorizing clay to deal with different oil industry. It has good fluidity and function of deacidification, deodorization, decolorization and adsorption and filtration media. It is used in the final refining process in the diesel production process (used in the outflow of diesel). A certain proportion of black diesel oil is light yellow transparent after being adsorbed and purified by filter sand (decolorized sand).

The working principle of decolorizing sand is to utilize the porous structure to adsorb particles such as melanin to achieve a decolorizing and deodorizing effect. Decolorizing sand has the function of decolorization, but it does have the function of deodorization and its oil rate is low.  Because it has the function of selective adsorption.

Decolorizing Sand1. Decolorizing, refining and purifying industrial oil such as lubricationg oil, diesel oil, paraffin
wax, gasoline, grease, kerosene, white oil etc.
2. Recycling and regenerating industrial waste oil, such as machine oil, lubricating oil, used
