Silica decolorizing sand is an adsorbent used to adsorb impurities and colors from recycled oil through a decolorization filtration process.

The oil becomes clear, bright, and free of sulfur compounds after being filtered through decolorizing sand, enhancing the quality of the oil. It is a widely used decolorizing adsorption product on the market.

Silica decolorizing sand offers advantages such as low loss, low cost, and wide applicability. It solves the难题 of waste disposal, as the waste residue washed with decolorizing sand does not stick together, clump, or solidify, making it reusable.
