Silica decolorizing sand is an adsorbent used to remove impurities and color from reclaimed oil through decolorization filtration.

The oil is clarified and brightened after being filtered through a decolorizing sand filter, removing sulfur compounds from the oil, thereby enhancing the quality of the oil. It is currently one of the more commonly used decolorizing adsorption products on the market.

Silica decolorizing sand offers the advantages of low loss, low cost, and wide applicability. It solves the difficult problem of waste disposal, as the waste residue washed with decolorizing sand does not agglomerate, clump, or solidify, making it reusable and addressing the environmental protection challenge.
