Abstract

Un medio de filtración compuesto en polvo incluye partículas compuestas que incluyen al menos una partícula de diatomita y al menos una partícula de perlita expandida sinterizadas juntas. El medio de filtración compuesto en polvo puede incluir de aproximadamente 7% en peso a aproximadamente 90% en peso de diatomita, de aproximadamente 93% en peso a aproximadamente 10% en peso de perlita expandida. Menos de aproximadamente 1% de sílice cristalina total puede estar presente en el medio. El medio puede tener una permeabilidad de al menos 0.25 darcy. La diatomita y la perlita expandida pueden sinterizarse o calcinarse con o sin un agente fundente.
