目前在废气生物滤床/池处理过程中使用的过滤材料有无机填料和有机填料两类。无机填料多以加气混凝土、多孔陶粒、熔岩颗粒或矿渣等无机材料为主，有机填料有松树皮、木片、植物根须、枝杈、锯末、泥炭等及其混合物。在发达国家,树皮做为生物滤料在废气出理过程中已经广泛使用，我国在化工、制药、电镀、喷漆、印刷等行业的有害污染气体处理以及废水处理厂、堆肥厂、垃圾填埋厂产生恶臭处理等方面已经广泛使用。格瑞斯树皮是以松树皮为主要原料，经过人工剁块、分级筛选、包装等工序加工而成的环保有机滤料。
一、产品主要特点
1、具有较大的比表面积，污染物与微生物的接触面积大，有利于微生物接触挂膜和生长，保持较多的微生物量；有利于微生物代谢过程中所需氧化和营养物质以及代谢产生的废物的传质过程。
2、表面粗糙，有利于微生物的附着、生长；总空隙率高达70%，其容纳微生物生活空间及吸附污染物空间大，可有效的将有毒气体截留下来，并吸附在树皮上。
3、具有坚韧的纤维结构，与其它树皮相比，松树皮不易腐烂，使用寿命长，可使用3-5年。
4、松树皮的本身养分含量高，为微生物提供优良的生长环境。
5、来源于大自然，可再生有机物，对环境无二次污染。
