泡沫滤珠滤料是一种新型过滤材料能把水质中的混凝、澄清、过滤三道工序在一容器内完成。泡沫滤珠滤料还可可直接供应水塔，适用于中小型水处理设备，也可用于船舶水处理系统。可发性聚苯乙烯泡沫滤珠（EPS发泡塑料滤珠），系在悬浮聚苯乙烯树脂中加入石油液化气而发泡制成的珠状颗粒白色小球，属轻质滤料，堆密度80-100kg/cm3,孔隙率50%左右。
泡沫滤珠其本身具有重量轻、比表面积大、吸附能力强、不破碎、孔隙率高、滤速快、脱污能力强、滤料均匀、使用寿命长等优点。
Bubble bead filter material is a new type of filtration material can change the coagulation in water quality, clarification, filtration three procedure done in a container. Bubble bead filter material is cocoa directly supply water tower, suitable for small and medium-sized water treatment equipment, can also be used for water treatment system of the ship. Polystyrene foam filter bead (EPS foamed plastic bead), is in the suspension of polystyrene resin joined the liquefied petroleum gas and foam beads, bead particles made of white light filter material, the bulk density of 80-100 kg/cm3, porosity is about 50%.
Foam filter bead itself has light weight, large specific surface area, strong adsorption ability, not broken, high porosity, quick speed, escapes the dirt ability, filter material evenly, long service life, etc.
