  • Biological filtration system with socks of absorbent material
    Patent number: 8673140
    Abstract: In an apparatus for treating wastewater, e.g sewage water, the water passes through absorbent material. The material comprises e.g inexpensive scraps or off-cuts of plastic foam. The pieces of material are contained by being stuffed into lengths of plastic mesh tubing, which are then formed into closed-ended socks. The socks are stacked in layers, and the water to be treated is trickled down through the layers. The socks can also advantageously be used for anaerobic and submerged treatment of wastewater.
