Filtration assembly e.g. for waste water, wine or pig-rearing slurry comprises series of linked modules with bases and filter medium that traps odours

摘要

The filtration assembly (20) consists of a series of modules (2), each having a base (4), a filter medium (6) fixed to the base, and a connecting system (18) that links adjacent modules. The filter medium is designed to trap odours and can be made from activated carbon with a layer of a photocatalytic agent such as titanium dioxide to regenerate the activated carbon. The assembly also has a reinforcing element such as a glass or metal grille between the base end filter medium.
