Use and specifications
1. DISTRIBUTION PIPE: perforated pipe for even distribution of the effluent onto the surface of the filter.
2. FILTER MEDIA: plastic bulk fill material with a large surface area that acts as a support on which the anaerobic bacteria responsible for treating the effluent can develop.
3. COLLECTION PIPE: pipe to draw off the treated effluent from the bottom and send it to the outlet.
TECHNICAL CHARACTERISTICS
A trickle filter is a biological reactor, inside which the micro-organisms that purify the effluent develop on the surface of special bulk fill material (filter media). The uniform distribution of the effluent through the filter guarantees maximum contact between the organic material to purify and the biological film covering the spheres making up the fill material. More specifically, the bacteria that grow and develop inside the anaerobic trickle filter consume the organic load in the effluent in the absence of dissolved oxygen.
USE: secondary treatment of domestic sewage.
REFERENCE REGULATIONS: Inter-Ministerial Committee for the Protection of Waters Resolution No.48/77, Legislative Decree No.152/06, Emilia Romagna Regional Resolution 1053/2003, Umbria Regional Resolution 1171/2007. The Emilia Romagna and Umbria Regional Resolutions require application of the relationship S=N/h2 connecting the filter surface (S), the population equivalent number (N) and the filter height (h). The latter value must be between 0.9 and 1.5 m.
