FILLING ELEMENTS sand cm 10 earth inspection covers venting pipe inspection covers 22 Polyethylene PACKAGE trickling filter based treatment plant is composed of: GREASE TRAP, made of PE. It is meant to be put on the grey water line. TWO BIOLOGICAL IMHOFF TANKS, made of PE. TRICKLING FILTER, made of PE.Equipped with a venting pipe which allows air in the filter thus speeding up bacterial growth. Biological Imhoff tank is in front of the trickling filter and decreases organic load entering the filter itself. Polypropylene filling elements are support for the bacterial film that is in charge of transforming pollutants in settable sludge. This sludge is removed in the following biological Imhoff tank. INSPECTION CHAMBER, made of PVC. It is installed in order to allow water sampling. Dig a hole of appropriate dimensions and line a 10 cm thick sand layer at the bottom, g ra i n s i ze 0 - 5 m m , dampen the sand and level it. Connect the black water pipe to the biological Imhoff tank. Connect the grey water pipe to the grease trap. Fill the tanks with clean water to start the process.Proceed with dampened sand filling of the gaps around it. Finish with a 5 cm thick light concrete casting and a 40 cm thick earth layer on top (or with reinforced concrete in case of car pas- sage on top of the plant ).Make sure that covers are always inspectionable. Verify that installation has been correctly carried out. Periodically remove excess sludge from biological Imhoff tank. Periodically control that the filling material level in trickling filter remains the same. Micro-organisms take more than 40 OPERATIONAL CHARACTERISTICS The grease trap is meant to remove oils and grea- ses from the water flow and enable a better perfor- mance for the trickling filter.The biological Imhoff tank, instead, separates suspended solids from the water flow and "digest" them. The trickling filter transforms pollutants into settable sludge. It is designed on the basis of net volume: Vn= organic load/volumetric load days to reach their standard performance level. If water flux is interrupted, micro-organisms activity is stopped.It will take another 40 days to re- start the process.It is advisable to clean the trick- ling filter once a year.
