Depuración de augas residuais (manual en inglés)

6 I N S T A L L A T I O N I N S T R U C T I O N S a n n e x 1 ACTIVATED SLUDGE PLANT, SUPER PLUS, entirely made of polyethylene, in one piece, seamless, composed of the following phases: SEWAGE INLET through a polypropylene pipe section. OXIDATION of the incoming sewage. An air-blower is positioned in a special compartment inside the plant and it feeds air to the waste water. It works continuously and it is absolutely silent. Air allows aerobic micro- organisms to perform organic material removal. AIR DIFFUSION by means of epdm uncloggable membrane diffusers, delivering fine bubbles. SETTLING of solids carried by the flow from the oxidation. This phase is performed in a partition of the plant volume, where stillness and appropriate retention time are granted. SLUDGE DIGESTION at the bottom of the oxidation tank where settled solids are stored. DISINFECTION of the oxidised and clarified flow.A chlorine tablet continuously relea- ses active reactant to the outlet flowing on top of it. Dig a hole of appropriate dimensions and line a 10 cm thick sand layer at the bottom, grain size 0-5mm, dampen the sand and level it. Lay the plant down.Connect SUPER PLUS ’s outlet pipe to an inspection chamber by means of a Ø............. pipe. Connect the general discharge pipes to the SUPER’s inlet pipe by means of a polypropylene or PVC pipe having Ø.............. Fill the tank with clean water and proceed with dampened sand filling Activated sludge plant SUPER PLUS treats waste water from civil dwellings. It is installed between the sewage pipe coming from the house and final discharge. It performs sewage depuration and allows to discharge it in superficial water body. Following installation, air blower and diffu- ser have to be periodically checked. A bacterial tablet may be dosed in the oxidation volume in order to accelerate plant start up. Make sure of the gaps around it. Finish with a 5 cm thick light concrete casting (or with a 25 cm thick reinforced concrete in case of car passage on top of the plant). Always cristall a siphon in front of the plant,in order to avoid odour to go back inside the house. In case there is no venting coloumn, it is necessary to connect a PVC ø 2”pipe to the ausiliary venting connection foreseen on the plant.This pipe has to go as for up as the house roof. there is no sludge stagnation in the settling tank or anaerobic processes may occur. Insert the chlorine tablet in its proper position (it needs to be replaced every 3 months).Excess sludge must be removed from the plant every 6 months, con- tacting specialised companies. Make sure a ven- ting column exists. If it does not, place a siphon before the plant or create a venting column. reinforced concrete drive-on cover cm 10 walk-on cover cm 10 INSTALLER ENGINEER (SPECIFICATIONS) USER To obtain further information please read the installation use and maintenance booklet attached to the plant.
