Wastewater treatment handbook

8 ACTIVATED SLUDGE PLANT, SUPER, entirely made of polyethylene, in one piece, seamless, composed of the following phases: SEWAGE INLET through a polypropylene or PVC 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 diffusers, delivering fine bub- bles. 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. 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’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 Activated sludge plant SUPER 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 diffuser have to be periodically checked. A bacterial tablet may be dosed in the oxidation volume in order to accelerate plant start up. Make sure proceed with dampened sand filling of the gaps around it. Finish with a 5 cm thick light concrete casting (or with reinforced concrete in case of car passage on top of the plant ).Make sure that covers are always inspectionable.In case a venting column has not been created, install a siphon before the plant.Connect the system to 220 Volts power line. 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 kit carrabile cm 10 sand earth light concrete walk-on cover cm 10 WALK-ON SOLUTION INSTALLER ENGINEER (SPECIFICATIONS) USER DRIVE-ON SOLUTION 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 sand earth www.baygar.com
