Comparaison théorique de dispositifs d'ANC : les filières par " cultures libres" autorisées au 1 août 2014

Abstract : The order liying down the technical requirements relating to the onsite treatment system receiving a daily organic load lower or equal to 1,2 kg of DBO5 lead to the development of new technical devices. This report is designed to summarize the regulation elements available on interdepartmental website about on site treatment. This report deals only with one type of devices: the free growth system (activated sludge and Sequencing Batch Reactor). This synthesis report includes 97 technical approvals and their related available user manuals; it concerns 25 manufacturers. Each description contains the different treatment steps, the sizes and the volumes of each tank which composes each system. Moreover in this report, you will find different graphics which compare the different manufacturers between themselves. To compare them, we use special wastewater treatment characteristics like mass load, volume load, hydraulic retention time, clarifier area and sludge storage volume. So we can see many design differences between manufacturers and sometimes for the same manufacturer when it sells different product sizes, it doesn’t respect homothetic or proportional rules.
