EVALUATION DE LA MEILLEURE TECHNOLOGIE DISPONIBLE DANS LE DOMAINE DU TRAITEMENT DES EAUX USEES
Journal Title: Larhyss Journal - Year 2016, Vol 27, Issue 27
Abstract
Our main objective in this experimental study is to compare which one of the three technologies including Activated sludge process, sequential batch reactor technology and Bio membranes process has the main benefits with fewer disadvantages, that is what we have demonstrated through physical and chemical analyses of the above mentioned processes. The assessment applies BAT guidelines based on the characteristics of the technology itself and of urban areas. These characteristics narrowed the choices for a fitted treatment and reuse technology to be used in a specific country context. The assessment came to the conclusion, that there is one technology that fits all existing conditions which is SBR technology with removal efficiency by 95.6% of TSS, 98% of BOD5, 93.5% of COD and 75% of NH-3. As a general recommendation, it is advisable to choose the cheapest technology in terms of capital, operation and maintenance cost. In addition to lowest cost, the technology that requires the least skills in management should be selected and allowing to be reused accordingly to international Wastewater Reuse Standards.
