Abstract: | Analysis of economic data pertinent to the existing municipal wastewater treatment plants (MWTP) in Greece is presented. Thisinformation is important when budgeting for future plants. Thedata include land usage and the costs for construction, operationand maintenance of the form y = ax b, where a and b are calculated coefficients. Equations for cost and landuse were produced for specific systems. Personnel and energy aspects are analysed as they are major contributors to operationalcost. A life cycle analysis (LCA) of plants is undertaken. The results of such an analysis should suggest the most preferabletechnology under given circumstances. Thus, under high energy costs and low level of automation and operation, at low F/M ratios, conventional activated sludge systems are relatively notcost effective. In addition, for cost of land less than US$30 per m2, waste stabilisation ponds are cost effective subjected to minor earthworks. |
