Energy efficiency of small waste water treatment plants in the Baltic Sea region – a comparative case study

Abstract

Presented study will compare energy efficiency indexes [1] for three exemplary waste water treatment plants (WWTP) in the Baltic Sea region. Exemplary WWTPs include Goleniów Water Treatment Plant (Location 1 - Poland), R?nne - Bornholm (Location 3 - Denmark) and H??r (Location 2 – Sweden, WWTP of Lyby and Ormanäs). Their geographical position is presented in Fig. 1. Time evolution of energy efficiency indexes and the influence of renewable energy sources on energy efficiency indexes will be analysed.
