Efficiency of pollutant removal by five multistage constructed wetlands in a temperate climate

Abstract

In recent years, an increase in interest in hybrid constructed wetland systems (HCWs) has beenobserved. These systems are composed of two or more filters with different modes of sewage flow.Based on over eight years of monitoring, carried out at five local HCWs located in the PomeraniaRegion of Northern Poland, the effective removal of organic matter (from 74.9 to 95.5% COD) in theloading range 1.5-17.0 g COD·m-2·d-1 was confirmed. Efficiency of total nitrogen (TN) removal variedfrom 23.4 to 79.2%. The most effective removal of TN (2.0 g·m-2·d-1) occurred in the systemwith vertical flow compartments with intermittent loadings
