ABSTRACT: In recent years, an increase in interest in hybrid constructed wetland systems (HCWs) has been observed. 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 Pomerania Region of Northern Poland, the effective removal of organic matter (from 74.9 to 95.5% COD) in the loading range 1.5-17.0 g CODźm-2źd -1 was confirmed. Efficiency of total nitrogen (TN) removal varied from 23.4 to 79.2%. The most effective removal of TN (2.0 g.m -2.d-1) occurred in the system with vertical flow compartments with intermittent loadings.
