EFFICIENCY OF ENTEROCOCAL AND THERMOTOLERANT COLIFORMING BACTERIA REMOVAL IN CONSTRUCTED WETLAND USED FOR WASTEWATER TREATMENT
FIŠEROVÁ, Alena
Constructed wetlands (CWs) have their origin in natural wetlands and they are used for a wastewater treatment as an alternative of the classical technology. In the Czech Republic are used only CW with subsurface horizontal flow with emergent macrophytes for the wastewater treatment. The efficiency of the enterococal and thermotolerant coliforming bacteria removal was followed in the CW in Slavošovice. In the regular intervals (2-6 weeks) from May 2006 to March 2007, wastewater was sampled at the inflow, after the mechanical pretreatment and at the outflow. The number of the enterococal and thermotolerant coliforming bacteria was calculated in the samples and the efficiency of the bacterial removal was evaluated during winter and summer seasons.
