Abstract
The aim of this research was to assess the treatment efficiencies for gully pot liquor of experimental vertical-
flow constructed wetland filters containing Phragmites australis (Cav.) Trin. ex Steud. (common reed)
and filter media of different adsorption capacities. Six out of 12 filters received inflow water spiked with
metals. For 2 years, hydrated nickel and copper nitrate were added to sieved gully pot liquor to simulate
contaminated primary treated storm runoff. The findings were analyzed and discussed in a previous paper
(Part A). Case-based reasoning (CBR) methods were applied to predict 5 days at 20°C N-Allylthiourea biochemical
oxygen demand (BOD) and suspended solids (SS), and to demonstrate an alternative method of
analyzing water quality performance indicators. The CBR method was successful in predicting if outflow
concentrations were either above or below the thresholds set for water-quality variables. Relatively small
case bases of approximately 60 entries are sufficient to yield relatively high predictions of compliance of
at least 90% for BOD. Biochemical oxygen demand and SS are expensive to estimate, and can be cost-effectively
controlled by applying CBR with the input variables turbidity and conductivity.
