The objectives of the study were: (i) to examine the efficiency of nutrient removal during the treatment of dairy farm effluent in a two-pond system, and (ii) to produce an inexpensive but effective nutrient trap which could be recycled as a nutrient source or soil mulch. The concentration of chemical oxygen demand (COD), biological oxygen demand (BOD), nitrogen (N), phosphorus (P) and potassium (K)...
The Columbia Wastewater Treatment Wetland (“Columbia Wetland”) is a constructed cattail wetland in the Missouri River floodplain outside Columbia, Missouri, USA. the wetland receives mixed primary and secondary effluent (≈60,000 m3 d−1, BOD5≈30 mg L−1, TSS≈13 mg L−1, NH4−N≈8 mg L−1) from a conventional treatment plant. During its first 6 years of operation (October 1994 through November 2000), the...
