1. Reasons for Choosing
Constructed Wetlands (CWs)
LOCAL CONDITION
CONCLUSION
(1) Treatment targets:
•Carbon removal (BOD,
COD, SS)
•Enhanced nutrient
removal (N, P)
•Hygiene?
•Carbon removal of CWs is
equivalent to convent. technologies.
•N removal – with a
properly designed CW – can be
brought to similar levels as with convent. technologies
nowadays.
•P removal in CWs decreases over time, yet an acceptable
mean elimination rate of 50% is considered
feasible.
•Soroca WWTP shall be
based upon 2-stage CWs. These systems feature superior pathogen
removal, as compared to convent. technologies.
Properly designed 2-stage CWs enable enhanced nutrient removal and even have better hygienic effluent quality than conventional technologies.
