Abstract
A constructed wetland system pilot project was constructed in 2022 in one of the houses in Al-Diwaniyah Governorate, Iraq. This system is a constructed wetland system (CWS). This system was planted with Typha domingensis. The present research deals with blackwater collected from a single house in Iraq’s Al-Diwaniyah Governorate. This house consists of three apartments. Water from these flats is drained into separate water manholes (BW and GW). Black water (BW) collected is the subject of the current study, where the black water was discharged from the manhole to the constructed wetland station in the house. This study is to investigate various treatment processes for treating blackwater for reuse. Blackwater treatment was examined first in batch tests to define optimal operating conditions, which include the settling time. The experimental method involves evaluation of the treated effluent to reach the allowable limits of water reuse according to Iraqi quality standards to reuse the water for irrigation (IQS 2012) and Egypt’s reclaimed water reuse standards (Egypt Decree 2013). The efficiency of a sedimentation operation was examined from to determine the optimum time. Further treatment by Constructed wetland was examined. Final overall removal rates for TSS, BOD5, COD, TP, and TN were 97.16%, 91%, 81%, 63%, and 69.2%, respectively. The present study that Constructed wetland could successfully efficient to removing the contamination by saving space, energy and labor less.
