“…The average removal efficiency for COD, BOD5, and TSS for the first six runs were 80, 78, and 90%, respectively. The results of COD removal reveals compatibility with Alejandro's et al findings [9], especially for the unplanted HSF model. Various studies showed a BOD5 removal in the range of 67 -83%, which is close to the related outcomes of this work [10,11].…”

“…The organic loading rate (OLR) was 3.3 g(COD).m -2 .d -1 (±1.9) as an average for the six runs, whereas it was 21.1 g(COD) m -2 d -1 for the seventh run. The OLRs for the six runs were lower than 12 g(COD) m -2 d -1 which is recommended by USEPA (2000) for HSF constructed wetlands [9]. This interprets the acceptable removal of COD, BOD5, TSS, and turbidity contaminant parameters as illustrated in Figure 2.…”

Ramadi is one of the Iraqi cities which doesn't have a WWTP. The generated domestic wastewaters are treated by the individual septic tanks. Hence, most domestic wastewater is percolating into the subsurface water and groundwater causing their pollution. The tragedian water shortage scenarios predicted by other studies have motivated the looking for new water resources. The reuse of treated wastewater is one of these alternatives. Therefore, this study tries to investigate the feasibility of using such a cheap and easy controlled technique as a horizontal subsurface flow (HSF) for treating wastewater. A lab-scale reactor has been built up from acrylic, one half of its height was filled with soil that has been collected from a selected region. The reactor was charged with wastewater using batch feeding (30 L each run) and the study lasted for 3 months with an average of one run weekly including the acclimatization period. Results revealed the fairly contaminants’ removal, where the average removal efficiency of COD, BOD5, and TSS were 76%, 73%, and 90%, respectively. In conclusion, the HSF is a reasonable, low cost, less complicated treatment technology that could be adopted as an alternative water resource for irrigation of the green belt.
