Evaluation Comparison of Sub-Surface Flow Constructed Wetland and Integrated stabilization pond in Removal of Most Important Parasitic Contamination from Municipal Wastewater
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2015, Vol 9, Issue 10
Abstract
Sub-surface flow constructed wetland and integrated stabilization pond are most important of domestic wastewater natural systems. The aims were also to measure the efficiency of the wastewater treatment plant of Ghasr-e-Shirin (wetland), Islam Abad e-Gharb and Sarpol-e-Zahab (stabilization pond) in the removal of helminthes ova and protozoa cysts.Raw and treated wastewater samples were taken at the inlet and outlet of each treatment plant, weekly within the period of six months. Totally, 144 samples were tested by microscopy (McMaster counting slide) using the modified Bailenger Method (MBM).Results showed that the average removal efficiency of helminth eggs and protozoa cysts in artificial wetland process was 99.7 ± 0.23 % and 100%. While no helminth eggs and protozoa cysts were observed in effluent of both stabilization ponds systems therefore the efficient removal of both parameters in these systems were 100% estimated. In all three treatment plants, effluent the maximum number of helminth egg was related to Ascaris lumbricoides. According to the results, performance of three treatment plants was favourable in term of helminth eggs and protozoa cysts removal and there were no significant differences between them (Pvalue> 0.05).
