Performance Studies of Oxidation Ponds

Abstract

Performance Studies of Oxidation Ponds research is concerned with study and checks the suitability of waste oxidation ponds (WOP) for treating wastewater in Al-Dewaniyah province by taking a sample of community of 10000 populations. Experimental work had three cases depending on many considerations such as economical and specification of final effluent. A model of two ponds (facultative and aerobic) in series was used as first case of experimental work.

Then third pond with aeration process to aerobic pond were added to the series as second case to improve the effluent. At last, sand filter was used to polish the final effluent from aerobic pond. The three ponds had the same surface area (5.75m*2m) but with different depths, where it was 2m for anaerobic pond, 1.5m for facultative pond and 0.75m for aerobic pond.

Conclusion

According to the results from the experimental work on the model of ponds which contained anaerobic, facultative, and aerobic process, the following conclusions may be listed below:-Raising of TSS, BOD, COD and most of the other characteristics of influent raw wastewater to waste oxidation pond because of the break down most of the mechanical parts (including bar screen and grit chamber) of AlDewaniyah WWTP which started working in 1983 that affects the characteristics of influent raw wastewater of the experimental model.
