Upgrading of waste stabilization ponds using a low-cost small-scale fine bubble diffused aeration system

Waste Stabilization Ponds (WSPs) are known for the economical treatment of wastewater, especially if low-cost land is available. In this research to overcome some common operational problems such as undesirable color changes in ponds, severe odor problems, and most importantly, deviations from the e...
