Performance evaluation of wastewater stabilization ponds in Yazd-Iran
Background: Yazd waste stabilization pond facilities consist of three stabilization pond systems, module 1, module 2 and module 3 that AWSP module 1 has started its operation. The existing facilities have had several problems in their operation. The objectives of this research were to evaluate the performance of stabilization ponds in wastewater treatment of the city of Yazd, due to several pro...
متن کاملThe Fate of Heavy Metals in Wastewater Stabilization Ponds
-The distribution of toxic heavy metals was studied throughout the process of treatment of domestic wastewater by stabilization ponds. The concentrations and distribution of free and bound zinc, cadmium, lead and copper through the various stages of a treatment plant were analyzed by Anodic Stripping Voltammetry (ASV). Only a slight decrease in the total metals concentration was observed during...
متن کاملBacterial Proliferation Reduces Sulphur Toxicity in Stabilization Ponds: Safer Water Resources by Photosynthesis
Background: Studies suggest that sulfur may react with plants or monocellular organisms, such as fungi, to produce toxic agents. It has been theorized that sulfur enters cells and affects their respiration. This study reports on a phototroph development that leads to the diminution and/or production of sulfur and release of hydrogen sulfide from public ponds. Methods: This study was conducted ...
متن کاملMacrophyte waste stabilization ponds: An option for municipal wastewater treatment
The objective of this research is to evaluate the performance of macrophyte waste stabilization pond system for municipal wastewater collected from Taxila (Pakistan). A model of macrophyte waste stabilization pond system was operated for six trials with each trials comprising different detention times that is 3, 5, 7 and 10 days, respectively. For the treatment, locally available macrophyte (wa...
