In this research, the quality of wastewater discharged into environment has been investigated. The effluent from solar desalination pond contains large amounts TDS (3.68 grams per liter) and TH (6.50 liter). Since use filter is not economical in case, three types commercial coagulants such as aluminum sulfate, ferric chloride sulfide have used study. main parameters effectiveness inorganic coag...
Rock filters are an established technology for polishing waste stabilization pond effluents. However, they rapidly become anoxic and consequently do not remove ammonium-nitrogen. Horizontal-flow aerated rock filters (HFARF), developed to permit nitrification and hence ammonium-N removal, were compared with a novel vertical-flow aerated rock filter (VFARF). There were no differences in the remov...
Introduction: Wastewater contains a large number of pathogenic and non-pathogenic microorganisms that can become bioaerosols during the treatment processes in different units of the treatment plant, and pose a risk to workers and nearby residents. In this study, the release of bioaerosols from a wastewater treatment plant of Morche Khort Industrial Town was investigated. Materials and Methods:...
In Taiwan, constructed wetlands have received tremendous interests for water quality enhancement due to insufficient sewage treatment and groundwater deterioration. The main objectives of this study were to investigate pollutants removal mechanisms and efficiency within the field-scale natural purification hybrid systems. The systems included an oxidation pond, two serial surface flow wetlands ...
