MANAGEMENT of PHOSPHORUS REMOVAL in MUNICIPAL WASTEWATER TREATMENT PLANTS
As a result of uncontrolled discharge of wastewaters containing high levels of phosphorus to the receiving bodies could create adverse effects on water quality. Therefore phosphorus should be eliminated prior to discharging into aquatic environment together with carbon and nitrogen to reduce eutrophication risk. Control of effluent phosphorus level by enhanced biological methods became a standa...
متن کاملIn Enhanced Biological Phosphorus Removal ( Ebpr ) Processes
Phosphorus is an essential element for every living organism, but when it exceeds certain limit in water bodies, it will cause serious environmental issues, such as eutrophication. P accumulation in water bodies can be caused by non-point sources, such as agriculture land runoff, as well as from point sources such as wastewater effluent discharges. In order to avoid eutrophication of water bodi...
متن کاملA comparative environmental life-cycle analysis for removing phosphorus from wastewater: biological versus physical/ chemical processes.
Phosphorus can be removed from wastewater biologically, chemically, or through a combination of the two. In this study, we applied environmental life-cycle assessment to develop a metric with which decision-makers can compare processes. Two phosphorus-removal scenarios were contrasted-one based on a desktop-level design and one based on full-scale operational data. To achieve 0.5 mg/L effluent ...
متن کاملNutrient uptake rate and removal efficiency of Vetiveria zizanioides in contaminated waters
This research compares the performance of floating systems planted with Vetiveria zizanioides as a hydroponic approach for removing nutrients from two contaminated waters. For this purpose, two pilots with overall net volume of 60 litres were constructed and inoculated by secondary treated domestic wastewater (STDW) and irrigation water obtained from Minab reservoir (IWMR) in batch mode. Regard...
