HYDRAULIC BEHAVIOR IN THE DOWNFLOW HANGING SPONGE BIOREACTOR Karakteristik Hidraulik pada Bioreactor Downflow Hanging Sponge
Performance efficiency in a Downflow Hanging Sponge (DHS) bioreactor is associated with the amount of time that a wastewater remains in the bioreactor. The bioreactor is considered as a plug flow reactor and its hydraulic residence time (HRT) depends on the void volume of packing material and the flow rate. In this study, hydraulic behavior of DHS bioreactor was investigated by using tracer met...
متن کاملPersistent toxic chemicals: more than Stockholm persistent organic pollutants.
Schafer and Kegley bring up the important issue of excessive chemicals exposure of children. However, they do not consider in depth the "cumulative and simultaneous exposures faced by children, (.) moving beyond the chemical-by-chemical approach of the past", as quoted from the US Environmental Protection Agency national agenda to protect children from environmental health threats. Existing evi...
متن کاملan evaluation about the role of microorganisms isolated from the soil in the biological removal of toxic petroleum pollutants
polycyclic aromatic hydrocarbons (pahs) such as anthracene, naphthalene, and phenanthren are the most toxic and carcinogenic pollutants which cause severe damages on soil and water resources. in order to remove these materials, biological methods and using potential of local microorganisms of oil contaminated soils are preferred because of cheapness and availability. existing soil microorganism...
متن کاملBiological Removal of phosphate from Synthetic Wastewater Using Bacterial Consortium
The biological phosphorus removal is a microbial process widely used for removing phosphorus fromwastewater to avoid eutrophication of water bodies. The study was aimed to screen the efficient phosphatereducing isolates and used to remove phosphate from synthetic wastewater using batch scale process. Thethree most efficient phosphate reducers were isolated and screened from eu...
متن کاملevaluation of water distribution and oxygen mass transfer in sponge support media for a down-flow hanging sponge reactor
a down-flow hanging sponge (dhs) reactor has been developed for sewage treatment, mainly in developing countries. this novel reactor employs polyurethane sponge material as a support medium, which promises a proliferation of a large amount of biomass, offering excellent pollutant removal capability. three types of sponge medium were evaluated with respect to water distribution and oxygen mass t...
