Moving Bed Biofilm Reactor Performance in Phenol Removal from Wastewater
Background: Phenolic compounds are found in wastewater of many industries such as pulp and paper, textile, petrochemical, oil refineries, production of phenolic resins, plastics, coal furnace, tannery, rubber reclamation plant, fertilizers, coke, paints, rubber, decolorizer, resins, rubber and phenol- formaldehyde resin industries. This study aimed to evaluate Moving Bed Biofil...
متن کاملUtilizing algal oxygen production for advanced wastewater treatment in a Moving Bed Biofilm Reactor (MBBR) – the Biologically Aerated Reactor (BAR
A novel wastewater treatment system has been developed, utilizing an oxygen-rich algal liquid to supply oxygen to an aerobic biofilm reactor. Aerobic treatment of wastewater takes place in a Moving Bed Biofilm Reactor, where the aerobic biomass which breaks down organic and nitrogenous pollutants grows as a biofilm on floating carriers. Algae grown in an open raceway pond produce oxygen through...
متن کاملNitrogen Removal from Milking Center Wastewater via Simultaneous Nitrification and Denitrification Using a Biofilm Filtration Reactor
Milking center wastewater (MCW) has a relatively low ratio of carbon to nitrogen (C/N ratio), which should be separately managed from livestock manure due to the negative impacts of manure nutrients and harmful effects on down-stream in the livestock manure process with respect to the microbial growth. Simultaneous nitrification and denitrification (SND) is linked to inhibition of the second ni...
متن کاملEffect of influent nutrient ratios and hydraulic retention time (HRT) on simultaneous phosphorus and nitrogen removal in two-sludge sequencing batch reactor
A laboratory-scale anaerobic-anoxic/nitrification sequencing batch reactor (A2N-SBR) fed with domestic wastewater was operated to examine the effect of varying ratios of influent COD/P, COD/TN and TN/P on the nutrient removal. With the increased COD/P, the phosphorus removals exhibited an upward trend. The influent TN/P ratios had a positive linear correlation with the phosphorus removal effici...
متن کاملEffects of Solid Retention Time (SRT) on Sludge Characteristics in Enhanced Biological Phosphorus Removal (EBPR) Reactor
This study investigated the effects of solid retention time (SRT) on sludge characteristics and operational performance in enhanced biological phosphorus removal (EBPR) reactor. The results showed that the reactor operated at SRT of / = 8.3 d could achieve phosphate removal efficiency > 90 % and SVI < 100 mL g–1. In comparison, increasing SRT to / = 16.6 d led to a decrease of phosphate removal...
