Effect of carrier fill ratio on biofilm properties and performance of a hybrid fixed-film bioreactor treating coal gasification wastewater for the removal of COD, phenols and ammonia-nitrogen
The purpose of this study was to determine the effect different biofilm carrier filling ratios would have on biofilm morphology and activity and bacterial diversity in a hybrid fixed-film bioreactor treating high strength coal gasification wastewater (CGWW) for the removal of chemical oxygen demand (COD), phenols and ammonia-nitrogen. Results showed that a carrier fill of 70% formed a ...

Laboratory-scale investigation of integrated biological phosphorus removal and mainstream deammonification at the Terrence J. O`Brien Water Reclamation Plant. Proceedings WEFTEC.17
Abstract: In collaboration with the Metropolitan Water Reclamation District of Greater Chicago (MWRDGC), the environmental biotechnology research group at Northwestern University (NU) is conducting a laboratory-scale investigation of enhanced biological phosphorus removal (EBPR) integrated with mainstream deammonification using primary effluent as feed. The research presented here includes (1) A ...

Synergistic application of advanced primary and secondary wastewater treatment systems
Published in Water and Waste Digest membrane issue, November 2008 Miroslav Colic; Chief Scientist, Clean Water Technology Inc., Los Angeles, CA To be published in Water and Waste Digest later this year The increased regulatory pressures and demand for reused water stimulated development of several new wastewater technologies in the last decade. Advanced treatment systems are characterized by ...

A comparative study of an up-flow aerobic/anoxic sludge fixed film bioreactor and sequencing batch reactor with intermittent aeration in simultaneous nutrients (N, P) removal from synthetic wastewater
The performance of two bench scale activated sludge reactors with two feeding regimes, continuous fed (an up-flow aerobic/anoxic sludge fixed film (UAASFF) bioreactor) and batch fed (sequencing batch reactor (SBR)) with intermittent aeration, were evaluated for simultaneous nutrients (N, P) removal. Three significant variables (retention/reaction time, chemical oxygen demand (COD): N ...

Partially aerated submerged fixed-film bioreactor for simultaneous removal of carbon and nutrients from high-strength nitrogen wastewaters: effect of aeration rate and C:N:P ratio
Influence of aeration rate and COD:N:P (C:N:P) ratio on the performance of an upflow partially aerated submerged fixed film (UP/ASFF) bioreactor for simultaneous carbon and nutrient removal from high-strength nitrogen wastewater was investigated during 6 months. Airflow rates at three levels of 1.5, 3, and 4.5 L/min and C:N:P ratios at four levels of 450:300:10, 450:150:10, 450:100:10, and ...

Treatment of high strength resin production wastewater case study
Problem Full-scale Incineration of this wastewater had proved very expensive due to the fuel input required and the ongoing incinerator maintenance costs. The polymer manufacturer sought treatment alternatives to save money. Initial biotreatment pilot work indicated that biotreatment was not feasible using conventional activated sludge technology even when the concentrated wastewater was diluted ...

A simulation of the fate of nitrogen in an on-site wastewater treatment system
An experiment to study and to build a mathematical model to reproduce the behavior of nitrogen in a residential wastewater treatment process was performed. A pilot unit receiving grey and black water was used. The pilot consisted in a septic tank followed by a fixed-film, partly aerated bioreactor with effluent recirculation operated under two different scenarios: normal operating conditions and ...

Trace organics removal using three membrane bioreactor configurations: MBR, IFAS-MBR and MBMBR
Seventeen pharmaceutically active compounds and 22 other trace organic pollutants were analysed regularly in the influent and permeate from a semi-real plant treating municipal wastewater. The plant was operated during 29 months with different configurations which basically differed in the type of biomass present in the system. These processes were the integrated fixed-film activated sludge ...

Wastewater Treatment Process
The wastewater treatment process is complex and critical to civilization. In simplest terms, wastewater is water that has been mixed with waste matter. Wastewater can be classified as domestic, municipal, or industrial based upon the source of generation. For instance, domestic wastewater comes from everyday liquid waste, including water used to flush the toilet, to shower, or to wash dishes. ...

Applications for UF Filtration Technology in Water & Wastewater
Water treatment technology is and can be applied to different municipalities, industries, and commercial businesses, each with their own specific water treatment needs. For this reason, it is beneficial to have technologies on hand that are versatile based on the treatment application. For instance, filters are used in almost every water/wastewater treatment application in either pretreatment or ...

Removing Ammonia in Drinking Water With AccuFAS
Read on to learn how, utilizing its pilot reactor, Brentwood helped a mid-sized suburban community assess potential treatment of ammonia in the city’s potable water source. What is Ammonia? Ammonia is a naturally occurring compound found in some chemical products, fertilizers, and as a byproduct of the degradation of organic materials such as manure and urine. Its high solubility means ...

Pros & Cons - Moving Bed Bioreactor Technology
A moving bed bioreactor is a biological wastewater treatment process. In many instances, wastewater is full of organic matter that can be difficult to filter out by chemical or physical means. Therefore, one of the best methods of dealing with organic matter is treating it with a biological process. The basic idea behind the biological water treatment processes is using micro-organisms to break ...
