    Sampling. Sludge samples were collected from two different refinery wastewater treatment plants of the petroleum producer Petrobras (Brazil). The first sludge sample, named MBR1 and originated from a laboratory-scale membrane bioreactor (2 L) (MBR), was performed with continued aeration and collected after a day period of high phenolic load feeding ( mg L-1), as previously described by Cited by:   Anaerobic digestion of waste activated sludge (WAS) is most commonly used at wastewater treatment facilities to stabilize the sludge. However, poor biodegradation efficiency of sludge and longer retention times (20–30 days) are the major limitations of anaerobic digestion method, which can be overcome by disintegrate the sludge and make intracellular material readily available to Cited by:

    Furthermore, the overall sludge yield of the MLE process of gTSS/gBOD was 40% lower than the full-scale plant at the same SRT of 17 days. St. Marys wastewater treatment plant employed a conventional activated sludge system with a primary clarification, and the MLE pilot process achieved a comparable effluent quality, albeit with much lower. The current study evaluates the performance of a pilot scale fed batch reactor (FBR), followed by coagulation and sand filtration, for the treatment of an oil refinery wastewater. The total reductions in COD, BOD, oil contents and phenol were %, %, % and %, respectively, with FBR followed by coagulation and sand filtration.

Pilot studies on enhancement of the refinery activated sludge process designed to meet effluent limitations were conducted for the American Petroleum Institute to determine if effluent quality obtained by such enhancement would be equivalent to that obtained from granular carbon adsorption originally proposed for Cited by: 1.

Aerobic bio-treatment of the refinery wastewater was carried out in a m 3 pilot-scale gas–liquid–solid three-phase flow airlift loop bioreactor (ALR) with a low ratio of height to diameter (s), in which biological membrane replaced the activated influences of pH value, air flow rate (AFR) and hydraulic residence time (HRT) on COD and ammonia nitrogen (NH 4 –N) reductions Cited by: Galil, N., Rebhum, M., A comparative study of RBC and activated sludge in biotreatment of wastewater from an integrated oil refinery.

Proceedings of the Forty-Fourth Purdue Industrial Waste by: A three-step pilot plant was designed, fabricated and tested for the treatment of highly contaminated petroleum refinery wastewater. The three-step process consisted of an electrocoagulation (EC.

Powdered activated carbon (PAC) adding to the activated sludge process can lead to a higher quality of treated wastewater, a more stable system and the production of reusable water. In this study, history, principles, mechanisms, and advantages of powdered activated carbon treatment (PACT) process File Size: 1MB.

activated sludge system. In this study, petroleum refinery wastewater was co-treated with municipal wastewater in continuous flow bench scale reactors. Two bench scale reactors, A and B each of liquid volume of 21 L treated municipal wastewater and a mixture of municipal and refinery wastewater, respectively.

The organicFile Size: KB. The activated Sludge Process is a biological treatment commonly used for treatment of urban and industrial wastewater. Its efficient application requires an effective control and supervisory system, and continuous enhancement of the process is still a research subject.

Laboratory and pilot tests were conducted to investigate the use of ionizing radiation at an activated sludge wastewater treatment facility with residuals processing. Operational enhancements were. In the activated sludge treatment process, the removal of suspended solids from wastewater is usually through gravity separation in a clarifier.

to determine feasibility of the ASSR process. The pilot-scale plant was seeded with activated sludge from the full-scale WWTP and treated raw sewage taken from the same municipal sewer system. Objectives Specific primary objectives of this investigation include studying the degradation of activated sludge within the ASSR process at the.

The CAS process has been the most commonly utilized biological treatment method in the petroleum refinery [3,4,17].In conventional biological processes, both the flow and composition changing of the wastewater can usually impede the treatment system [3,18,19,20].In some cases, common continuous flow processes such as CAS may encounter serious problems to meet the regulated discharge by: 3.

A MBR pilot plant, fed by mixed liquor of a full-scale activated sludge process from a municipal wastewater treatment plant, was operated dosing low PAC concentrations (0, 2, 5, 10 and 20 mgL−1, respectively).

Experiments were also carried out at two different temperatures corresponding to summer and winter by: the disposal sludge was mL. After 1 month of pilot run, the effluent COD data were close to each other, demonstrating the start up ending.

Three pilot-scale activated sludge units were operated in parallel with common pretreatment utilizing wastewater streams from a Class D refinery. Effluents from the following systems were tested: 1. Conventional Treatment: A conventionally operated activated sludge unit + final filtration.

The second major debate revolved around the fundamental activated sludge mechanism; whether it was a physical-chemical operation or a biological process.\u48,50\d Baly theorized that differential charging between sewage colloids and floc matrixes resulted in an electrostatic attraction and consequent clarification.\u48\d Along similar lines.
