Plant Profile - Warrenton Wastewater Treatment Plant Sequential Batch Reactor

The Warrenton (Ore.) Wastewater Treatment Plant is brand new. In fact, it initiated full operation Jan. 2, although the plant has been utilized since June 28, 2006. The sequencing batch reactor (SBR) plant was constructed on top of an existing facultative sewer lagoon site. The site conditions prohibited deep excavations, so the three basins for the SBRs are shallow, at only 12.5 ft (3.8 m), with ...

Starndard Batch Treatment of Free and Soluble Oil Wastewater

Small and Medium metal-based manufacturing plants produce between 1,000 and 30,000 gallons per week of oil-laden wastewater. Typically, the oil load is less then 2,000mg/l as soluble oil. Free (globular) oil is typically removed by DAF, oil-water separator, or coalescer with the remaining soluble oil needing to be reduced to less then 100mg/l in order to discharge directly to the local sewerage ...

Grease waste and sewage sludge co-digestion enhancement by thermal hydrolysis: batch and fed-batch assays

Grease waste (GW) is an adequate substrate for sewage sludge co-digestion since, coming from a waste water treatment plant, it has a high methane potential (489 NmLCH4/gVSin); however, no synergistic effect takes place when co-digesting with 52%VS grease. Conversely, thermal hydrolysis (TH) improves the anaerobic digestion of GW (43% higher kinetics) and biological sludge ...

Sequencing Batch Reactor Versus Continuous Flow Process for Pilot Plant Research on Activated Sludge

The objective of this article is to compare the advantages and disadvantages of the sequencing batch reactor (SBR) versus the more conventional continuous flow reactor (CFR) setup for pilotplant studies. The SBR process can offer many superior features for research applications. The control of operational conditions is more reliable, precise and versatile. Data collection by sampling and on-line ...

Taming taste and odor (T & O) problems in a water treatment plant

Taming Taste & Odor (T&O) Problems Some taste and odors are caused by mineral constituents in the water, e.g. excess chlorine and hydrogen sulfide. However the majority of taste and odor are the result of biologic activity. Spring turnover of lakes and algal blooms are responsible for Blue-green algae (Cyanobacterium), Green algae and diatoms that introduce filter clogging organisms ...

Virus elimination in activated sludge systems: from batch tests to mathematical modeling

A virus tool based on Activated Sludge Model No. 3 for modeling virus elimination in activated sludge systems was developed and calibrated with the results from laboratory-scale batch tests and from measurements in a municipal wastewater treatment plant (WWTP). The somatic coliphages were used as an indicator for human pathogenic enteric viruses. The extended model was used to simulate the virus ...

Treatment of odour containing hydrogen sulphide released from pharmaceutical wastewater treatment plant with SBR process by bio-trickling filter

In order to check the removal efficiency of odour containing Hydrogen Sulphide (H2S) from Sequencing Batch Reactor (SBR) process at lower temperature, deodorisation experiment was carried out for four months at pharmaceutical wastewater treatment plant in winter by the bio-trickling filter packed with ZX01 stuffing. The results suggested that the removal efficiency of H2S was higher than 98% and ...

Retention of 2,4,6-trinitrotoluene and heavy metals from industrial waste water by using the low cost adsorbent pine bark in a batch experiment

Pine bark is a low cost sorbent originating from the forest industry. In recent years, it has been found to show promise as an adsorbent for metals and organic substances in contaminated water, especially landfill leachates and storm water. This study aims to investigate if pine bark can replace commercial adsorbents such as active carbon. An industrial effluent, collected from a treatment plant ...

Treatment of Sludge Return Liquors: Experiences from the Operation of Full-Scale Plants

ABSTRACTMore stringent effluent criteria with regard to nitrogen call for improved nutrient removal techniques in wastewater treatment plants (WWTPs). Besides optimisation of the liquid treatment train of the plants, over the last years, attention has increasinly centred on the problem of return flows from sludge treatment. Depending on sludge handling and treatment, some 15 to 25 % of the ...

Model-Based Optimum Design of Sequencing Batch Reactors for Cod and Nitrogen Removal from a Slaughterhouse Wastewater

ABSTRACTA dynamic model of the activated sludge process was used to analyze and optimize the operation of an SBR treating slaughterhouse wastewater. The existing treatment cycle (duration of fill, aeration, mix, decanting and wasting periods) was found to be inadequate for meeting effluent requirements under a number of different loading scenarios. Modelling analysis indicated that the aeration ...
