  • Waste Water Batch Treatment System

    Industrial Wastewater Treatment Batch Treatment Systems (BTS) are intended for lower daily volumes of wastewater typically less than 10,000 gallons per day and designed to “batch” treat wastewater from start to finish at one time. In a batch treatment system, a volume of wastewater is gathered, treated by chemical / physical / biological means, and discharged. Storage ...

  • 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 ...


  • Sequencing batch reactor

    Sequencing batch reactors (SBR) sequential batch reactors are industrial processing tanks for the treatment of wastewater. SBR reactors treat waste water such as sewage or output from anaerobic digesters or mechanical biological treatment facilities in batches. Oxygen is bubbled through the waste water to reduce biochemical oxygen demand (BOD) and chemical oxygen demand (COD) to make suitable for ...

  • 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 ...


  • Treatment of thermomechanical pulping condensate using thermophilic and mesophilic sequencing batch reactors

    In-mill thermophilic treatment of individual wastewater streams to achieve water system closure has received much attention in pulp and paper mills. Aerobic biological treatment of thermomechanical pulping (TMP) condensate was conducted using thermophilic (55°C) and mesophilic (35°C) sequencing batch reactors (SBRs) for a period of 143 days at a cyclic time of 6, 8 and 12 h. A soluble chemical ...

  • Synthetic dairy wash-water treatment by using an alternating pumped sequencing batch biofilm reactor

    The performance of an alternating pumped sequencing batch biofilm reactor process in synthetic diary wash-water treatment was studied. The system comprises two reactors with two identical plastic biofilm modules. Two centrifugal pumps, one connected to each reactor, alternately move the water from one reactor to the other one, resulting in aeration. At three loading rates (336, 501 and 1080 g ...

  • Biodegradability of industrial textile wastewater – batch tests

    Following new trends we applied oxygen uptake rate (OUR) tests as well as long-term tests (in two batch bioreactors systems) in order to assess the biodegradability of textile wastewater. Effluents coming from a dyeing factory were divided into two streams which differed in inorganic and organic contaminants loads. Usefulness of the stream division was proved. Biodegradation of the low-loaded ...

  • 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 ...

  • Optimization of operation conditions for domestic sewage treatment using a sequencing batch biofilm filter

    A sequencing batch biofilm filter (SBBF) was applied to treat domestic sewage. The bioreactor consisted of fibrous filler in the upper part and ceramsite filter media in the lower part. The impacts of the most important factors including dissolved oxygen (DO), water temperature and hydraulic retention time (HRT) were evaluated on contaminants removal during the operation of the SBBF. Changes ...

  • Contaminant removal in septage treatment with vertical flow constructed wetlands operated under batch flow conditions

    Individual septic tanks are the most common means of on-site sanitation in Malaysia, but they result in a significant volume of septage. A two-staged vertical flow constructed wetlands (VFCWs) system for the treatment of septage was constructed and studied in Sarawak, Malaysia. Raw septage was treated in the first stage wetlands, and the resulting percolate was fed onto the second stage ...

  • Field trial of an automated batch chlorinator system at shared water points in an urban community of Dhaka, Bangladesh

    Point-of-use water treatment with chlorine is underutilized in low-income households. The Zimba, an automated batch chlorinator, requires no electricity or moving parts, and can be installed at shared water points with intermittent flow. We conducted a small-scale trial to assess the acceptability and quality of Zimba-treated municipal water. Fieldworkers collected stored drinking water over a ...
