  • Optimizing Wastewater Treatment

    ' Growing volumes of both industrial and municipal wastewater are being discharged to surface waters but the treatment provided frequently is inadequate to protect the desired uses of the receiving waters. With limited resources in terms of both institutional capacity and finance, governments face difficult choices in optimizing their investments in municipal systems and establishing practical ...

  • Effect of Enhanced Biochemical Processes in the Sewer Collection System on Influent Wastewater Characteristics and Wastewater Treatment Plant Performance

    Short Abstract (less than 100 words) In-Pipe Technology (IPT) employs sewer collection system bioaugmentation treatment to enhance the sewer biochemical processes by improving the microbiology in the collection system, and provides improved microbiology to the wastewater treatment plant (WWTP). In this presentation, the effect of IPT sewer collection system bioaugmentation on sewer ...

  • Advanced Lagoon Treatment Technologies for Wastewater Treatment

    Lagoon-based wastewater treatment systems are popular around the world for their simplicity and cost-effectiveness. However, these systems are unable to reliably remove biochemical oxygen demand (BOD) and total suspended solids (TSS) to less than 30 mg/L or achieve nitrification during winter months in cold climates. Several innovative modifications have been developed, which have the potential ...

  • Effective products for wastewater treatment system

    The process applied to alter waste water into dirt-free drinking water is called as WasteWater Treatment; the water that is no longer needed or fit for any purpose. The bilge water can be returned to the water cycle to make it suitable for drinking. This is called as water reclamation which avoids the disposal of wastewater by treating them with various recycling processes. Treatment implies ...

  • Wastewater Treatment Municipality Of Saint-Claude

    In Quebec, the municipalities must make sure that their rejections of sewerachieve the goals applied to the receiving medium. The Rotating BiologicalReactor (RBR), developed by the biological processes division of H2OInnovation, showed its effectiveness during more than one year testingproject, which contribute to the obtaining of the Standard Technology (CF-1) certification allowed by the Quebec ...

  • Suitability of ozone pre-treatment for amoxicillin wastewater

    This study deals with the ozonation of amoxicillin in real pharmaceutical wastewater and its efficacy as a pre-treatment, prior to biological degradation by a mixed culture of bacteria in a sequencing batch reactor (SBR). An ozone utilization of 0.27 g/g-COD (chemical oxygen demand) lowered the pH of the wastewater to 6.6, reduced the specific ultraviolet absorption by 43% and increased ...

  • Treatment of domestic wastewater by a hybrid natural system

    The present study addresses performance evaluation of a hybrid natural system comprising of settling tank, sand-gravel filter (SGF), aerated constructed wetland (ACW) and vermifilter (VF) for the treatment of domestic wastewater. The sequential batch experiments were conducted in a pilot-scale experimental set-up. The biochemical oxygen demand (BOD5) was varied from 20 to 120 mg/L and the ...

  • Mixing To Enhance Facultative Wastewater Lagoon Treatment

    SolarBee® & GridBee® Are Leading The Way In most lagoons, sunlight causes a hard stratification at 12 to 18 inches of depth.  The top water is warmer and thick algae populations are producing supersaturated dissolved oxygen (DO).  The DO gasses off at the surface and is not readily available deeper in the pond for use by BOD-reducing bacteria. Meanwhile new ...

  • Ozone pretreatment of olive mill wastewaters (OMW) and its effect on OMW biochemical methane potential (BMP)

    The possibility of coupling a physicochemical pretreatment (ozonation) with a biological treatment (anaerobic digestion) was investigated for the case of olive mill wastewaters (OMW). Batch ozonation experiments were performed in a glass bubble reactor. The parameters which were tested included the ozone concentration in the inlet gas stream, the reactor temperature and the composition of the ...

  • A study on ruthenium-based catalysts for pharmaceutical wastewater treatment

    Ruthenium-based catalysts were prepared by a saturation-dip method. Their catalytic activity was evaluated by a catalytic wet oxidation (CWO) process. The ruthenium-based catalysts were used to purify organic pharmaceutical wastewater with high concentration pyridine and pyridine derivatives that have high chemical oxygen demand (COD). In the CWO process, organic pharmaceutical wastewater was ...

  • Fungal Based Treatment for Nitrogen and Phosphorus Decrease in Wastewater

    Biological nutrient removal (BNR) technology can suffer poor performance or complete failure due to the fastidious nature of the bacteria used in the system. The bacteria involved necessitate strict operating conditions, multiple zones with one or more recycling lines, carbon source augmentation, and efficient aeration. For wastewater treatment plants receiving significant combined sewer ...

  • Biological treatment of pharmaceutical wastewater from the antibiotics industry

    Pharmaceutical wastewater generated by an antibiotics (penicillin) company was treated by aerobic membrane bioreactors (MBRs) and sequencing batch reactors (SBRs). At a low organic loading rate of 0.22 kg-COD m−3d−1, both types of reactors were capable of treating the wastewater such that the treated effluent met the discharge regulation except for the total dissolved ...

  • Nitrogen removal in tertiary wastewater treatment plant of a chemical complex

    A Biochemical Contact Oxidation Film (BCOF) technique was piloted for the treatment of a secondary effluent of the Jilin Chemical Industry Corporation (JCIC). The original pulse contact flocculation clarifier used for the tertiary treatment was not performing to the discharge standards. Results show that NH3-N concentration was decreased from 30 mg/L to 15 mg/L, COD concentration was decreased ...
