  • Modeling of an IFAS Process with Fungal Biomass Treating Pharmaceutical Wastewater

    The project involved the dynamic modeling of a wastewater treatment plant (WWTP) treating pharmaceutical wastewater. The WWTP uses an integrated fixed-film activated sludge (IFAS) process with suspended carriers for biological treatment. The plant is unique in that it uses both fungal and bacterial IFAS reactors. The fungal biomass has been shown in laboratory testing to degrade a portion of the ...

  • Mathematical models for biomass in membrane-BNR process for wastewater treatment

    The equation of biomass is related to the mass-balance equation of substrate. This equation of substrate is expressed according to a model using the Monod equation, which indicates some limits for calculating the amounts of VSS in the MBR process. Some degradation of biomass which is caused by long SRT might result in the generation of substrate based on COD. Research was conducted by lab-scale ...

  • Different Process Configurations for Biomass-Carrier-Based Treatment of Industrial Wastewater

    IntroductionBiological treatment is still the most cost effective method to oxidize organic pollutants in wastewater. However, industrial wastewaters from different sources vary widely in composition. In some cases, the wastewater composition might prevent biological treatment by itself to meet effluent requirements. This work presents several different case studies: in laboratory, pilot and full ...

  • Biosorption of strontium by Padina sp. algae biomass: process optimisation and equilibrium study

    Biosorption of strontium by Padina sp. algae from aqueous solutions was studied. A response surface methodology (RSM) was employed to optimise the biosorption parameters. The effects of pH, initial metal concentration in solution, biomass dosage and temperature on the strontium uptake by the algae were investigated. RSM analysis showed that the experimental data were adequately fitted to ...

  • Comparison of Biomass Selection Between a Novel Membrane Bioreactor and Activated Sludge Process

    ABSTRACTThis study examined the performance of a novel type of submerged membrane bioreactor (MBR) system which utilizes polyethylene membrane of bigger pore size (mean around 18- 28μm) than normal MBRs. The system utilizes plate and frame structure with gravitational effluent flow. Two such bench scale MBR systems (0.084m3 of mixed liquor volume each) with membrane thickness of 0.48cm and ...

  • Cellular ATP – A Superior Measure of Active Biomass for Biological Wastewater Treatment Processes

    Biological wastewater treatment processes harness the ability of microorganisms to break down and assimilate organic compounds that, if left untreated, cause detriment to the environment. Although this process occurs naturally, engineered systems are used to accelerate the process by optimizing bioreactor conditions to promote higher-than-typical biomass concentrations, thus increasing the rate ...

  • Flexibility with biomass size reduction

    With increased global demand for biomass as a renewable energy source, engaging in profi table and effi cient biomass handling has become priority No. 1 for processing plants worldwide. The equipment used to carry out the strict production requirements of chipping, grinding, shredding and conveying the wood chips is vital to the design and tonnage estimations of engineers. Choosing the right ...

  • A pilot study on suspended activated sludge process augmented with immobilized biomass for simultaneous nitrification and denitrification

    Concurrent nitrification and denitrification (CND) are natural phenomena in the soil environment that can be applied in wastewater treatment for enhanced total nitrogen removal. However, significant renovation is necessary for existing plants to equip them for nutrient removal. At a domestic wastewater treatment plant, we performed a pilot test by installing bioplates with entrapped biomass in a ...

  • Impact of some herbicides on the biomass activity in biological treatment plants and biodegradability enhancement by a photo-Fenton process

    In recent years, the use of agrochemicals has increased because they are essential for profitable agricultural production. Herbicides are heavily demanded compounds and among these, the most marketed are 2,4-D, atrazine and acetochlor. They have characteristics that can cause problems to humans and the environment. Therefore, it is necessary to design systems that can reduce these compounds to ...

  • Fixed biomass process and its resistance to elevated copper loads during carbon removal and nitrification of industrial wastewater

    Metal compounds such as copper are known to be inhibitory or toxic to biological activity within wastewater treatments when reaching a certain threshold concentration. Little information on threshold values can be found for biofilm process like Biological Aerated Filters (BAFs). In this study, a BAF pilot plant (Biostyr®) for carbon removal and nitrification was operated to study its response to ...

  • Applying ERP to the biomass supply chain

    Green alternatives to hydrocarbon-based fuels are increasingly derived from recycled waste materials, including paper and packaging materials; residues from other industrial processes, and perhaps most importantly, biomass. Biomass comprises plant waste and plant by-products, and currently represents one of the most exciting avenues of research in the development of alternatives to fossil fuels. ...

  • Process-generated contaminants

    Overview: There is not currently a formal and universally recognised definition of a process-generated substance. Process-generated contaminants can be generated as emissions from combustion processes, abrasion and/or other processes that physically or chemically degrade or otherwise modify the starting material(s), e.g. degradation/composting of organic materials. Such ...

  • Using ATP to Measure Living Biomass in Wastewater

    Bioreactors harness the ability of naturally-occurring microorganisms to break down environmental contaminants discharged from cities and industries. Becasue they are the engine driving the process, it is critical to closely monitor the quantity and quality of these microorganisms.  2nd Generation ATP provides wastewater treatment operators with the ultimate tool for accurately measuring ...
