  • 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 ...

  • Simulation of oxidation processes and biomass growth in intermittent sand filter

    Infiltration percolation is an extensive treatment process aimed at eliminating organic pollution, oxidizing ammonia and removing pathogens. The main purpose of this work was to improve, by means of a numerical model, the understanding of oxidation processes and biomass development in an intermittent sand filter. Hydrodynamic, dispersion and biologic parameters were calibrated and validated after ...

  • 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 ...

  • 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 ...

  • 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 ...

  • What is Biomass Pellets Energy

    Biomass pellets energy means the energy made from biomass. What is biomass? Biomass refers to all the organic matters that store energy from photosynthesis. Therefore biomass in most cases means plants instead of animal. What is the chemical composition of biomass? Biomass is carbon based, so it contains ...


  • 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 ...

  • Biomass Briquette Machine

    Biomass Briquette Machine Introduction The biomass briquette machine is mainly used in processing agricultural residue like straw, rice straw, peanut shell, corn cob into solid briquettes in advanced technology. Briquetting is closely related to pelleting except that lager size stick fuel over 30mm named as briquettes. Our briquettes machine assists in clean burning and achieves biomass ...

  • Biomass energy outlook

    Over the last three or four weeks, my newsletter, Burning Bio News, has been oddly extreme. Timothy Searchinger, Princeton University, is churning out more antibiofuel hearsay. Dennis Avery, Hudson Institute, was in the news again putting a counter-spin on climate change. The U.S.EPA released its proposed rule for regulation of Greenhouse Gases (GHG) that includes industrial facilities that emit ...

  • Production of synthetic gasoline and diesel fuels by alternative processes using natural gas, coal and biomass: process simulation and economic analysis

    The problem of producing synthetic liquid fuels by alternative routes is addressed. Industrial processes known as Gas To Liquid (GTL), Coal To Liquid (CTL) and Biomass To Liquid (BTL) are considered: they use natural gas, coal and biomass as feedstocks, respectively. By means of process simulation, it is shown that the fuel produced on a weight basis per unit of feedstock (natural gas, coal and ...
