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 ...

Removal of lead(II) and nickel(II) ions from aqueous solution via Bermuda grass biomass
Adsorption of lead(II) and nickel(II) ions from aqueous solutions was investigated by Bermuda grass biomass. The adsorption process was studied as a function of pH, initial metal concentration, temperature and time. The experimental data obtained were investigated via Langmuir, Freundlich and Temkin isotherms. The kinetic data were examined by pseudo-second-order and intraparticle diffusion ...

Biosorption of Ag+ from aqueous solution by Streptomyces rimosus biomass
The silver biosorption capacity of a Streptomyces rimosus biomass pretreated with NaOH was studied in the batch mode. Under optimal experimental conditions, a biosorption capacity of 63 mg Ag+ g−1 biomass was obtained. External mass transfer was found to be the controlling step in the overall sorption process. The equilibrium data poorly fitted the Langmuir and Freundlich model isotherms over the ...

Ammonium removal in landfill leachate using SBR technology: dispersed versus attached biomass
Large concentrations and oscillations of ammonium nitrogen (NH4+-N) in municipal landfill leachate pose considerable constraints to its further treatment in central wastewater treatment plants. The aim of this study was to evaluate and optimize two technologies for the pre-treatment of 600 L/day of landfill leachate: in particular, to optimize their operational conditions for NH4+-N removal ...

Nitrification of saline, inhibitory chemical effluents using LEVAPOR-carrier
Mixed effluents of chemical productions are comprising mainly of Mixtures of several type, often also inhibitory pollutants, respectively salinities characterised by fluctuating concentrations and qualities, resulting often in low rates and stabilities of nitrication processes, despite to efficient COD removals. Immobilisation of nitrifying biomass results generally in process improval. ...

Treatment of high strength aqueous wastes in a thermophilic aerobic membrane reactor (TAMR): performance and resilience
In the present work, the thermophilic aerobic membrane reactor technology was studied for the treatment of high strength aqueous wastes mainly containing dyes, surfactants and solvents. The thermophilic biomass resilience and the process stability under critical conditions (such as rapid rise of the mixed liquor pH, oxygen supply interruption, etc.) were also evaluated. The experimental work ...

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 ...

Resource assessment, logistical simulation, and risk quantification Of biomass supply
Taraneh Sowlati and co-authors Jamie Stephen, Shahab Sokhansanj, and Toni Bi researched biomass supply. Generally, in assessments of bioenergy potential, biomass supply is assumed to be constant over an extended period of time for a particular region. This assumption is not realistic in the context of agriculture, said Sowlati. “Because there has been little examination of supply reliability, we ...

Different process configurations for biomass-carrier-based treatment of industrial wastewater
KeywordsBiological wastewater treatment, Industrial wastewater, biomass carriers, case study 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 ...

Quantification of kinetic parameters for heterotrophic bacteria via respirometry in a hybrid reactor
Over the last decade new technologies are emerging even more for wastewater treatment. Among the new technologies, a recent possible solution regards Moving Bed Biofilm Reactors (MBBRs) that represent an effective alternative to conventional processes. More specifically such systems consist in the introduction of plastic elements inside the aerobic reactor as carrier material for the growth of ...

Agave Residue Shredder Machine
In Mexico, people use agave plants to make wine, which creates a lot of residue, which can pollute the environment when it is landfilled. Smart people thought of a direct way is to use these residues to generate electricity. Power plants require dry and uniformly sized materials, and AIShred biomass pretreatment systems and biomass shredders can continuously convert agave residues into qualified ...

Pellet Mill Report: A Complete Guide for Pellets Industry Beginners and Pellet Mill Buyers
What is a pellet mill? The definition A pellet mill (also called pellet machine, pellet press) is a type of mill or machine which is used to make pellets from powdered materials. A pellet mill is usually consisted of pellet die and rollers. The rotating rollers or the rotating dies force the feedstock trough the die holes to form pellets. (See the picture of how the pellets are produced by ...

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 ...

The role of colloidal and particulate organic compounds in denitrification and EBPR occurring in a full-scale activated sludge system
The efficiencies of denitrification and enhanced biological phosphorus removal (EBPR) in biological nutrient removal (BNR) activated sludge systems are strongly dependent on the availability of appropriate carbon sources. Due to high costs of commercial compounds (such as methanol, ethanol, acetic acid etc.) and acclimation periods (usually) required, the effective use of internal carbon sources ...
