  • Continuous treatment of flotation collector wastewater using a membrane bioreactor

    Aniline aerofloat (DDA) is a widely used material in China and has become a main pollutant in floatation wastewater. In this study, a membrane reactor (MBR) was constructed to continuously treat simulated wastewater contaminated with DDA. The study investigated the hydraulic retention time (HRT) and the impact of influent DDA concentration on MBR performance, and analyzed intermediates from ...

  • The Evolution of Collector Monitoring Systems

    The vast majority of chain and flight collectors in operation throughout the world do not have any form of monitoring system installed to protect against operational failure. Traditional safety devices consist of a shear pin sprocket device, with a limit switch, designed to protect the drive system if a load or torque exceeds the working load of the  ...

  • Wastewater Monitoring in Akouedo/Abidjan, Cote d´ Ivoire with Gaiasafe Passive Collectors (PC)

    Abstract Contamination load and distribution of contaminants is shown. Gaiasafe Passive Collectors have been used successfully to determine single compounds out of the contamination load. Furthermore the spreading and biodegradation of contaminants was monitored over a large area in Abidjan. Only a few days after the dumping the chemical waste from Probo Koala was detected in the surface ...

  • Wastewater as anolyte for bioelectricity generation in graphite granule anode single chambered microbial fuel cell: effect of current collector

    Single chambered microbial fuel cell (sMFC) could be used for wastewater treatment as well as to generate electricity. Bioelectrochemical treatment of synthetic acetate based wastewater with simultaneous power generation was studied in tubular type air cathode sMFC. In order to improve the efficacy of MFC, three different anodic systems were considered such as graphite granules with graphite rod ...

  • Comparative evaluation of collectors for metal removal by precipitation/flotation

    This paper describes a comparative evaluation of collectors for metal removal by precipitation/flotation in samples of wastewaters from an electroplating industry. Precipitation/flotation was found to be successful over a great range of pH (3-12). The toxic metal ions lead (II), nickel (II), tin (II), iron (II) and aluminium (III) were stripped from contaminated industrial samples to ...

  • Biogas production and potential from U.S. Wastewater Treatment

    How many wastewater treatment plants (WWTPs) have anaerobic digestion? How many are utilizing the biogas? What percentage of these facilities are feeding additional substrates into their digesters? How is the biogas being used — is it flared, used to drive process machinery, heat the digester, or injected into a natural gas pipeline? These are some of the questions asked of the ...

  • Adaptive predictive expert control of dissolved oxygen concentration in a wastewater treatment plant

    In this paper we present the application of adaptive predictive expert controllers to dissolved oxygen (DO) control in the aerobic reactors of a wastewater treatment plant. The control system described in this paper consists of adaptive predictive expert control loops complemented by optimisation logic. The controllers successfully cope with nonlinearity and changing operating conditions of the ...

  • Estimating the costs of collective treatment of wastewater: the case of Walloon Region (Belgium)

    This paper contributes to a better understanding of costs for collective wastewater treatment in the Walloon Region (Belgium). Based on a large set of data, unit costs to population equivalents are modelled. Considering investment as well as exploitation costs, the model includes not only wastewater treatment plants but also collector and sewage networks in an integrated approach at the technical ...

  • Predicting wastewater temperatures in sewer pipes using abductive network models

    A predictive modelling technique was employed to estimate wastewater temperatures in sewer pipes. The simplicity of abductive predictive models attracts large numbers of users due to their minimal computation time and limited number of measurable input parameters. Data measured from five sewer pipes over a period of 12 months provide 33,900 training entries and 39,000 evaluation entries to ...

  • Conception and optimization of a membrane electrode assembly microbial fuel cell (MEA-MFC) for treatment of domestic wastewater

    A membrane electrode assembly (MEA) for microbial fuel cells (MEA-MFC) was developed for continuous electricity production while treating domestic wastewater concurrently. It was optimized via three upgraded versions (noted α, β and γ) in terms of design (current collectors, hydrophilic separator nature) and operating conditions (hydraulic retention time, external resistance, aeration rate, ...

  • AERZEN provides energy efficient process air generation in the Kötz wastewater treatment plant

    The Kötz wastewater treatment plant, located a few kilometres south of Günzburg, was designed for a population equivalent of 45,000. About 20,000 inhabitants are connected at present. Due to the additional discharge of industrial wastewater, the average daily load corresponds to a population equivalent of about 35,000. The wastewater treatment plant works according to the ...

  • A pilot scale electrolytic unit for tertiary treatment of industrial effluents

    Over the past few years, academic research has focused on the development of new treatment technologies for municipal and industrial wastewater that will be suitable for reuse. In this study, an electrolytic pilot scale unit has been manufactured for the tertiary treatment of biologically processed wastewater aiming at its reuse for groundwater recharge or for agricultural purposes. The ...

  • Membranes and theoretical modelling of liquid–gas membrane separation for aromatic compounds removal from water: a review

    Liquid–gas membrane separation techniques - namely, vacuum membrane distillation, membrane air–stripping/sweeping and pervaporation - are non–equilibrium membrane separation processes emerging for the removal of aromatic compounds from industrial wastewater and polluted ground waters. This review focuses on polymeric hydrophobic membranes which are commonly employed in the liquid–gas membrane ...

  • Flotation separation of strontium via phosphate precipitation

    Flotation separation of strontium (Sr) from wastewater via phosphate precipitation was investigated. While 37.33% of Sr precipitated at highly alkaline pH in the absence of PO43−, it completely precipitated as Sr3(PO4)2 at a molar ratio ([PO43−]:[Sr2+]) of 0.62 at a lower pH value. The presence of Ca2+ hindered ...
