  • Preparation of mesoporous TiO2 with enhanced photocatalytic activity towards tannery wastewater degradation

    Ordered mesoporous TiO2 materials are successfully synthesized via a sol-gel route using butyl titanate as a precursor and sodium dodecyl benzene sulfonate surfactants as soft templates. The as-prepared TiO2 samples possess a relatively high surface area of 40.03 m2/g and the center of pore diameter distribution of 13.04 nm. They exhibit excellent ...

  • Phytoremediation of chromium from tannery wastewater using local plant species

    Phytoremediation, which is an emerging technology for cleaning up contaminated sites, is cost effective and has aesthetic advantages and long term applicability. The technology involves efficient use of plant species to remove, detoxify or immobilize contaminants in a growth matrix (soil, water or sediments) through natural processes. For this study, swamp smartweed (Polygonum coccineum), ...

  • Low energy external MBR Sidestream Technology for industrial wastewater applications

    The need for water treatment and reuse is increasing globally and membrane bioreactor technology (MBR) is a proven technology to fulfill this. Fouling is still the limiting factor to run high performance and energy efficient installations. Berghof Membrane Technology produces tubular ultrafiltration membranes and modules for the use in sidestream MBR applications. The advantage of these tubular ...

  • Evaluation of genotoxicity and cytotoxicity of treated tannery wastewater in southern Brazil

    In this study, we analysed the genotoxic and cytotoxic effects of treated tannery wastewater using the micronucleus (MN) test in fish erythrocytes (Bryconamericus iheringii) and the Allium cepa test system. Fish were exposed to three different concentrations of tannery effluent (2, 5 and 10%) for 3 and 6 days. Onion bulbs were exposed to four dilutions of the effluent (2, 5, 10 and 25%) for 60 ...

  • Phytoremediation of chromium(VI)-laden waste by Eichhornia crassipes

    The aim of the present investigation is to develop a suitable phytoremediation technology for the procumbent removal of chromium(VI) in tannery wastewater. Water hyacinth species, Eichhornia crassipes, was chosen to remediate chromium from synthetic wastewater. Present study revealed 88% Cr(VI) removal in synthetic wastewater sample within 48 hours of the study at all concentrations ranging from ...

  • Recovery of proteins from wastewater of tannery beamhouse operations: influence on the main pollution parameters

    The recovery of proteins from effluents of beamhouse operations in a hair-pulping process of hides is proposed. Precipitation with sulphuric acid at the isoelectric pH was chosen for protein recovery. The precipitates were characterized in order to study their potential uses. Apart from the protein nitrogen, the precipitate also contained a considerable content of fats resulting from the ...

  • Biological waste management of leather tannery effluents in India: current options and future research needs

    This paper reviews the major biological treatment methods applied for tannery effluents in India. Anaerobic methods and activated sludge process have been the preferred treatment options. Sequencing batch reactor process holds promise for tannery effluents but the technology is yet to see the light of the day in India. Design of aerobic systems needs major overhaul through modelling approaches of ...

  • Treatment of tannery wastewater in a hybrid biological reactor

    A shaft-type hybrid bioreactor treated composite wastewater of a chrome tannery manufacturing 'wet-blue leather'. The sample was treated under suspended growth and then hybrid system with 20 g/L of 5 mm tyre tube beads in batch mode. The continuous study was made under suspended growth and hybrid system with 10-30 g/L of beads. The kinetic coefficients Ks, k, Y and k were 170.83 mg/L, 0.0397 h−1, ...

  • Pilot-scale studies on the treatment of tannery effluents by electroflotation

    A pilot-scale electroflotation system with a treatment capacity of 0.8 m³ per hour has been designed and built. The system is equipped with a conditioning tank, a rectifier, flow meters, an energy meter and pumps. Iron, aluminium and titanium coated with oxides of tantalum, ruthenium and iridium were used as electrodes. The system was installed within the premises of the Common Effluent Treatment ...

  • Use of waste whey in tanning industry

    The name of the deliming process suggests that the aim of the process is to remove the lime from the white hide. However, this is not complex enough. The primary purpose of the deliming procedure is to prepare the hide for bating and pickling. In order to do that, it is necessary to reach a suitable pH level to permit the bating enzymes to be active, and partially remove the excess lime. It is ...
