  • Separation of emulsified crude oil in saline water by flotation with micro- and nanobubbles generated by a multiphase pump

    The flocculation–column flotation with hydraulic loading (HL, >10 m h−1) was studied for the treatment of oil-in-water emulsions containing 70–400 mg L−1 (turbidity = 70–226 NTU) of oil and salinity (30 and 100 g L−1). A polyacrylamide (Dismulgan, 20 mg L−1) flocculated the oil droplets, using two floc generator reactors, with rapid and slow mixing stages (head ...

  • Evaluation of microbial population and attachment study during bio–heap leaching at Malanjkhand copper project

    Microbial analysis of a 2X1000–tonne bio–heap leaching plant of Malanjkhand copper ore was done. Continuous monitoring of the micro–organism profile was done through conventional methods. The evolution of microbial population was done at quarterly intervals. The bacterial cultures were allowed to grow on Feo medium and FeSo medium. Three iron–oxidising acidophiles, namely, ...

  • Verifying the Use of Specific Conductance as a Surrogate for Chloride in Seawater Matrices

    ABSTRACT Coastal groundwater supplies, when overused, are particularly vulnerable to chloride contamination due to their close proximity to saltwater. Bevated chloride concentration in groundwater isthe most commonly used indicator of saltwater intrusion in coastal aquifers. Father well-defined relationships of specific conductance (SC) to chloride exist (Hem 1992: Christensen et al. 1999). ...

  • Polypyrrole incorporating biomolecules

    Polypyrrole (PPy) is a conducting polymer with emerging applications in biomedical engineering. We report on the synthesis and properties of PPy incorporating biomolecules using AC impedance spectroscopy. Impedance behaviour was consistent with two basic charge transfer processes, polaronic and electronic, demonstrated by two-electrode impedance spectroscopy over the frequency range 5 Hz?13 MHz. ...

  • Solvothermal synthesis and microstructure of TiO
    2
    nanowires on transparent conducting oxide substrate

    TiO2 nanowires were synthesised directly on FTO by solvothermal method. X–ray diffraction (XRD), field–emission scanning electron microscopy (FE–SEM) and high–resolution transmission electron microscopy (HRTEM) were used to characterise the TiO2 nanowires. The TiO2 nanowire formation was critically ...

  • Determining the fate of Microcystis aeruginosa cells and microcystin toxins following chloramination

    The cyanobacterium Microcystis aeruginosa can produce potent toxins known as microcystins. While many studies have focussed on the chlorination of microcystin toxins, little work has been conducted with respect to the chloramination of the microcystins. In addition, no studies have been reported on the effect of chloramination on intact Microcystis cells. This study was conducted ...

  • Prediction of flux decline during membrane filtration of leather plant effluent

    A membrane-based scheme has been proposed for the treatment of leather plant effluent. The effluent coming out from the various steps of leather plant are combined and Nanofiltration (NF) and Reverse Osmosis (RO) are adopted. Performances of two NF membranes are evaluated. Experiments are conducted using an unstirred batch cell. It is observed that a combined operation of NF using 400 MWCO ...

  • Combined electrocoagulation and electro-oxidation of industrial textile wastewater treatment in a continuous multi-stage reactor

    A combined electrocoagulation (EC) and electrochemical oxidation (EO) industrial textile wastewater treatment potential is evaluated in this work. A fractional factorial design of experiment showed that EC current density, followed by pH, were the most significant factors. Conductivity and number of electrooxidation cells did not affect chemical oxygen demand degradation (DCOD). Aluminum and ...
