  • Separation of huntite and hydromagnesite from magnesite in combination of Physicochemical Treatment and size reduction
    Ain Shams Engineering Journal, 2019
    Co-Authors: Hüsnügül Yilmaz Atay, Mustafa Çırak
    Abstract:

    Abstract Huntite and hydromagnesite are important minerals in the synthesizing of fire-safe composites. They are mostly not pure and associated with gangue minerals like magnesite, dolomite, aragonite and calcite. In this study, run of mine ore was subjected to the Physicochemical Treatment as a function of different size fraction. For observing the wetting behaviour, the contact angle measurements were carried out. It was found that the addition of Na-oleate rendered the particle surface hydrophobic and this finding confirmed the adsorption capability of this collector on the powdered sample. Flotation results indicated that the grade of huntite and hydromagnesite increased from 50% to 84% by decreasing the particle size of the mineral powder. The optimum degree of liberation was achieved at 38 µm. X-ray diffraction (XRD), Scanning Electron Microscopy (SEM) and Energy Dispersive Spectroscopy (EDS) were used to perform the phase analysis, surface morphology and elemental analysis of the mineral.

  • Progress in the Physicochemical Treatment of microalgae biomass for value-added product recovery.
    Bioresource technology, 2020
    Co-Authors: Jorge Alberto Vieira Costa, Bárbara Catarina Bastos De Freitas, Luiza Moraes, Munise Zaparoli, Michele Greque De Morais
    Abstract:

    Interest in microalgae-derived products is growing, mostly due to their unique characteristics and range of industrial applications. To obtain different products, one must employ specific preTreatments that retain the properties of the biologically active compounds extracted from microalgae biomass; thus, new extraction techniques require frequent upgrades. Due to increased interest in economically viable and ecologically friendly processes, new extraction methods that can be incorporated into microalgae biorefinery systems have become the main focus of research. Therefore, this review aims to address the potential applications, future prospects, and economic scenario of the new Physicochemical Treatments used in the extraction of bioactive microalgae compounds.

  • influence of hydraulic retention time in a two phase upflow anaerobic sludge blanket reactor treating textile dyeing effluent using sago effluent as the co substrate
    Environmental Science and Pollution Research, 2011
    Co-Authors: M Senthilkumar, G Gnanapragasam, V Arutchelvan, S Nagarajan
    Abstract:

    Purpose Textile dyeing and sago industries are the most polluting industries in South India, especially in industrial cities like Salem, Tamil Nadu, where textile dyeing and sago industries are clumped together geographically. Conventional Physicochemical Treatment followed by biological processes for the effluent generated from these industries are ineffective, costlier and produce huge quantities of hazardous sludge and harmful by-products which requires further Treatment and safe disposal. Hence, the development of an alternative Treatment method will become important. The main objective of this investigation is to establish a sustainable bioTreatment technology for the Treatment of textile dyeing effluent using sago effluent as co-substrate in a two-phase upflow anaerobic sludge blanket (UASB) reactor.

  • Physicochemical Treatment Processes for Water Reuse
    Physicochemical Treatment Processes, 2005
    Co-Authors: Saravanamuthu Vigneswaran, Huu Hao Ngo, Durgananda Singh Chaudhary, Yung-tse Hung
    Abstract:

    The continuing processes of industrialization and urbanization coupled with uncontrolled population growth, deforestation, and water pollution are exerting pressure on the planet’s limited freshwater resources. The need to recycle and reuse wastewater has been more and more realized, as the global supplies of clean water diminish and demand for water rises. Advanced wastewater Treatment is becoming an international focus for the rational use of scarce water resources, and as means of safeguarding aquatic environments from the harm caused by wastewater disposal. Conventionally, wastewater was discharged into the environment after removing the majority of suspended solids in primary Treatment and biodegradable organic substance in secondary Treatment. These Treatments are not sufficient to produce effluent of reusable quality. Now the trend is changing toward the total water recycle approach, which promotes ecological sustainability by managing the treated wastewater as a resource instead of a waste and, at the same time, reducing the demand for water from the existing water resources. Tertiary wastewater Treatment is therefore required to remove most of the remaining organics, solids, and pathogenic microorganisms.

  • Treatment of textile dye effluents using coagulation flocculation coupled with membrane processes or adsorption on powdered activated carbon
    Desalination, 2009
    Co-Authors: Farida Harrelkas, Abdelaziz Azizi, Abdelrani Yaacoubi, A Benhammou, Marie Noelle Pons
    Abstract:

    This study describes the Treatment of textile wastewater by various combinations of Physicochemical and membrane processes. The basic Physicochemical Treatment consists in coagulation/flocculation (CF) with different coagulant and flocculant concentrations. The parameters analyzed prior and after Treatment are turbidity, chemical oxygen demand (COD) and absorbance (Abs). The optimal process parameters for CF are 5 for pH, 100 mg/l for coagulant (Al2(SO4) 3) of 100 mg/l and 4 mg/l for flocculant. This simple Treatment by CF was inefficient concerning COD reduction and dyes deterioration. It was therefore combined with microfiltration (MF) or ultrafiltration (UF) on one hand and adsorption on powdered activated carbon (PAC) on the other. The CF/MF, CF/UF and CF/PAC combinations ensure a COD removal of 37%, 42% and more than 80% respectively and a color reduction of 65%, 74% and 50% respectively.
