  • Silica Treatment in Residential Applications

    This article is going to explore silica in water and how to treat the water for silica removal. Silicon dioxide is one of the most abundant compounds on earth and having such a high amount of it makes for no surprise that nearly all water contains colloidal and dissolved silica in solution unless it is treated. Silica is a glassy mineral substance that comes in a variety of forms. It is ...

  • Anglo Coal - Case Study

    Acidic mine water treatment without lime South African Coal Estates (SACE) is a division of Anglo Coal and operates the coalmine at Landau Colliery in South Africa. Processing of the coal results in a sulphate-rich effluent. Part of the sulphate is removed with lime precipitation but this produces an effluent that is oversaturated with gypsum. As a result, scaling occurred ...

  • New Advances in XRF Technology Allow for Measurement of Electroless Nickel Plating

    Electroless nickel (EN) plating was introduced over 50 years ago as a means to provide lightweight materials for improved fuel efficiencies, greater corrosion performance and durability. Quickly implemented into the automotive, aerospace and transportation industries, it was also seen as an alternative to plating with chrome, ...

  • ADM1 modelling of large-scale covered in-ground anaerobic reactor treating sugarcane vinasse

    In this paper, we demonstrate in a clear procedure the application of the Anaerobic Digestion Model No. 1 (ADM1) to model a large-scale covered in-ground anaerobic reactor (Cigar), processing sugarcane vinasse from a biorefinery in Brazil. The biochemical make-up (carbohydrates, proteins, and lipids) of the substrate was analysed based on the food industry standards. Two distinct subsets of ...

  • Pesticide removal through wastewater and advanced treatment: full-scale sampling and bench-scale testing

    Dieldrin and DDx removal through wastewater treatment, ozonation, and microfiltration was assessed for a water reuse project for groundwater replenishment in Monterey, California, USA. Full-scale sampling was conducted at the wastewater treatment plant, and physical wastewater treatment processes, ozonation, and microfiltration were tested at the bench scale. Removals observed through ...

  • Inhibition of Daphnia magna's occurrence in drinking water treatment process by controlling its phototactic behavior

    Cladocera zooplankton as carriers of bacteria result in biological risk due to their occurrence in drinking water treatment systems. In this paper, bench-scale experiments were performed to investigate the inhibition effect on Daphnia magna (D. magna) by controlling its phototactic behavior. The results showed that UVA had a negative effect on the phototaxis of D. magna, ...

  • Application of image processing on struvite recovery from swine wastewater by using the fluidized bed

    Fluidized granulation is one of the common methods used in wastewater treatment and resource recovery with harvesting millimeter-scale large particles. Presently, effective methods are lacking to measure the fluidized granules ranging from micro- to millimeter scales, with the consequence of ineffectively controlling and optimizing the granulation process. In this work, recovering struvite ...

  • Study of aggregation in surface sludge deposits from 14 full-scale French constructed wetlands using particle size distribution and dynamic vapor sorption analyses

    French vertical flow constructed wetlands (French VFCWs) are widely used for the treatment of wastewaters from small communities. In the system, unsettled wastewater is percolated through two successive stages of filter-cells planted with reeds. This causes the formation of a surface sludge layer. This layer plays positive roles in the treatment performance, but also leads to clogging. The ...

  • Scaling up and kinetic model validation of Direct Black 22 degradation by immobilized Penicillium chrysogenum

    This research was undertaken to develop tools that facilitate the industrial application of an immobilized loofah–fungi system to degrade Direct Black 22 (DB22) azo dye. In laboratory-scale tests, the DB22, and loofah as support, were used. Assays without loofah were used as a free-cells control. The use of natural carriers to facilitate adhesion and growth of the fungi has shown favorable ...

  • Scaling of nanofiltration membranes used for chromium(III) ions recovery from salt solutions

    The effect of membranes' structure on the efficiency of chromium(III) ions recovery from salt solution at low pH and the efficiency of chemical cleaning of these membranes were analyzed in this work. The nanofiltration membranes (DL and HL) used in this study were provided by GE Osmonics. The DL membrane had an irregular, dense support layer structure, while the HL membrane had a loose one. In ...

  • Impact on nitrifiers of full-scale bioaugmentation

    Nitrifiers are the slowest growing bacteria used in conventional biological wastewater treatment. Furthermore, their growth rate is seriously hampered by low temperature. As a result, the volume needed for nitrification dominates the volume of the biological reactors at a wastewater treatment plant. As a way of enhancing nitrification and reducing this volume, bioaugmentation can be used. ...
