  • Laboratory-scale anaerobic sequencing batch reactor for treatment of stillage from fruit distillation

    This work describes batch anaerobic digestion tests carried out on stillages, the residue of the distillation process on fruit, in order to contribute to the setting of design parameters for a planned plant. The experimental apparatus was characterized by three reactors, each with a useful volume of 5 L. The different phases of the work carried out were: determining the basic components of the ...

  • What’s the difference between distilled and deionised water?

    “Pure” water is used in all types of laboratories for a range of uses – from making up calibration standards to cleaning and even in the rinse cycle in some laboratory glasswashers for a pure clean. There are different types of purified water available – but what is the difference? Distilled water Distilled water is simply made by heating water to ...

  • Recovery and Distillation of Used Wash Solvent: Wattyl Australia

    It took Wattyl Australia just one year to recoup a $100,000 investment in a distillation unit that recovers solvent used in cleaning tanks and equipment in plants manufacturing solvent-based paints. It is now enjoying the ongoing savings as an addition to its bottom line. Instead of paying someone to dispose of the valuable solvents, the company is recovering 90% of the solvent and using it to ...


  • Brackish water treatment for reuse using vacuum membrane distillation process

    The availability of fresh water is vital for all human activities and in particular for improving living conditions, health and overall well-being. Pressure on scarce fresh water resources can be reduced by treating and reusing brackish water by advanced membrane treatment technologies. In this study, brackish water originating from effluent discharge of a local coal mine, seawater, groundwater ...

  • Effect of Leaching from Filters on Laboratory Analyses of Collective Organic Constituents

    Membrane and glass fiber filters are widely used in laboratory water and wastewater analyses. During sample filtration, some filters release organic compounds, which may interfere with organic analyses. This research investigated the interferences due to organic leaching in the determinations of dissolved organic carbon, biodegradable dissolved organic carbon, soluble biochemical oxygen demand, ...

  • Recycling of Fly Ash Produced in Combustion of Brown Coal with Increased Germanium Content

    A possibility of utilization of fly ash resulting from combustion of Czech brown coal with increased germanium content in a circulation fluidised bed combuster is examined in this study to recover germanium chloride. The laboratory measurement presented in this paper was focused on three aspects: obtaining raw germanium chloride by its direct distillation from the suspension of fly ash and HCl; ...


  • Procedure for calibration of micropipettors

    PURPOSE: Good Laboratory Practice dictates that all equipment used for the generation, measurement or assessment of data shall be adequately tested, calibrated and/or standardized. A procedure describing a pipettor calibration method, records of test performance and repairs should be available for laboratory personnel. This procedure describes a method for evaluating the accuracy and ...


  • Cetane Number and Cetane Index

    This article summarises the findings of an Energy Institute (EI) sponsored Technical Development Project carried out by Cliff Lilley Consultancy, and outlines a review of the suitability of the current cetane index equation used in IP 380 Calculation of Cetane Index of middle distillates by the fourvariable equation (EN ISO 4264) (ASTM D 4737 procedure A**) for calculating Cetane Index (CI), to ...

  • Stainless steels within desalination for reliable water supply

    To assure sustainable water production, the materials used in desalination plants need to perform for many decades without failures. During the last years, duplex - austenitic-ferritic - stainless steels have been selected for several desalination projects due to their unique combination of mechanical properties and corrosion resistance. Price stability of those grades, as a consequence of a ...

  • Field trial of a new commercially available diffusive ground-water sampler

    Field trials of a new commercially available diffusive ground-water sampling device were conducted at two industrial properties in the Blue Ridge Province of North Carolina. The test sites have extensive monitoring well networks and more than five years of historical water quality data. Volatile organic compounds (VOCs) including purgeable aromatics (petroleum hydrocarbons) and halogens ...

  • Low cost processes for the removal of phosphates in water and wastewater

    This paper presents a synopsis of various low-cost techniques employed for the removal of phosphates from water and treated wastewater. Techniques employed include seawater flocculation and coagulation/flocculation using bittern, adsorption on fluidised raw dolomite bed, and filtration through iron and aluminium coated filter media. Seawater flocculation at a seawater concentration of 10% ...

  • The sulphur–iodine and other thermochemical process studies at CEA

    The thermochemical sulphur–iodine process is studied by CEA with the objective of massive hydrogen production using the heat coming from a high temperature reactor. A two-fold programme was set up in 2000. The main part is devoted to the study of the basic process, including optimisation of a detailed flow-sheet, thermodynamics measurements and industrial plant evaluation. In parallel, an ...

  • Industrial Wastewater Treatment: Priority pollutant behaviour in on-site treatment systems for industrial wastewaters

    The majority of wastewaters deriving from the chemical industry consist of aqueous discharges produced during the physico-chemical processing of synthetic mixtures involving operations such as filtration, centrifugation, extraction and/or distillation. The wastewater streams, referred to as ‘process waters’ can include mother liquors, washing waters from the purification of products, ...
