  • Co-treatment of landfill leachate in laboratory-scale sequencing batch reactors: analysis of system performance and biomass activity by means of respirometric techniques

    Aged or mature leachate, produced by old landfills, can be very refractory; for this reason mature leachate is difficult to treat alone, but it can be co-treated with sewage or domestic wastewater. The aim of the study was to investigate the feasibility of leachate co-treatment with synthetic wastewater, in terms of process performance and biomass activity, by means of respirometric techniques. ...

  • Techniques for Oil in Water Analysis

    The people responsible for conducting oil in water measurements understand that the measurement can be quite challenging. Wastewater from different sources can contain many different types of hydrocarbons, each with different chemical make-ups. On top of the lack of chemical uniformity in different oils, there has been a ...

  • Laboratory investigation into rock fracturing with expansive cement

    Expansive cement is powdery material which produces expansive stresses during chemical reaction. This paper examines possible breakage of hard rock under confining loads using expansive cement. Laboratory tests are conducted to assess the maximum expansive pressure produced by expansive cement. This is then used on norite rock samples under load-free and uniaxial loading conditions, to examine ...

  • Oil Analysis for Hydraulic Systems

    Hydraulic systems are used in industrial, mobile and aviation applications to transmit power to operate equipment. They are incredibly efficient, compact, and lightweight relative to a mechanical equivalent. Hydraulic fluids transmit force in the system, and as such are carefully chosen by the system maker. Chemical stability, high flash and fire points, viscosity, and oxidation resistance are ...

  • Hazardous chemicals and proper storage solutions

    Many acceptable categorical storage schemes have been proposed and used by laboratories in academic, industrial, government and medical institutions. The common features uniting all these plans is the separation of incompatible materials. The differences in these various storage schemes arises in the number of groups that should be established for segregation purposes. The ten most commonly cited ...

  • Laboratory study on precipitation of strontium sulphate in Malaysia sandstone cores

    Scale formation is one of the most serious oil field problems that inflict water injection systems primarily when two incompatible waters are involved. Two waters are incompatible if they interact chemically and precipitate minerals mixed. Due to the lack of reaction kinetics data, the rate of strontium sulphate deposition in porous rock was measured through flooding sandstone core samples of ...

  • Simple laboratory techniques improve the operation of RO pre-treatment systems

    Membrane failures are often caused by poor pre-treatment design and/or poor operation. Systems are frequently designed and built without a clear understanding of the chemistry of the feed water to be treated and the physical characteristics of the particulate matter it contains. The larger the system the more likely is some incident of pre-treatment failure, often at a high financial cost to the ...
