  • "Real World" test results of Sialex device in industrial boiler

    Laboratory is a useful step, but many times operations managers / maintenance engineers ask "Can it work in my operation?" A Sialex Ring appears a simple uncomplicated device yet it is designed to remove already existing as well as combat further "Scale" build-up in water bearing pipes and devices attached to these pipes. This includes boilers. "Hard" water (containing high concentrations of Ca / ...

  • Are Fines Reducing Your Hydrocarbon Production?

    Although choosing frac sand can reduce completions design cost initially, there can be short-term and long-term issues: Proppant flowback, proppant embedment, and decreased fracture conductivity, in addition to fines, can negatively affect hydrocarbon production. What are fines? Fines are generated by crushing of proppant, by erosion of sand on the fracture face during treatment, ...

  • Guide To Coolant In Oil Test Methods

    Liquid cooled engines and rotating equipment use glycol based coolants because of their excellent heat transfer abilities. However, glycol based coolants are not desirable at all in lubrication oil itself – Coolant ingression to the lubricant is a particularly nasty contaminant for the variety of damage it can cause. Glycol coolants break down in the high temperature engine environment, ...

  • Enhancing capacitive deionization technology as an effective method for water treatment using commercially available graphene

    In recent years, capacitive deionization (CDI) has been reported as one of the emerging technologies developed with the purpose of water desalination. This work is aimed at the integration of supercapacitor electrodes for efficient removal of ions from water, and thus to achieve an energy efficient, and cost-effective water treatment process. Our objective is to transfer the vast knowledge of ...

  • Environmental fate and behavior of acesulfame in laboratory experiments

    Acesulfame is a widely used artificial sweetener. It can be discharged into surface water by domestic wastewater due to its incomplete retention during wastewater treatment. Concentrations may reach up to 10 μg/L for smaller rivers. State-of-the-art analysis allows the determination of acesulfame traces (0.01 μg/L) and thus a potential tracking of the presence of wastewater in riverbank ...

  • Influence of nutrient supplementation on DOC removal in drinking water biofilters

    Analysis of the impacts of nitrogen, phosphorus and potassium supplementation on biofilter performance for organic carbon removal was studied on laboratory-scale biofilter columns. Three dual media biofilter columns were fed with synthetic raw water C:N:P ratios of 546:24:1, 100:10:1, and 25:5:1 (w/w) to simulate nutrient limited and two nutrient supplemented conditions, respectively. Research ...

  • Rapid start-up of one-stage deammonification MBBR without addition of external inoculum

    In recent years, the anammox process has emerged as a useful method for robust and efficient nitrogen removal in wastewater treatment plants (WWTPs). This paper evaluates a one-stage deammonification (nitritation and anammox) start-up using carrier material without using anammox inoculum. A continuous laboratory-scale process was followed by full-scale operation with reject water from the ...

  • Assessment of inlet efficiency through a 3D simulation: numerical and experimental comparison

    Inlet efficiency is a requirement for characterizing the flow transfers between surface and sewer flow during rain events. The dual drainage approach is based on the joint analysis of both upper and lower drainage levels, and the flow transfer is one of the relevant elements to define properly this joint behaviour. This paper presents the results of an experimental and numerical investigation ...
