  • A quick guide to oil analysis for engine test applications

    Reliability testing is a very important component of new engine development. Engineers need to fully understand and chart the engine lifetime performance under a variety of conditions before mass production may be considered. Many important performance data parameters are collected in real time through the many different types of sensors that are connected to the engine in the test cell and oil ...

  • Jar Testing for Metals Removal

    Using the chart below, find the metal(s) of concern. Determine the best pH range for maximum insolubility for the metal(s). If there is a combination of metals, then concentrate on the metal with the highest concentration and adjust the pH to this point. Determining the Optimum pH for combined metals: Typically facilities have 2, 3 or more different metals in their waste stream. To determine the ...

  • Data Centre CRAC unit efficiency improvements

    One of the main types of project Munters look at is energy efficiency improvements within the thermal management side. One of the easiest changes that can be made is swapping out the old AC powered motors for EC powered impellors. the reductions in energy is considerable, with some older belt drive unit changes measuring a saving of over 60% this is due to the design of the new impellors and the ...

  • Pilot testing of a membrane bioreactor for metals removal

    The City of Davis, California (City) Water Pollution Control Plant (WPCP) is facing stricter effluent permit requirements and compliance with the California Toxics Rule (CTR) effluent limitations. The impact of these requirements will necessitate upgrades to the existing WPCP to include conventional secondary and tertiary processes to control the discharge of biochemical oxygen demand (BOD), ...

  • Mining application - Heavy metals testing in water

    Isaac Plains is an open cut coal mine, in Northern Queensland, Australia. The Isaac Plains Project operates under an Environmental Authority (EA). They needed a field test for heavy metals compliance. The water sources included  potable water, mine affected water, natural creek flows, water releases, groundwater and the receiving environment. The site water management system is comprised of ...

  • Heavy Metals Water Testing Powered by DNA

    Water pollution is a worldwide problem affecting developing and developed countries alike. Heavy metal contaminants are one prevalent type of water pollutant. They are persistent in the environment once d is charged and removal from source waters is necessary to ensure a clean drinking water supply. The problem of heavy metal pollution arises from several sources. Heavy metals such as uranium can ...

  • Metal Polishing

    Integrated Engineers, Inc. conducted a treatability test for a facility that polishes stainless steel. We were asked to assist them in meeting their local discharge requirements as the flocculant they had been using was not working sufficiently. The initial pH of the wastewater upon arrival was 7.0. 3.0 grams of Floccin-G was used per 1000 ml jar of wastewater. After mixing for 10 minutes, the ...

  • Pilot test of pollution control and metal resource recovery for acid mine drainage

    The study was undertaken in order to recover the metal resources from acid mine drainage (AMD). A 300 m3/d continuous system was designed and fractional precipitation technology employed for the main metals Fe, Cu, Zn, and Mn recovery. The system was operated for six months using actual AMD in situ. The chemicals' input and also the retention time was optimized. Furthermore, the ...

  • Evaluation of Metals, Metalloids, and Ash Mixture Toxicity Using Sediment Toxicity Testing

    In December 2008, a release of 4.1 million m3 of coal ash from the Tennessee Valley Authority Kingston Fossil plant occurred. Ash washed into the Emory River and migrated downstream into the Clinch and Tennessee Rivers. A Baseline Ecological Risk Assessment evaluated risks to ecological receptors from ash in the river system post‐dredging. This paper describes the approach used and results ...

  • Mining Metals Solution Treatability

    Integrated Engineers, Inc. conducted a treatability test on water containing metals in solution from a mining company’s analysis labs. Initial pH was below 2, so it was adjusted to 6.5 to 7.5 using caustic. This lowers the solubility of the metals, and helps the Floccin to work better. The Floccin-1105 worked well at a dosage of 2.1 grams/ 1,000 ml of wastewater (treatment dosage of .9 lbs. of ...

  • Scrap Metal Recycling 1

    Integrated Engineers provided treatability services for the facility for three areas onsite: the oil water separator, tin baler effluent water, and aluminum shavings/cutting oil runoff. The facility processes and bales scrap metal for recycling. The three different waters were treated with Floccin J. Oil Separator The oil separator water is used to remove any free oil that is floating on top of ...

  • Sintered Metal Manufacturing 2

    This facility generates 2 waste streams from their metal sintering operations. This second waste stream comes from their post conditioning of the parts with the use of detergents for cleaning and a polishing compound for surface finish/deburring. The wastewater stored in several tanks and is hauled off site for disposal at $0.62/gallon. The treatability with Floccin H is shown in the jar test ...

  • Sintered Metal Manufacturing 1

    This facility generates 2 waste streams from their metal sintering operations. The first waste stream comes from their cutting oil operations and rinse water. The wastewater is then stored in several tanks and allowed to partially separate with some of the floating oil skimmed off. The residual wastewater (3,000 gallons/week) is then hauled off site for disposal at $1.15/gallon. The treatability ...

  • Heavy Metals Analysis

    Correct measurement results are a prerequisite for compliance with limit values, which are always specified as total metals. Heavy metals such as copper, nickel, zinc, etc. can be quickly and reliably determined in aqueous samples with the help of the LANGE cuvette tests. Matrix factors (e.g. interference ions, colour, turbidities, etc.) may have a negative impact on themeasurement and cause ...
