  • E-Z Trays selected for Large scale project - Case Study

    A former industrial plant and top Superfund site in Sydney, Australia, had been in operation since the 1930s and contained chlorinated solvent contamination. Because of the size and scope of this project packed towers traditionally would have been the air stripping method of choice, but the client was concerned about the ability of workers having easy access to maintain and clean the units. They ...

  • Flora Digital prints with Renishaw`s optical encoders - Case Study

    Background What is the maximum resolution of the human eye? There are a number of factors that influence this including viewing distance, lighting conditions and eye health. In general a healthy human eye has a maximum resolution of 350 DPI or 73 µm (1 arc min) at the normal reading distance (250 mm). Irrespective of future breakthroughs in printing technology, there ...

  • REVO-2 and the ATOM encoder - Case Study

    The REVO multi-sensor system is one of Renishaw's flagship products and enables CMM users to perform 5-axis measurement on a 3-axis co-ordinate measuring machine (CMM). It measures 1000s of points/sec and operates at speeds up to 500 mm/s. As the head is much lighter and more dynamic than the CMM, it is able to quickly follow changes in the part geometry without introducing harmful ...

  • Removal and recovery of N, P and K from urine via ammonia stripping and precipitations of struvite and struvite-K

    This study investigated the recovery of N, P and K from source-separated urine in laboratory-scale combined processes of air stripping and precipitation. Two operation scenarios were carried out to recover N/P (named partial scenario) and N/P/K (named complete scenario). Most of the nutrients were recovered (>70%) by optimising the operation parameters including the increase of air flow ...

  • Impact of Corrosion on Electronic Equipment

    Corrosion is the destruction of metals through reaction with compounds in their environment. It is a natural process because compounds such as oxides, sulphides and chlorides are formed and these are stabler than pure metals. Electronic circuits and components are omnipresent in our environment. Until recently, the thousands of soldered joints that an electronic circuit contains were ...

  • Case Study - Estonian Cell - BCTMP Mill

    Wastewater generated at Estonian Cell The Aspen pulp mill Estonian Cell, part of Heinzel Group, rewarded HydroThane the contract as the technology supplier for their anaerobic treatment after having done extensive piloting in 2011. Since January 2014 the anaerobic treatment has been in operation, earning AS Estonian Cell both national and international recognition as being ...

  • Ammonia removal from landfill leachate by struvite formation: an alarming concentration of phosphorus in the treated effluent

    This study examined the removal of ammonia nitrogen from the leachate of a landfill site using the chemical precipitation of struvite (MgNH4PO4.6H2O). This procedure achieved a reduction in the ammonia concentration that was higher than 99% when the molar ratio of 1.8:1.0:1.4 for Mg2+:NH4+:PO43− was adopted. The ...

  • Global Analysis of Truncated RNA Ends Reveals New Insights into Ribosome Stalling in Plants

    High-throughput approaches for profiling the 5′ ends of RNA degradation intermediates on a genome-wide scale are frequently applied to analyze and validate cleavage sites guided by microRNAs (miRNAs). However, the complexity of the RNA degradome other than miRNA targets is currently largely uncharacterized, and this limits the application of RNA degradome studies. We conducted a global ...

  • Nitrous oxide emissions from one-step partial nitritation/anammox processes

    Measurements of nitrous oxide were made at pilot- and full-scale plants to evaluate greenhouse gas emissions from one-step partial nitritation/anammox processes applied in moving bed biofilm reactors treating reject water. It was found that 0.51–1.29% and 0.35–1.33% of the total nitrogen loads in the pilot- and full-scale reactor, respectively, were emitted as nitrous oxide. Between 80 and 90% ...

  • Alkaline fermentation of waste activated sludge stimulated by saponin: volatile fatty acid production, mechanisms and pilot-scale application

    Volatile fatty acid (VFA) production stimulated by saponin (SP), an environmentally friendly bio-surfactant, was investigated during sludge alkaline fermentation in laboratory studies and pilot applications. The combined use of SP and pH 9 condition significantly enhanced VFA production to approximately 425 mg COD/g VSS, which was 4.7-fold of raw sludge and 1.5-fold of sole pH 10 adjustment ...
