  • Republic Steel: CapDI for Cooling Towers - Case Study

    Introduction & process description Water is often a hidden cost of industrial sites and can contribute significantly to operational costs. Cooling towers are used to reject heat through the natural process of evaporation providing cooled water across a broad range of applications. Due to evaporative losses, the water remaining in the cooling tower becomes concentrated with dissolved ...

  • Enhancement of struvite pellets crystallization in a full-scale plant using an industrial grade magnesium product

    A full-scale struvite crystallization system was operated for the treatment of the centrate obtained from the sludge anaerobic digester in a municipal wastewater treatment plant. Additionally, the feasibility of an industrial grade Mg(OH)2 as a cheap magnesium and alkali source was also investigated. The struvite crystallization plant was operated for two different periods: period I, in which ...

  • 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 ...

  • 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 ...
