  • APSI mode simplifies MS spectral analysis

    Analysis of gaseous species by quadrupole mass spectrometry involves ionisation of the molecular species most typically by the electron bombardment technique, the ionisation process creating fragmentation ions additionally to the parent ion. Spectral interpretation can then be compromised by spectral interference in some gaseous mixtures. Hiden Analytical introduce the APSI(Appearance Potential ...

  • Airport De-Icing Operations and Waste Water - Case Study

    De-icing of aircrafts and airfield pavement is important to ensure the safety of passengers and cargo operators. These operations can have negative environmental impacts, due to the presence of ethylene glycol and propylene glycol, which contribute to high levels of BOD in surface water.  Regulations are in place to ensure that waste from de-icing operations are properly collected and ...

  • Model-based methodology for the design of optimal control strategies in MBR plants

    This paper proposes a model-based methodology that allows synthesising the most appropriate strategies for optimising the operation of wastewater treatment plants (WWTPs). The methodology is applied with the aim of maximising the nitrogen removal in membrane bioreactors (MBRs). The proposed procedure is based on a systematic approach composed of four steps. First, a sensitivity analysis of the ...

  • Efficient removal of Cd2+ ion from water by calcium alginate hydrogel filtration membrane

    Calcium alginate (CaAlg) hydrogel filtration membrane was prepared using urea as pore-forming agent. The effects of preparation and operating conditions on the removal rate of Cd2+ were researched. The removal mechanism of Cd2+ and the anti-fouling property of CaAlg membrane were investigated. The removal rate of the CaAlg filtration membrane reached over 99.5% within 120 min when 20 ...

  • How FSMA Impacts Food and Beverage Manufacturers

    The food and beverage industry have evolved significantly over the past 10 years. The rules for the FDA’s Food Safety Modernization Act (FSMA) have changed food and beverage manufacturing by having companies focus on preventing their products from being contaminated rather than limiting the scope of contaminations. “FSMA is the largest overhaul of government regulations since the ...

  • Automating drainage direction and physiographic inputs to the CEQUEAU hydrological model: sensitivity testing on the lower Saint John River watershed, Canada

    CEQUEAU is a process-based hydrological model capable of simulating river flows and temperatures. Despite an active user base, no facility yet exists for the automatic assembly and input of watershed data required for flow simulations. CEQUEAU can therefore be time-consuming to implement, particularly on large (≥104 km2) watersheds. We detail a new MATLAB toolbox designed to remove this ...

  • Chemical adsorption of oxytetracycline from aqueous solution by modified molecular sieves

    The removal of oxytetracycline (OTC) from aqueous solution on modified molecular sieve via adsorption was investigated in the present work. The copper(II) modified molecular sieve had the much higher adsorbed amount than unmodified one. The bigger pore, the more adsorption sites benefitted for the adsorbed amount of OTC. The exchanged amount of copper(II) and the acid-base property of solution ...
