  • Boiler feed water -power generation facility application case studies

    Challenge A large power generation client required a treatment solution to meet the parameters required for their boiler feed operations. The inlet feed water contained several contaminants including hardness minerals such as calcium/magnesium, dissolved salts, trace hydrocarbon and certain heavy metals including ferric iron. Solution Genesis Water ...

  • Influence of feed quality on seawater reverse osmosis performance

    The trouble-free operation of a Reverse Osmosis (RO) plant relies on the quality of the treated feed water, which highlights the need for optimisation of the pre-treatment steps. The quality of raw seawater varies with time in terms of suspended and colloidal load, along with the dissolved salt content. In a conventional pre-treatment scheme, consisting of clarification and particulate and micron ...

  • Aminoglycoside Antibiotics in Feed Apramycin, Gentamicin, Neomycin

    Aminoglycoside antibiotics are among those commonly used in animal feeds to manage intestinal microorganisms. The beneficial effects include improved growth and generally healthier animal populations. Use of antibiotics creates a demand for analytical procedures to verify concentrations in pre-mixes and feeds and in some instances for residue analysis in animal products. This note describes a ...

  • Improved Anaerobic Digestion Feed Systems and Concepts

    The sludge feed systems for anaerobic digestion facilities at wastewater plants in North America have been and continue to be modified and upgraded for a variety of reasons. These reasons include operational problems and issues, evolution from prior primary-sludge-only digestion facilities, performance-based reasons, regulatory-based reasons, and include the desire to improve the digestion ...

  • Improvement of multi-parameter-based feed-forward coagulant dosing control systems with feed-back functionalities

    Coagulant dosing control in drinking and wastewater treatment plants (WWTPs) is often limited to flow proportional concepts. The advanced multi-parameter-based dosing control systems have significantly reduced coagulant consumption and improved outlet qualities. Due to the long retention time in separation stages, these models are mostly based on feed-forward (FF) models. This paper ...

  • Linking feeding inhibition with reproductive impairment in Gammarus confirms the ecological relevance of feeding assays in environmental monitoring

    The in situ feeding bioassay in Gammarus fossarum is recognised as a reliable tool for monitoring the toxicity of freshwater contamination. However, whether recorded feeding inhibitions can potentially provoke population‐level adverse outcomes remains an open question. Here we present an experimental study in G. fossarum, which contributes to the quantitative description of the links between ...

  • Fuzzy-logic-based identification of transients in the feed-water system of a nuclear power plant

    This paper addresses the problem of the on-line identification of transients in monitored process signals. A fuzzy-logic-based methodology is adopted. A case study is considered regarding the identification of transients in one section of the feed-water system of a nuclear power plant. The noise associated with the (simulated) signals renders the task of trend identification rather difficult. In ...
