  • Effect of iodine chemical form on thyroid doses during a severe accident

    In most of the accidents that may occur in nuclear reactors, the short-term radiological consequences are expected to be dominated by isotopes of iodine. The assessment of doses resulting from iodine release during a severe reactor accident requires knowledge of the iodine chemical forms and removal mechanisms prior to the release to the environment. In this paper, the arguments concerning iodine ...

  • Mono nov dosing pumps offer the right mix for foundry systems

    Integrated Sand Systems Ltd of Walsall carried out extensive trials over a 12 month period before deciding to replace gear and diaphragm pumps, previously incorporated in its Temcon catalyst control system, with Mono progressing cavity pumps. The Temcon system is built into the company’s high speed continuous sand mixers, which blend sand with chemicals and resins, setting hard to form a mould ...

  • Chemically enhancing primary clarifiers: model-based development of a dosing controller and full-scale implementation

    Chemically enhanced primary treatment (CEPT) can be used to mitigate the adverse effect of wet weather flow on wastewater treatment processes. In particular, it can reduce the particulate pollution load to subsequent secondary unit processes, such as biofiltration, which may suffer from clogging by an overload of particulate matter. In this paper, a simple primary clarifier model able to take ...

  • Excessive sulfuric acid dosing resulting in irreversible scale formation

    Many consultants in the RO water treatment industry recommend sulfuric acid dosing into the feed water as a safety measure. This case study reviews a situation where acid dosing was used with the intention of improving system performance but resulted in severe sulfate scaling. The difficulties in cleaning sulfate scales are discussed and after numerous lengthy trials, an effective cleaning ...

  • Advancements in Scaling Calculations and an in depth look at Antiscalant dosing for stressed waters and high recovery systems

    Abstract Over the past few decades the Reverse Osmosis (RO) industry has observed an increase in applications in challenging waters. Water sources that were never considered suitable for RO are now commonplace, including municipal waste streams, industrial waste, and even mining waste. Furthermore, regulatory restrictions, environmental obligations, solid waste expenses, and water supply ...
