  • Reverse Osmosis

    The United States Pharmacopeial Convention Inc. (USP) has proposed new specifications for Water for Injection (WFI) and Purified Water (PW). These specifications will include quantitative conductivity, and total organic carbon (TOC) measurements will replace 100-year-old qualitative wet chemistry tests. The impetus behind these changes is to create a means of analysis that is less ...

  • Least-Cost Approaches to Reducing Acid Emissions

    ' The costs of meeting sulfur emission targets can be high. It is essential, therefore, that countries adopt policies which (a) minimize the net economic and social costs of reducing emissions to the agreed target levels, and (b) maximize the overlap between measures designed to reduce acidifying emissions and those addressing other forms of air pollution. This note discusses alternative ...

  • Real-time TOC tightens effluent control at Greencore

    A food manufacturing facility in Selby has installed a new continuous TOC (Total Organic Carbon) monitor, ‘the BioTector’ which has dramatically improved the site’s capability to refine and improve the plant’s wastewater treatment process. As a result the plant is better able to quickly respond to changes in the influent. Greencore Foods is a leading player in the food ...


  • Remote monitors track river restoration success

    The Norfolk Rivers Trust has installed a remote river monitoring station that has been tracking water quality and flow before and after river restoration work at an area of ecological importance on the River Nar. Rising in chalk hills to the east of the village of Tittleshall, the river flows south for 2.5 km until it reaches Mileham, then predominately west for 39.5 km through the villages of ...
