  • Power Plant Improves Operating Efficiency with Culligan Matrix Solutions

    Challenge A large chemical manufacture was challenged with boiler tube failures in its power plant, resulting in costly repairs and down time. The boiler tube failures were a result of the incoming water quality to the power plant. Until recently, the boiler make-up water was treated with a combination of carbon media filtration and softening. As a result less than 50% of condensate was ...

  • Factors Affecting Cyanide Generation in Chlorinated Wastewater Effluent Matrix

    ABSTRACTFalse positives for cyanide analysis in wastewaters have been reported. We examined the effects of storage time at high pH and of pH adjustments on the cyanide levels. Cyanide levels changed within the holding time allowed by Standard Methods. We also studied the difference in cyanide levels using two disinfection conditions -- breakpoint chlorination and chloramination. Glycine was used ...

  • Identifying drinking water and water treatment systems vulnerabilities using the CARVER matrix method

    Originally designed for target analysis, CARVER is an acronym for the vulnerability assessment elements of criticality, accessibility, recuperability, vulnerability, effect and recognisability. Every category is assessed for each component or subcomponent of a designated target. Scoring can be based on any scale but typically ranges from the lowest significance of 1, to the highest significance ...
