A Comparative Study Of On-Line And Laboratory TOC Analyzers For Analysis Of Municipal Wastewater
This application note presents comparative data obtained on influent and effluent wastewater samples using laboratory and on-line TOC analyzers employing the heated sodium persulfate oxidation technique in USEPA-approved methods 415.3 and SM 5310C.
Mapping And Identifying The Source Of Water Quality Issues
A Southern U.S. municipality experiencing taste and odor issues in a certain neighborhood was also having difficulty maintaining chlorine residual levels in the area. Biological growth was suspected, however, water leaving the treatment plant met and exceeded all water quality requirements. After several investigations, the source of contamination in the distribution system could still not be identified.
Active Energy Control – Energy Reductions Of Up To 10% Above Standard Drives
Energy costs continue to increase. At the same time, there is increased pressure to reduce utility bills without sacrificing operations or comfort.
Application Note: Small Team Saves Big Hassles With The Professional Plus Multiparameter Instrument
In the past, Shinkle and her colleagues carried separate YSI meters
for pH and DO, she notes. Now they use the YSI Professional Plus
handheld multiparameter instrument, which allows them to measure
pH, DO and temperature with one quick, reliable instrument. By YSI
