When dissolved carbon dioxide in the water began overloading the anion resin and decreasing capacity at its Rokeby Generating Station, Lincoln Electric Systems had to act quickly to update its winter contingency plans and meet increasing demand. In this case study, learn why the municipality chose a membrane degasifying system over chemical treatment options or a forced draft aerator, thus reducing costs and improving overall efficiency by minimizing downtime.
Filtration systems for manufacturing often require high-purity filters to remove contaminants from water, liquids or gases, as well as to optimize production and meet quality standards. By Robert LeConche, President of Shelco Filters
Nutrient removal from wastewater is an increasingly common requirement for water resource recovery facilities (WRRF). Nitrogen and phosphorus are the nutrients being targeted.
Accurately measuring flow is critical for water utility operations. Also, regulatory agencies mandate flow monitoring and require annual calibration of meters. But even a meter in perfect condition and properly calibrated can read inaccurately. Flow disturbances are a common cause of accuracy and repeatability errors.
Located on the Pacific Ring of Fire, the Philippines experience frequent earthquakes, volcanic eruptions, and typhoons that cause catastrophic losses. Manila Water Company, Inc., prepared a Natural Calamity Risk Resiliency and Mitigation Masterplan to ensure that there is a reliable water supply in the event of a natural disaster for the service area covering the East Zone of Metro Manila (the National Capital Region) and Rizal Province.

In today’s economic climate, it’s tempting to want to buy the cheapest test equipment you can now. But, how can you tell what the true cost of test equipment is? You have to consider how widely your water and chemical consumption will vary as the readings on your instrumentation does. By Heather Rekalske, Myron L Company
Most people accept that major purchases in life — e.g., housing, automobiles, appliances — come with cyclical budgeting impacts that require amortizing costs over the long term, through savings or borrowing. Why should anyone expect the national water infrastructure to be any different?
Averting regulatory violations and fines. Avoiding system disruptions. Maintaining effective monitoring in complex applications. How do you tackle these kinds of age-old plant monitoring problems?
