No matter how sophisticated a fluid analyzer system may be, it will be ineffective if a sample flow fails to reach the analyzer sensor or if the sample is contaminated or stale.
Over the course of a 1.5-month field experiment at a Canadian starch mill biological wastewater treatment process, LuminUltra Technologies demonstrated the benefits of using 2nd Generation ATP® monitoring technology. ATP (Adenosine Triphosphate) monitoring technology is an accurate biomass measurement that can rapidly monitor all types of biological wastewater treatment processes, aerobic and anaerobic alike.
Back in 2012, the City Of Columbia made the decision to update its OPS SQL software to Hach WIMS (water information management system). The old software was not only sitting idle, but was also out of date. The reasons for updating and implementing the software were many but can be summarized with the two primary goals: To collect the data into a central database that is easily accessible and to create a dashboard from which the rotating operations teams or management could quickly understand what was happening. After more than a year of coordinating Metro management and staff, Hach WIMS support staff, and city IT staff, WIMS began to take shape.
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.
Suspended growth systems, such as activated sludge, are a very common form of secondary wastewater treatment. The potential to optimize and improve the operation of such treatment plants using ATP is tremendous. ATP can directly quantify active biomass, which is key to providing secondary treatment. Two of the many potential uses for ATP in a wastewater treatment plant are aeration and solids optimization and toxicity monitoring and identification.
Misinformation about WirelessHART networks prevails among many instrument engineers in the process industries. This article attempts to set the record straight by debunking seven myths about these networks.
Vallviks Bruk AB, located about 200 km (125 miles) north of Stockholm, produces softwood kraft pulp and chemical pulp for export. Some years ago, increased environmental requirements led to a major investment in a biological treatment plant. Read the full case study to learn why ABB instrumentation was an obvious choice when the Swedish pulp producer Vallviks Bruk AB built a new plant for biological water treatment.
The city staff of Buckhannon, West Virginia, recently ran into a situation that didn’t add up. A flow meter at one of the city’s booster stations was indicating a flow rate higher than the capacity of the station’s pumps. The staff contacted the applications team at McCrometer about its flow meter accuracy problem.
A food processing company in northern California has a small wastewater treatment plant to treat its wastewater before releasing it back to the local municipality.
