How One Plant Found Great Service Through Turbidity Analyzers
10/3/2016
The nearly 16,000 people in Calhoun, GA, rely on two drinking water treatment facilities — one that pulls its water from a river and another that pulls from groundwater — that process about 9 MGD. The turbidity of the river’s water can fluctuate dramatically, so the operators rely on the surface water treatment plant’s turbidity analyzers to ensure that they are serving the population as they should.

Case Study: Newport News Uses Emerson Ozone Instrumentation For Safe, Effective Disinfection
5/22/2006
Maintaining the quality of the water supply is the top priority for municipal drinking water treatment plants across the country. Water plants use several treatment processes to ensure water quality and safety, and these treatment steps include disinfection. Traditionally, chlorine is used in both primary and secondary disinfection treatments and has been used since 1908. Some water plants are moving to ozone for primary disinfection. One water utility that is taking this direction is Newport News Waterworks.

Chlorine Measurement In Wastewater And Regulated Discharge Requirements
8/8/2014
Homes, industry, schools, and businesses all generate sanitary waste, or sewage. Sewage treatment is a multistage process that cleans up wastewater before discharge or reuse. In the final step of the treatment, disinfectants are added to kill disease-causing organisms. Common disinfectants are chlorine gas and sodium hypochlorite. Chlorine dosage levels are designed to leave almost no residual in the wastewater after treatment

Application Datasheet: Desalination Of Sea Water
10/16/2006
Areas with large, growing populations and little fresh water resources are increasingly turning to desalination for their water needs. Many industrial plants and electrical utilities are located by the ocean so that they can be assured of a large, dependable, fixed-cost water supply. Seawater, however, is so corrosive that it is generally more cost effective to remove the salt than to replace piping or install pipe of more resistant materials.

Smart Wireless Technology Solves Environmental Monitoring Challenge
10/31/2013
Faced with the challenge of meeting environmental monitoring legislation, Korsnäs Gävle needed a way to monitor water from their heat exchangers for contamination before discharging it to the sea. Additionally, the board and paper manufacturer required new sensors for continuous monitoring of pH, dissolved oxygen, and water temperatures from effluent emissions in their basins and ponds. In this case study, learn how Korsnäs Gävle implemented a wireless sensor network to quickly achieve compliance and meet its monitoring needs.
