Over the course of many years the City of Celina, Ohio has been challenged with supplying drinking water to the 11,647 residents of the city and the East Jefferson District.
Sometimes technology innovations come along which cause a paradigm shift in how products are designed.
In chloramination, continuous online monitoring and increased frequency of measurements allow you to react faster to changes in water quality. The Bachman WTP in Dallas, TX tested the new Hach 5500sc Ammonia Monochloramine Analyzer against other lab and process analyzers. Read the full case study to see how the increased frequency of the 5500sc AMC measurements allow the Bachman Plant to react faster to water quality changes and further optimize their chloramination processes. Dr. Vadim B. Malkov, Product Applications Manager
The City of Palm Coast, FL was experiencing elevated color in the concentrate stream being directed to the lime softening facility to recover as drinking water. In an effort to meet secondary color standards at the lime plant, this water quality issue limited the volume of the concentrate able to be recovered.
The global market for water treatment technologies is growing and becoming increasingly important as the quality and quantity of freshwater sources are stressed and the link between fresh water sources and wastewater — returned to the environment — is more and more obvious. By Rick VanSant, President & CEO, UV Pure Technologies, Inc.
While chlorination has long dominated water disinfection, new approaches and technologies have emerged in the wake of disinfection byproduct (DBP) regulations. Could peracetic acid (PAA) be the option that dethrones the king?
When the government of Baja California, Mexico, declared a water emergency for the region of San Quintín in 2014, leaders knew they needed to find a solution to ensure residents a reliable, safe water source.
The wastewater treatment facility of the remote mountain resort community of Pinecrest Lake bears the brunt of spring runoff and increased summer demands in the area's beautiful surroundings.
The White Tanks Regional Water Treatment Facility (White Tanks) is located in Surprise, Arizona, and treats surface water from the Colorado River that is delivered by a 336 mile (540 kilometer) man-made canal.
The North Columbus Resource Facility recently completed a $12-million replacement of its settled water filtration, removing the existing Wheeler filters, their three-part media and 10-inch poured concrete underdrains, which were no longer efficient.
The user population of a Central Texas resort system does not reach its peak until summer and the resultant levels of peak and low usage vary widely. This fluctuation impacts levels of disinfectant residual and, consequently, water quality — especially at the end of the line. Manual flushing of the utility's hydrants to maintain water quality has resulted in excessive time and labor as workers must access the outlying areas.
New York City is home to more than 8 million people, making it the most populous city in the United States. The majority of New York's drinking water is supplied by the Catskill/Delaware watershed, located approximately 100 miles outside the city. Historically, NYC has not filtered the water from this system, nor did they require any additional barriers to microbial contaminants due to the pristine nature of the watershed.
Monitoring chlorine and fluoride levels in the drinking water of Utah’s Taylorsville-Bennion Improvement District used to be expensive, labor intensive, and often sensitive to interference from the variable frequency drives used to operate the chlorine injection pumps. That is, until the district upgraded to Rosemount Analytical free chlorine and fluoride sensors and analyzers from Emerson Process Management.
From utility water to wastewater, whether used in industrial processes or for drinking, disinfection plays a prominent role in providing safe and useable water. Water free from pathogens and other microorganisms ensures processes run efficiently and people are kept safe from disease. By Harland R Pond, Business Development Manager – Water Treatment

UV Pure Systems are self-cleaning, and smart - with multiple sensors and on-board diagnostics. They are engineered to be fail-safe and virtually maintenance-free. Lamps are mounted in air surrounded by elliptical reflectors providing more effective deactivation of pathogens, incorporating easy lamp changes and visual quartz inspection. Remote monitoring is available.
Water disinfection is the process of removing unwanted chemicals, biological contaminants, suspended solids and gases from contaminated water. It is also the elimination, deactivation or killing of pathogenic microorganisms.
Methods used include physical processes such as filtration, sedimentation, and distillation, biological processes such as slow sand filters or activated sludge, chemical processes such as flocculation and chlorination and the use of electromagnetic radiation such as ultraviolet light.
Ozonators produce small quantities of ozone which is a strong oxidizing agent that kills pathogens over a short period of time.
