Managed by the private, non-profit South Jasper Water Supply, Buna, Texas’ water system contains 91 miles of un-looped distribution pipe with historical water losses of up to 30%. A small operations team is responsible for monitoring two water plants, reading 700 meters, repairing leaks, and flushing water to control the water quality. In an effort to spend less time manually flushing hydrants and focus more time on repairing leaks to reduce non-revenue water loss, South Jasper Water Supply purchased and installed two (2) Hydro-Guard® HG-1 Basic/S Flushing Systems.

The city of Fort Lupton a growing Front Range community located along the South Platte River in Colorado, began operation of a new 5 MGD (18.93 MLD) membrane filtration system in 1997.
All chemical processes involve the loss, gain, or redistribution of electrons on an atom or group of atoms. Electricity is the movement of electrons along a conductor. It is no wonder then that chemical changes can be made to occur by passing an electric current through a solution containing atoms or groups of atoms which will accept or give up electrons. Processes which pass an electrical current through a solution to effect chemical changes are called electrochemical processes. By PEPCON Systems
The source water in Cudahy, a city just south of Milwaukee, is susceptible to contamination and significantly impacted by agricultural and urban runoff. After a Cryptosporidium outbreak in the early 1990s, improved water quality was vital. A UV solution proved to be the best fit for protection against the contaminant within a restrictive space.
Sometimes technology innovations come along which cause a paradigm shift in how products are designed.
The Evitts Creek Water Treatment Plant (WTP), owned and operated by the city of Cumberland, Maryland, provides potable water for Cumberland and surrounding communities in Maryland, West Virginia, and Pennsylvania.
Rapid detection of changes in water quality is critical in water delivery systems, wastewater treatment, and industrial plants for process optimization, environmental regulatory requirements, and consumer health.
Tampa Bay Water’s state-of-the-art surface water treatment plant has provided high-quality drinking water to the Tampa Bay region.
A combination of growing demand, aging infrastructure and regulatory requirements acted as drivers for a new ozone system at the Miramar Water Treatment Plant in San Diego, CA.
Eastern Municipal Water District (EMWD) serves about 142,000 customers in Riverside County, CA. The EMWD service area is one of the largest for any water district in arid southern California. On the drinking water side, EMWD manages two water treatment plants and over 15 reservoirs. With 70% of the district’s water coming from the Metropolitan Water District with chloramine disinfection, EMWD has become reliant on chloramine disinfection to manage long transmission lines and longer detention times.

UV Pure® Technologies develops and manufactures technically advanced UV water purification systems. Since 1998, over 12,000 UV Pure systems have been installed in residential, commercial, industrial, public and municipal applications treating wastewater, reuse water, rainwater, and drinking water. The company’s Crossfire Technology is dramatically advantaged compared to conventional ultraviolet systems. 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.
