Together, two water treatment plants in Boulder, CO, have the capacity to treat 55 million gallons per day (MGD). When severe drought conditions restricted the source water supply of the Betasso WTP, the city decided to expand the capacity of the Boulder Reservoir Water Treatment Plant (WTP).
For many years, Huber Heights, OH, searched for an effective and affordable way to eliminate gaseous chlorine (Cl2) use at its 4.46 MGD Needmore Road Water Treatment Plant. An innovative dry calcium hypochlorite makeup and delivery system now provides a safer disinfection method for operators and the community.
Water is disinfected before it enters the distribution system to ensure that dangerous microbial contaminants are killed.
In an effort to reduce reliance on dwindling surface and groundwater supplies in Texas, the Colorado River Municipal Water District (CRMWD) constructed a new Raw Water Production Facility (RWPF) in Big Spring. Big Spring is a 27,000-member community located in West Texas approximately 300 miles west of Dallas. This RWPF treats secondary wastewater to a standard that allows it to be re-introduced directly into the raw water supply for the water treatment plants of Big Spring, Odessa, and other communities in the region.
Water professionals are seeking innovative approaches to address water supply challenges associated with population growth, drought, and environmental protection.
The TrojanUVPhox™ installation at Tucson's Advanced Oxidation Process Water Treatment Facility treats 1,4-dioxane and produces water that is blended and then treated at the neighboring Tucson Airport Remediation Project facility. This purified water is supplied to nearly 50,000 end users.
When the Cobb County-Marietta Water Authority (CCMWA) anticipated the need to upgrade the Hugh A. Wyckoff water treatment plant, they turned to granular activated carbon (GAC) technology after vetting several alternatives. The plant, a wholesaler in a two-plant system, processes up to 72 million gallons per day and serves about 350,000 people. Comprising of Wyckoff and the James E. Quarles treatment plant, CCMWA is the second largest water provider in Georgia.
Remember when “Little Old Lady” Clara Peller rolled up to the drive-through window of Big Bun and asked “Where’s the beef?” She was asking a literal question, but also making a figurative statement.
The NeoTech Aqua ReFleX™ water purification chambers are the most efficient and compact units available today. They require an order of magnitude less energy and less than 25% of the system volume to achieve the same or better purification result as competing chambers. This is the first in a series of three white papers explaining the benefits of these systems. By J. R. Cooper, Ph.D, NeoTech Aqua Solutions, Inc.
In 2005, in response to changes to the Canadian Drinking Water Quality guidelines, the Greater Vancouver Water District Board approved a proposal to upgrade the Coquitlam WTP with UV disinfection technology to act as the primary means of disinfection.
A water utility in the Midwest USA uses Monochloramine treatment in their two surface water treatment plants to disinfect raw water and establish residual disinfectant prior to discharge to their distribution system.
For Robert Stout, general manager of Mid-Arkansas Utilities (MAU), the primary water provider for a three-county rural area spanning 2,220 square miles, the reason to switch to a dry calcium hypochlorite feeding system was simple, “using chlorine gas was not only dangerous for us, it was a big hassle and time-consuming.”
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.
Lonza Microbial Control produces the new generation Constant Chlor® Plus calcium hypochlorite briquette feed systems that provide increased capacity and accuracy that exceeds its first generation system, plus new capabilities and features that further enhance operation, maintenance and safety.
Calgon Carbon Corporation (NYSE:CCC), and its European operation Chemviron Carbon, is a global manufacturer and supplier of granular activated carbon, innovative treatment systems, value added technologies and services for optimizing production processes and safely purifying the environment
JCS Industries, Inc. was founded in 2002 as a product development company charged with developing an alternative to the current vacuum feed liquid doser technology for a worldwide manufacturer of water and waste treatment equipment. After one year of design and two years of beta testing, JCS developed the Model 4100 Automatic Vacuum Liquid Feeder.
3M Liqui-Cel Membrane Contactors are used for degassing liquids. They are most commonly used for O2 removal from water and CO2 removal from water, but they are also capable of controlling a variety of other dissolved gasses as well, such as Nitrogen.

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.
