Water from Well 19 and 20 in Sacramento, California area was high in manganese and arsenic. Due to the high levels, the wells were not being used to supply municipal water to the District. Each facility is planned to initially produce and treat approximately 600 gpm with a future expansion capacity to 1200 gpm.
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.
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
In 2000, Indiana American Water, a subsidiary of American Water Company, purchased the Warsaw Indiana system which serves a population of over 16,000. Indiana American then completed a Comprehensive Planning Study that included a number of upgrades and improvements to enhance the reliability, safety and water quality of the system.
When water demand declines, water quality and utility budgets can suffer. When the situation arose in Akron, OH, a smart solution emerged.
Rangely is a remote town with a population of just over 2,200 people located in the upper northwest area of Colorado, thirteen miles from the Utah border. During the course of their routine maintenance, operators noticed problems with a distribution pump. Read the full project profile to learn how Process Solutions’ trained service technicians were able to walk them through a series of diagnostics to further isolate the problem and get the system was back up and running in a short period of time.
A Nebraska reservoir was experiencing toxic algae in its water. Constructed by the U.S. Army Corps of Engineers (COE) primarily as a flood control reservoir with recreation and irrigation as secondary uses, the reservoir has a surface area of 700+ acres with an average depth of almost 12 feet.
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.
Drinking water treatment plants use various forms of chlorine to inactivate pathogens, oxidize metals or metalloids and provide disinfection residual for distribution systems. By Glen Smith, PEPCON Systems
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.
The financial cost to maintain their ozone equipment, and increasing scarcity of replacement parts for their ozone generator, motivated a utility in Springfield, MO, to upgrade their ozone system. Read the full case study to learn how the plant assessed the energy cost of a sidestream ozone injection system compared to that of a turbine mixing design and showed that the Mazzei retrofit design reduced the energy cost of ozone contacting by an average of 69.2% under all plant flow conditions.
Sometimes technology innovations come along which cause a paradigm shift in how products are designed.
A San Jose Water Quality Engineer said, "I wasn’t convinced that PSI’s Monoclor chloramine dosing system would solve our problems after several failed attempts to improve residual, but with PSI offering a trial including installation, operation, and troubleshooting for three months, San Jose Water decided to invest the necessary resources to pilot this system.
A chemical company which specializes in Clean-In-Place (CIP) systems, contacted Mazzei to discuss the use of ozone as an alternative to peracetic acid sanitation or heat sterilization at their customers’ plants.
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.
With a history of scientific innovation, MIOX Corporation began manufacturing on-site generators in 1994. Now with more than 1,700 installations in hundreds of U.S. communities and over 30 countries, MIOX is employed in many markets and applications including potable water, wastewater and reuse, commercial swimming pools, on board military and cruise ships, cooling towers, the beverage industry, oil and gas water treatment, and other commercial and industrial applications.

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.
