Generating Disinfectants From Water: Could In Situ Electrolytic Production Be The Future?

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

Drinking Water Disinfection: Tianjin, China (Case Study)
Favorable reviews of UV technology in wastewater applications influenced Tianjin Economic Development Area (TEDA) Water Supply General Company to investigate the potential of using UV for drinking water applications at one of its water treatment plants. With no previous UV installations for drinking water disinfection in the country, TEDA's process of selecting a UV manufacturer was stringent. We are honored that they chose us and our TrojanUVSwift™ system.
A Rosemount Chlorine Analyzer Proves Just The Job For Seawater Duty At Dow's Terneuzen Site
The Dow Benelux site in Terneuzen, the Netherlands, uses seawater for process cooling. Environmental regulations require careful control of the concentration of chlorine added to control microbial fouling. The existing chlorine measurement system had become outdated, so after stringent tests Dow decided to replace it with a Rosemount Analytical Model TCL analyzer from Emerson Process Management.

ORP Based Measurement Of Oxidizing Disinfectants In Aqueous Solutions
Oxidizing antimicrobials, such as chlorine, are common disinfectants used to treat water. Test strips, DPD kits, and colorimeters are currently the most popular methods for determining the relative disinfecting power of oxidizing antimicrobial agents in these applications. By Myron L Company
Veolia ACTIFLO Case Study: Somersworth, NH
The City of Somersworth has a historical background dating back to the early 1900s when it became the first community to start using chlorine to disinfect it’s drinking water. By Veolia Water Solutions & Technologies
Engineering For Safe Chlorine Disinfection
For more than 75 years chlorine has been effectively used to disinfect drinking water, eliminating dangerous bacteria and toxic compounds. Water supply engineers and treatment facility operators are used to necessary risks and problems associated with chlorine disinfection in order to deliver safe water. By Harland R. Pond, Product Manager; Grundfos
Drinking Water Disinfection - Coquitlam Water Treatment Plant, British Columbia (Case Study)
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.
On-Site Disinfection Helps Ensure Safety At British Columbia Water Treatment Facility
Constructed in 1997, the District of Chetwynd Water Treatment Plant (British Columbia, Canada) treats nearly 2,500 cubic meters of water per day using gas chlorination as its primary form of drinking water disinfection
No Wizardry In ‘Emerald City’s’ Dramatic Water Quality Improvement
With the installation of a new disinfection system featuring on-site sodium hypochlorite generation, a water treatment plant improved water quality and significantly reduced total trihalomethanes and haloacetic acid levels. By Ali Giti
Surface Water Treatment & LT2 Compliance - Surprise, Arizona (Case Study)
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.

Performance Of A Conventional Surface Water Plant Using Mixed-Oxidants For Microflocculation And Final Disinfection

The surface water source is from snow-melt and summer thunderstorm run-off from the mountains. This water is detained in McClure Reservoir (7876 ft elevation) and Nichols Reservoir (7483 ft elevation) upstream from the CRWTP, a conventional plant built in 1974 with a design capacity of 8 MGD. Because the City has limited surface water rights, and due to decreased demand, the treatment plant usually shuts down for 60 to 90 days during winter. The reservoirs thaw in spring and turn over in autumn, and during the summer rainy season, raw water turbidities may exceed 5 NTU. By MIOX Corporation
