Evaluation of approaches for consumers to eliminate chlorine off-flavors from drinking water at point-of-use
Chlorine off-flavors of tap water have caused dissatisfaction and distrust from some consumers, placing pressure on operators concerning water disinfection. Evaluating practical approaches for eliminating chlorinous off-flavors by consumers at point-of-use while avoiding production of toxic byproducts is a practical concern. Three recognized dechlorination methods: ultraviolet (UV) irradiation, ...

Treatment of arsenic-contaminated water using in-line electrolysis, co-precipitation and filtration in Costa Rica
A novel treatment was tested with groundwater to investigate its arsenic removal under natural conditions. The system utilised in-line electrochlorination to oxidise water constituents without the need for external chemical supply. The oxidised arsenic and iron co-precipitated and were filtered via Greensand Plus™. The filter was catalytically active and provided an emergency oxidant. The ...

Effects of phosphorus on biofilm disinfections in model drinking water distribution systems
Drinking water biofilm development is affected by the available nutrient levels and the presence of disinfectants. Phosphorus is recognized as another important limiting nutrient besides organic carbon. In this study, drinking water biofilms were developed in annular reactors to examine the effects of phosphorus on the biofilm disinfections with free chlorine and monochloramine. Phosphorus ...

KDF 55 Process Medium Helps with Chlorine Removal in a Municipal Water Treatment Facility - Case Study
A Los Angeles-based maker of fashion jeans uses KDF media instead of chemicals for removing chlorine when treating municipal water in their stone-washing process. High-purity copper-zinc redox water filter media consistently provides 99% of free chlorine removal from water by electrochemically reducing dissolved chlorine gas to water-soluble chloride ions. (More information on how KDF® ...

UV Technologies for Chlorine Removal from Water
Chlorine is widely used in water treatment as a disinfection and oxidizing agent. However, the reaction of free chlorine in water leads to the generation of undesirable by-products and have harmful effects on industrial processes. In high purity water systems, the presence of free chlorine in water may result in the deterioration of treatment units such as ion exchange beds and RO membranes. ...

Ultraviolet Light Oxidation of Free-Chlorine in Water
Chlorine is the most frequently used chemical for water disinfection. Many industrial and commercial manufacturing facilities cannot tolerate the introduction of chlorine into the process because of contamination and unwanted chemical reactions. Chlorine affects the flavour and odour of drinks and fluids, accelerates corrosion on process vessels and piping, and can also damage delicate process ...

The Use Of UV For Dechlorination
For many years chemical disinfection techniques have been used to provide microbiologically pure water for industrial and domestic use. Free chlorine, typically introduced by municipal water treatment plants in gaseous form, has been employed for many decades as a primary oxidising agent for the control of microbiological growth. Free chlorine can also be introduced through the injection of ...
