Retrofit Significantly Reduces Backwash Cycle Interval, Duration And Water Use For Georgia Utility
Retrofit Significantly Reduces Backwash Cycle Interval, Duration And Water Use For Georgia Utility

The North Columbus Resource Facility recently completed a $12-million replacement of its settled water filtration, removing the existing Wheeler filters, their three-part media and 10-inch poured concrete underdrains, which were no longer efficient.

Taste and Odor Treatment with UV-Oxidation - Mississauga, Ontario (Case Study)
Taste and Odor Treatment with UV-Oxidation - Mississauga, Ontario (Case Study)

The Region of Peel is the second-largest Canadian municipality after the city of Toronto, and draws its drinking water from Lake Ontario — the smallest of the five Great Lakes. To meet the projected population increase from 1,160,000 people currently to an estimated 1,571,000 people in 2031, the Region decided to upgrade and expand its water treatment plant. To deal with seasonal taste and odor compounds produced by algae blooms in Lake Ontario, the membrane plant will be equipped with a Trojan UV-Oxidation system.

LA Story: Advanced Treatment, Reuse Saves Scarce Water Resources LA Story: Advanced Treatment, Reuse Saves Scarce Water Resources

Officials in Los Angeles have grown tired of importing water, which is an expensive, unsustainable response to the region's persistent drought. The smarter solution, they concluded, is to reuse local resources through advanced purification and aquifer recharge. But how do you ensure safety and efficiency before committing to a treatment technology? A unique piloting tool from Xylem’s Wedeco brand offered the city clear answers.

ABOUT DRINKING WATER DISINFECTION

WATER DISINFECTION

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.
