Problem: The city of White Rock, British Columbia, faced elevated arsenic and manganese in its drinking water sourced from the Sunnyside Uplands Aquifer. This prompted the city to build a water treatment plant with funding from the Clean Water and Wastewater Fund.
Solution: The White Rock Water Treatment Plant uses a multi-stage process to remove arsenic and manganese. The treatment includes pre-oxidation with ozone followed by manganese removal using Greensand Plus media filters and arsenic removal using Bayoxide E33 media filters. The ozone pre-oxidation enhances filtration and adsorption, improving the overall water quality. A key component of the plant is technology from Mazzei that mixes ozone into the raw water using sidestream injector skids and pipeline flash reactors. The system minimizes the facility footprint and limits the use of construction materials and chemicals.
Result: The process significantly improved water quality, increased storage capacity by 33%, and completed secondary disinfection. The use of ozone saves energy, reduces maintenance, and enhances safety for employees and residents. 661-363-6500; www.mazzei.net
