GE's ZeeWeed technology in place at the Nanaimo treatment plant.
The city’s previous system was a single form of treatment involving coarse and fine screening of water to remove large debris followed by chlorine injection. The new system using GE technology is a multibarrier approach to safe drinking water with a fine-screening, two-stage siphon membrane system and chlorine disinfection. The first membrane stage consists of seven trains of ZeeWeed 1000 modules. The second stage, consisting of four trains of ZeeWeed 500d membranes followed by ultraviolet disinfection, treats the backwash water from the first stage to increase overall plant recovery to more than 99 percent. The plant is capable of treating up to 116 million liters per day (30 million gallons).
The South Fork of the Nanaimo River watershed covers 230 square kilometers -- an area three times larger than the city. Its two storage lakes, Jump Lake and South Fork Lake, collect water, rain and snowmelt flowing from the mountains. Raw water quality can be severely impacted by weather events such as heavy rainfall or rapid snow melt, and GE’s ZeeWeed membranes enable the city to meet the drinking water quality criteria while reducing chemical and power consumption and minimizing the production of waste from the facility.
“Stricter regulations and the desire of municipalities to produce safe and reliable drinking water are driving more creative and innovative water treatment solutions. GE’s ZeeWeed technology for the Nanaimo plant is a change from the city’s previous water treatment approach to a membrane-based water treatment facility. This multibarrier approach will filter out contaminants and bacteria for a safer water supply,” said Kevin Cassidy, global leader, engineered systems -- water and process technologies for GE Power.
GE's ZeeWeed technology is an advanced filtration technology that separates particles, bacteria and viruses from water or wastewater. Nearly 1,000 plants worldwide use this technology to produce superior quality water. Its unique ability to handle high large volumes of water in a small footprint, combined with the highly efficient process with low energy and low chemical usage, makes it ideal for treating raw water sources and producing drinking quality water for cities and populated areas.
