Asahi Kasei Chemicals Corp. |
Microza™ selected for largest-scale waterworks in the US
|
|
The Microza™ hollow-fiber membrane filtration system has
been selected for a new waterworks facility to serve the metropolitan area of
Minneapolis, Minnesota, with full-capacity operation scheduled to begin in January
2011. Located in Fridley, the plant will have a water treatment capacity of 360
thousand m3/day. This will make it one of the largest drinking water
plants in the US, and among the largest plants anywhere to utilize a pressurized
membrane filtration system for water purification. Selection was concluded after
extensive testing and evaluation by the Minneapolis Water Works, confirming the
outstanding performance of the Microza™ system.
Membrane filtration offers many advantages over conventional water treatment by
sedimentation and sand filtration, notably the ability to efficiently and reliably
achieve high rates of removal of pathogenic microorganisms such as cryptosporidium.
With stringent regulations for removal of cryptosporidium from drinking water
supplies scheduled to come into effect in the US, the adoption of large-scale
membrane filtration systems for water treatment is projected to grow substantially.
Since 1997, Microza™ systems have been adopted at over two hundred waterworks
plants in the US, including those currently under construction.
While membrane filtration has generally been considered most suitable for
smaller-scale installations, the excellent scalability of Microza™ systems has
enabled their successful adoption at many large facilities.
Asahi Kasei Chemicals will continue to pursue orders for the largest-scale
water-treatment systems, which make the most of the Microza™ membrane's high
mechanical strength and chemical resistance for stable production of high-quality water.
