애리조나 물 협회는 남부 애리조나 산타 크루즈 밸리(Santa Cruz Valley)에 위치한 Ak-Chin 인디언 보호구역의 표면 수처리 플랜트에 2013 연간 최고 물 프로젝트 상을 수여하였다. 위 수처리 플랜트는 GE 사의 개선된 ZeeWeed 500 정화 기술을 채택하고 있다.

2012년 설계된 이 새로운 플랜트는 피날 카운티(Pinal County) 남서부 지역, 피닉스(Phoenix)로부터 50 마일 북쪽에 떨어진 곳에 세워졌고 이 지역 최초의 표면 수처리 시설인 것으로 알려졌다. 본 시설은 마리코파-스탠필드(Maricopa-Stanfield) 수로 시스템과 센트럴 애리조나 프로젝트 수로 시스테믈 통해 표면수 할당량을 공급받는다.

 

이를 통해 해당 지역은 안정적인 물 공급을 보장받고 미래 경제 성장을 위한 적정한 계획을 세울 수 있게 되었다. 추가적으로, 본 플랜트는 하루 225만 갤런을 처리하는 성능을 자랑하며 하라스(Harrahs) Ak-Chin 카지노와 지역 주민들에게 음용수를 공급하는 역할을 한다.

TREVOSE, PA, July 19, 2013 -- The AZ Water Association recently honored a surface water treatment plant in the Ak-Chin Indian Community, located in the Santa Cruz Valley of Southern Arizona, with the 2013 Water Project of the Year Award while using GE's (NYSE: GE) ZeeWeed* 500 advanced filtration technology.

The new plant, commissioned in 2012, is the first surface water treatment utility for the community, located 50 miles south of Phoenix in the northwestern part of Pinal County. The facility receives its surface water allotment of Colorado River Water supplied via the Maricopa-Stanfield canal system and the Central Arizona Project canal; this gives it a secure source of water, allowing for the population to properly plan for future growth and expansion. Additionally, the plant has a capacity of 2.25 million gallons per day and provides drinking water to community members and Harrahs Ak-Chin Casino.

GE also provided the technology for the Ak-Chin Indian Community's nearby membrane bioreactor water reclamation facility, which provides Arizona Class A+ effluent for water reuse and recharge, and also won an international and multiple state awards. Carollo Engineers in Phoenix is responsible for the award-winning design of both plants. Further, this project represents the latest successful partnering effort between GE and Carollo Engineers in Arizona.

GE ZeeWeed 500 technology is an advanced filtration technology that separates particles, bacteria and viruses from water or wastewater. It can handle high peaks of solids and turbidity, combined with the high-efficient process and low energy and chemicals usage, making it ideal for treating deteriorated or high-variation raw water sources and producing high and stable drinking quality water.

Ultrafiltration uses a semipermeable membrane barrier to reject suspended solids, bacteria, viruses, endotoxins and other pathogens in water to produce treated water known as permeate with very high purity and low silt density. It serves as a pretreatment for surface water, seawater and biologically treated municipal effluent before reverse osmosis and other membrane water treatment systems. Ultrafiltration also is used in industry to separate suspended solids from solution. GEs ZeeWeed ultrafiltration membranes offer an unmatched combination of ultrafiltration performance, energy efficiency, durability, fast installation, ease of operation and reliability.
