Arizona tissue mill saves with GE ZeeWeed MBR

Doubletree Paper Mills in Gila Bend, AZ, says it is saving 300,000 gallons of water daily by using GE’s ZeeWeed membrane bioreactor (MBR) technology. The mill has been able to double its production capacity without affecting the limited treatment capacity of the small desert city’s existing municipal wastewater treatment plant.

Situated some 70 miles southwest of Phoenix, Doubletree is GE’s first MBR wastewater re-use project for a US paper mill. Privately-owned Doubletree makes high-quality paper and tissue products for retailers in the southwest.

GE says the ZeeWeed ultrafiltration (UF) hollow-fiber membranes are designed for a robust life expectancy and reduced site footprint. They are used for drinking water, wastewater, tertiary and water reuse applications, as well as industrial feedwater and reverse osmosis (RO) pre-treatment. The advanced technology is already operational in thousands of municipal, industrial, and commercial applications worldwide.

The mill says the system requires minimal maintenance and is continuously monitored by GE.
