PROPAK

RePAK

What GE offersGE offers the broadest portfolio of water and process technologies, including: separation equipment; membrane and filtration

technology; monitoring solutions; analytical instruments; specialty chemicals; mobile water capabilities; service; and financing. We

focus on difficult-to-treat water and wastewater, and implementing water reuse solutions to provide customers with the quantity

and quality of water they need for their applications.

The PROPAK and RePAK systems combine GE’s vast technical experience in ultrafiltration (UF) and reverse osmosis (RO) into an

integrated UF and RO platform. Each system has its unique purpose: the PROPAK provides high quality water from high variability

surface water and the RePAK provides tertiary wastewater reuse.

ZeeWeed* 1500 UF—experienced evolutionVersatile and reliable, the pressurized ZeeWeed 1500 module is ideally

suited for use in numerous applications, including water treatment, tertiary

filtration and pretreatment for brackish and seawater desalination.

ZeeWeed 1500 is ideal for pretreatment for RO systems.

PROPAK and RePAK BenefitsBy integrating the core UF and RO technologies as one solution, our customers realize many benefits including:

• Clear operator access for maintenance. Designed to allow operators clear access to

membranes, cartridge filters, pumps, valves and sensors for easy

scheduled maintenance.

• 35% reduction of footprint. The integrated UF/RO

systemwithasingletankforCIP,back-pulseand

break provides a 35% smaller footprint compared to

using traditional UF, RO and tank skids.

• 10% reduction in installation costs. Your cost to

install the PROPAK or RePAK is reduced compared to

traditional UF and RO systems because of a reduction

in interconnecting piping, pre-engineered skid footprints and

connection points, and a pre-integrated control package.

• GE spiral wound membranes.Withover40yearsexperienceinmakingflatsheetmembrane

modules, GE manufactures membranes with an average rejection of 99.0% to 99.5% of salts for high quality

product water. While RePAK uses GE PRO RO membranes, RePAK uses GE’s low fouling membranes to handle

the more turbid feedwater conditions.

• One integrated control system. With a full suite of monitoring capabilities, the Central PLC control offers

full monitoring instrumentation and Ethernet connectivity.

• Patented depth filters for superior membrane protection. GE filters’ pure polypropylene

construction ensures consistent results, trapping particles throughout its depth.

• Multi-stage pump for reliable operation. PROPAK features

theASSeriesTonkaflo*pump,whichisamulti-stage

centrifugal pump with an all stainless steel liquid end

mounted on a high thrust bearing frame for superior

performance. RePAK features Grundfos pumps to meet

the required pressure of wastewater treatment.

• UF integrity test. Clear PVC tubing at each ZeeWeed

1500 module allows for visual verification of the

automated integrity test and discrete identification of

specific fiber breakage within a module via a bubble test.

• ZeeWeed 1500 UF modules. Low-fouling PVDF membrane

chemistry requiring less frequent and less aggressive cleaning,
