New DOW IntegraFlo Ultrafiltration Modules Reduce Overall System Costs And Increase Plant Efficiency

Enhanced, ultra-efficient design helps deliver up to 85 percent more flow compared to traditional modules potentially resulting in reduced capital expenditures by up to 25 percent*

Today at Aquatech China 2013, Dow Water & Process Solutions (DW&PS), a business unit of The Dow Chemical Company (NYSE:DOW), launched its latest ultrafiltration (UF) innovation with a new efficient module design that is intended to provide high-quality water while reducing overall system costs.

New DOW IntegraFlo ultrafiltration modules have an enhanced design that that is expected to deliver up to 85 percent more flow* compared to conventional UF modules, and requires less piping and skid infrastructure to reduce UF system capital expenditure by up to 25 percent.* Available in two sizes, IntegraFlo modules offer design flexibility to suit a wide range of applications including industrial, municipal, sea-water desalination pretreatment and waste water reuse.

The ultra-efficient module design has 85 percent more active membrane area than competitive modules* to facilitate higher productivity without an increase in module size or weight. Due to the larger membrane area, fewer modules are required, thus reducing the footprint of the installation by up to 45 percent.*

“We are excited to provide the industry with a solution that enables plant design to be elevated to the next level of ultrafiltration productivity,” said Rajat Mehta, global product director for Dow Water & Process Solutions.  “Dow’s proven, low-fouling, PVDF, outside-in ultrafiltration technology combined with a new, efficient module design can help boost plant efficiency for our customers.”

Systems designed with DOW Ultrafiltration technology use an outside-in flow configuration, which allows for less plugging, higher solids loading, higher flow area and easy cleaning. In addition, such configuration enables the use of air-scour, which boosts cleaning efficiency. Dow’s advanced asymmetric H-PVDF hollow fiber membrane is formed from high-grade polymeric chemicals, PVDF, which offers the best combination of mechanical properties and resistance to chemicals. Its uniform pore size and high pore density enables optimum flow distribution and high permeability. The use of the DOW Ultrafiltration membrane ensures that a perfect barrier is created without sacrificing performance.

“The new DOW IntegraFlo ultrafiltration modules are intended to help our customers in China meet the growing challenges for clean and affordable water supply,” said Christina Fang, greater China commercial director for Dow Water & Process Solutions.
