GE Expands its Capabilities to Meet Global Water Challenges, Introducing the ZeeWeed* 1500 Pressurized Membrane System

TREVOSE, PA.—March 16, 2009— Building on more than 20 years of experience with ultrafiltration (UF) membrane technology, GE Water, a business unit of GE Energy, is expanding its family of ZeeWeed UF products with the introduction of the ZeeWeed 1500.

The new pressurized ZeeWeed 1500 module offers cost-effective, skid-mounted solutions that can be rapidly installed for water treatment, tertiary filtration and pretreatment for brackish and seawater desalination. It is available for small- and medium-sized packaged and custom designs for municipal and industrial plants and joins GE’s growing portfolio of products designed to tackle global water challenges.

“The evolution of the ZeeWeed 1500 leverages decades of UF membrane experience earned at some of the world’s most demanding water and wastewater applications,” said Heiner Markhoff, president and CEO, GE Water. “The addition of a new pressurized membrane expands the versatility of our portfolio and provides our clients with a broader choice of robust, cost-effective products to help achieve their treatment needs.”

Key features of the ZeeWeed 1500 include:

  • Low-fouling PVDF membrane chemistry offering lower frequency and less aggressive cleaning;
  • Outside-in filtration process providing uniform flow distribution and solids loading with no blocked fibers;
  • Ultrafiltration barrier to produce high quality effluent that meets the toughest treatment requirements;
  • Lower chemical usage over comparable systems ;
  • Compact module and simple rack design, with on-rack inspection capability;
  • Ability to retrofit other outside-in UF and MF systems.

Clean energy and
water all-in-one
Today, more than one billion people around the world lack access
to safe water sources. To address this issue, GE researchers are
engaged in a project with Texas Tech University, a world-recognized
research center for wind-water integration and application,
to develop affordable water desalination systems that increase the
quantity and quality of clean water available in arid areas around
the United States and globally. The partnership focuses on the
integration of renewable-energy systems, such as wind turbines,
with membrane desalination processes. The development of
the integrated renewable energy-water system has the potential
to significantly reduce the cost of creating new sources of fresh
water from impaired resources, such as brackish water, by directly
addressing the major component of operating cost of desalination
systems — energy.

Arabidopsis thaliana

Arabidopsis thaliana

Arabidopsis thaliana (A-ra-bi-dóp-sis tha-li-á-na; thale cress, mouse-ear cress or Arabidopsis), is a small flowering plant native to Europe, Asia, and northwestern Africa.[1] A spring annual with a relatively short life cycle, Arabidopsis is popular as a model organism in plant biology and genetics. Its genome is one of the smallest plant genomes and was the first plant genome to be sequenced. Arabidopsis is a popular tool for understanding the molecular biology of many plant traits, including flower development and light sensing.

Plastic producing plants

Plastic-Producing Plants: The cash crop of the future

November, 2000: Stanford, California

From water bottles to artificial heart valves, plastics are essential to our everyday lives. Plastics are synthetic resins made of large, organic polymers refined from valuable natural fossil fuels (oil, coal, petroleum, or natural gas). Normally, plastics take years to degrade and are a major component of landfill and waste areas. However, Dr. Chris Somerville, director of the Carnegie Institute of Washington’s Department of Plant Biology, and other institute scientists have discovered a method for engineering plants to make plastic that would biodegrade more easily–and not use up natural resources in the production process.

Futures in Biotech 39: Food, Genetically Modified

Hosts: Marc Pelletier

Dr. Lisa Weasel discusses the controversies surrounding genetically-modified foods.

Guest: Dr. Lisa Weasel, associate professor of biology at Portland State University in Oregon, a member of Governor Ted Kulongoski's task force on developing public policy for bio-pharmaceutical crops in Oregon, and author of Food Fray: Inside the Controversy over Genetically Modified Foods.

Why isn't there a wide consumer acceptance of genetically modified (GM) foods? If we can design crops that reduce pesticides, grow more effectively in poor soil, bring nutrients such as vitamins A to populations with high incidences of blindness, or even just taste better, why are we hesitating?
