Solving the Problem of Water Quality and Demand

  1. 1. GE Power & Water Solving The Problem of Water Quality and Demand
  2. 2. 2 • Municipalities continue to evolve, creating an environment that is ripe with challenges yet equally rich with opportunities • An escalating crisis worldwide is water scarcity. For municipalities, this issue is exacerbated by new housing developments which require water treatment plants to meet the needs of larger populations and diverse geographies • Environmental policies are becoming more stringent—and influential. New nutrient limits on discharge of wastewater require action and compliance from municipalities Municipal Waste Water Problem
  3. 3. 3 Power Industry Water Shortage • It is estimated that the global demand for electricity will double in the next 20 years. Since large amounts of water is required to produce electricity, demand for water will triple in the same time frame • World’s water resources are limited, this can pose significant limitations on potential industry growth and profitability • Facilities face stringent regulations related to water and solid waste discharge, CO2 reductions, selenium, mercury and heavy metal removal, and air quality
  4. 4. 4 GE Technology & Solutions With ever increasing regulatory, environmental and financial pressures on today’s municipalities and the power industry, GE provides innovations in chemical and equipment technology to enhance municipalities’ efficiency and excellence in wastewater treatment and reuse, and drinking water treatment while safeguarding natural resources and saving money
  5. 5. 5 Solutions for Municipal Waste Water ZeeWeed membrane bioreactor (MBR) systems combine proven ultrafiltration (UF) technology with biological treatment for municipal wastewater treatment and water reuse, resulting in consistent, high quality effluent suitable for any discharge or reuse application. ZeeWeed ultrafiltration (UF) systems are proven to consistently outperform conventional filtration technology while meeting or exceeding regulatory requirements, regardless of source water quality. Electrodialysis reversal (EDR) products are ideal to desalinate challenging brackish waters such as surface water and wastewater. Applications for EDR technology include municipal drinking water and wastewater treatment and reuse projects. Reverse osmosis systems deliver high performance water purification at the lowest life-cycle costs. The pre-engineered systems are built with high-quality components such as GE’s spiral-wound membranes—cost-effective thin-film elements used to remove salts and separate organic material by molecular weight or particle charge.

Solutions for the Power Industry
  7. 7. 7 ZeeWeed® Membrane Technology • ZeeWeed® Ultrafiltration (UF) membrane is a pressure-driven barrier to suspended solids, bacteria, viruses, endotoxins and other pathogens used to produce water with very high purity and low silt density • It can serve as a treatment for surface water, ground water, and biologically treated municipal effluent (membrane bioreactor and tertiary treatment) • It can also serve as a pre-treatment before reverse osmosis and other membrane systems The global installed base of GE's ZeeWeed® ultrafiltration (UF) membrane has the capacity to enable the reuse of over 425 million gallons of water per day for a variety of uses, equivalent to the daily water consumption of 4.7 million average Americans
  8. 8. 8 Membrane Bioreactor (MBR) – The Process • The ZeeWeed membrane bioreactor (MBR) process is a GE technology that consists of a suspended growth biological reactor integrated with an ultrafiltration membrane system, using the ZeeWeed hollow fiber membrane • ZeeWeed ultrafiltration membranes are immersed in an aeration tank, in direct contact with mixed liquor. Through the use of a permeate pump, a vacuum is applied to a header connected to the membranes • The vacuum draws the treated water through the hollow fiber ultrafiltration membranes. Permeate is then directed to disinfection or discharge facilities • Intermittent airflow is introduced to the bottom of the membrane module, producing turbulence that scours the external surface of the hollow fibers. This scouring action transfers rejected solids away from the membrane surface
  9. 9. 9 Membrane Bioreactor - Features and Benefits Physical ultrafiltration (UF) barrier • Produces a high quality effluent suitable for direct reuse Unmatched fiber ruggedness • Ensures a longer membrane life in harsh wastewater operating environments Hollow fiber geometry • Provides a greater filtration surface area which reduces plant footprint and effectively distributes cleaning solutions Effective backpulse cleaning • Maintains long-term, peak system performance and provides a simple, rapid method of recovery in the event of a plant upset Automated in-situ cleaning • Simplifies system operation and maintenance, while reducing operating costs "Self-healing" fibers • No catastrophic membrane failures means that your plant keeps working Compact design • Smaller plant footprint reduces capital costs Proven system performance • Successful track record of operation in hundreds of municipal and industrial applications provides you with peace of mind
