Decrease Membrane Treatment Capital And O&M Costs With Optimum Flux Rates
6/30/2014
Despite a global effort to standardize units of measure to the metric system, the water treatment industry still follows the U.S. trend in resisting that directive by referring to water volumes in treatment plants as gallons per day (GPD). While achieving a specified permeate GPD is certainly important in overall membrane plant design, production capacity has absolutely nothing to do with determining optimal methods of treating site-specific feedwaters and offers no indication of potential membrane fouling rates and related maintenance costs. To evaluate these factors, knowledgeable professionals rely on membrane flux rates as the key consideration in achieving optimal system design and operation. By Harold G. Fravel Jr., Executive Director, American Membrane Technology Association and Karen Lindsey, VP, Avista Technologies, Inc.

Has Fracking Gone ‘Green’?
6/6/2014
There are few topics more controversial these days than hydraulic fracturing ("fracking"). While the debate rages on as to whether fracking poses a risk to water quality, a new desalination technique addresses two other environmental concerns: water scarcity and greenhouse gas (GHG) emissions. Developed by researchers at the University of British Columbia (UBC), the breakthrough technology uses excess carbon dioxide created in the fracking process to desalinate the process water, making it available for water reuse. It also generates chemicals — hydrochloric acid and carbonate salts — that are valuable for many industrial applications.

Understanding The Critical Relationship Between Reverse Osmosis Recovery Rates And Concentration Factors
4/28/2014
Every aspect of a reverse osmosis (RO) membrane operation requires some degree of process math. Changes in operating conditions that may be considered minor can actually have significant and detrimental effects on system performance. This is certainly the case when calculating system recovery rates, and the subsequent changes in concentration factors, in RO plant operation.

Can Co-Locating Utilities Solve The Water-Energy Nexus?
4/21/2014
Resources being a scarce commodity, it’s incumbent upon us to optimize the use of water and energy as best we can. While conservation is the prime course of action for the public, the best solution for utilities may be to work smarter — by having the water-energy nexus work for us instead of against us.

Waste Heat Recovery For Desalination From Steam Power Plants
4/17/2014
Currently, in the Kingdom of Saudi Arabia about 1.5 million barrels of oil are consumed daily to generate electricity to drive reverse osmosis desalination plants. This represents about 15 percent of KSA’s daily oil production.
