  • Saving Silicon Valley How A Reuse Project Became Its Own Tech Breakthrough
    facility uses a trio of tertiary treatment technologies to add a local safe reliable resource to Silicon Valley s supply portfolio Transforming Water Water reuse requires not only motivation and technology but also a market that values the product An earlier study revealed that salinity was a concern in the existing recycled supply for a region where consistent quality was crucial in industrial user operations A feasibility study confirmed that development of an advanced recycled water treatment facility with a high quality water product that could be blended with existing recycled water would provide more consistent recycled water quality Evaluation of options ensued and approximately 5 5 million in state grants from the California Department of Water Resources and 8 25 million in federal funding through the American Recovery and Reinvestment Act helped fund the resulting 72 million project The state of the art SVAWPC purifies nitrified secondary effluent from the neighboring San Jose Santa Clara Regional Wastewater Facility using an integrated membrane system consisting of 38 million liters day ML d or 10 MGD microfiltration MF and 30 3 ML d 8 MGD reverse osmosis RO followed by a 38 ML d 10 MGD UV disinfection process The purified water is then blended with existing recycled water produced at the regional facility to enhance quality and expand reuse The backwash from the MF units and neutralized products from the MF and RO chemical cleaning are returned to the regional facility for treatment The brine from the RO system is returned to the regional facility s chlorine contract basin for blending with the plant s effluent prior to the discharge into San Francisco Bay Using advanced treatment processes to further remove pollutants and other potentially harmful constituents such as salt from the recycled water opens up additional potential uses for the recycled water The higher quality recycled water could be used in the future to improve groundwater quality which would further reduce the demand on potable water supplies The new water supply is distributed via the regional purple pipe recycled water system More than 700 SBWR customers now use the enhanced recycled water With total dissolved solids levels of approximately 500 mg L the blended water reduces chemical use and maintenance costs for industrial users and is easier to use in some irrigation and agricultural applications because of reduced salt buildup Demonstrated Success A 30 day performance acceptance test demonstrated that equipment could operate continuously for 24 hours a day under design conditions with no major interruptions and still meet permitted water quality requirements The test also demonstrated successful integration of the product water into the existing recycled water system under various operating modes Black Veatch served as the prime consultant for the project providing design membrane procurement and construction and operations support JR Filanc served as the general construction contractor The SVAWPC began operations in March 2014 followed by a grand opening ceremony in July In addition to increasing recycled water treatment capacity and quality for the region and

  • Arsenic Update Top Technologies Revealed
    of use has been iron removal There are a number of communities particularly in the Midwest that have high iron in their water Many of these communities for many years were not removing the iron Utilities would get red water complaints but they didn t remove it because of the cost involved The arsenic regulation pushed them into removing the iron so now they solve two problems The third most popular technology is probably coagulation filtration where you add iron coagulant to the water and it precipitates into iron particles adsorbs the arsenic and gets filtered out In terms of compliance when the regulation came out in the early 2000s the EPA estimated that about 5 000 water utilities would be noncompliant and that the vast majority of those would be small systems The issue now after 10 years and with about 800 to 1 000 communities still out of compliance is not so much treatment technology but funding They re struggling to find the funds to install the technology and to support the operation and maintenance of the technologies What is cost prohibitive about arsenic treatment Adsorptive media typically has a limited capacity and when it can no longer remove arsenic the common practice is to pull out the media and replace it with new media The life of the media is dependent on many factors including water quality Some water utilities have had to replace their media after just three or four months of operation others can wait four or five years Replacing the media is rather expensive generally about 80 percent of the operational cost but I ve always been convinced that some media could be regenerated It would be similar to having a water softener which takes off calcium and magnesium and replaces it with sodium when it reaches its capacity you regenerate it with salt Early on many of the adsorptive media manufacturers indicated that the iron based media couldn t be regenerated but here at EPA we always thought that it could So we collected exhausted media from a number of small water utilities brought it back to the lab and looked at regenerating the material What we did was increase the pH which strips off the arsenic It doesn t impact its physical properties or have any other detrimental effects on the media You can put it back in place and it will have nearly its original adsorption capability Because media replacement is the largest operational expense we felt that regeneration could reduce costs substantially Is media regeneration practiced at full scale and to what effect After we essentially proved that it can be done in the lab and through pilot studies we looked for a water utility that was interested in trying the process at full scale We found one in California at Twentynine Palms They had two tanks of media Both tanks were exhausted and the utility was accustomed to paying approximately 20 000 on replacement media In our discussions with
