Alexandria, VA -- The Water Environment Federation (WEF) elected its 2005-2006 officers on Tuesday, November 1 in Washington, DC during a ceremony at WEFTEC 05, the Federation's 78th annual technical exhibition and conference.

J. Michael Read, Vice President of HDR Engineering, Inc. in Portland, Ore. was elected President; Mohamed Dahab, Professor and Chair of the Department of Civil Engineering at the University of Nebraska (Lincoln) became President-Elect; Adam Zabinski, First Deputy Commissioner of the Westchester County Department of Environmental Facilities from White Plains, New York, was elected Vice President; Lynn Orphan, watershed sector leader at Kennedy/Jenks Consultants in Reno, Nev., will serve as Immediate Past President; and Mike Godfrey, supervisor in Environmental Affairs for the Alabama Power Company from Birmingham, Ala., will complete a three-year term as Treasurer.

The officers were inducted during the Federation’s 64th annual Awards Celebration which recognizes the outstanding achievements of some of the most talented and dedicated professionals in water quality. The Federation presented over 25 awards and recognized Orphan for her outstanding contributions and service to WEF during the 2004-2005 year. Orphan then conducted the ceremonial "passing of the gavel" to Read who assumed the leadership of WEF for the 2005-2006 year.

WEFTEC.05 drew 18,132 water quality professionals from around the world to learn the latest practices, solutions, regulations, and emerging technologies in their field during the five-day event (October 29 through November 2). The conference featured 111 technical sessions, 25 workshops, 11 interactive facility tours and 876 exhibiting companies using over 214,000 square feet of floor space. WEFTEC®.06, the Federation’s 79th annual technical exhibition and conference will be held October 21-15, 2006 at the Dallas Convention Center in Dallas, Texas.

CCWD Receives Patent for New Water Treatment

Concord, CA -- The Contra Costa Water District (CCWD) has received a patent for a new approach to water treatment using chlorine dioxide in combination with ozone for disinfecting water.

“We are pleased that our patent application was approved. This will particularly help water districts that are dependent on the Delta for drinking water, to treat their water more effectively,” said General Manager Walter J. Bishop. He added that the discovery would remain in the public domain, and be available to all water utilities at no royalty costs.

The District filed for the patent on April 14, 2003, after leading a cooperative research project that found a significant benefit for bromate formation control from the new treatment process.

The study concluded that the combination of chlorine dioxide and ozone reduces the formation of bromate, a regulated disinfection by-product (DBP). It also reduces the total ozone dose needed, and modestly reduces energy demand and electricity consumption of the plant.

The purpose of the study was to evaluate the benefits of using chlorine dioxide as a pre-oxidant in combination with ozone for disinfecting water, in terms of potential DBP reduction and energy costs savings compared to other technologies. CCWD currently uses ozone as a primary disinfectant at its Bollman Water Treatment Plant in Concord, which serves 245,000 people in central Contra Costa County.

Ozone is considered a very effective disinfectant. However, when used on Delta water, which contains bromide (a constituent of sea water), ozone oxidizes bromide to become bromate. In California, 23 million people have the Delta as their drinking water source.

Control of DBPs in drinking water is becoming increasingly critical. Regulatory requirements are requiring higher levels of disinfection to control disease-causing microbes, while at the same time mandating lower levels of DBPs.

CCWD’s drinking water meets all state and federal standards, particularly those related to DBPs. However, with ever-stricter regulation, CCWD undertook the study, with funding from the American Water Works Association Research Foundation (AwwaRF) and the California Energy Commission (CEC), to find new ways to disinfect drinking water while minimizing production of bromate.

CCWD cooperated in this patent effort with AWWARF, CEC, and Black and Veatch, to assure that the potentially significant discovery would remain in the public domain, and available to all water utilities at no royalty costs.

Toronto, Canada -- The basis of almost all water softening systems is ion exchange equipment. Inside this equipment, a bed of organic material is used as the media for the softening process. Although the organic, bead-like resin is well suited for this process, it is an organic material much like carbon filters, and is therefore a breeding ground for bacteria and other microorganisms. This causes a problem because if bacteria and microorganisms are allowed to grow and multiply in such a setting, the softener media will lose its capacity to perform the ion exchange, as well as deliver the desired flow to the user.

Current Solutions:  In almost every case, the answer to this problem has been chlorine. Chlorine has the ability to disinfect the softener bed and has been the only viable solution to disinfecting softener beds. However, there are drawbacks to using chlorination as the disinfection method. First, the process of treating with chlorine is time consuming for the operator. Second, chlorination has been proven to breakdown the softening media, therefore limiting the capacity of the softening system to perform the exchange. Third, chlorine is a carcinogen and conventional wisdom would argue that reduction of chlorine in our drinking water is the way to go.

The Emerging Solution: UV Disinfection:  With the widespread acceptance of the Crossfire™ technology used in Hallett™ UV disinfection systems, the use of ultraviolet disinfection is now the emerging solution for disinfection of water softeners’ beds. In the past UV had not been an option, because conventional ultraviolet disinfection technology is unable to handle anything but “treated” water in order for the system to do its job properly.

Standard specifications on conventional systems require very tight operating parameters. Due to the pre-treatment variables found in both surface waters and ground waters, such as iron, manganese and hardness, it is virtually impossible to find a situation where the water prior to “treatment” is acceptable for disinfection using conventional UV systems. In fact, in almost all applications, conventional systems require the use of a softening system BEFORE the UV system in order to operate properly.

Now, UV Pure’s patented, automatic "self-cleaning" technology overcomes this operational challenge. Hallett™ systems can operate within a very broad water condition parameters. The chart below is a comparison of the operating parameters for a conventional system versus Hallett systems.

The data demonstrates that the Hallett system is able to operate in a much broader range of pre-treatment conditions than all conventional systems, which not only disinfects drinking water but also extends the life of softener bed media. This makes the Hallett system widely applicable for the disinfection of softener beds.

Mr. Rodriguez wants help nickel limits:

Does anyone know of a city or industrial user in Texas with a very low limit for nickel?

We're interested in finding out if anyone has had to use alternative limits for an industry that was not able to meet the limit for nickel, so that we may contact them and inquire specifics.  (Click here to post a reply)

Mr. Jais needs help with his desalter:

Our refinery has been running a crude that has high calcium content. We dilute the crude off with others before processing. The calcium removal from the desalter is satisfactory but the calcium is plugging up the water effluent line.

This crude is also by the way high in TAN. Thus it will have in combination calcium naphthenate. Does anyone have any experience of calcium naphthenate plugging the water effluent line?

We are controlling the PH to be around 6-8. But we dare not bring it down further.  (Click here to post a reply)
