First NSF Certified WTP Chlorine Generator

ANN ARBOR, MI -- NSF International today announced that Washington, Iowa is the first city to have its water treatment facility certified by NSF International to ensure its chlorination system meets all national standard requirements. By obtaining certification to NSF/ANSI Standard 61: Drinking Water System Components -- Health Effects, city officials are demonstrating their commitment to advancing water quality for more than 7,000 Washington residents.

John Hays, Superintendent of the City of Washington’s water treatment plant, built and installed the electrolytic chlorination system – the first NSF certified system of its type – for the city’s one million gallons per day (MGD) treatment facility. Electrolytic chlorination involves adding chlorine to drinking water to destroy disease-causing organisms, such as Cryptosporidium and Giardia.

“A few years ago, we began looking at alternatives to chlorine gas for both safety and cost concerns,” said Hays. “Electrolytic chlorination seemed to offer the lowest overall cost of capital investment and ongoing operational cost.”

The certification demonstrates that the product, when used with NSF 60 certified sodium chloride, will not add harmful levels of contaminants to drinking water. NSF also provides testing and certification of water treatment/distribution products to NSF/ANSI Standard 60 (treatment chemicals) and 61 (treatment and distribution products) for product manufacturers and water utilities.

“NSF has certified many manufacturers of chemicals and chemical-generating equipment so the City of Washington had many options to consider. The City opted to build their own chlorination system, and NSF was able to accommodate their needs and provide an NSF 61 Certification for this custom-built equipment,” said Dave Purkiss, general manager of NSF’s Water Treatment and Distribution Systems Program.

For more information on the City of Washington’s certification, or NSF’s testing and certification services, contact Rich Martin at 1.800.NSF.MARK, ext 5346, 734.769.5346 or martin@nsf.org.

NSF International, an independent, not-for-profit organization, helps protect you by certifying products and writing standards for food, water and consumer goods.

WWTP Replaces Septic Tanks in Fallujah

FALLUJAH, Iraq -- A new sewer system is taking shape in Fallujah. Involving hundreds of Iraqis in the workforce, it’s the biggest construction project the U.S. Army Corps of Engineers oversees in Al Anbar Province of Iraq.

Fallujah’s new facility will use the construction of pump stations trunk mains and a treatment plant to serve as the backbone for a city-wide system. This is the initial phase that will eventually connect every home in the city.

“That community has been relying on septic tanks and the raw sewage is making its way onto the streets and into the storm sewers going directly to the Euphrates River,” explains Michael Jakubiak, part of a team of U. S. Army Corps of Engineers involved with the project. “So you have residents downstream that are taking their drinking water from that contaminated source. This project will improve that situation.”

Jakubiak said his office meets with the various construction firms for some 13 separate contracts, city and Iraqi ministry officials on a regular basis to ensure issues are resolved and the project moves forward.

“It’s those city and ministry officials who will eventually take over operation and maintenance of the new sewer system and we want to make sure it meets their standards," he added. "They’re fully engaged and eager to see this project completed.”

Regarding the contractors, he pointed out, “we’re doing a lot of work to mentor them especially in the areas of quality control and safety. Those are two key factors we continue to emphasize.

”With the new system, two large pump stations will each have the capacity to handle 150,000 cubic meters daily. Fallujah’s sewage will be sent to inlet tanks at the waste water treatment facility, then aerated grit and oil removal tanks, onto 65-meter-wide aeration tanks, then settling tanks. The last stop is a chlorination contact chamber before being released to the Euphrates River.

“There’s no question the health of Fallujah’s residents will be benefited by this project. Our mission is to help the Iraqi people get back on their feet and I’m proud to be part of this effort,” said Jakubiak. He had been involved with sewer-related projects in Cary, N. C., prior to volunteering for a year’s duty in Iraq.

“This is a great assignment. We’re helping a community with real needs,” he said. “The local jobs created are a boon to Fallujah’s economy. Those workers know they’re making a difference.”

Zero Discharge : First RO WTP Brine Concentrator

Plainfield, IL -- HPD has been awarded the supply of the world's first brine concentrator system as a key component of a reverse osmosis (RO) drinking water plant at a zero liquid discharge (ZLD) facility. The new system will be installed by C. Overaa & Co. at the Deuel Vocational Institute (DVI) in Tracy, CA.

The new HPD system will use evaporation technology to treat 250 gpm of reject from the groundwater RO system, which is designed to provide drinking water to DVI. The brine concentrator will reduce the subsequent effluent stream volume by 97% and recycle high-quality drinking water back to the facility. The remaining 3% of the stream is composed of highly concentrated brine that will be sent to a small, on-site evaporation pond to achieve zero liquid discharge.

A mechanical vapor recompression (MVR) system will drive the falling film evaporator to concentrate the brine, which optimizes energy efficiency using less than 80 kWh of electrical energy per 1000 gallons of water evaporated. The brine concentrator will use seeded-slurry technology to minimize scaling in the system, which is challenging due to the feed stream composition.

This process is especially important due to the growing effort in California to conserve valuable water and in other arid regions in the southwestern United States where drought conditions strain local water supplies.

"C. Overaa & Co. is excited to be partnered with HPD to build a project using evaporation technology which will provide benefits to the people of California for our future water supply", said Kevin M. Triplett, Overaa Project Manager. "The importance of this new technology is very evident given California's past dry winter and the current voluntary water rationing in the San Francisco Bay Area."

Overaa's contract with the California Department of Corrections and Rehabilitation calls the construction of a new 800,000 gallon per day water treatment facility using the combination of a reverse osmosis and brine concentrator technologies, with four brine evaporation ponds. The new plant will treat water from existing groundwater wells to supply high-quality drinking water to the DVI facility.

Mr. Merida needs help with a distribution system:

I am considering using up to three existing circular tanks (2.3 m tall and 6.41 m of diameter) as trickling filters to treat say 500 m3/day of domestic wastewater, could somebody comment on his/her experience and his/her feeling about this application.

Besides several things to consider, one is that I would appreciate your help is about the distributing system, because the diameter of the tank is large (I have experience with tanks of around 2 m), and I wonder where can I find and buy a good distribution system.   (Click here to post a reply)

Mr. Deal needs help with his membrane plant:

Here is my situation. I have a 0.5 MGD Zenon membrane plant. The problem we have is that the blowers are designed to run no less that 30%. We are now running them at 32%.

We have two small process basins, one is the aeration basin, the other is the anoxic. If we run the denitrification pumps, we get a reverse effect due to the well aerated water from the aeration basin. If we don't run the denitrification pump, we have a build-up of solids in our anoxic zone.

Presently, the denitrification pumps are only run 2 days per week to "turn over" the anoxic zone. The nitrate readings look very good for about two days then they good seriously downhill. The alkalinity is in the 200 range, the pH is in the 6.9 range, and no chemicals are used other than caustic, but only when the pH levels drop.

Our lab results are good.
EFF BOD = ND
EFF TSS = ND
Fecal Coliform= ND

The problem rises from the INF readings.
INF BOD < 30
INF TSS < 200

There can be no equipment added, we have to work with what we have. All of our equipment is capable of double the design capacity. TSS in our aeration basin is approx. 5500 and it's designed to run at 10,000. plus we are only running half of the equipment until INF flows and concentrations come up.

Any ideas I can try? Even if they seem far out in left field.
