It's a wrap!
WEFTEC.08 drew a record 21,950 attendees and 1,111 exhibitors to the
McCormick Place Convention Complex in Chicago from October
18 to 22, 2008. The technical program featured 115 technical sessions,
31 interactive workshops, 10 facility tours, the Operations Challenge, and several other special events.
Visit our
two-page Photo Diary featuring some of the new technologies
showcased and some familiar faces from WEFTEC.08.
In addition to visiting as many WEFTEC.08 booths as possible, the Water Online team also took the opportunity to meet with our readers — old and new — at our booth. We also held a giveaway for attendees and Web site entrants who registered to receive our newsletter. Congratulations to
Scott Murphy, from Morrison-Maierle Consulting Engineers, who won
a Garmin nüvi 760 GPS.
See you next year in Orlando! |

New Luminescent Technology Brings Faster, More Accurate CBOD Analysis
By Bob Dabkowski, Wastewater Specialist, Hach Company |
| The city of Tyler, TX, has two wastewater treatment facilities that together serve upwards of 150,000 people. The smaller of the two plants, the Southside WWTP, is an activated sludge plant that uses mechanical aeration to achieve advanced secondary treatment. The nine MGD (million gallons per day) facility, with an average daily flow of more than five MGD, serves approximately 40%
of the city's service area. Carbonaceous biochemical oxygen demand
(CBOD) testing at the Southside facility is one of the plant's most
critical measurements. The test had long been a
troublesome and time-consuming procedure due to
inefficiencies inherent with the dissolved oxygen (DO)
probes the facility had used over the years... |

Innovative Wastewater Treatment And Recycling Solutions Are Flowing From Israel
By Oded Distel, director of Israel NEWTech |
| Israel, a country dealing with an increasing urban population and located in an arid climate, has by necessity developed into a global leader in the recycling and purification of wastewater. However, the environmental conditions and human challenges that Israel faces are by no means specific to Israel. Much of the United States faces these same pressures, making the adoption of Israeli water-quality technologies an attractive and pragmatic solution for solving problems in the wastewater and water-quality
field... |

C3 Series, UV open-channel wastewater disinfection system uses ultraviolet light to disinfect wastewater and prevents the spread of waterborne pathogens to lakes, streams, rivers, and coastal
waters.
The Parkson DynaLift Membrane Bioreactor System combines energy-efficient, airlift-assisted,
ultra-filtration Norit X-Flow tubular membranes with a simple biological wastewater treatment plant to provide extremely high-quality effluent for beneficial
reuse.
SewerCAD easy-to-use interface, automatic design features, and stunning presentation tools help you spend more time engineering better sewer collection
systems.
The Signet 2552 Magmeter Flow Sensor is a heavy-duty, high-performance sensor in an adjustable-insertion configuration that can be used with a ball valve for hot-tap installations. This insertion-style flow sensor has no moving parts, and
it is constructed of corrosion-resistant materials to provide long-term reliability with minimal maintenance
costs.
The downflow brining principle ensures consistent brine saturation. As influent water rises, higher density brine sinks. Sludge from rock and solar salt is concentrated at the bottom of the Bryneer where it can be periodically
removed.
The
Forty-X disc filter from Siemens Water Technologies is the
ultimate barrier in tertiary filtration. It captures more
solids in a smaller footprint, with a pleated media design, and
has evolved to incorporate extras that are important in
woven cloth media filtration.
The IFM series meets the needs of wastewater managers in preventing trash and inorganic solids from entering their bioreactors. The fine separation capability (down to 250 micron) of this unit makes it ideally suited to protect MBRs and to remove those irregularly shaped solids that work their way through downstream
processes.
The TOP fiberglass pump station from ITT Flygt Corporation is a premium, pre-engineered, and factory built packaged pump station that utilizes advanced features to provide customers with superior pump station
performance.
The OI Analytical Aurora 1030W TOC Analyzer processes aqueous samples for analysis of the total organic carbon, total inorganic carbon, and nonpurgeable organic carbon content of the
samples.
The Rotamix Process Mixing System uses state-of-the-art solids handling equipment and technology to provide the best in hydraulic mixing systems for digesters, sludge storage tanks, sludge blend tanks, equalization basins, and anoxic
zones.
NEOSEP is a new-generation membrane bioreactor that uses enhanced biological treatment (activated sludge) and immersed membrane filtration to produce water quality suitable for recycle and reuse in municipal and industrial
applications.
This compact reactor is available in multiple configurations to treat a wide range of flow rates. The streamlined, hydraulic profile of
closed-vessel systems disinfects filtered effluent without breaking head in the treatment
process.
The Model GC52 is a uniquely compact, wet/wet differential pressure transmitter, ideal for flow and tank level applications where reliable, low DP measurements are required. Equipped with the patented SiGlas 316 stainless steel isolated sensor, the GC52 can monitor a wide variety of wet or dry
media.
The
DensaDeg Clarifier/Thickener is a high-rate solids contact clarifier which combines optimized flocculation, internal and external sludge recirculation, and plate settling in two conjoined vessels to achieve very high hydraulic loading and treatment
efficiencies.
The DIMMINUTOR provides the first line of defense in a wastewater treatment plant headworks or pump station. Sewage solids are captured on a curved screen where rotary cutters sweep them into adjacent stationary cutters with a continuously rotating high torque
action.
CHEMetrics,
Inc. manufactures a quality, cost-effective line of reagent vials for performing Chemical Oxygen Demand (COD)
analysis.
Philadelphia Mixing Solutions Raven 3800 Series has earned a reputation as the leading manufacturer committed to providing superior mixing solutions to the
municipal and industrial mixing communities.
The ClorTec on-site hypochlorite-generating systems range in capacity from 6 to 3000 pounds per day, easily generating a 0.8% sodium hypochlorite solution by combining three common consumables — salt, water, and electricity — to produce a chlorine
equivalent.
