(San Antonio) selected Veolia Water Solutions and Technologies (Paris) to
supply a complete boiler feedwater system to its St. Charles refinery in Norco,
La. The treatment system will incorporate Veolia’s patented ACTIFLO®
Turbo clarification technology to treat water from the Mississippi River. The
clarified water will be used for cooling-tower makeup and service water, and
also will supply water for the new high-purity boiler feedwater-treatment
U.S. Geological Survey (USGS) last year announced that it
selected AQUARIUS Software, manufactured by Aquatic Informatics (Vancouver,
British Columbia), for water time-series data management. The new software
replaces the Automated Data Processing System and several other legacy software
packages USGS has used for time-series data processing.
centralizing real-time operations on the AQUARIUS platform, the USGS Water
Resources Division will optimize efficiency in the storage, processing, and
publishing of hydrological data collected from its 7400 stream-gauging stations
across the U.S.
first chose a customized version of the software in 2005 to develop consistent,
accurate, and defensible rating curves for computation of flow in streams and
rivers within the United States; now, it will be making it the primary platform
for hydrological data storage, processing, and publishing by 3,000 staff.
City of Springfield, Ohio,and its consulting engineering firm
Black & Veatch (Overland Park, Kan.) selected WesTech Engineering Inc.
(Salt Lake City), through its subsidiary WWETCO, to supply the largest
compressible-media filter in the world to the Springfield Wastewater Treatment
of the 378,500-m3/d (100-mgd) WWETCO FlexFilter™ will begin at the
facility this year. The filter will contain nearly 570 m3 (20,000 ft3)
of compressible media and will be used 20 to 30 times a year as part of a
high-rate treatment facility to treat combined sewer overflow events.
City of Batesville, Ark., chose to add post-lagoon treatment
for biochemical oxygen demand polishing and nitrification via moving-bed
biofilm reactor technology at its water resource recovery facility. This
project, which was awarded to Headworks BIO™ Inc. (Houston), is one of the
largest lagoon nitrification projects in the U.S., according to a company press
expansion requires that the facility increase flow capacity from 15,140 m3/d
(4 mgd) to 34,065 m3/d (9 mgd) and decrease ammonia nitrogen levels
to less than 8 mg/L at wastewater temperatures as low as 4.7°C.
additional parallel treatment trains will be built, each containing two
reactors. The first reactor will treat any remaining biochemical oxygen demand,
along with the ammonia nitrogen from the lagoons, and the second reactor will
complete the nitrification process. The system will employ the proprietary
high-surface-area ActiveCell® media to minimize its footprint.
Clarification will be achieved through dissolved-air flotation.
