Layne
Christensen Acquires Intevras Technologies, LLC
 Mission
Woods, KS -- Layne Christensen Company today announced the
acquisition of Intevras Technologies, LLC ("Intevras"), a
privately held holding company of Industrial Water Treatment
Processes located in Austin, Texas. The acquisition purchase
price was $5.5 million plus future incentives and was funded
from Layne Christensen's current cash balances.
Intevras focuses on the
treatment, filtration, handling and evaporative
crystallization and disposal of industrial wastewaters. With
two primary technologies, the EVRAS Evaporative System and
the Integra Automated Disk Filtration System, Intevras'
recent activities in the Barnett and Marcellus Shales
positions it as one of the leaders in the treatment and
disposal of heavy brine waters in the oil and gas markets.
Greg Aluce, Layne Division
President, said, "The Integra filter provides solids
separation to the five micron particle size, and the EVRAS
technology provides mobile evaporative reduction,
concentration and solidification of industrial waste
streams. The capability of the Integra filter to remove
solids to such low levels without changing media combined
with the ability of the EVRAS units to employ waste heat in
the evaporative process is a huge plus. Additionally, a
small footprint combined with mobility allow this technology
to be applied to shale gas water treatment as well as power,
food and beverage and municipal applications dealing with
re-use and waste minimization. This acquisition is
strategically aligned with Layne's focus on expanding our
water treatment offerings and residuals management
capabilities."
Thomas Lucario, CEO of Intevras,
commented, "This is an exciting time for all of us at
Intevras. With James J. Harris, the founder and inventor of
our technology, I look forward to being part of the Layne
Christensen family. The resources, experience and customer
base that Layne provides will help us expand our market base
not only in the oil and gas industry but in other industries
as well. Our goal is to make Layne the leader in Zero Liquid
Discharge applications."

Parkson's HiOx UltraFlex System
Generates Savings
 Fort
Lauderdale, FL -- Earlier in 2010, Parkson installed 304
HiOx® UltraFlex aeration panels at a wastewater treatment
facility located in Hidalgo, Mexico, 40 miles northwest of
Mexico City.
The cleaned wastewater is
subsequently used by a regional power generation station as
well as a local oil refinery. The existing wastewater plant
was no longer able to produce the required quantity of water
needed for these industrial applications.
The activated sludge treatment
plant was originally designed to deliver 700 LPS (16 MGD) of
treated water. However, water production had been limited to
250 LPS (5.7 MGD) and it was unable to produce the volume
needed to cool the thermo-electrical towers.
The HiOx installation has more
than doubled the plant's consistent delivery to 500 LPS
(11.4 MGD) and peak flows of 600 LPS (13.7 MGD), a 140%
increase. The increased water production will allow the
power generation end users to rely significantly more on
recycled wastewater versus the scarce freshwater.
"The Hidalgo installation has far
exceeded the customer's expectations. They have reduced the
horsepower requirement from 900hp to 700hp and often run the
plant with only a single 350hp centrifugal blower while
still meeting the required oxygen requirements. In addition
to more than doubling the plant's capacity, the HiOx
UltraFlex system has resulted in monthly savings between
$15,000 and $40,000," says Vipin Lillaney, Parkson's HiOx
Product Manager.
In addition to the 46% reduction
in energy use, via reduced power consumption coupled with
greater throughput, the plant has also experienced greater
treatment efficacy with a 96% reduction in BOD.
Besides the HiOx aeration panels,
Parkson provided two Aqua Guard screens with 6mm openings to
help protect the plant's operations and improve the panels'
lifespan.

Rotork Improves Welsh Water’s Drinking Water
 Bath,
UK -- Welsh Water is investing £200 million to upgrade its
water treatment works across Wales by 2015. This includes
the water treatment plant at Cwellyn, where Rotork
intelligent electric valve actuators have been installed to
control the flow through a new state-of-the-art extension to
the works.
The new plant at Cwellyn has been
designed and built by Black & Veatch Ltd, one of Welsh
Water’s Asset Management Alliance partners for water supply
capital investment schemes. The new treatment regime is
designed to clarify the water before it enters the existing
works in order to deal with changing raw water conditions
and consistently meet all water quality standards. Rotork
IQT direct drive quarter-turn intelligent electric actuators
have been installed to operate butterfly valves controlling
the flow of water throughout the new treatment plant.
Patrice Nadouce, mechanical
engineer for Black & Veatch at Cwellyn, explained that
Rotork was selected following a competitive bidding process.
The selection criteria included value for money,
reliability, low cost of ownership and operator familiarity.
All the Rotork IQT actuators are Profibus DP-enabled and
linked to an existing distributed control system (DCS) on
five two-wire bus networks. The operation of the plant is
supervised by a SCADA system designed by Oasis Engineering
Ltd.
Water from Llyn Cwellyn, some two
kilometers distant, gravitates to the new treatment plant at
a rate of up to 850 m3/hour. The flow initially passes
through inlet static mixers where coagulant is dosed to
maximize the performance of the DAF (dissolved air
flotation) process. The flow is divided into three identical
DAF streams, which consist of one Flocculator followed by
one DAF cell where particles in suspension are floated to
the surface to form a sludge blanket.
The clarified water is then
filtered through first stage RGF (rapid gravity filtration)
before being pumped to the existing treatment works through
Ultra-Violet disinfection to deactivate cryptosporidium.
The Rotork IQT actuators,
including some modulating units, control all valve
operations including the inlet works flow control, automatic
desludging of the DAF cells, automatic backwashing of the
RGF plant and the plant treating the effluent created by the
clarification and filtration processes.
The successful completion of the
upgrade project at Cwellyn will safeguard the drinking water
quality for 70,000 Dwr Cymru Welsh Water customers in the
Caernarfon area.

Aqua-Aerobic MD-4 Pilot Unit
Provides Onsite Analysis
 Loves
Park, IL -- The new MD-4 Cloth Media Pilot Unit is a
fully enclosed, Great Dane 53 foot, drop deck trailer.
At its core is a 1-disk Aqua MiniDisk® cloth media
filter with several aesthetic, operational and
functional upgrades providing greater flexibility for
each unique customer application.
The MD-4 unit includes a
fully equipped lab area with the ability to accomplish
on-site analysis for most operating parameters such as
total suspended solids monitoring, and particle size
analysis. It offers functional and operational features
such as variable speed drives, chemical
pre-conditioning, online flow and turbidity
measurements.
All are tied into a SCADA
(supervisory control and data acquisition) package. The
new pilot unit also features a VFD (variable frequency
drive) controlled influent pump that has greater
flexibility for custom influent needs such as solids
loading and pH adjustment prior to the filter, and the
ability to accept water from a customer supplied,
gravity-fed day tank. In addition to the pilot unit's
internal upgrade, the exterior features a full-color
graphic display of the technology.
Technology pilot
demonstrations can be beneficial by providing a snapshot
of essential process operating conditions and allowing
the customer to actively interact with the cloth media
technology as well as Aqua-Aerobic personnel. The MD-4
Cloth Media Pilot Unit demonstrates Aqua-Aerobic
Systems' on-going commitment to development of future
filtration projects and providing solutions to its
customers.

Mr. Henry needs help with
stripping ammonia:
Does anyone have any ideas
about stripping ammonia, or even oxidizing ammonia, in an
untreated effluent stream with high COD (5,000 to 15,000
mg/l) and some oils/fats/grease (200 to 500 mg/l).
Thanks,

application. The GDT™ Process has been proven to be
extremely efficient in dynamically transferring gases to
pressurized solution while removing unwanted entrained or
dissolved gases. The process makes it easy to install,
non-fouling pressurized system which provides the user with
the ability to contain and treat process off-gas.
