Zero Liquid Discharge System for Golf Course Irrigation WTP
Water Treatment Systems, Inc. has recently commissioned a brackish water 1.2 MGD (4.5 million liters per day)
reverse osmosis water treatment plant
for a Texas, USA golf course community. In addition to providing irrigation
quality water, another goal was to recover as much of the concentrate as
possible, or, “Zero Liquid Discharge”.
The WTS design has achieved approximately 98% recovery.
This is a very important development
for the Golf industry. In many parts of
the country, and indeed worldwide,
golf course managers struggle with the
problems of availability, cost, or quality of water for irrigation of their golf
course property. Reverse !"#!$! has
solved the problem of utilizing brackish groundwater for irrigation. Unfortunately, many Golf Clubs that plan to
purchase % water treatment plants
run directly into a major obstacle. The
problem is &'($') a suitable location
to send the % concentrate water.
The lower the amount of % concentrate, the smaller the problem is.
The Texas % *+, is producing high
quality water for irrigation. Daily product
water production is 1.2 MGD. Daily concentrate production is 19,728 based on
24/7 operation. 0/1233 system recovery
is 98%. The membrane systems are arranged in three stages. The second and
third stage trains utilize concentrate water as their feed source.
The original design for the Texas Golf
Club called for zero liquid discharge
with the use of evaporators as the &nal treatment phase. Evaporators are
expensive both in capital and operat-
ing cost. But our client was fortunate
to obtain permitting for approximately
5% of the concentrate thus eliminating the evaporation phase which
saved about a million dollars. The
(nearly) zero liquid discharge design
by Water Treatment Systems, Inc., using membrane systems is a lower cost
investment for golf clubs everywhere.

GE’s 15,000th 1.5 Megawatt Wind Turbine Supports Training of
Future Wind Technicians at Basin Electric’s Crow Lake Wind Farm
GE announced on February 3, 2011
that its 15,000th 1.5 megawatt (MW)
wind turbine has been installed at Basin Electric Power Cooperative’s Crow
Lake wind farm in South Dakota, USA;
one of 108 GE 1.5 MW turbines recently
commissioned at the site. The turbine,
which will be owned and operated
by Mitchell Technical Institute (MTI)
through an agreement with Basin Electric, will provide hands-on learning opportunities for students enrolled in MTI’s
Wind Turbine Technology Program.
“The shipment of our 15,000th 1.5
megawatt wind turbine demonstrates
the key role that this technology has
played in supporting the rapid development of the wind industry in North
America and worldwide,” said Victor
Abate, vice president-renewable energy for GE Power & Water. “We are
pleased to know that this milestone
turbine will help to support future green
64
ARAB WATER WORLD (AWW)
technology jobs and will be instrumental to the training of the next generation of wind turbine technicians.”
The project was made possible by a
grant awarded to MTI by the U.S. Economic Development Administration.
Additional funding was provided by
the South Dakota Governor’s -&./ of
Economic Development, Basin Electric
Power Cooperative, General Electric
and MTI. MTI’s Wind Turbine Technology program, launched in 2009, provides highly trained technicians to the
expanding wind industry.
Construction at Crow Lake, which has
generated 200 construction jobs, according to Basin Electric, began in .tober of 2010. The Crow Lake project
spans three counties in South Dakota
and is the largest wind project in the
United States owned solely by a cooperative, with a capacity of 151.5
megawatts.
March 2011 / Volume XXXV Issue 3
Basin Electric, which serves 135 rural
electrical systems in nine states, including East River Electric Power Cooperative, Madison, S.D., is a recognized
leader of wind energy development
in the Upper Midwest and has added
approximately 451 megawatts of wind
energy to its energy portfolio in the
past decade.
