Water, Wastewater Pumping
Trends and Solutions
Advancements in water treatment and plant modernization drive growth in the water
and wastewater pumping industry.

hile new construction in the municipal water-treatment
market has remained relatively flat, growth in the industrial
water-treatment market has increased-driven largely by modernization efforts that seem to be pervasive across the power-generation segment, according to Charles P. Crowley Company (CPC,
Baldwin Park, CA, cpcrowley.com) managing director Jon Crowley.
One trend that Crowley sees throughout the industry is modernization through "repowering."

REPOWERING PROCESS
The repowering process involves replacing old coal boilers with
gas-fired turbines that send heat to a heat-recovery steam generator
(HRSG), which feeds a steam turbine. These types of systems can
increase electricity production and overall efficiency of the plant by
as much as 40% more than coal-fired plants. They help plant owners
reduce costs-specifically maintenance costs-as newer, modern
systems are easier to work with, Crowley said. The switch to natural
gas results in other savings because feed stocks are abundant, less
expensive, and easy to transport to plant sites.

RELIABLE PUMPING SUPPLEMENT

For decades, plants in areas such as California and Nevada
have been at the forefront of the environmental movement. Many
have already made the switch to natural gas. Crowley points to a
global modernization effort that is following California's lead-as
plants in other parts of the United States, Mexico, China, India, and
elsewhere around the globe, are standardizing on natural gas.
Like all power plants, gas-fired plants require a lot of water. This
boiler feed-water must be treated to avoid scale, corrosion, and other
problems that damage or impede the boiler's performance. There
is a direct correlation between the quality of the water used and the
efficiency of the plant. Depending on the feed-water quality, varying
levels of pretreatment are necessary to remove impurities and suspended solids, and to adjust the water's pH to a neutral level.
Reciprocating and rotary gear pumps are widely used to inject
the precise dosage of chemicals needed for these applications.

WATER-TREATMENT SOLUTIONS
Most businesses in the United States have a need to treat the water
they use-whether they are food growers, juice makers, product
