WATER & WASTEWATER
systems
microorganisms, and mineral scales accumulate on membranes. To extend the
life of the RO membranes, and to increase
the efficiency of the treatment process, a
wide variety of scale inhibitors is dosed by
metering pumps on the membranes.
"Precise dosing saves money on
chemical costs and also helps to prevent
calcium-carbonate scaling," Davis added.
"Without scale inhibitors, membranes could
become saturated with heavy elements that
reduce efficiency and clog the process in as
little as 48 hours. The metering pumps used
to dose the scale inhibitors play a key role
in maintaining the equipment."

MAINTENANCE
Many OEMs in the water and wastewater industry have their own maintenance
teams. When it comes to maintaining their
pumps, some customers know exactly what
spare parts they need. Others leverage the
expertise of distributors by outsourcing their
inspection and maintenance activities.
For example, CPC sells pumps and
skidded systems directly to power plants
throughout Southern California and
Nevada, and they also sell to large OEMs
that service the power industry around the
globe. These OEMs do not specialize in
maintenance. Much of the servicing and
repair work comes back to the distributor or
service company.
Because uptime is of paramount importance, the maintenance teams at power
plants demand a responsive distribution
network, with parts that are always in stock
and expert service technicians that can
respond in a moment's notice.
A majority of the water-treatment applications in power plants are best served by
rotary-gear pumps. Their seal-less design is
easy to maintain because there are no leak
points for harsh chemicals to damage the
pump or surrounding equipment.
Because every inch in a power plant is
valuable, plant operators prefer pumps with
small footprints. The trend is to move away
from horizontally laid infrastructure.

RELIABLE PUMPING SUPPLEMENT

MAKING WASTEWATER PUMPING
SYSTEMS SMARTER
In the wake of a renewed interest in federal investments in infrastructure, the
District of Columbia Water and Sewer Authority (DC Water) and Xylem Inc. (Rye
Brook, NY, xylem.com) partnered to highlight the urgent need for investing in
smart-water infrastructure to maximize operational productivity.
In a report released in early March 2017, the American Society of Civil Engineers (Reston, VA, asce.org) estimated that the U.S. needs to invest a minimum
of $123 billion/yr. in water infrastructure over the next 10 years to achieve a good
state of repair.
To advance research and development in the area of smart-water infrastructure and advanced data analytics in the sector, Xylem and DC Water expressed
a commitment to accelerating innovation through field-driven pilots that focus on
increasing the productivity of managing water and wastewater and improving the
resilience and sustainability of those operations.
"In the U.S., our water and wastewater infrastructure faces a daunting investment gap that places these critical systems at risk and leaves our communities
vulnerable to the consequences of system failures," said Patrick Decker, president
and CEO of Xylem. "We are so pleased to be able to partner with DC Water-a true
industry leader-to address these challenges, leveraging technology to develop
new, more sustainable solutions."
George Hawkins, CEO and general manager of DC Water, said, "At DC Water,
we're always looking down the road for the next innovation that will help us do our
job better, at less cost. This new technology accomplishes that and I'm excited
about the implications not just for us, but for the industry as a whole. It's also an
important demonstration of partnerships between the best elements of privatesector innovation and public-sector operational know-how, and I'm proud to be on
the forefront of this effort."
DC Water's service area covers approximately 725 sq. mi. and the enterprise
operates the world's largest advanced wastewater treatment plant with a capacity
of 384 million gal./day and a peak capacity of 1.076 billion gal./day.

"Vertical configurations are less susceptible to flooding, they are easier to work
on, and they don't require staff to crawl on
the floor to access," Crowley said. "The
ergonomic, front pull-out-designed pumps
can be repaired in place. This minimizes
downtime by eliminating the need to lock
out/tag out the pump and move it to the
repair shop-which, in some plants, must
be done by a separate union employee."
Maintenance activities can be further
streamlined by selecting pumps that require
a limited number of parts and with pumps
that use symmetrical parts that only fit one

way. This simplifies parts replacement and
keeps repair time to a minimum. RP
