Recognition Celebrates CCRO for Innovation
in Water, Waste and Resource Recovery
WILMINGTON, Del., May 18, 2023
/PRNewswire/ -- DuPont (NYSE:DD) recently received an Edie Award
honoring the benefits of its Closed Circuit Reverse Osmosis (CCRO)
technology in supporting industrial and commercial customers'
sustainability goals. DuPont's CCRO technology received the top
award in the Water, Waste and Resource Recovery category.
The Edie Awards celebrate business sustainability.
The team was specifically recognized for an exemplary project
conducted in the City of San
Francisco, which mutually solved multiple sustainability
challenge being faced by the City's transit system and Cordia, a
local producer of steam.
For nearly 60 years, San
Francisco had been pumping tens of millions of gallons of
water from an underground creek out of the transit system's Powell
Street Station. Meanwhile, Cordia had been purchasing
municipal drinking water to generate steam for customers and
buildings in downtown San
Francisco.
To ease pressure on municipal water supplies and help alleviate
regional water scarcity, Cordia implemented DuPont's DesaliTec™
CCRO technology to purify the transit system's drainage water to be
repurposed for the creation of steam. The solution reduced the
volume of water demanded from municipal supplies by 30 percent,
saving 30 million gallons of drinking water per year and meeting
the City of San Francisco's 2025
water reuse goal in one step.
"To solve our global water challenges, we need to shift our
mindsets to realize that all water has value. As demonstrated with
Cordia and the City of San
Francisco, even the most challenging water can be
transformed into an opportunity," said Alan
Chan, Vice President and General Manager, DuPont Water
Solutions. "We thank the Edie Awards for recognizing
our DesaliTec™ CCRO technology as critical to a future where
we sustainably optimize the circular nature of water."
"A critical consideration for water producers and water
consumers investing in new infrastructure is to balance the needs
of today with potential future changes in water availability and
regulations," said Kevin Clarke,
DuPont's technical leader for CCRO. "In the San Francisco project, the water feeding the
DesaliTec™ CCRO is comprised of a variable blend of the transit
waters supplemented with additional water sources—so the feed water
today could be different from the feed water a year from now. In
cases like this, a purification system able to accommodate
variations in temperature, feed concentration, water consumption
flow rates, and fouling and scaling conditions is
necessary."
Whereas traditional RO systems are typically designed to purify
water for specific, set conditions, Closed Circuit Reverse Osmosis
(CCRO) is inherently designed to embrace these changes. With its
flexible independent control over recovery, crossflow and flux, and
its data-driven intelligence, CCRO systems can operate from 42
percent to 98 percent recovery on a wide variety of water sources
and applications.
DuPont's water technologies help purify more than 50 million
gallons of water every minute around the world, enable water reuse
and recycling, desalination, and the safe access of both ground and
surface water. DuPont offers solutions to a variety of water and
sustainability challenges through a broad portfolio of water
purification and separation technologies including reverse osmosis
(RO) membranes, ion exchange resins (IEX), ultrafiltration (UF),
electrodeionization (EDI), nanofiltration (NF), membrane bioreactor
systems (MBR), membrane aerated biofilm reactors (MABR), and closed
circuit reverse osmosis (CCRO) systems. To learn more:
