Nephron’s New
Facility in
South Carolina
Lou Kennedy’s Vision of Economic
Growth in a Healthy Environment
Nephron Pharmaceuticals Corporation is a privately-owned,
global leader in the manufacturing of generic respiratory
medications. Headquartered in Orlando, Florida, the company
recently opened its newest facility in West Columbia, South
Carolina. The new building reflects Nephron President and
CEO Lou Kennedy’s philosophy about merging technological
innovation with business expansion strategies. Reinforcing
this philosophy by example, Nephron’s owners, Lou and
Bill Kennedy, liked both the economic and environmental
advantages combined with the technological innovation of the
Griswold Water Systems (GWS) proposal to deliver on the water
treatment and management requirements of the building’s
cooling system. The GWS offering will also contribute to the
LEED (Gold standard) certification of the building, which the
owners are seeking.
Water Treatment and Management.
GWS technologies include the WaveTM (chemical-free water
treatment), a conductivity actuated blowdown system, and a
low-energy-use basin sweeping system that employs centrifugal
separation to remove dirt and sludge. The GWS WaveTM always
includes InstAlertTM remote monitoring that wirelessly transmits
flow, conductivity, and cooling system operational status. This
suite of equipment to prevent scale, microbiological fouling,
and corrosion on the cooling system has resulted in impressive
results on this large cooling system*, as follows.
* System Capacity: 3,700 tons of
cooling operating 365 days/24
hours (2860 hours), system
volume of 18,500 gallons,
average load at 50% of design
capacity

WATER AND SEWER SAVINGS:
At Nephron, an increase in Cycles of Concentration (C of C)
from 9 under typical chemical treatment to 14 under GWS
technologies provided the following water use efficiency.
• S avings of 1,200,000 gallons per year water purchase:
• 5% savings of water purchase
• 36% savings of blowdown sewage fee, or 100% saving
of blowdown sewage fee if discharged to stormwater
• If benign blowdown is reused for non-potable use such as
landscaping, there is savings of 2,400,000 gallons per year
of water purchase:
• 10% savings of water purchase
• 100% savings of sewer fees
CHEMICAL ELIMINATION:
Not only are considerable economic savings realized, but
the positive impact on human health and the environment
is also substantial.
• 2
63 gallons (17 15-gal drums) of scale preventer and
corrosion inhibitor mix
• 150 gallons (30 5-gal pails) of non-oxidizing biocides
(highly toxic)
• 192 gallons (12 15-gal drums) of chlorine bleach
ENERGY SAVINGS:
Superior system cleanliness, lowest total bacteria counts
(TBC), and excellent solids management all equate to strong
energy savings. Only 20 thousandths of an inch (0.020”) of
foulant on heat exchange surfaces will increase energy usage
by 20%. Wave has provided clean heat transfer surfaces
at Nephron. A new tower will rapidly acquire a 0.020” of
foulant with chemical treatment. The 5% savings (a 400,000
kwh reduction) for this site at 12¢ per kWh is $48,000.
