Power
Water is a critical ingredient in power generation. CWT'
products and services help the industry to meet the wide variety
of purified water and wastewater challenges.
CWT' water treatment systems are designed to meet the
power industry's requirements for high purity boiler makeup
water. Ultra pure water systems produce water which meets
the most rigorous specifications for nuclear steam generators,
coal fired supercritical systems, gas turbine combined cycle
facilities, gas turbine peaking plants, and co-generation
facilities.
CWT' membrane treatment systems, ion exchange (IX) and
evaporation technologies are used to meet the most stringent
water quality requirements. A variety of treatment systems
are also available for deoxygenation and removal of other
dissolved gases from makeup water to steam generation systems.
CWT' wastewater treatment reuse systems are able to convert
municipal wastewater for a variety of industrial uses, including
demineralized water. The ability to convert municipal
wastewater to high purity water helps power plant developers
eliminate water as a variable in plant siting while increasing
community goodwill by conserving local resources used for
drinking water.
Mining
Today's mining and smelting industries are faced with numerous
environmental issues regarding wastewater containment and
disposal. Many facilities have large holding ponds containing
mining wastes and some operations have contaminated groundwater
supplies with mining waters. Others facilities have wastewater
streams that often do not meet increasingly stringent discharge
limits.
Wastewater from various sources can be recycled to produce
high quality water for reuse. In some cases, valuable mining
by-products can be recovered for resale or reuse using CWT
membrane and thermal products systems. Examples of waste streams
requiring treatment include:
Containment pond leachate
Cooling tower blowdown
Demineralizer concentrate and regeneration wastes
High total dissolved solids (TDS) effluents
Mine drainage
Reverse osmosis (RO) reject
Scrubber blowdown

the mining and smelting industries. With a broad cross-section
of experienced engineers and chemists, CWT is well prepared
to solve your wastewater problems.
CWT offers comprehensive services including wastewater definition,
conceptual systems development, laboratory analysis, bench-scale
and pilot testing, equipment supply
and turn-key project execution. Whether it is maximum wastewater
recovery, waste minimization, by-product recovery, or zero
liquid discharge (ZLD), customers can have confidence in CWT
for the design and supply of the most economical and complete
solutions.
Microelectronics
CWT has cultivated a strong reputation in the microelectronics
industry for supplying the highest quality water treatment
equipment and turn-key ultra pure water (UPW) systems. Combined
with unparalleled operation and maintenance (O&M) services
and superior ion exchange (IX) regeneration services.
The microelectronics industry uses UPW, the primary silicon
wafer cleaning agent, to rinse circuits, channels, and gates
of the chemicals used in the manufacturing process. Inorganic
salts and organic matter remaining or deposited on the wafer
surface during processing directly affect the number of usable
devices produced from a silicon wafer. Rinsing with ultra
pure water can substantially increase plant production yield.
Since ultra pure water contacts the wafer surface multiple
times during manufacturing, water must be of the highest purity.
Water management and supply capabilities for the microelectronics
industry include:
operation and maintenance (O&M) services
Complete turn-key UPW systems
High quality ion exchange resin regenerations
Mobile emergency and supplemental UPW Systems
PVDF distribution loop designs and installation
Reclaim/recycle systems
UPW equipment including pretreatment, reverse osmosis (RO),
degasification, electrodeionization (EDI), demineralization,
ultraviolet sterilization, ozonation, and ultrafiltration
(UF)
Wastewater and chemical mechanical planarization (CMP) post
treatment systems
Product platforms include: standard or custom land-based systems
for permanent installations,
or containerized systems for mobile treatment, providing customers
the option to either purchase their UPW system or use CWT'
industrial water outsourcing services.
Chemical
In all refining and petrochemical facilities water is one
of the basic plant utilities. With the increase in demand
for refined energy products, the quality and quantity of refinery
water are crucial in sustaining plant output.
The quality of the plant water is critical in minimizing
plant outages and refinery equipment maintenance. For example,
the presence of oil in the condensate reduces the efficiency
of the boilers and increases the make-up volume required to
maintain continuous operation, while poor boiler make-up quality
also contributes to premature boiler component failure.
Considering that a high percentage of energy resource exploration
and refining is done in areas where water is scarce, the use
of technologies to save or reuse water helps plant production
by reducing a facility¡¯s burden on local water resources.
This improves the long-term production economics while extending
plant production capability without the need for additional
raw water supplies.
Water management capabilities include:
Boiler feed make-up
Condensate deoiling
Condensate polishing
Cooling water recycling and treatment for reuse
Primary water desalination and demineralization
Raw water pretreatment, coagulation, settling and filtration
Wastewater recycling and reuse

The world¡¯s water consumption rate is doubling every 20 years,
outpacing by two times the rate of population growth. With
persistent regional droughts, shifts of the growing population
to urban coastal cities, and the water needed for industrial
growth, it is projected that by the year 2025 water demand
will exceed supply by 56%.
Sea water desalination
To meet this growing domestic and industrial demand for a
safe potable water supply, there is a critical worldwide need
to better manage the existing limited resources with improved
water conservation techniques, the increased use of wastewater
reclamation, and the development of sustainable new water
sources.
Oceans make up 97% of the world¡¯s supply of water. Desalination
using seawater reverse osmosis (SWRO) membrane technology
has become a viable option for the development of new regional
water supplies.
CWT is the world leader in the supply of reliable seawater
SWRO membrane desalination systems. With years of seawater
SWRO desalination operating and maintenance expertise, CWT
leads the industry in its practical knowledge of SWRO membrane
design, SWRO membrane pretreatment design, SWRO membrane cleaning
techniques, energy recovery devices and the selection of material
of construction.
