The power generation industry recognizes Total Organic Carbon (TOC) as an important cause of corrosion
Organic contamination of pure water from power plants can cause a series of costly problems: it can foul the resins of
ion exchange in the makeup water and condensate deionizers, which requires more frequent cleaning and replacement of the resin.
TOC contamination found in water will convert to corrosive acids at higher pressures, which can reduce the life of boilers, reactors
and the turbine blades. High purity water is necessary for the continuous operation of power facilities.
UV TOC reduction systems are a solution to these problems (at 185nm wavelength) in a technology design.
low pressure lamps. This energy favors the formation of OH free radicals that lead to the oxidation of organic compounds.
present in the water.
Most common applications
Ultraviolet (UV) systems are used for the effective reduction of organics, commonly known as TOC (total organic carbon).
TOC reduction is achieved through a powerful 185nm wavelength UV system, appropriately designed and sized for compliance
of this application, as well as strategically located in combination with other equipment.
Carbon dioxide is a typical byproduct of the TOC reduction process, which results in a decrease in water resistivity. While the
Most organic molecules are oxidized into carbon dioxide and water molecules, other more resistant species are ionized or weakly charged,
after absorbing UV. Therefore, polishing deionization (DI) beds are typically placed downstream of TOC reduction units,
so that they not only remove charged/ionized organics, but also restore the resistivity of the water.

water for makeup or to feed reverse osmosis (RO) plants, Pall provides a wide range of quality influent water.
Cooling tower purge.
Treated cooling tower blowdown water can be recycled as makeup water for cooling tower, reused as feed
from the boiler, discharged or used to reduce the discharge flow (Zero Liquid Discharge objective). In short, treatment solutions
for your plant water, ensuring you can make the most of your water resources.
Boiler feed water.
With strict water treatment regulations and increasing demand for safe water, treatment systems must ensure strict compliance
of purity standards. Filtration is essential for your water treatment system to meet purity goals, and filtration methods
Traditional media such as sand and granular mixed media are often ineffective, labor-intensive and expensive. Membrane-based solutions offer a
Proven solution for your industrial water treatment needs.
