UV TOC reduction effectively removes Total Organic Carbon, TOC, from water which is critical in many applications and processes.
What Is Total Organic Carbon, TOC?
TOC refers to the total amount of organic carbon
compounds found in water and is an important measurement to understand whether
water used in certain processes is of a pure enough quality. All untreated
water will contain some carbon compounds which can be introduced from various
sources.
TOCs may include synthetic, man-made compounds, and
altered or natural products from living systems. The presence of bacteria and
other TOC’s and water may suggest a failure in filtration, components, systems,
or storage. If TOC’s are left unfiltered these compounds may cause significant
damage to expensive equipment, or unwanted contamination in applications such
as semiconductor chip fabrication or pharmaceutical compound production. This
kind of contamination can impact not only product quality but also process
profitability.
Practicing
TOC reduction methods is critical to protect many industries, the environment,
and consumers. UVC germicidal lamps play an important role in
providing this protection.
When
Should TOC’s Be a Concern?
High-purity water is a key component in many
processes. Bacteria or other organic compounds can negatively impact product
quality, process profitability and process yield. TOC destruction equipment is
commonly seen in the following applications:
·
Food and beverage industry
·
Pharmaceutical industry
·
Microelectronics and semiconductor
production
·
Wastewater and stormwater treatment
How
UV TOC Reduction Works
Ultraviolet, UV, light has been used for over 100
years to remove harmful microorganisms such as bacteria and viruses from water,
air, and surfaces. UV light is an effective method of TOC reduction by
utilizing UV light to destroy and/or remove organic compounds through different
types of reactions. TOC’s can be reduced/eliminated with UV lamps through one
of two following methods.
One TOC reduction method involves the creation of
ozone via 185nm photons. These photons produced ozone which in turn oxidizes
organic compounds found in water. Ozone lamps can also lead the the formation
of hydroxyl radicals (-OH) , which are also very powerful oxidation agents.This
can lead to further beneficial degradation of organics found in a given water
source. This oxidation process is the primary UV chemical reaction occurring
from high-energy 185 nm UV lamps.
Another method of UV TOC reduction occurs directly
via photo-dissociation (photolysis) of organic molecules. In this TOC reduction
method, high energy photons (185nm and 254nm) physically decompose organic
matter found in a given water source.
Benefits
of UV TOC Reduction
There are many benefits of using UV lamps for TOC
reduction in addition to providing a reliable and effective method of purifying
water. UV germicidal lamp water disinfection systems provide a wide range of
benefits which include a high-level of microbial reduction and disinfection
with 254 nm and 185nm emissions.
Some of the most important benefits of UV TOC
reduction includes:
·
Germicidal effectiveness
·
Low operational expenses
·
Low maintenance costs
·
No harmful byproducts as with
chemical use
·
Can operate indoor, outdoor, and
water in the air
UV germicidal lamps by LightSources provide these
benefits and many others such as custom design solutions available to meet your
specific application requirements as well as proprietary technology.
