FOR IMMEDIATE RELEASE
Silanna
UV to Demo Innovative UV-C LED Water Quality Sensors at AQUATECH 2023
Detects
Nitrates and Organics Rapidly – Environmentally Safe, Low Power, and
Long Lifetime
Brisbane, Australia, 19th
October, 2023 - Silanna UV will demonstrate innovative new
technology for detection of nitrates and organic compounds in water at
AQUATECH Amsterdam from November 6 to 9, 2023. Contamination of water
by nitrates and organic compounds is a growing problem, and regulations
to protect the public from this threat are increasingly stringent.
At AQUATECH, Silanna UV will showcase its SF1 series of Ultraviolet
LEDs, which are ideal for water purity applications such as nitrate
detection, organic compound detection, disinfection, and HPLC
chromatography. Silanna UV is a pioneer in developing patented UV LED
technology for shorter wavelengths, from 230nm to 265nm, including deep
UV-C and far UV-C ranges.
The SF1 series achieves a peak wavelength under 235nm and a
Full-Width-Half-Max (FWHM) peak of 10nm, which enables high sensitivity
and accuracy for measuring low levels of dissolved nitrate and other
contaminants in water. The SF1 series also offers a long lifetime of
more than L50 >9,000hrs (>1 X 109) measurements, a low
power consumption of less than 0.12W, and a compact and robust design.
Better
Technology for Cleaner Water
Nitrate contamination in drinking water can be harmful to humans,
according to the United States Environment Protection Agency, the
Minnesota Department of Health, and other respected organizations. With
increasingly strong regulations that demand nitrate limits as low as
10mg/L-N, the need for monitoring and controlling dissolved nitrate is
now a priority in water supply.
In traditional Nitrate and Nitrite detection, broadband light generated
by a lamp is passed through an expensive spectroscopic pathway to
extract only the far UV-C wavelength needed for sensing applications.
However, this is complex, wastes power, and may require
environmentally-harmful materials.
In contrast, narrowband UV light under 240nm is perfect for this
application. Silanna’s SF1 series of LED UV-C emitters with peak
wavelength under 235nm and a Full-Width-Half-Max (FWHM) of 10nm makes
them an ideal candidate for a new generation of nitrate sensing devices.
Ready-To-Go
Nitrate-Detecting Reference Design
At AQUATECH Silanna UV will demonstrate its nitrate-sensing reference
design, which uses the 235nm SF1-3U8P3L1 UV LED emitter in a parabolic
lens package that produces a quasi-collimated far UV-C beam.
The reference design detects dissolved nitrate in a water sample in
only 0.5 sec, with effectively no warm-up delay. This reduces power
consumption and allows high-precision results as frequently as once per
minute for most applications. The results, including units of mg/L-N
(PPM of Nitrogen in nitrate), are displayed instantly on the clear
2.8-inch touch screen. The reference design is cost-effective, power
efficient, environmentally friendly, mercury-free, and incorporates a
safety interlock to protect users from UV-C exposure.
In addition to nitrate detection, Silanna UV will also demonstrate the
detection of organic compound contamination via Chemical Oxygen Demand
(COD) and UV254 absorption tests. These tests help monitor water
quality and prevent potential health risks from harmful substances such
as pesticides, herbicides, pharmaceuticals, and industrial chemicals.
