Cooling water treatment
Biofilm growth may be wasting 20-30% of your Cooling tower's energy and chemical costs
How does biofilm deposits impact cooling towers?
Biofilm
and limescale deposits drastically impair the performance of the
cooling tower due to increasing chemical costs and maintenance costs.
Without
proper treatment, layers of biofilm build up wherever water runs
through piping systems. Algae, a common organism in biofilms, is
especially problematic in cooling towers, where sunlight accelerates its
growth.
Even a small accumulation of biofilm growth has an
insulating effect that reduces heat transfer and increases energy costs.
Scientific researches revealed that just 0.15 mm of biofilm can increase
energy costs by 6% in cooling towers. At 0.9 mm, that figure jumps to
35%.
Over time, the deposits can
also plug screens and filters in cooling towers, adversely affecting
the flow of water.
How can biofilm be treated?
The
use of chemicals is a common solution for preventing
and treating biofilm. One problem is the high costs for chemicals and the other is the harmful environmental impact of the blowdown containing biocides.
Our
NB technology can significantly improve the cooling water treatment, by applying air, oxygen or ozone nanobubbles in the
cooling water circulation, and the resulting OH radicals destroy the
biofilm deposits.
and disrupts future growth.
Benefits of NB treatment
Increasing heat transfer and energy efficiency
Reducing cleaning frequency
Mitigating biofilm and deposits
Eliminating odors caused by stagnant water
Lowering equipment maintenance costs
Extending equipment life
