About Dryden Aqua Our approach:
Who is Dryden Aqua? Prevent bacteria growth instead of
killing bacteria
We are marine biologists specialising in swimming
pool water treatment. Our mission is to eliminate
toxic chlorine by-products and provide the best air
and water quality on the market. For over 30 years
we have been working with chlorinated systems
for dolphins and other aquatic mammals before
successfully introducing our technology to the pool
industry. There are over 100‘000 swimming pools
worldwide using our products today.
Dr Dryden is a marine
biologist with a unique
knowledge combination
of biology, chemistry and
technology.
He is the developer of the
activated, bio-resistant filter
media AFM ® .
What does Dryden Aqua stand for?
We stand for the best water purification with crystal
clear water, minimal consumption of chlorine and
no chlorine smell or other harmful disinfection
by-products (DBPs). With Dryden Aqua integrated
water treatment system, we reduce the cost of
water treatment and combine a healthy swimming
experience with environmental sustainability and
economic benefit.

Swimming pool water treatment should prevent the
transmission of pathogens between bathers and
minimise harmful disinfection by-products (DBP).
Traditional water treatment methods attempt to
fight the transmission of pathogens by using more
and more powerful disinfectant chemicals, UVc irra-
diation and ozone. But the transmission of patho-
gens is a biological problem; it therefore needs a
biological solution.
The approach of the Dryden Aqua integrated
water treatment system does exactly that:
instead of using more and more powerful disinfec-
tants and expensive equipment, we design a pool
water treatment process that changes the water to
make it difficult for bacteria and parasites to live
and reproduce. We can achieve this task because
we are biologists. We know what bacteria need to
grow and we can remove it, this is a much better
approach than trying to kill them with chemicals
once the bacteria have become established in a
pool circuit. That is why we achieve swimming pool
water quality that is almost free of bacteria and
parasites.
Our approach is based on three critical elements:
1. As a consequence of our bio-resistance of AFM ®
bacteria have no substrate on which they can
grow and multiply.
2. We remove food for bacteria by advanced
coagulation, flocculation and filtration.
3. DAISY: our Dryden Aqua Integrated System
filters almost everything out of the water and
reduces the chlorine demand to the lowest
level possible. The lower the chlorine oxidation
demand the lower the concentration of chlorine
disinfection by-products in the water and in the
air just above the surface of the water.
Our DAISY system provides crystal clear and
healthy water without toxic disinfection by-pro-
ducts (DBP’s), lowest chlorine consumption and
low maintenance costs.
