A SIMPLE SOLUTION FOR THE
TOUGHEST WASTEWATERS
——----— Diamox is a compact and easy-to-implement electrochemical
advanced oxidation reactor that provides on-site wastewater treatment
systems with game-changing efficiency and simplicity.
PERFECTING A TECHNOLOGY THAT
TRANSFORMS WASTEWATER TREATMENT
Diamox diamond electrode cells use proprietary solid
boron doped diamond (BDD) to give small to medium
volume wastewater treatment systems a transformative
increase in efficiency and capability.

Diamox electrochemical cells enable manufacturers
of on-site wastewater treatment systems to design
solutions that:
Conventional treatments use aerobic biological
processes to digest contaminates dissolved in waste
water. Highly contaminated effluent streams pose
a challenge for these processes since the dissolved
species can be resistant to oxidation (recalcitrant),
and can be toxic to the microbial colonies in a
bio-digesting plant.
–– Effectively treat effluents that are difficult or impossible
to treat by conventional means, by fully mineralizing
dissolved organic compounds
–– Allow discharge of treated water directly from site
–– Are cost effective and simple to operate and maintain
Advanced oxidation processes (AOPs) provide an
on-site solution for these challenging waste streams.
They function by mineralizing dissolved effluents
through oxidation reactions with hydroxyl radicals.
–– Avoid the need to use UV and chemicals
–– Meet the needs of key industries such as chemical,
pharmaceuticals, oil and gas, textiles and
environmental water management
THE POWER OF THE HYDROXYL RADICAL
The hydroxyl radical (•OH) is the neutral form
of the hydroxide ion (OH−). Hydroxyl radicals
are highly reactive, able to oxidize even the most
recalcitrant and toxic dissolved effluent species.

Diamox is a complete ‘bolt-in’ unit comprising a
Diamox cell with solid BDD electrodes, housing and all
electrical and pipework connections - ready to install into
Electrochemical Advanced Oxidation Process systems.
EXTENDING ELECTRODE LIFE FOR YEARS
Conventional electrodes dissolve in the presence of
the hydroxyl radical giving them a limited field life.
Element Six Electrochemical Processing (EP) Grade
BDD electrodes are resistant to the hydroxyl radical
and have a field life measured in years – enabling
EAOP systems that are efficient and reliable.

ELECTROCHEMICAL PROCESS
AOP systems usually require additional UV and
chemical processes to generate the hydroxyl
radical and that makes them more complicated
to operate, more hazardous and less sustainable.
Electrochemical AOP systems with long life
Diamox electrodes can generate the hydroxyl
radical solely by electrochemical means to treat
highly contaminated water; for a system that is less
complicated, safer and easier to operate.
Diamox has proven reliability and
is easy to integrate into your water
treatment technology.
Diamox contains a stack of bipolar
BDD electrodes to maximize the
effluent’s exposure to oxidizing species
generated at the electrode surface.

EAOPs are compact and simple water treatment systems.
The effluent is held in a process tank and then pumped
through the Diamox cell. The oxidation process is a batch
process with the dissolved effluents mineralized at the
surface of the anode electrode and the process controlled
by the power applied to the electrochemical process.
Diamox uses BDD for the anode and the
cathode. The designed allows for switching
the polarity of electrodes to prevent fouling,
enabling operation in highly contaminated
environments.
