A breakthrough advance in electrosynthesis of chemicals used for water disinfection
Advanced Diamond Technologies (ADT) is proud to market Diamonox, the first product of its kind that optimizes the power of diamond
for the electrosynthesis of oxidants for water treatment. Based on ADT’s award-winning UNCD® Electrodes, Diamonox Cells represent
a fundamental breakthrough in electrochemical technology, enabling a far greater level of robustness and performance than other
electrode/cell technologies are capable of achieving.
Diamond electrodes produce mixed oxidants -a mixture of chlorine- and oxygen-based chemicals known to be superior to ordinary
chlorine for water disinfection. Diamonox captures this capability in a simple cell design, which enables the on-site generation of mixed
oxidants with a degree of robustness that is impossible for other technologies:
•
Diamonox Cells eliminate the need for water softeners, heaters, and expensive salts. Diamonox Cells are self-cleaning and resist
scale buildup.
•
Diamonox Cells produce 3x to 6x more oxidants per electrode area compared to other cell technologies, reducing the size of the
cell volume by the same faction.
•
Diamonox cells energy conversion efficiency (ECE) are capable of producing oxidants with lower operating costs than other technologies. Using only standard free available chlorine (FAC) metrics which do not include the additional oxidative power of mixed
oxidants, Diamonox Cells can have ECE metrics of less than 3 kWh/lb FAC and salt costs below 15 cents per lb. FAC.
On-Site Generation
On-Site Generation (OSG) of oxidants for water treatment is based on the electrolysis of brines to produce chemicals used for the
disinfection of water. These chemicals include chlorine (hypochlroous acid + hypochlorite), bromate, persulfate, ozone, hydrogen
peroxide, percarbonnate, and others. Instead of transporting and storing these hazardous chemicals at the point of application, OSG
produces them on-site using only water, salt, and energy. This can lower the costs of water treatment, while also achieving better
disinfection performance which also creates a safer work environment.
Primary Applications of
Diamonox Cells & Systems
•
Cooling Towers
•
Desalination
•
Oil & Gas
•
Aquatics
•
Clean in Place
•
ASHRAE 188P
•
Ballast Water
•
Waste Water
In the past, the adoption of OSG has been hindered by the general lack of robustness of the technology. Diamonox solves this problem. Through the combination of improved efficiency, mixed oxidant performance, reduce maintenance costs and longer electrode life,
Diamonox can achieve lower operating costs and return-on-investment (ROI) metrics unreachable with other technologies. It also enables OSG to be used where existing technology cannot be applied due to problems with water quality or higher raw materials costs.

Diamonox Cells
ADT’s Diamonox Electrochemical Cell product line consists of undivided
(membrane free) electrochemical cells that share a common geometry and design.
The Diamonox Cell line incorporates UNCD diamond electrodes that enables
self-cleaning and a high-degree of tolerance to water conditions. The FAC generation capacity of the Diamonox Cells start from 1.0 lb/day and increases as needed.
Diamonox Cells are primarily designed for on-site generation of mixed oxidants.
They provide a robust, economic, and ecologically more attractive solution to
purchasing and storing chemicals such as sodium hypochloride for use in a wide
variety of applications including cooling towers, commercial pools, and water
used in oil & gas production.

Self Cleaning
The Diamonox Cell is self-cleaning by reversing the polarity of the cell for 1-5 minutes per 24-72 hours period of operation. The cleaning cycles can be conducted
much less frequently depending upon the specifics of the water and salt quality. Diamonox Cells have operated with tap water and common solar salt without need for
disassembly or periodic cleaning using muriatic acid solutions. No water softener is
needed to remove Ca or Mg from the input water.
