Diamonox Technology - The Water Treatment Solution for Extremely Tough Water
Advanced Diamond Technology (ADT) has developed Diamonox® Technology that leverage the properties of diamond for water purification across a multitude of industries. Diamonox Technology is a transformative, unique, disruptive product that is a breakthrough solution for the water treatment while virtually eliminating environmental concerns.
Centered on one of the most innovative materials in nanotechnology developed at Argonne National Laboratory, ultrananocrystalline diamond (UNCD®), Diamonox Technology is applied in complex water treatment situations where conventional technologies alone cannot do the job. UNCD-coated niobium electrodes exploit the unique properties of diamond such as durability, chemical inertness, and resistance to abrasion, and they also exhibit extraordinary electrochemical properties. Combined with the principle of electrolysis, these properties constitute Diamonox Technology, which can operate in unconventional and tough situations for the complete and environmentally friendly removal of pollutants.
Diamonox technology works best where other technologies struggle. The complete destruction of highly refractory organic contaminants in water is a taunting task for the entire water treatment industry. Diamonox technology enables the complete destruction, mineralization of toxic organic compounds (some of the most toxic pollutants include for instance biocides, pharmaceuticals, solvents, and petroleum hydrocarbons) that otherwise would have to be remediated using inefficient technologies. Diamonox Technology is capable of generating some of the most powerful oxidants that can attack refractory organics and completely destroy them.
The power of Diamonox technology is also employed for the deactivation and destruction of bacteria, chlorine-resistance waterborne pathogens, and biofilms. The superior electrolytic properties of diamond enable Diamonox technology to generate a powerful verity of mixed oxidants (MOX). MOX contains high-order oxidants that can be generated directly from the salty water on demand and on site, essentially removing the need store or transporting toxic biocides.

The above video illustrates the power of Diamonox® Technology for the treatment of water typically found in tailings ponds used for the extraction of heavy oil. Open mining and SAGD operations utilize tailings ponds as a necessary method for recycling water. However the dewatering process can be considerably long (5 to even 20 years) because naphthenic acids render the clay (fines in the order of 2-3um) oil wet, trapping the water and preventing evaporation. Consequently, due to the large amount of water used, tailings ponds tend to be substantially large.
Diamonox Technology can process this water in a mater of minutes. The Diamonox® AOP process destroys the naphthenic acids that are bound to the clay, which becomes water wet. The emulsifying properties of the naphthenic acids is greatly diminished. As the clay settles at the bottom, the toluene also clarifies as less oil-wet clay is present. At the end of the process, about 10-12 minutes, the toluene is clear and recoverable, while the great majority of the clay settles at the bottom.
Diamonox Technology can have great benefits for the treatment of tailings ponds water: 1) clay settles faster to the bottom enhancing the dewatering process. This will result in smaller tailing ponds with much shorted residence time. 2) the bitumen/toluene can be recovered. About 3% of the tailings waters contain residual bitumen trapped in the clay. Diamonox can enable the recovery of the bitumen. 3) Naphthenic acids are destroyed significantly reducing the toxicity level of the remaining water.
The water shown in the video is a synthetic mixture trying to simulate the actual conditions of the tailings ponds. It contains brine and toluene in a 1:1 ratio, 1wt% kaolinite, and 100 ppm sodium naphthenate. The color chance of the water is partly due the oxidation of Si and Al contained in the kaolinite.
