One-step Wastewater Treatment: COORTech Reactor System
In the manufacture of textiles, clothing and leather goods, using a nanoparticle catalyst this one-step wastewater treatment system activates a powerful oxidiser. This produces sulfate radicals in the wastewater which will degrade the inorganic pollutants. These highly reactive nanoparticles are immobilised in a special system, allowing for the re-usage of effluent water in one continuous process. Thus, less input water is necessary to achieve effective treatment, reducing the cost of purifying large volumes of wastewater.
The COORTech Reactor System developed at the Cape Peninsula University of Technology is a one-step waste water treatment system consisting of highly reactive nanoparticles immobilized in a specialised reactor system for the purpose of treating industrial wastewater resulting from the manufacture of textiles, clothing and leather goods. The system utilizes a nanoparticle catalyst, which activates an oxidizer in order to produce sulfate radicals that attack and degrade inorganic pollutants (such as dyes) in the wastewater. The system allows the re-usage of effluent water in one continuous process, thereby reducing the use of input water and lowering operating cost.
This technology eliminates the extra operating step and cost of removing catalyst residues and sludge from the effluent water. The system does not produce by-products which fouls the membranes, and thus the effluent water can be reused multiple times. The reactor operates at a competitively low pressure (max 4kPa) relative to membrane technology, which requires a minimum pressure of 100kPa. The COORTech reactor can be incorporated into existing wastewater treatment plants.
Due to the low pressure which the COORTech reactor operates (max 4kPa) being significantly lower than that of membrane technology, (requires a minimum pressure of 100kPa) this technology can be said to be superior in its field.
A reactor that would cause the breakdown of inorganic matter in industrial wastewater but does not require high pressures to operate.
