GYRECAT products and solutions are based on photocatalysis, a new breed of hybrid AOP (advanced oxidation process) for water and wastewater treatment. The GYRECAT technology is a highly effective and energy efficient process for the destruction of water-borne organic contaminants and sustainable water management. The photocatalytic technology can be used as a single action product for water polishing or as part of a more complex process train or as ‘packaged plant’ to create new advanced treatment within the water and waste water sector to deal with contaminants of emerging concern.

The GYRECAT® technology is a highly effective and energy efficient process for the destruction of water-borne organic contaminants and sustainable water management. The photocatalytic technology can be used as a single action product for water polishing or as part of a more complex process train or as ‘packaged plant’ to create new advanced treatment within the water and waste water sector to deal with contaminants of emerging concern.
GYRECAT® systems meet the expanding global need for:
- Cost effective water decontamination
- The recovery and re-use of water
- Sustainably managing water at its point of use.
The photocatalytic approach of the GYRECAT® system demonstrates superior decontamination performance, commercial advantages, and cost, energy and carbon benefits.
GYRECAT® has been tested In real world field projects with leading corporates and engineering partners; when deployed on wastewaters that defeated membrane, ultraviolet, ozone and other treatment processes, GYRECAT® successfully achieved its performance targets, with operating and treatment savings.
GYRECAT® can reduce the costs of, or replace, existing water treatments, and provide other economic advantages to industrial and municipal customers in sustainable water and energy practices.GYRECAT® SOLUTIONS
CatalySystems Limited, who developed the GYRECAT® process reactors is a Company guided by its underlying commitment towards less wastage of the World’s depleting freshwater supplies through encouraging industrial users to consider minimisation of freshwater use through recycling and reuse within their manufacturing processes.
Since our formation in 2009, companies now take their water stewardship more seriously. This is due in no small part to increasing media exposure into shortages of clean fresh water. Irene Allcroft, Chief Executive of CatalySystems commented:
‘Companies are now more actively considering their water footprint along with their carbon footprint as part of their corporate sustainability agenda and within their framework of operating cost reduction for the treatment and disposal or reuse of their wastewater. Our hope is that our products and services can help conserve our naturally depleting water resources in some small way for future generations, in a cost effective way for our customers’.
Some, like chlorine, chemically attack or reduce certain types of contaminants.
Whereas, advanced oxidation processes (AOP), have the ability to decontaminate water by oxidizing organic contaminants. Of all AOP approaches, photocatalysis has been demonstrated to destroy or reduce the broadest spectrum of organic species for the lowest energy cost. After decades of proven results in research, photocatalysis has now emerged and has been commercialised for water applications.
Photocatalysis is the process that occurs when certain wavelengths of light interact with light-reactive materials called photocatalysts – specifically, wide-bandgap semiconductors.
Titanium dioxide (TiO2) is such a material and widely used today in cosmetics, to brighten certain food products, in paints and a myriad of other uses. In water, in a reactor, when this catalyst is exposed to ultraviolet light, electronic processes in the material produce extremely reactive oxidizing and reducing species, which can break organic molecules.
The result is that pesticides, toxins, bacteria and other contaminants are destroyed, leaving only water, carbon dioxide and inert minerals.
The GYRECAT® is uniquely effective against a very wide spectrum of organic compounds, making it suitable against contaminants from oil, food, and other industrial processes, as well as bacteria and other pathogens, herbicides and pesticides.
CatalySystems technology is based on a class of AOP system, utilising photocatalysis in the presence of low energy UV light and a proprietary catalyst format, currently based on titanium dioxide. CatalySys GYRECAT® product range can offer superior performance over other AOP systems utilising photocatalysis with titanium dioxide.
- Other AOP photocatalytic systems tend to use a slurry-based Ti02, which is more susceptible to poisoning from contaminants, and thus have a shorter operational life;
- Such systems generate significantly more sludge as a by-product which requires subsequent treatment/removal by others.
- Our GYRECAT® range has lower power requirements (less than 0.3kW/m3)
- Our GYRECAT® range offers a smaller footprint
- Our GYRECAT® range offers lower O&M costs
CatalySystems reactors have been demonstrated to be effective in removing high levels of MTBE, toluene, xylenes and other soluble organic contaminants, as well as toxins and bacteria. The system has been designed to enhance existing primary/secondary treatment processes, e.g. where a biological treatment system is in operation, our units can be used post the biological reactor, and water can be recycled back into the inlet for the biological treatment to help protect and increase the efficiency of the biological reactor. Our technology can be used in a similar manner with RO and UF, to help prolong membrane life, thus reducing energy and OPEX costs.
