Water treatment
Decarbonise your wastewater treatment plant with CO2 and O2 : supporting future carbon savings in water treatment.
These examples of natural solutions help you decarbonise the environment by saving energy, carbon emissions and costs.
- The CO2 paradox: How CO2 can reduce the carbon footprint of a wastewater treatment plants while avoiding harmful emissions into water sources.
- Scaling up pure O2: How O2 reduces N2O emissions through digital process optimisation while increasing capacity without expanding the plant footprint.
Why use small essential gases in your water purification process?
- The intelligent use of essential gas molecules such as O2 and CO2 plays a vital role in putting the water industry on the path to a sustainable future.
- These natural solutions have the unique advantage of not causing additional emissions and waste to the environment, as is the case with conventional chemicals.
- It saves energy and carbon, which is why it is recognised as a future solution for the intensification of wastewater treatment.
- Water companies that produce recycled water or drinking water are showing increasing interest in using CO2, as it can demonstrate a reduction in carbon footprint.
- The use of O3 to treat micropollutants, bulk sludge and hard COD will appear in the future as a response to stricter legislation to meet the targets of the UK water environment regulations 2017.
- The ultimate goal of using essential small molecules is to help the customer achieve their Sustainable Development Goals (SDG's) and reduce their carbon footprint without compromising operational excellence.
Why choose Air Liquide for your water treatment gas installation?
High level of expertise and full support
- Experienced process engineers to assist you from design to implementation
Air Liquide is not a a molecule supplier, we also develop bespoke technologies that produce and/or use gases.
This means that Air Liquide supports its customers with the knowledge of its technical competence centre. They train the customer in the professional use of equipment and control cabinets. These chemical, mechanical or process engineers support the customer and optimise the design of their application.
- Comprehensive audits and follow-up campaigns
Apart from basic and design engineering, we also carry out extensive follow-up audits and campaigns. This includes analysis of your operations in order to optimise the process in a sustainable way. This is combined with follow-up campaigns for deeper support and assurance of implemented optimisations
- Process guide for the digitalisation of enterprise assets.
Finally, it is possible to assist the customer remotely thanks to Water 4.0 or the digitalisation of company assets.
What equipment does Air Liquide offer for water treatment?
In addition to standard gas equipment such as regulators, transfer stations, hoses and valves, a special fleet of gas injection equipment and static mixers has been developed for water treatment.
Combining quality gas with the right equipment for your process will result in the best performance. Our team analyses, advises and supports solution integration.
