Linde Gases, a division of The Linde Group, has announced the launch of breakthrough waste water technology for cost effective recycling.

AXENIS™ is an environmentally sustainable water treatment process to turn industrial waste water into a re-useable utility.

The process, which employs a high rate biological treatment stage and uses oxygen and air for optimum process control allows for the cost effective recycling of waste water to extremely high quality standards - right up to potable quality.

Against a conventional waste water treatment solution, the innovative, patented process offers very substantial cost savings across the industrial water lifecycle.

These savings include much reduced capital investment requirements, which will be important for industries looking to capitalise on retro-fittable water treatment solutions versus commissioning newly constructed plants, and decreased energy costs as the new system requires considerably less power than air-based systems.

Additionally, because the treatment of waste water can be undertaken on-site, companies can mitigate the need to discharge waste water and the associated costs of paying an external water treatment company to dispose of it in compliance with statutory requirements.

The higher bioreactor temperature also increases membrane flux rates, which has the added benefit of reducing membrane surface area, making the unit extremely compact and saving on plant footprint.

“Linde has always had a strong heritage and pioneering role in developing environmentally sustainable technologies,” said Darren Gurney, Process Engineer for Water and Aquaculture at Linde.

“Our new AXENIS™ waste water treatment solution represents a real alternative for producers of high strength industrial waste water by delivering a highly convenient and cost-effective re-usable utility - and one that will have a vastly reduced impact on the environment.”
