Caffeine removal from water

Caffeine absorbs really well onto our Nyex media inside our Nyex Rosalox system. Then a small electric current is passed through the media, effectively breaking down the caffeine (transforming it into water and gas) that is safely vented away.

Our technology has successfully reduces Caffeine concentration in wastewater to 0.01114µg/L.

Caffeine removal by GAC

GAC-based systems are widely employed for caffeine removal from water due to their effectiveness in adsorption.

GAC acts as a sponge, capturing and removing caffeine molecules from the water.

However, this method has its drawbacks. Over time, the carbon bed becomes saturated with caffeine and requires replacement or regeneration, leading to increased operational costs.

Furthermore, the spent carbon bed, containing toxic substances, poses disposal challenges and environmental concerns.

Caffeine removal by ozone

Ozone treatment is another method used for caffeine removal from water.

Does ozone remove caffeine from water? Ozone, a powerful oxidizing agent, breaks down caffeine molecules into harmless byproducts through a process called oxidation.

Although ozone treatment can effectively remove most caffeine, it does present challenges for operators. Ozone is toxic and requires careful handling to ensure the safety of personnel.

Additionally, ozone treatment systems can be expensive to install and maintain, making them less economically feasible for some applications.

Caffeine is a stimulant affecting the central nervous system. Caffeine is often found in medications to treat or manage drowsiness or migraines. It is not naturally occurring, but is found in the environment in low levels due to our bodies not fully metabolising it. Our technology can reduce caffeine concentrations in wastewater to 0.01114µg/L.
