Clarithromycin removal from water

Our Nyex technology is effective in the removal of Clarithromycin from water. We previously removed Clarithromycin from different of municipal wastewater, successfully reducing the level of concentration by 96%.

We successfully reduced the concentration of clarithromycin in various streams of municipal wastewater from 0.27 µg/L to 0.01 µg/L, resulting in a significant 96% reduction.

Clarithromycin in Water:

Clarithromycin degrades slowly in water. This poses a significant challenge for its removal.

Its effects include:

Therefore, effective removal methods for clarithromycin are crucial to safeguard our water resources.


Harm to Beneficial Bacteria. Clarithromycin may not only target harmful bacteria but also affect beneficial bacteria necessary for ecological balance. This disruption can have cascading effects on the overall health and functioning of aquatic ecosystems.


Development of Antibiotic Resistance. Clarithromycin water contamination can contribute to the development of antibiotic resistance in bacteria. Antibiotic-resistant bacteria can then spread through water bodies, potentially affecting marine organisms and even human health if consumed through seafood.


Altered Microbial Communities. The presence of clarithromycin can lead to changes in the composition and diversity of microbial communities in water. This alteration can affect nutrient cycling, organic matter degradation, and other essential ecological processes.


Ecotoxicity. Clarithromycin can exhibit ecotoxicity, posing a risk to aquatic organisms. It may directly affect the growth, reproduction, and behaviour of marine life, especially sensitive species such as fish, invertebrates, and algae.


Food Chain Disruption. Clarithromycin can disrupt the natural food chains and ecological relationships in aquatic ecosystems. This can have a negative effect on aquatic organisms. This disruption can have far-reaching consequences for the entire ecosystem’s structure and stability.

Removal of Clarithromycin from Water

Several additional methods are currently employed to remove clarithromycin from water sources. One common approach is the use of advanced oxidation processes (AOPs), such as ozonation.

Does Ozone Remove Clarithromycin?

Ozone treatment is considered a reasonably effective method for clarithromycin removal from water. It works by breaking down the compound through oxidation.

Ozone is a hazardous chemical and requires special handling. It has a strong oxidizing potential, making it capable of degrading a wide range of organic contaminants, including pharmaceuticals.

However, ozonation may result in the formation of disinfection byproducts, which can have potential health implications.
Additionally, the high operational costs associated with ozone treatment can limit its widespread implementation.

Does GAC Remove Clarithromycin?

Activated carbon filtration for clarithromycin removal is a process that has been used for some time.

GAC (Granular activated carbon) has a porous structure that can adsorb pharmaceutical compounds, including clarithromycin, effectively.

In some cases, it is a workable solution for water treatment. The adsorbed contaminants are removed by periodically replacing or regenerating the carbon.

However, GAC has limited capacity, and the adsorption process will become less efficient over time. Regular maintenance and careful monitoring are necessary to ensure optimal performance.

GAC is not an environmentally responsible removal method either, as we detail in this article.

Clarithromycin is an antibiotic used to treat bacterial infections. Pollutants in water from over-prescription, inadequate removal from effluent and incorrect disposal methods are causing antibiotics to stop working. We removed clarithromycin from different streams of municipal wastewater, taking the level of clarithromycin down from 0.27 µg/L to 0.01 µg/L, which was 96% reduction.
