Can Ozone Remove Pharmaceuticals in the Water?

Cosmetics, furniture, cleaning products, plastics and toys. In our modern world, there are very few products that do not contain chemicals. They undoubtedly bring huge benefits to mankind and society. We use pesticides and herbicides to protect our crops and increase food production for a growing population. We wear clothes made of chemical dyes and flame retardants. We rely on drugs to treat diseases such as cancer, depression, tuberculosis, and malaria.

The number is staggering. Today, there are approximately 150,000 different chemicals used for commercial purposes, and their number and applications continue to grow.

However, our understanding of the impact of chemicals and their use is increasing. Despite the benefits, chemicals can also cause pollution and pollution. They are everywhere: in the air, in the water and on the ground. They are found in the Arctic and the bottom of our oceans.

The presence of chemicals does not always mean that they pose risks, but chemicals in the aquatic environment at or above the level of concern may harm aquatic life and other wildlife supported by these environments. Over time, even low concentrations of certain chemicals can affect the health of animals and fish, such as interfering with the endocrine system and affecting reproduction. If certain thresholds are exceeded, other chemicals will have a more direct impact on aquatic organisms due to their short-term toxicity.

Both rural (pesticides, biocides and veterinary drugs, etc.) and urban (cleaning chemicals, transportation, cosmetics, etc.) are constantly creating micropollutants. It is a fact that traces of drugs are found in our underground waters, rivers, drinking water and wastewater and this contamination is not regulated to a large extent.

Ozone water Treatment

Ozone Generators – the prevailing technique for pharmaceutical removal

Today most wastewater treatment plants are not dimensioned to remove pharmaceutical residue. Estimates show that about 10% is eliminated at the treatment plants while 20% ends up in the sludge and as much as 70% ends up in the aquatic environment.

There are available techniques that efficiently reduce the level of pharmaceutical residue in our water. Conventional biological, as well as mechanical treatment methods, are not sufficient since a large part of pharmaceuticals are not degraded by these treatment methods. Ozone is a selective oxidant and primarily attacks electron-rich structures in molecules, such as double bonds, and is therefore efficient in breaking down pharmaceuticals.

Many studies show that up to 95% of the pharmaceutical residue can be removed with ozone, or even more depending on the dosage and retention time. A study performed by Primozone shows that ozonation, preceded by filtration, will remove up to 95% removal with 5 g O3/m3 water.

Ozone is a cost-effective solution

With the Primozone ozone technology, ozone can be used to effectively remove pharmaceutical residue at a low cost. Many customers are positively surprised by the low cost per m3 water treated.

How efficient is ozone?

Many studies show that up to 95% of the pharmaceutical residue can be removed with ozone, or even more depending on the dosage and retention time. A study performed by Primozone shows that ozonation, preceded by filtration, will remove up to 95% removal with 5 g O3/m3 water.

Studies also suggest that ozonation should be succeeded by sand filters to ensure even more effective cleaning of the water.
