waterPharmaceutical residue and other micropollutants are creating new challenges in wastewater treatment as well as environmental concerns.

Water treatment and ozone technology company Primozone has been working with reduction of micropollutants in wastewater during the last year and has identified a need for increasing the knowledge about the problem and the available solutions. To this end, the company has launched a new knowledge-site,, that covers the issue of reduction of micropollutants in wastewater.

Micropollutants refer to substances like pharmaceuticals and personal care products (PPCPs), hormones, pesticides and industrial chemicals. Residue from these can be found in water bodies everywhere.

Micropollutants are persistent and bio-active. This means that they are not completely biodegradable and cannot be removed with conventional wastewater treatment technologies. But there are many different water treatment solutions available.

The site can help water treatment professionals find relevant information on treatment technologies in one place, says Anders Schening, Primozone CEO.

In 2014 Primozone received funding to build a mobile pilot scale ozone system for removal of pharmaceutical residue. The aim was to be able to prove the concept on existing wastewater treatment plants and to test and confirm the system design on different water flows and environmental conditions.

The pilot system was installed at 10 different water treatment plants and the results will be published later this year, the company says.
