최근 의약품 잔류물의 제거를 위한 Mobile pilot ozone 시스템을 구축하기 위해 , Primozone을 스웨덴 오존 발전 공급자에게 제공했다.

이 프로젝트는 기존의 폐수 처리 시설에 대한 개념뿐만 아니라, 테스트를 증명하는 다른 물 흐름과 환경 조건에 대한 시스템 설계를 확인하는 목적으로, Tillväxtverket, 경제 및 지역 성장을 위한 스웨덴의 기관에 의해 투자되었다.

이 프로젝트는 기존의 폐수 처리 공장이 의약품 잔류 물을 제거하기 위해 장착되지 않은 점을 감안하여 진행된다.

Funding has recently been provided to Primozone, a Swedish ozone generator supplier, to build a mobile pilot scale ozone system for the removal of pharmaceutical residue.

The project has been funded by Tillväxtverket, the Swedish agency for economical and regional growth, with the goal of proving the concept on existing wastewater treatment plants, as well as testing and confirming the system design on different water flows and environmental conditions.

This endeavor is underway given that existing wastewater treatment plants are not equipped to remove pharmaceutical residue.

The presence of pharmaceutical residue in wastewater has been a prevalent issue for more than a decade, and numerous studies have been conducted to determine its influence on the environment.

As such, many countries in Europe are taking necessary political action to reduce its effects despite the advent of the technology. One example is taking place in Switzerland, where a political decision will equip about 100 sewage plants with the residue-removing systems.

Pharmaceutical residue is also often difficult to break down, as it is stable by nature. Ozone, however, is an effective solution because it serves as a selective oxidant that primarily attacks electron-rich structures in molecules, such as double bonds. Ozone is also the most sustainable technology both in terms of economy and environmental friendliness.

"Removal of pharmaceutical residue with ozone can be done at a surprisingly low cost per m3 water treated," said Anders Schening, CEO of Primozone. "Unlike other technologies, ozone treatment leaves no residue or byproducts that need further treatment -- ozone is produced by oxygen and will revert to oxygen again after it has reacted."
