Widespread contamination from pharmaceuticals, such as synthetic or natural chemicals found in prescription medicines, over-the-counter therapeutic drugs & veterinary drugs, that are finding their way into the drinking water supply via wastewater, is posing serious threats to public health. Pharmaceutical compounds such as hormones and endocrine disrupters are already responsible for major health issues. Their presence in water, even at low concentrations, has raised concerns in the EU among drinking water regulators, governments, water suppliers & the public regarding these pharmaceutical contaminants’ risks both to human health and the environment.
The challenge is that current wastewater treatment methods do not degrade many of such pharmaceutical contaminants, and may even generate more toxic by-products. Modern wastewater treatment facilities (WWTFs) are built for collection, transportation and purification of wastewater. In this Phase 2 project the PFS technology has been demonstrated at three separate wastewater treatment plants.
Firstly, Pharem believes that the best way forward is to make technologies and combination of technologies available so that more WWTPs can start focusing on treatment of OMPs. However, to be able to do so, the existing barriers such as high CapEx costs, unsafe operations and high OpEx costs must be addressed.
In the project, Pharem has proven that enzymatic treatment can offer a unique alternative to established technologies.
Following the project objectives, the results have confirmed that Pharem can offer a treatment step which:
• Low CapEx, lowering the entry barrier for any WWTP
• Adjust removal level according to customer specification (70%-90%)
• Offer OpEx between 0,05-0,10 €/m3 (depending on site specific requirements)
• Simple application by plug-and-play or using familiar sand-filtration infrastructure
• Add no new hazard requirements and possibility to full-service solutions
With PFS we have aspired to deliver a solution that is easy to implement and do not require large budgets to both initiate and operate. The ambition is to make it easier for small to medium sized WWTPs to take the step to implement removal of pharmaceutical residues and organic micropollutants. The only way to solve the environmental issue is to achieve a broad market application of these types of technologies.
