A growing healthcare challenge
Healthcare is essential to our health and quality of life. Yet it also has a big environmental footprint. Wastewater pollution is one of them. Residues from medicines and diagnostic agents reach rivers and drinking water sources, as municipal wastewater treatment plants are not designed to remove them.
- Medicines and contrast media leave the body, often quickly and via urine.
- Removal is hardly possible and needs more energy and cost.
- Rules are getting stricter. New proven interventions for better water quality are essential.

Protect water
Remove residues before they spread.
- Capture at the source
- Reduce downstream load
- Support safer water
Solutions for every hospital department
Zereau systems capture medical residues where concentrations are highest, inside hospital departments. Start where your challenge is most urgent, then expand as needs and regulations evolve.

Impact at the source
Zereau systems deliver measurable impact. That spans environment and operations.
Up to 99.99% removal
Removal at the source, before dilution. State claims for non-saturated filters.
~70% less water to treat
Less water means less energy use. It also lowers running costs.
Recovery-ready streams
Concentrated residues keep recovery realistic. Policy still defines routes.
Less downstream strain
Catch residues inside the hospital fence. Ease load on city utilities.

What hospitals say:
“The Netherlands scores poorly on surface water quality. Noordwest Ziekenhuisgroep acts by installing Zereau filters in multiple departments. They capture pharmaceuticals and antibiotics at the source, reduce strain on water authorities, and improve regional water quality.”
