The challenge
Growing therapy demand is putting pressure on existing infrastructure.
Nuclear medicine is growing rapidly, more therapies, more patients, new radionuclides. But existing wastewater systems are designed or not suitable to handle this at scale. Decay tanks require space, investment and long processing times, while increasing volumes strain capacity and limit growth. As regulatory pressure rises, hospitals are forced to rethink how radioactive wastewater is managed — without compromising care delivery.
Limited tank capacity
Existing infrastructure struggles to keep up with increasing patient volumes.
Space & cost constraints
Expanding tank systems requires significant investment and physical space.
Inefficient downstream handling
Dilution and storage do not solve contamination at the source.
The Zereau approach
Filtering at the source instead of managing downstream.
Zereau systems capture radioactive contaminants directly at the point of origin — the patient’s toilet.
This approach integrates seamlessly into existing workflows, without requiring major infrastructure changes.
By filtering radionuclides at the source, hospitals can avoid, reduce or postpone the need for additional decay tank capacity. This relieves pressure on existing wastewater infrastructure, increases operational flexibility and creates immediate room for therapy growth.
System configurations
Flexible system setups tailored to different clinical environments and infrastructure constraints.
RadiCatch Toilet all-in-one Filter System
Where patients receive radionuclide therapies, excretions contain high concentrations of radioactive contaminants. This system filters wastewater directly at the source, preventing contamination from entering the hospital infrastructure.
- Installed in patient bathrooms or shared therapy lounges.
- No need for decay tanks.
- No construction work needed.
- All-in-one vacuum toilet filter solution to capture all patient's excretion and remove 99.99% or more of the radionuclides.
Complete plug-and-play solution for installation in patient rooms or shared therapy lounges to kick-start therapy.
RadiCatch Urine FilterBOX
Focus on urine separation and radionuclide filtration at the source: either as an add-on to existing decay tanks to increase effective capacity, or as a stand-alone approach in regulatory frameworks where radioactive wastewater management can focus specifically on urine.
- Installed in patient bathrooms or shared therapy lounges.
- Connects to existing drainage systems.
- Reduces load on central decay tank infrastructure.
Simple solution to create space in existing decay tank capacity or to kick-start therapy
RadiCatch Hybrid
Combination of toilet filter solution and compact decay tanks. Centralized or decentralized filtration. Scalable for multiple rooms.
- Designed for high-capacity environments
- Supports centralized filtration setups.
- Scales with growing therapy demand, still compact due to filtration first - storage next principle.
- Water storage allows collection of wastewater from showers and sinks.
Suitable for large departments and multi-room setups

What hospitals say:
“The Zereau RadiCatch FilterBOX is installed in one of our therapy rooms and connected to our decay tanks. By filtering the excretions of high-dose I-131 patients, we freed enough tank capacity to expand our therapy program — increasing treatments from 700 to 900 per year.”
