Purgatoria makes the transition to TRL 9: Two new Icabus sieving systems for wastewater treatment in the Netherlands and Scotland

This year Purgatoria makes the important step from TRL 7 (tested) to TRL 8 (demonstrated) and even TRL 9 (commercial phase). We have been given the opportunity to develop two new Icabus screening systems for wastewater processing in two projects: one in the Netherlands (Asten) and one in Scotland (Alloa).

Successful milestones in 2024
2024 was a particularly successful year for Purgatoria. We completed a six-month test phase at the WWTP Zeist and welcomed Jacco Tijssen to our team. Jacco completed his studies in HTS Mechanical Engineering, HTS Industrial Engineering and Erasmus Business Administration and is a valuable addition to our organization. In addition, we have further optimized the ICABUS after two years of successful use at various locations.

Processing capacity: The ICABUS can process more than 500 m³/hour per system, including DWA, RWA and first flush. The peak capacity has not yet been definitively determined.

Dry matter yield: The dry matter yield is around 30% net, which means that this percentage is calculated on the basis of the load in the influent compared to the dewatered mass. This also applies to start and stop operation.

Ease of maintenance: The ICABUS does not require intensive maintenance. There is no need for a busy operator to check, adjust or clean, and there is no need for hot soap flushes.

Pressure drop: The pressure drop across the sieve is only 10 cm water column, so no additional pumping phase is required.
