Task:
To evaluate specific scavenger resins for PFAS removal, a pilot plant was required—with complex series interconnection and solids management.
Solution:
On-site trials with a flexibly deployable rental pilot plant from MionTec. The configuration enabled fluidized-bed operation and solids separation between stages.
Result/Benefit:
The piloting delivered reliable data under real-world conditions and helped to specifically validate the subsequent full-scale plant concept.
Challenge:
A research facility in Norway required a highly automated laboratory system for ion exchange processes – with flexibly adjustable process conditions.
Solution:
Following tests with a rental system, MionTec designed a laboratory system with three columns at 1-liter scale. Co-current and counter-current processes are possible in various operating modes – including comprehensive measurement technology.
Result/Benefit:
The system enables automated, reproducible tests with high reliability – an ideal foundation for further pilot-scale studies.
Task:
A fermented process solution contained organic salts as by-products that hindered further processing.
Solution:
A two-stage ion exchange process was developed: first, the removal of hardness minerals, then the conversion of the salts into organic acids.
Result/Benefit:
The purified broth can now be further processed economically – the material stream was upgraded and disruptive by-products were specifically eliminated.
Objective:
A direct performance comparison of various ion exchange resins was intended to show whether alternative manufacturers can keep pace with established brands—without quality risks.
Solution:
The resins were tested under identical conditions in a realistic series configuration and analyzed for various performance parameters.
Result/Benefit:
The tests revealed clear differences in performance and stability. MionTec was then able to provide well-founded recommendations for practical use in deionized water (DI) systems.
Task:
On eight existing demineralization lines, continuous optimization of regenerant consumption was to be implemented – instead of sporadic readjustments.
Solution:
MionTec gradually installed the MiVision.SensIQ system in multiple generations. Specific metrological challenges were resolved, and the software was continuously developed.
Result/Benefit:
Regenerant quantities could initially be optimized manually and later semi-automatically. Result: Savings of over 45% while maintaining consistent water quality.
Challenge:
In the condensate system of a dairy, the organic content needed to be measured quickly and with high resolution. The existing instrumentation was too slow and too imprecise, leading to unnecessary waste, cleaning effort, and costs.
Solution:
MionTec developed a proprietary measurement method that surpassed conventional online instruments in both measurement speed and sensitivity. Erroneous measurements typical of standard delta-conductivity TOC systems were systematically eliminated.
Result/Benefit:
A patent-pending, universally applicable TOC analyzer was created. Initial field tests are already underway at the customer site – with measurements up to 15 times faster and sensitivity more than 100 times better than previous solutions.
Task:
The entire deionized water production facility was to be redesigned over a period of up to 10 years, under constrained structural conditions and with the demolition of an existing building.
Solution:
MionTec facilitated a three-day workshop with all stakeholders to generate ideas, developed several solution scenarios, and translated them into a detailed basic engineering package including mass balances, cost comparisons, and automation concepts.
Result/benefit:
The deliverable is used as a technical appendix for the tender. The project was implemented in close coordination with SWM’s project management—providing a clear, robust concept for the coming years.
