Our Modular Ceramic Treatment Unit
A Fusion of Ceramic Membrane Technology & Upfront Coagulation to Enhance Performance
What is a Modular Ceramic Treatment Unit (m-CTU®₃₇)?
Developed to meet rising demand for quality, efficiency and sustainability, our m-CTU®₃₇ product is a modular solution for scaling water treatment performance. It also addresses some of the most complex challenges in modern water treatment.
Designed for plants processing up to 500 ML/day, it uses a ceramic ultrafiltration module with plug-and-play capabilities to deliver industry-leading water purification.
Key features include:
- Busbars, which reduce the time required for on-site electrical assembly by including cabling within the unit.
- Single Motor Control Centre (MCC) and remote IO/CPU, allowing for standardised software and commissioning.
- CeraMac® C37 membrane vessel housing 37 individual ceramic membranes across a compact filtration area of 925m2. First-class microfiltration is monitored through daily pressure decay tests.
- Membrane feed pump, which can operate across a flow range of 92 – 227m3/hr – making it highly adaptable from project to project.
- ILCA® (Inline Coagulation and Adsorption) vessel, designed to form micro-floc, which enhances membrane filtration performance due to reduced traditional flocculation time.
- Backwash vessel, enabling high-pressure backwash cycles that effectively clean the membranes, extending their operational life and maintaining performance.
- m-POA™ (Point-of-Application Dosing), providing dosing for chemically-enhanced backwashing of the membranes and ensuring thorough maintenance.
- Standard product instrument boards, ensuring consistent quality monitoring to maintain safe and reliable membrane operation throughout the unit’s lifecycle.
Reimagining Water Treatment Across the UK and Beyond
In 2025, we were awarded the King’s Award for Innovation in recognition of the development of the m-CTU®₃₇. Some of the reasons our customers also approve of this product include:
- Low-carbon and recycled materials significantly reduce the environmental impact
- Thanks to advanced fabrication techniques and its modular design, we’ve achieved up to 50% faster project timelines
- Modularisation ensures first-class quality control and safety standards
- Minimal upfront design requirements are needed, which streamlines the overall process
- Modular units connect seamlessly, allowing effortless scalability and integration with our other products
”The m-CTU®₃₇ is more than a technological breakthrough. It embodies our vision and commitment to building a more sustainable, scalable and resilient future of water treatment.
Stephen SlessorRSE Chief Executive Officer
The King's Award for Enterprise in Innovation is a tremendous honour and a reflection of the creativity and determination of our team. Our modular m-CTU®₃₇ is not just a product, it’s the future of water treatment.
