Why Choose ASSEMA Biorotors?
Engineered for Sustainable Water Treatment
Our A-Line RBC units are designed to achieve the best treatment results through high-end quality specifications. We prioritize long life expectancy and safe maintenance for every wastewater project, ensuring a reliable solution for capacities up to 3000 IE.
Superior Material Selection
Built with full stainless steel shafts and high-quality PP panels to withstand corrosive environments and ensure maximum durability.
Advanced Operational Safety
Every unit features loss-of-rotation detection, alarm lights, and soft starters to guarantee safe function and protect your equipment.
Flexible Installation Options
Choose between fully pre-assembled, transportable PP housings for fast setup or customized components for local concrete integration.
Low-Maintenance Automation
Designed for comfortable long-term use with integrated automatic greasing systems, reducing the need for manual intervention and site visits.

ENGINEERING EXCELLENCE
Flexible Housing & Installation Options
The ASSEMA A-Line series is available with or without housing. If you choose a unit without housing (to be built in concrete locally), our technicians provide specific technical drawings and requirements to ensure a perfect fit on-site.
For a faster setup, our fully equipped PP housing units come pre-assembled and transportable. These units are easy to handle and feature integrated in-and-outlet systems, guaranteeing a seamless and rapid installation process.
SOLUTIONS FOR INDUSTRIAL WASTEWATER TREATMENT
High-Efficiency Ecological Biorotors
Engineered to withstand heavy organic and hydraulic fluctuations, ASSEMA RBC units deliver sustainable, low-maintenance secondary treatment. Our advanced biological contactors optimize oxygen transfer at a microscopic level, creating a resilient ecosystem that guarantees stable effluent quality for municipal and industrial applications.
Dynamic Load Adaptation
ASSEMA systems feature intelligent variable frequency drives that automatically adjust rotational speed based on real-time biological oxygen demand (BOD) sensor data, ensuring precise treatment without energy waste.
Engineered Bio-Film Matrix
The PP panels are custom-textured on a micro-scale to maximize surface area for robust biofilm attachment, while the full stainless steel shaft incorporates advanced torsion monitoring for predictive maintenance of high-torque loads.
Proactive Process Diagnostics
Beyond automatic greasing, our units feature vibration analysis and loss-of-rotation detection that integrate directly with SCADA systems for predictive diagnostics, preventing process upsets.
