ASCANDRA

Ascandra, developed by Eden Tech, is a deep‑tech microfluidic prefiltration system designed for municipal and industrial water reuse. Its biomimetic architecture inspired by lung hydrodynamics and manta‑ray particle capture forms a controlled, massively integrated microscale network that increases particle capture efficiency while reducing maintenance and water loss. Ascandra directs microparticles through engineered laminar flow channels carved into stacked microfluidic discs, concentrating pollutants into dedicated collection zones. That predictable accumulation enables short, highly efficient targeted backwash cycles, removing the usual trade‑off between high filtration performance and intensive backwash or chemical cleaning regimes. The system runs at low hydraulic head loss (~0.85 bar) and very low energy consumption (4–20 Wh/m³), delivering hydraulic yields above 99% and minimal water loss (typically 0.1-5%, vs 5-20% for conventional prefilters). By stabilizing feedwater quality upstream, Ascandra protects downstream membrane processes such as nanofiltration (NF) and reverse osmosis (RO), significantly reducing fouling rates, cleaning frequency, chemical consumption, and associated downtime- the main contributors to operating expenditure in reuse facilities. Industrial pilots on real wastewater reported autonomous operation, reliable pressure recovery, approximately 40% energy savings, and up to 80% reduction in plant downtime. Offered in a modular, compact, plug‑and‑play format, Ascandra scales from 200 to 25,000 m³/day and emphasizes ease of usability and operability. It is targeted at membrane‑intensive installations and applications where conventional prefiltration constrains performance or raises costs. By providing a compact, low‑energy, high‑yield prefiltration stage, Ascandra strengthens water resilience for reuse projects and helps address emerging contaminants, including microplastics, while lowering total lifecycle costs and environmental impact.
