Why schools choose ClearFox®
Built for the academic calendar
Fixed-bed biology and automatic power-saving control handle concentrated term-time loads and long holiday shutdowns without losing performance — the single hardest thing about school wastewater.
Safe, compact, and unobtrusive
Compact and underground-capable installation preserves site space and keeps the plant away from student areas; low-odour operation keeps the learning environment undisturbed.
Virtually no maintenance
Long-life components, no moving parts inside the tank, and automatic operation mean industry-leading low lifecycle costs — ideal for schools with limited technical staff and tight budgets.
Modular and expandable
Add capacity in step with growing enrolment or new buildings, without replacing the system.
Guaranteed compliance
We give a process guarantee that your system will meet the required discharge values.

The technology we supply
Every ClearFox school system is assembled from proven, in-house process modules — so you get the exact treatment chain your site needs, and nothing you don’t:
- Mechanical Screening — removes coarse solids at the front end.
- Fixed Bed Biofilm Reactor (FBBR) — the ideal school technology: fixed biofilm naturally rides out load swings and extended no-flow periods, runs automatically with minimal operator input, and enters power-saving mode when no flow is detected, restarting the moment flow returns.
- Sequencing Batch Reactor (SBR) — acts as an equalisation basin, tolerating peak flows during school hours and low flows off-period.
- ClearFox® Nature (non-electric) — a robust, power-free option for small or remote schools.
- Containerized Systems — the whole treatment chain, factory-tested and ready to connect, with underground options for minimal visual impact and preserved play space.
