Drain Water Disinfection Unit

Filtration and UV disinfection sized so recirculation never becomes a disease route.

A pre-filtration and UV disinfection skid that makes full drain water recirculation safe, with dose validated against measured transmission rather than assumed.

  • Dose controlled against live UV transmission measurement
  • Automatic backflush pre-filtration down to 20 µm
  • Validated 99.99 % reduction of Pythium and Fusarium
  • Buffer management integrated with the fertigation unit
  • Lamp hours and sleeve fouling tracked and alarmed

Indicative lead time: 8 - 10 weeks

Recirculation without the risk

Reusing drain water is the single largest water and fertiliser saving available to a substrate grower, and the single fastest way to distribute a root pathogen through an entire site. Treatment is not optional; it is the thing that makes the saving safe.

Dose against measured transmission

UV dose depends on how much light actually passes through the water, and drain water transmission changes with organic load. The disinfection unit measures transmission in line and modulates lamp output to hold the target dose, instead of assuming a clean-water figure that stops being true in week three of the crop.

Sized to the peak, not the average

Disinfection capacity is calculated against your peak irrigation hour on the longest day. A unit sized to daily average will silently bypass untreated water exactly when the crop is most vulnerable.
