Disinfection without chemicals

What does the equipment solve?

  • Reduces bacterial/viral load, discolors dissolved organic matter.
  • Ozonation of air in premises and sanitary areas (mode with MPC sensors).
  • Works in conjunction with a skimmer - accelerates flocculation and foam collection.
  • Residual O₃/ORP control, soft thresholds to protect fish and personnel.

Equipment

  • Corona discharge generator with modular reactors and VFD cooling fan.
  • O₂ source: PSA concentrator (93±3%) or LOX connection; drying to ≤−40…−60 °C tdew.
  • Dosing: Venturi injectors/ejectors, mixing tubes or static mixers.
  • Contact column with calculated contact time (CT) and drift eliminator.
  • Degasser and ozone destroyer (catalytic/activated carbon).
  • Sensors: residual O₃ (water), O₃ (air), ORP, flow; emergency ventilation.
  • Control panel with event log, interlocks and remote access.

How it works and how safe it is

Principle

Ozone is generated from oxygen, supplied to water through an injector/mixer and contacted in the column. The exhaust gas undergoes degassing and mandatory destruction on the destructor. Level control - by CT (concentration × time) and residue control.

  • CT landmark: 0.1–0.5 mg min/l in the circulation tract.
  • Residue in water: target <0.05–0.10 mg/L in front of fish pools.
  • ORP window: +300…+380 mV in the contact zone (individually by type/salinity).
Security and interlocking
  • Two levels of O₃ sensors in the air (warning/alarm), automatic activation of the hood.
  • Interlocks: no water flow → stop O₃ supply; no vacuum on venturi → generator stop.
  • Destructor with resource indicator; column bypass for service.
  • Water circuit materials - PVDF/PVC-U/stainless. AISI 316L; EPDM/PTFE in seals.
  • “Night sanitization” mode with a delay in putting into circulation until the balance is reset to zero.

Options and selection

  • Generator power: PSA O₂ (economical and autonomous) or LOX (maximum performance); The air feed requires deep drying.
  • Feeding scheme: inline injector, contact tower, or skimmer + ozone unit for quick polishing and surfactant removal.
  • Selection according to technical specifications: flow rate m³/h, target effect (QMAFAnM/color/turbidity), temperatures, salinity, residual O₃ limits.
  • Energy: 8–14 kW at 200–500 g/h (guideline, depends on O₂ feed and cooler).

Options and integration

  • Cascade of O₃ sensors (water/air) with verification and calibration.
  • Automatic regeneration/replacement of destructor adsorbent.
  • SCADA: ORP/O₃/consumption trends, reports and remote notifications.
  • Version for sea water, IP54–IP65, outdoor enclosures with heating.
