Generate ozone on-site for powerful oxidation of colour compounds, refractory organics, pathogens, and micropollutants without chemical storage risks.
Ozonation uses ozone (O3), one of the strongest oxidants (E° = 2.07 V), to destroy colour compounds, break down refractory organics, disinfect pathogens, and remove odours. Ozone is generated on-site from air or oxygen via corona discharge, eliminating the need for chemical delivery and storage. It reacts directly with unsaturated bonds (C=C) and indirectly via hydroxyl radicals. Ozonation is particularly effective for textile dyes, pharmaceutical residues, and taste/odour compounds.
Ozone generated from air/oxygen on demand – no chemical storage, transport, or handling risks.
Ozone selectively attacks chromophore groups, destroying colour from dyes without full mineralisation.
More effective than chlorine against viruses, Giardia, and Cryptosporidium. No disinfection byproducts.
Residual ozone decomposes to oxygen in minutes. No harmful byproducts in effluent.
Step-by-step breakdown of the treatment process from influent to effluent.
Ambient air dried to dewpoint -60°C or PSA oxygen concentrated to 90-95% O2. Feed gas quality determines ozone concentration.
High-voltage (5-20 kV) silent discharge across dielectric gap converts O2 to O3. Typical output 5-15 wt% ozone in oxygen.
Ozone bubbled through water in counter-current contact column or venturi injector. Contact time 10-30 minutes. Redox potential monitored.
Ozone attacks organics directly (ozonolysis of C=C bonds) and indirectly via OH → radicals. Colour reduced, COD lowered, pathogens inactivated.
Excess ozone destroyed by catalytic destructor or thermal decomposition. Off-gas treated to prevent atmospheric release.

This treatment stage is engineered to achieve specific contaminant removal targets while providing stable, predictable performance across variable inlet conditions. Design parameters are calculated from wastewater characterisation data, regulatory requirements, and site-specific constraints including footprint, energy availability, and operator capability.
Design validated by CFD modelling and pilot testing to confirm performance guarantees.
Equipment selected for 20-year design life with minimal wearing parts and easy access.
Automated dosing and feedback control minimise reagent consumption and sludge production.
Online monitoring and data logging demonstrate continuous consent compliance.

No treatment stage operates in isolation. This process is designed to receive conditioned influent from upstream stages and deliver effluent quality suitable for downstream processes. Hydraulic and organic loading rates are balanced across the complete treatment train to prevent bottlenecking and ensure overall plant efficiency. Our engineers model the complete flowsheet to optimise Capital expenditure and Operating expenditure across the plant lifecycle.
Screening, equalisation, and pre-treatment protect this stage from damage and overload.
Effluent quality ensures downstream biology, filtration, or disinfection performs optimally.
Reject streams, filtrate, and centrate are routed back to appropriate upstream points.
Our engineers design and commission complete treatment systems including all equipment, automation, and commissioning support.
Our expertise spans multiple industries with sector-specific water treatment solutions.
