Explore our heavy-duty industrial ozone generators, membrane filtration systems, and architectural water feature components precision-built for UK municipal pools, leisure centers, and luxury spas.
Achieving regulatory compliance, reducing operating expenses, and guaranteeing air/water purity with advanced Corona Discharge (CD) Ozone Oxidation Systems.
In the contemporary UK leisure and hospitality sector, commercial pool operators face a double bind: rising energy and chemical costs paired with rigorous regulatory expectations set by the Pool Water Treatment Advisory Group (PWTAG) and BS EN 15288 Standards. Traditional rely-on-chlorine-alone sanitization protocols are proving increasingly inadequate for high-bather-load environments such as municipal leisure centers, hotel wellness hydro-spas, and competition pools. Heavy chlorine dosing leads to the accumulation of volatile disinfection-by-products (DBPs)—specifically volatile mono-, di-, and tri-chloramines—which cause unpleasant eye irritation, offensive indoor hall odors, respiratory discomfort for bathers and staff, and aggressive atmospheric corrosion of metallic pool hall superstructures.
As an ISO 9001:2008 certified manufacturer and global exporter of advanced aquatic engineering equipment, our company supplies specialized Commercial Ozone Generators (O3) explicitly tailored to the UK market. Ozone is the undisputed gold standard in secondary oxidation. Operating as a microscopic powerful oxidant (potentiometric redox potential of +2.07V compared to chlorine's +1.36V), dissolved ozone instantaneously destroys organic contaminants, inactivates chlorine-resistant pathogens like Cryptosporidium parvum and Giardia lamblia in milliseconds, and oxidizes chloramines back into harmless nitrogen gas and free chloride ions. By incorporating our high-concentration vacuum- or pressure-feed ozone systems into your filtration loop, UK facilities routinely reduce free chlorine reliance by up to 60–80%, eliminate off-gassing indoors, and dramatically lower backwash replacement water heating demands.
Designed for continuous 24/7 commercial duty cycles with high-frequency micro-gap dielectric cells and automated PLC process control.
Our core ozone reaction chambers feature precision-machined, high-purity quartz dielectric tubes with titanium or 316L stainless steel outer electrodes. Micro-gap design optimizes heat dissipation and maximizes electrical efficiency.
Effective ozone creation demands ultradry feed gas. Our skid-mounted ozone systems integrate automated Pressure Swing Adsorption (PSA) oxygen concentrators and dew-point dried air feed units (< -60°C PDP).
Strictly compliant with UK Health and Safety Executive (HSE) HSG179 guidelines. Fully automated monitoring ensures immediate shutdown in the event of ambient gas detection or flow loss.

Customizing hydraulic integration to meet the specific physical and operational demands of UK leisure infrastructure.
Municipal facilities managed by UK trusts (such as GLL/Better, Everyone Active, or Places Leisure) experience immense peak bather density during weekend family sessions and swimming lessons. Standard chlorine dosing fails to suppress combined chlorine spikes, resulting in bathers complaining of eye burns and staff reporting respiratory fatigue.
Our Solution: Full-flow or slipstream ozone skid systems operating with a minimum 2-minute hydraulic reaction tank contact time, followed by granular activated carbon (GAC) residual ozone destruct filters. This keeps combined chlorine strictly below the PWTAG maximum limit of 0.2 mg/L, even under maximum load conditions.
Hydrotherapy pools in NHS medical centers and commercial luxury spas (e.g., in Bath, London, or the Cotswolds) operate at elevated water temperatures (34°C to 38°C). Elevated temperatures accelerate bather skin shedding, sweat production, and microbial multiplication, creating an ideal environment for Pseudomonas aeruginosa.
Our Solution: High-concentration ozone generators paired with inline ORP and residual ozone controllers. Ozone rapidly oxidizes organic body oils and inactivates thermal-tolerant bacteria without triggering high chlorine off-gassing that ruins the luxurious ambience of premium indoor spa sanctuaries.
Large-volume aquatic centers require crystal-clear water with minimal light turbidity to ensure uninterrupted visibility for underwater camera timing systems and lifeguards. Water clarity is directly tied to micro-flocculation.
Our Solution: Ozone acts as a natural micro-flocculant. By converting organic dissolved solids into larger agglomerated particles, our systems enhance sand filter retention efficiency down to sub-micron levels, delivering breathtaking visual clarity across 50-meter visual sightlines while drastically reducing filter backwashing frequencies.
UK outdoor lidos face unique challenges from organic debris, direct sunlight, rain runoff, and seasonal usage surges during summer heatwaves. Maintaining consistent water chemistry under variable weather conditions can overwhelm basic chemical controllers.
Our Solution: Weatherproof IP65-rated skid packaging with automated variable-output ozone generation (10% to 100% modulation) tied to real-time bather count and water temperature sensors, guaranteeing stable oxidation without over-chlorinating during cooler low-traffic days.
Aligning pool water oxidation with the UK Leisure Sector's drive toward Net-Zero Carbon emissions and reduced utility expenditures.
With UK commercial gas and electricity prices fluctuating significantly over recent seasons, leisure operators can no longer afford to dump thousands of liters of heated pool water daily simply to dilute high Total Dissolved Solids (TDS) and cyanuric acid/chloramine concentrations. Traditional guidelines suggested replacing 30 liters of fresh water per bather per day. Because fresh tap water in the UK must be heated from an average ground temperature of 8°C to 28°C–30°C, water replacement represents one of the largest gas boiler energy sinks in a leisure building.
How Aura Ozone Systems Reduce Carbon Footprints:
Over two decades of specialized manufacturing experience, ISO 9001 certified quality controls, and full OEM export capabilities.
For more than 20 years, our engineering enterprise has designed, fabricated, and commissioned complete aquatic solutions. With over 1,500 successfully delivered global installations, our expertise encompasses both heavy commercial ozone/filtration systems and architectural water features.
Every commercial ozone generator, power supply unit, stainless steel contact vessel, and PLC automation cabinet undergoes 100% factory acceptance testing (FAT) prior to crating. Pressure testing, electrical high-potential insulation testing, and O3 yield calibration are documented for every build.
We provide complete international freight compliance, including ISPM-15 wooden crating, custom voltage/frequency manufacturing (230V 1-Phase / 400V 3-Phase 50Hz for the UK grid), step-by-step CAD installation schematics, and remote commissioning support for UK M&E contractors.
Direct technical responses to common engineering, compliance, and retrofitting questions.
Our commercial ozone generator skids are installed on a slipstream (side-stream) loop off the main filtration return pipework. Water is drawn after the media filters, passes through a high-efficiency Venturi injector where vacuum draws ozone into the water stream, enters a dedicated steel contact tank for a minimum 2-minute reaction period, and then passes through a Granular Activated Carbon (GAC) de-ozonation bed to remove residual ozone before returning to the main line prior to final residual chlorine/pH dosing. This side-stream installation allows easy retrofitting into existing UK plant rooms without requiring major pipework reconstruction.
No. According to PWTAG guidelines and UK public health safety codes, a tiny persistent free chlorine residual (typically 0.5 mg/L to 1.0 mg/L, down from 2.0–3.0 mg/L) must be maintained in the main pool tank to provide secondary protection against bather-to-bather cross-contamination in stagnant zones. Ozone acts as the primary oxidizer and disinfectant in the plant room loop, destroying 99.9% of organics and pathogens, allowing the pool tank chlorine dose to be kept at absolute minimum baseline levels without chloramine formation.
All our UK-bound export units are built specifically for the UK electrical grid standard: 230V Single-Phase or 400V Three-Phase AC at 50Hz. Power electronics feature high-frequency IGBT inverter technology to minimize energy consumption, with power factor correction (>0.95). Control panels feature CE compliance with emergency stop buttons, flow interlocks, and digital Modbus/BACnet communications for seamless connection to Building Management Systems (BMS).
While medium-pressure UV systems alter the DNA of Cryptosporidium oocysts to prevent replication, high-concentration ozone oxidizes and ruptures the outer protective shell of the oocyst directly, achieving physical destruction (inactivation) within a short contact time. Furthermore, unlike UV systems which suffer efficiency loss when quartz sleeves become fouled by hard water calcium scale (common in Southern and Eastern UK water supplies), ozone injection efficiency is completely independent of water clarity or sleeve scaling.
Routine maintenance is straightforward: periodic inspection of feed-gas air dryer desiccant/filters, annually checking the venturi suction check valve, cleaning or replacing oxygen concentrator intake filters, and inspecting ambient ozone safety sensor calibration every 12 months. Dielectric quartz tubes feature long service lives and typically require visual inspection once a year. We supply complete 1-year and 3-year spare parts kits with every UK export order.
Yes. Our systems are engineered in strict alignment with UK Health and Safety Executive HSG179 ("Managing Health and Safety in Swimming Pools") and PWTAG Code of Practice requirements. This includes dual-stage ambient O3 room monitors, automatic fail-safe shutoff valves, vacuum safety operation (preventing ozone leaks under positive pressure), and catalytic off-gas destruction units on contact tank air relief valves.
Due to substantial savings on backwash water heating energy (gas/electricity), reduced liquid chlorine/calcium hypochlorite purchasing, lower chemical air duct ventilation replacement costs, and extended pool hall asset life (preventing structural rust), most commercial UK leisure facilities achieve full capital cost recovery (ROI) within 18 to 30 months of continuous operation.
