Envirolyte on-site water disinfection systems generate anolyte close to the point of use for controlled treatment of municipal drinking water, commercial water systems, process water and selected industrial applications. The technology can be integrated into both new and existing treatment installations where continuous or demand-based disinfection is required.
A typical Envirolyte water disinfection system combines one or more anolyte generators with brine preparation, solution storage, dosing equipment and process controls. Dosing can be linked to water flow, free available chlorine (FAC), oxidation-reduction potential (ORP) or another validated control strategy selected for the source water and treatment objective.
System capacity, anolyte concentration, target residual and monitoring requirements must be evaluated for each project. Learn more about electrochemical activation technology, compare the ELA, ANW and HD anolyte generator ranges, and review the available approvals and compliance information.
Water Disinfection Applications
Envirolyte systems can be evaluated for water treatment projects across municipal, commercial, food-processing, hospitality, recreational and maritime environments.
- Municipal drinking water and residential distribution systems
- Rural and decentralised drinking water supplies
- Breweries, beverage plants and food-production facilities
- Dairies and other process-water installations
- Hotels, restaurants, hospitals and schools
- Swimming pools and recreational water systems
- Golf-course and landscape water systems
- Ships, offshore facilities and other maritime installations
How an Envirolyte Water Disinfection System Works
Filtered or conditioned water and sodium chloride brine are supplied to the Envirolyte generator. The electrochemical cell produces an oxidising anolyte solution, which is transferred to a storage tank and metered into the water line by a dosing pump. A flow meter or FAC/ORP control loop can be used to adjust dosing according to operating conditions.
Core System Components
- One or more Envirolyte anolyte generators selected for the required output and operating regime
- Water filtration, pressure regulation or softening where required by source-water quality
- Brine preparation or sodium chloride solution storage
- Anolyte storage tank with suitable level controls
- Dosing pump or pumps selected for the required injection rate and pressure
- Flow, FAC, ORP or other project-specific monitoring and control equipment
- Injection point, sampling points and integration with the existing water-treatment process
Dosing and Residual Control
The required dosing rate depends on water flow, temperature, pH, organic load, turbidity, microbial challenge, contact time and the required residual at the monitoring point. A commissioning programme should establish operating setpoints and confirm performance through appropriate chemical and microbiological testing.
Anolyte for Water Disinfection
Anolyte is the oxidising solution generated in the anodic chamber of an electrochemical cell. Depending on generator configuration, pH and operating conditions, the free available chlorine fraction can include hypochlorous acid and hypochlorite species. The relative distribution of these species and their performance are influenced by solution pH and the characteristics of the treated water.
Across different Envirolyte system families, equipment-level operating ranges may extend from approximately pH 2.0 to 8.5 and from about 100 to 6,000 mg/L of active chlorine. These figures do not apply to every generator and must not be confused with the required residual concentration in finished drinking water.
Operational Benefits of On-Site Generation
- Generation of active solution close to the point of use
- Reduced dependence on delivery and storage of concentrated disinfectant products
- Automated production and controlled metering into the water line
- Integration with flow, FAC or ORP monitoring
- Scalable configurations for small, medium and high-capacity installations
- Potential support for microbial, algae and biofilm control when the complete treatment programme is correctly designed and validated
- Project-specific integration with tanks, pumps, filters, controllers and remote monitoring
Performance data should be interpreted in relation to the applicable test conditions and the specific water-treatment application. Supporting materials are available in the sections covering microbiological testing, disinfection by-products testing and ECHA and BPR information.
Comparison with Conventional Water Disinfection Methods
The manufacturer comparison chart below provides a general overview. It should not be interpreted as a universal performance guarantee because the suitability of chlorine gas, hypochlorite, chloramination, chlorine dioxide, anolyte and other treatment methods depends on source water, required residual, contact time, by-product limits, site safety and regulatory requirements. See the detailed water disinfectant comparison for additional context.

The following manufacturer comparison provides a general overview of selected operational characteristics of gas chlorine, delivered hypochlorite, calcium hypochlorite, chloramination, chlorine dioxide and on-site generated anolyte. Actual performance depends on source-water quality, treatment objectives, system design, operating conditions and applicable regulations.

- Source-water pH, temperature, turbidity and organic load
- Microbiological challenge and treatment objective
- Required contact time and target residual
- Available water pressure, power supply and installation space
- Required generator redundancy and storage capacity
- FAC, ORP, flow or other monitoring requirements
- Pre-treatment, dosing-pump and injection-point requirements
- Applicable drinking-water, biocidal and workplace-safety regulations
- Commissioning, sampling and ongoing verification procedures
Frequently Asked Questions
Most Envirolyte water disinfection configurations use water, sodium chloride and electricity. Additional filtration, softening, pressure control or brine preparation may be required depending on the generator and source-water quality.
The appropriate control method depends on the application, water chemistry and regulatory requirements. FAC provides a direct measurement of free available chlorine, while ORP can support process control under validated and stable operating conditions. Some projects also use flow-proportional dosing with residual verification.
No. Generator output, solution pH, active chlorine concentration, dosing rate, contact time and residual targets vary by product configuration and project. Current product documentation and project-specific validation should always be used.
