Solution Selection Guide
Start with the Contaminant and Treatment Target
Electrode selection should follow a characterized water stream and a measurable treatment objective. Define contaminants, COD or TOC where relevant, chloride, conductivity, pH, temperature, flow, target removal, byproduct constraints, electrical duty and reactor geometry before comparing MMO, Ir-Ta, PbO₂ or BDD paths.
Before Requesting a Quote
Confirm whether you need an electrode, a custom reactor-electrode assembly, a replacement component or a treatability and pilot-evaluation path. Include representative water analysis, the analytical treatment target, hydraulic and electrical conditions, reactor drawing and byproduct limits. Complete treatment performance should be discussed only against an agreed test and system boundary.
Process Review
Build the Specification in the Right Order
A reliable electrochemical water-treatment specification begins with representative water analysis and a measurable treatment target, then defines the hydraulic and electrical reactor duty, compatible electrode paths, analytical test method and validation boundary.
Define the Target
State removal, oxidation, disinfection or separation objective and the acceptance metric.
Establish Reactor Duty
Provide flow, batch or continuous mode, retention time, current density, voltage and geometry.
Select a Validation Path
Define bench, pilot or replacement basis, analytical method, byproduct concern and documentation.
Solution Configurations
Match the Supply Path to the Operating Conditions
Use the confirmed process conditions to compare material, coating, geometry, assembly and documentation requirements. Final configuration remains project-specific.
Solution Route
MMO / Ir-Ta Electrode Review
For defined oxygen-evolution, oxidation or related electrochemical duties compatible with the actual water chemistry.
Start with
Water analysis, target reaction, chloride, current density, temperature, geometry and acceptance metric.
Solution Route
PbO₂ Electrode Review
For selected advanced-oxidation duties requiring separate substrate, chemistry and validation review.
Start with
Contaminant, electrolyte, PbO₂ structure, current load, handling, test method and acceptance.
Solution Route
BDD Electrode Review
For selected difficult-to-treat streams where a BDD path is evaluated through treatability and commercial review.
Start with
Complete water analysis, contaminant load, target, conductivity, flow, test basis and reactor interface.
Solution Route
Custom Reactor Electrode Assemblies
For drawing-based electrodes or replacement assemblies integrated into a defined reactor boundary.
Start with
Reactor drawing, dimensions, spacing, connection, flow, pressure, materials and maintenance access.
Technical Intake
Inputs Required Before Product Selection
Provide the inputs that materially affect chemistry, geometry, qualification and commercial scope. Unknown values can be marked for joint review.
Water Analysis
Source, contaminant concentrations, COD or TOC, chloride, conductivity, pH, hardness and temperature.
Treatment Target
Required removal, oxidation, disinfection or separation result and analytical acceptance method.
Hydraulic Duty
Flow, batch or continuous mode, retention time, pressure, mixing and mass-transfer conditions.
Electrical Duty
Current, current density, voltage, electrode area, spacing, polarity and operating cycle.
Reactor Boundary
Tank or cell geometry, materials, ports, connection, cleaning, gas handling and maintenance.
Validation
Bench or pilot plan, sampling, byproducts, energy basis, electrode inspection and documentation.
Supply Scope & Qualification
Define Responsibilities Before Quotation
MMO, Ir-Ta, PbO₂ and BDD electrodes have different electrochemical behavior, construction, validation needs and commercial implications. A water-treatment result cannot be promised from the electrode name alone. Treatability, byproducts, energy use, reactor design and operating control must be evaluated for the actual stream.
Electrodes & Treatment Applications
Electrochemical Water Treatment Configurations
Review representative electrode technologies, reactor arrangements and treatment applications. Water analysis, treatment target, hydraulic duty and validation plan determine the technical route.

Questions Before an RFQ
Can the electrode be selected from COD alone?
No. Contaminant identity, chloride, conductivity, pH, temperature, flow, target, reactor and byproduct constraints also affect the technical path.
Are MMO, PbO₂ and BDD interchangeable?
No. They have different reaction behavior, materials, operating windows, evidence requirements and costs.
When is a pilot test appropriate?
A pilot is useful when the stream is variable, contaminants are complex, byproducts matter or scale-up cannot be supported reliably by existing data.
Does HELE guarantee the complete treatment result?
Not from an electrode quotation alone. Any performance commitment must be tied to an agreed water analysis, reactor, operating window, test method and supply boundary.
