Titanium Anodes for Water Treatment Matched to the Water You Actually Run
Every water treatment titanium electrode we make starts from your water analysis, current window and cell drawing – not from a catalogue name. You receive an electrolysis electrode specified for the reaction you need, so what passes your pilot keeps performing in the units you ship.

Defined Treatment or Disinfection Objective
A measurable target – residual chlorine, COD reduction or recovery – agreed before sampling starts.
What Should Your Water Treatment Electrode Achieve?
Pick the treatment objective first. It tells our engineers which reaction to favour, which data to request and which risks to check – so your quotation is built on the right questions from the first email.
Same Application Name, Different Electrode
“Pool” or “wastewater” alone cannot define a coating. Your water and operating window decide it.
Objective 01
Generate an Active Species
On-site hypochlorite, mixed oxidants or another active species produced inside your cell. A coating matched to brine strength and current density keeps output steady after commissioning instead of drifting within months.
Questions we will ask you
- What salt or brine concentration feeds the cell?
- What output rate and concentration do you need per hour?
- Does the cell run continuously or in batches?
Objective 02
Disinfect Water or Equipment
Electrolytic disinfection for pools, process water or rinse lines. Specifying for low-salinity water up front prevents under-dosing and the voltage climb that usually follows.
Questions we will ask you
- What chloride level and conductivity does the water carry?
- What free-chlorine residual must you hold?
- Do you reverse polarity to control scaling?
Objective 03
Remove or Reduce a Target Component
Electro-oxidation duty to cut COD, ammonia, colour or a specific pollutant. Knowing the target early steers you away from coatings that waste current on side reactions and inflate power cost.
Questions we will ask you
- Which component, and what start and target concentration?
- What suspended solids and oils reach the electrode?
- How will removal be measured and accepted?
Objective 04
Transform a Contaminant Electrochemically
Converting a compound into a less harmful or easier-to-separate form. We align the coating direction with the reaction pathway, so the result from your lab cell can be reproduced in a scaled cell.
Questions we will ask you
- Which compound, and what product do you want?
- What pH and temperature window applies?
- Do you already have lab or literature results?
Objective 05
Recover a Material or Resource
Recovering metals or reusable chemicals from process or rinse water. An anode chosen for oxygen-evolution load and acid content protects both recovered-product purity and your cathode deposit.
Questions we will ask you
- Which metal or material, and at what concentration?
- What acid and sulfate content is in the electrolyte?
- What deposit quality does your buyer require?

Ask an Engineer to Classify ItHow a Titanium Electrode for Water Treatment Really Performs
An MMO titanium anode never works alone. Its result depends on six linked conditions, and we review all six together – that is how a custom electrolysis electrode becomes a predictable part of your system rather than a recurring service call.
Titanium Anode & Coating Direction
Pure titanium substrate with Ru-Ir, Ir-Ta or platinum coatings selected for chlorine or oxygen evolution, so the active layer serves the reaction you are paying for.
Cathode or Matching Electrode
Titanium, stainless steel or a second coated anode for polarity reversal. Matching both sides stops one electrode from limiting the life of the whole cell.
Water or Electrolyte Chemistry
Chloride, sulfate, pH, hardness and organics change which reaction wins at the surface. Your water analysis keeps the coating choice grounded in facts.
Anode · Cathode · Water · Power · Geometry · Result
Current, Voltage, Temperature & Duty Cycle
Current density and on/off cycling drive coating consumption. Real operating windows let us size active area for the service life you expect.
Cell Geometry, Flow & Connections
Plate, mesh, tube or rod forms, electrode gap and conductor design shape current distribution. We machine and weld to your drawing so parts drop straight into your cell.
Target Result & Validation
Output, removal rate or residual chlorine defined with a test method, so every sample is judged pass or fail on data – not on opinion.
Want these six conditions reviewed against your own cell?
Send Your Operating DataYour Water Analysis Shapes the Electrode Before Any Drawing Does
We read every parameter for what it does to reaction selectivity, scaling, flow and coating wear. The result is an electrode specification built for the water your system will really see – not an idealised test solution.
Chloride
Sets how readily chlorine forms at the anode and decides between chlorine- and oxygen-evolution coatings.
Hardness & Alkalinity
Calcium and carbonate scale the cathode, push voltage up and block flow paths. Tells us whether to plan polarity reversal or acid cleaning.
pH
Shifts reaction pathways and coating stability, especially in acidic recovery streams or alkaline wastewater.
Temperature
Warmer water lowers cell voltage but can accelerate coating wear. We factor it into your current-density limit.
Dissolved Solids & Conductivity
Determines the voltage, and therefore the power cost, for your target current. Low-conductivity water may need tighter gaps.
Suspended Solids
Particles abrade coatings and lodge in mesh openings. Guides mesh size, spacing and pre-filtration advice.
Organics & Oils
Consume oxidant and foul surfaces. Lets us estimate a realistic output and a cleaning interval you can plan around.
Target Contaminant
The compound you must remove or convert. Defines which reaction to favour and how the result will be validated.

Turn your water analysis into a clear electrode recommendation.
Upload Your Water AnalysisRoute the Reaction First, Then Choose the Coating
Chlorine evolution, oxygen evolution and other electrochemical routes call for different anode chemistry. Routing your project before quoting avoids the most common – and most expensive – mismatch in water treatment electrodes.
Electrolyte & Target Reaction
What is in the water, and what must happen at the anode surface?
Chlorine-Evolution Discussion
For chloride-bearing water where you want hypochlorite or mixed oxidants. Usually discussed with Ru-Ir based MMO coatings, which favour chlorine generation at lower cell voltage.
Typical fit
- Sodium hypochlorite generators
- Pool and spa salt chlorinators
- Seawater or brine electrochlorination
Oxygen-Evolution Discussion
For sulfate-rich or acidic electrolytes where oxygen forms at the anode. Usually discussed with Ir-Ta coatings, which are built to withstand this harsher duty.
Typical fit
- Metal recovery from rinse water
- Acidic process streams
- Oxidation in low-chloride water
Other Electrochemical Direction
When the target is a specific contaminant, a combined route or a process not yet characterised. We propose bench or pilot tests before you commit to a coating.
Typical fit
- Organic or ammonia oxidation
- Combined disinfection and removal
- New process development
Coating Direction for Technical Review
Every route ends in a written coating direction listing the assumptions behind it, reviewed by your engineers before any sample is made.
A coating direction is a starting point, not a performance guarantee. Final selection depends on your verified water data, operating window and pilot results.
Unsure which route your water belongs to?

Electrode & Coating Direction
Coating family and loading matched to current density and target life, documented for your engineers to approve.
Geometry, Spacing & Flow
Plate, mesh or tube form and electrode gap set for even current and clear flow, so gas and solids leave the cell.
Power, Connections & Monitoring
Terminal type, conductor size and sealing matched to your rectifier and housing to prevent hot spots at the joint.
Validation, Cleaning & Replacement
Test method, cleaning routine and replacement criteria agreed early, so your field service follows a plan.
Drawing & Repeat Supply
A controlled drawing and part number lock the design, so your 50th order matches the sample you approved.

Start Your System ReviewWhere Our Water Treatment Titanium Electrodes Work
Each site changes the water, output, power, space and maintenance conditions your electrode must handle. Select an area to see what shifts – and how we adjust the electrode so it fits that duty instead of a generic one.
Municipal Drinking Water
Electrodes sized for round-the-clock duty and seasonal hardness hold a stable residual without oversizing the cell or the rectifier.
Industrial Process & Cooling Water
Hard, warm and recirculating water scales quickly. Electrode spacing and polarity strategy chosen for that load keep voltage – and your energy bill – under control.
Swimming Pool & Spa Disinfection
Low-salt pools and warm spas punish the wrong coating. Cells specified for your salt level and reversal cycle stay effective season after season, reducing warranty returns.
Food & Beverage Hygiene Water
Rinse and wash-water disinfection needs consistent dosing near product lines. Clean-design cells and documented materials make your hygiene audits easier.
Industrial Wastewater Treatment
Variable COD, solids and oils change by the hour. Robust geometry and a coating route chosen for your effluent keep removal stable when the feed is not.
Pilot & Laboratory Testing
Small electrodes built to production specification give you test data you can scale. Samples start from 1–10 pieces, so you validate before you invest.
Replacement Electrodes for Existing Cells
Send the worn part or its drawing. We reproduce fit and connections, review why it wore out, and propose a coating that lasts longer in the same housing.

As a titanium electrode manufacturer in Foshan, we run every step in-house and attach a quality check to each one. That is why the part you approve as a sample is the part you receive in volume.
Titanium Substrate
Check: commercially pure plate, mesh, rod or tube verified against the material certificate before cutting.
Cutting & Machining
Check: laser cutting, punching and CNC work to your drawing, with first-piece dimensions confirmed.
Welding & Conductor Joints
Check: titanium tabs and rods welded under shielding; each joint inspected for fusion and alignment.
Surface Preparation
Check: blasting and acid etching build the clean, rough surface the coating needs to anchor.
Coating & Thermal Curing
Check: repeated coat-and-bake cycles with coating loading tracked per batch for repeatable output.
Dimensional Check
Check: key dimensions, flatness and hole positions measured against the current drawing revision.
Coating & Function Inspection
Check: visual coating review and electrical checks, with retained samples kept from each batch.
Part Marking & Identity
Check: part number and batch ID marked on the part or tag, so any field part traces back to its records.
Protective Packaging
Check: coated faces separated and fixed in export crates to arrive without scratches or bent tabs.
SampleBuilt on the same nine steps, with its route recorded against the drawing revision.
BatchRepeats that recorded route, so production parts match the sample you signed off.

Talk to the Foshan Project TeamAnswers Engineers Ask About Titanium Anodes for Water Treatment
Choose a topic and open a question. Each answer comes from day-to-day work as a titanium electrode manufacturer – practical guidance you can apply to your MMO titanium anode or electrolysis electrode project today.
Water & Electrolyte Data
Good data is the cheapest way to avoid a wrong electrode. Learn what to measure and how to share it.
Read related articlesWhich water parameters do you need before quoting?
Chloride, hardness, alkalinity, pH, temperature, conductivity or TDS, suspended solids, organics and your target compound. A recent lab report is ideal; partial data plus a description of the water source is enough to start.
Can you work from a synthetic test solution?
Yes, for early screening. The final coating direction should be confirmed on real site water, because trace components can shift reaction selectivity and fouling behaviour.
How do you handle seasonal changes in water quality?
Share the worst-case values – highest hardness, lowest temperature, lowest salinity. We size the electrode for the whole range, not only the average, so performance holds all year.
Chlorine vs Oxygen Evolution
The reaction at the anode decides the coating family. Get this right and most other choices follow.
See MMO titanium anodesHow do I know if my process is chlorine- or oxygen-evolution?
Chloride level, pH and the product you want decide it. With chloride present and hypochlorite as the goal, chlorine evolution dominates. In sulfate or acidic media with little chloride, oxygen evolution does.
What happens if the wrong coating family is used?
Usually higher voltage, lower output and faster coating loss. It is the most frequent root cause we find when customers ask us to replace electrodes from another source.
Can one electrode handle both reactions?
Some mixed duties exist. We assess them case by case and normally recommend a short bench test before you commit to a production coating.
Titanium Substrate & MMO Coatings
Substrate form and coating chemistry together set life, cost and fit. Compare the options here.
See platinized titanium anodesWhich titanium do you use for the substrate?
Commercially pure titanium in plate, mesh, rod, tube or wire form, chosen for your geometry. Material certificates are available on request.
What is the difference between Ru-Ir, Ir-Ta and platinized coatings?
Ru-Ir MMO favours chlorine evolution; Ir-Ta suits oxygen evolution and acidic media; platinized titanium is used where a platinum surface is preferred. We select by your operating conditions, not by habit.
Can worn titanium electrodes be recoated?
Often yes, if the substrate is not pitted or deformed. Recoating can lower your replacement cost; we assess photos or the returned part first.
Current Density, Spacing & Connections
How current reaches and spreads over the electrode decides both efficiency and life.
See electrolytic cellsWhy does current density matter so much?
It sets how fast the coating is consumed. Running above design density shortens life even with the right coating, so we size active area from your real operating current.
How close should the anode and cathode be?
Narrow gaps lower voltage but raise the risk of scaling and blockage. We balance the gap against your water's hardness, solids and flow rate.
What connection types can you make?
Welded titanium tabs, threaded rods, bolted terminals and custom conductor designs, all built to your housing and current requirement.
Installation, Cleaning & Maintenance
Correct handling and cleaning protect the coating you paid for and keep output stable.
Read maintenance guidesHow should coated electrodes be handled during installation?
Hold them by edges or tabs, keep tools off the coated surface and keep insulation spacers in place. Scratches expose titanium and create weak spots.
How do I remove scale safely?
Use a dilute acid clean suited to your deposit for a limited time, then rinse well. Avoid scraping the coating. We provide guidance for your specific deposit type.
When should an electrode be replaced?
When cleaning no longer restores output at normal voltage, or titanium is visibly exposed across the active area. Logging voltage trends makes this predictable.
Common Causes of Premature Problems
Most early failures repeat the same few patterns. Recognise them before they reach your customers.
See custom titanium electrodesWhat causes most early electrode failures?
A coating that does not match the reaction, current density above design, scaling without a cleaning plan, and weak connections that overheat locally.
Does polarity reversal damage MMO anodes?
It can if the coating is not specified for it or the reversal is too frequent. Tell us your reversal cycle and we specify the electrode for it.
How do you investigate a failed electrode?
Send photos, operating logs and, if possible, the part. We review the surface, joints and data, then give you a written finding with corrective options.
