Sodium Hypochlorite Generation

Custom Titanium Anodes for Sodium Hypochlorite Generators

We build MMO titanium anodes, matching cathodes and electrolysis electrode assemblies around your feed brine, available-chlorine target, current density, voltage, temperature, flow, duty cycle and cell geometry. You receive a titanium electrode that fits your electrolyzer and its real operating window, with an engineering review before you commit to a sample.

On-Site Generation Process

From Brine to Sodium Hypochlorite: Four Stages That Shape Your Electrode

Every stage of on-site sodium hypochlorite generation changes what a titanium anode for electrochlorination has to withstand. Answering four questions up front gives you a quotation built on your process, fewer sample rounds, and an electrochlorination electrode sized for the duty it will actually see.

Salt crystals used to prepare brine for electrolysis STAGE 01

Water and Salt Preparation

What water source, salt type, brine concentration, filtration and pre-treatment will enter the electrolyzer?

Feed quality drives deposits and coating wear. Defining it first protects electrode life and keeps cleaning intervals predictable.

Water test strip being compared for chlorine, pH and hardness STAGE 02

Brine Condition Review

What chloride concentration, pH, temperature, hardness, impurities and normal operating range must be considered?

A known operating range lets us choose a coating direction with margin, instead of one tuned only for ideal conditions.

Electrodes running electrolysis of salt water STAGE 03

Electrolysis Cell and Electrodes

What current density, total current, voltage, active area, spacing, flow and connection arrangement will the cell use?

Matching active area and spacing to your rectifier keeps cell voltage and power use where your design expects them.

Chlorine level test kit used to check product solution STAGE 04

Product Solution and System Control

What available-chlorine output, solution concentration, operating cycle, monitoring method and acceptance test are required?

An agreed acceptance test means the sample is judged against your target output, not a generic catalogue claim.

An electrode cannot be selected from size alone. We review your complete process data before confirming the coating, geometry and cell interfaces, so you are not paying for a second sample round to correct a guess.

Share your brine and output targets, and we will propose the coating direction, geometry and interfaces for your review.

Inside the Electrolyzer

Inside a Sodium Hypochlorite Electrolyzer

Your output depends on more than the anode alone. The cathode, spacing, current distribution, brine flow, temperature, gas handling and power supply all shape the result, so we design each sodium hypochlorite generator titanium anode as part of your cell rather than as a loose part.

BRINE IN PRODUCTOUTLET GAS OUT ANODE CATHODE SPACING 1 2 3 4

In a sodium hypochlorite generator, the coated titanium electrode supports the chlorine-evolution reaction. Under controlled system conditions, the active chlorine formed is converted into the hypochlorite solution your system doses. The four points below are where a well-matched electrode protects your output, your power budget and your maintenance schedule.

  1. 1

    Application-Matched Titanium Anode

    The coating direction and titanium form are evaluated against your brine chemistry, intended reaction, current load, temperature and operating cycle, so the anode suits the service interval you plan for.

  2. 2

    Matching Cathode and Electrode Pair

    Cathode material, geometry, polarity, spacing and assembly relationship are confirmed with the anode, so the pair installs as one set and you source both from one supplier.

  3. 3

    Active Area and Current Connections

    Dimensions, active area, holes, tabs, welding, busbar interfaces, current-feeding points and supports follow your equipment drawing. Even current feeding helps avoid local hot spots and uneven coating wear.

  4. 4

    Cell Flow and Maintenance Access

    Electrode count, spacing, inlet and outlet positions, flow direction, gas outlet, cleaning, disassembly and replacement access are defined before production, which shortens service work later.

The same outside dimensions do not guarantee the same electrochemical fit. Brine, reaction, electrical load, flow and validation conditions must be reviewed together.

Replacing an existing anode? Send photos of the old electrode and your cell drawing, and we will check the fit before quoting.

Field Risk Alarm Log

Recognize the Alarm Before It Becomes a Field Failure

Most field complaints about a sodium hypochlorite generator appear as one of six alarms, and each one points to specific data. Reviewing that data with our engineers before you reorder shows whether the electrode, the brine or the cell needs to change, so your budget goes to the real fix.

Custom Electrode Assembly

Build the Electrode Assembly Around the Electrolyzer

Instead of adapting your cell to a standard part, we build the custom electrolyzer electrode assembly around your equipment. Each custom MMO titanium anode, cathode, frame and connection is defined from your drawing or sample, so the assembly drops into place and your service team can replace it without modification.

01

Coated Titanium Anode

Plate, mesh, expanded mesh, rod, tube or fabricated forms, developed around the active area and reaction you need.

02

Matching Cathode

Material, form, area, spacing, polarity and replacement relationship confirmed with the anode, so both parts are ordered as one set.

03

Current Connections

Welded tabs, conductor bars, busbar interfaces, current-feeding points, cable clearances and polarity marks that prevent wiring mistakes.

Frequently Asked Questions

Technical Resources for Sodium Hypochlorite Generator Builders

Short answers to the questions engineers and buyers ask most while specifying an MMO titanium anode for on-site generation. Use them to prepare your data, then ask us for a review of your own project.

Laboratory flasks holding test solutions

Terms used on this page

The same words mean the same thing in our quotations, drawings and inspection records, which keeps both teams aligned.

  • MMO titanium anode
  • Mixed metal oxide anodes
  • Electrolysis electrode
  • Chlorine evolution
  • Current density
  • Active area
  • Available chlorine
  • Electrode spacing

Link the coating direction to the brine, target reaction, current load, temperature and cell design. Mixed metal oxide anodes for chlorine evolution are chosen differently from those for oxygen evolution, so the brine and operating window need to be known first. Sharing these early helps you avoid a sample that works in a short lab test but wears quickly in service.

Current density, total current, active area, electrode count and current-feeding design should be reviewed together. For the same total current, a larger active area lowers current density, which changes the load on the coating and the cell voltage. Reviewing them together lets us size the electrode to your rectifier instead of asking you to change the power supply.

Chloride concentration, hardness, pH, temperature, filtration, known impurities and the brine-preparation method. These values reveal deposit and contamination risks that can shorten electrode life, and they let us point out pre-treatment needs before you invest in samples.

Spacing, brine conductivity, deposits, geometry, connections and current distribution all influence electrical behavior. A narrower gap can lower voltage but may raise gas-release and flow concerns, while deposits and poor connections push voltage up. Reviewing these points together helps keep your power consumption predictable.

Confirm the deposit type, the cleaning method and chemicals, and how the coated surface will be supported and protected while it is handled. Coated surfaces can be damaged by scratching or unsuitable cleaning, so an agreed procedure protects the electrode you have invested in.

Check brine concentration, electrical data, flow, temperature, deposits, polarity, connections, cleaning practice and operating history before concluding that the electrode is worn. Many declines have process causes, so working through this checklist helps you avoid replacing parts that are still serviceable.
