Case Brief: Sodium Hypochlorite Electrolysis Cell Review

Project background

A disinfection project required on-site chlorine generation, but the initial enquiry did not yet distinguish between an electrolysis cell, an electrode package, a sodium hypochlorite unit or a wider EPC-integrated system.

Key technical questions

• Is the process based on seawater electro-chlorination, diluted brine electrolysis or a sodium hypochlorite generation unit?
• What effective chlorine output, flow rate, feed-water quality, chloride concentration and operating hours are required?
• What power, cooling, cleaning, scaling-control and installation interface should be considered?
• Which part of the project should TJNE supply: electrodes, cell unit, equipment module or defined skid/container cooperation?

TJNE review logic

TJNE reviews chlorine-based disinfection projects from the electrochemical core outward: electrode material, cell structure, operating current, flow condition, maintenance plan and integration interface should be aligned before quotation.

TJNE supply scope

• MMO titanium anodes and electrode assemblies for chlorine evolution.
• Electrolysis cell units and sodium hypochlorite / electro-chlorination equipment modules.
• Technical datasheets, drawings and interface information for integration.
• Balance-of-plant, civil works, site operation and full EPC scope should be defined separately with the project party.

Project outcome

The project can be classified into the correct supply scope early, helping the technical team avoid unclear quotations and confirm the information needed for a fit-for-purpose electrolysis configuration.
