Sea Water Anolyte Generators for Maritime and Offshore Disinfection

Envirolyte sea water anolyte generators are on-site electrochemical systems designed to produce ANK-neutral anolyte directly from seawater or brackish water. The technology uses the natural sodium chloride content of sea water as the feed source, reducing the need for mains water and prepared brine in selected coastal, maritime and aquaculture applications.

Sea water anolyte generation is suitable where operators need compact disinfectant production near the point of use: ships, offshore facilities, coastal installations, swimming pools using sea water, fish and shrimp farming, hatcheries and process water treatment. The generated anolyte provides active chlorine for water disinfection, sanitation and microbial control while simplifying logistics and chemical handling.

Envirolyte sea water units are designed to generate ANK-neutral anolyte and, if required, catholyte from feed water with salinity from 5–7 PSU for brackish water up to 33–35 PSU for ocean water. The active chlorine concentration is typically configured in the range of 500–1000 ppm, depending on model, feed water and project requirements.

New Opportunities for Seawater-Based Anolyte Production

The use of seawater as feed brine for Envirolyte generators creates new opportunities for disinfection, sterilisation and water purification where access to mains water or prepared brine is limited. Since seawater is predominantly a sodium chloride solution with additional dissolved salts, it can provide sufficient chloride content for the electrochemical generation of active chlorine in the final anolyte solution.

This approach extends Envirolyte technology into maritime, offshore, coastal and aquaculture applications where seawater is readily available. It is especially relevant for on-board water hygiene, seawater swimming pools, fish farming, shrimp farming, hatchery water treatment and coastal process water disinfection.

How Envirolyte Sea Water Generators Work

Envirolyte sea water machines are a further development of Envirolyte electrochemical activation technology. Instead of preparing a separate salt brine, the system uses seawater or brackish water as the main feed source. For background on the process, see electrochemical activation technology, diaphragmatic cells and electrolysed water solutions.
