What is Tersano Stabilized Aqueous Ozone (SAO) in Singapore?

Tersano Stabilized Aqueous Ozone (SAO) is a game-changing cleaning technology that uses only tap water and oxygen to create a powerful, natural disinfectant. Unlike traditional chemicals, SAO contains no toxins, VOCs, artificial scents, or residues. It kills up to 99.999% of germs—including E. coli, MRSA, Salmonella, viruses like COVID-19, and more—in seconds, then reverts safely back to plain water and oxygen.
​
The patented LotusPro V9 wall-mounted dispenser generates SAO on-demand directly from your cold tap water. No mixing, no storing hazardous bottles, no chemical allergies. ProMedUSA, as Singapore’s leading Tersano partner with 8+ years of local installations, helps businesses replace over 90% of their cleaning chemicals while meeting strict HACCP, Green Mark, and ESG standards.

Why Singapore Businesses Are Switching to Tersano SAO

Singapore’s hot, humid climate accelerates mould, mildew, germ growth and chemical degradation. Tersano SAO offers fast, residue-free sanitation perfect for high-traffic areas like hospitals, hotels, offices, and food courts. With rising costs, ESG pressures and sustainability goals, switching to SAO reduces labour costs, plastic waste, water usage, and chemical dumping—delivering real ROI.

How the Tersano LotusPro V9 Creates SAO from Tap Water

The LotusPro V9 plumbs directly into your cold water line. Water flows through a patented SAO cartridge using electrolytic technology to add stabilized ozone (O₃). The result: ready-to-use SAO (Stabilised Aqueous Ozonated Water) at up to 11.5 liters per minute.

The Step-by-Step Process

  1. Tap water enters the dispenser.
  2. It passes through filters and the SAO cartridge.
  3. Patented stabilization extends ozone life (disinfectant up to 24 hours, cleaner up to 6 days).
  4. Dispense powerful SAO into spray bottles, buckets, or scrubbers—no dilution required.
Cartridge life: SAO4 is 3,000 liters; SAO24 is 5,000 liters. The free of charge Tersano IoT WiFi dashboard lets you monitor usage remotely on any computer or device.

Frequently Asked Questions – Tersano Singapore

How much does Tersano cost in Singapore?

Can it replace all my cleaners?

Yes – over 90% in most cases (glass, floors, stainless steel, etc.).

Will Tersano hurt my skin or cause it to crack like chemicals do?

Actually, you'll find that when you switch to Tersano, your hands become softer. Cracks and rashes disappear because Tersano is not allergic and as safe as plain tap water. 

Do I need to use gloves or protective eyewear when mixing Tersano?

Absolutely not! No protective gear, gloves, or eyewear is needed when prepared.  And, you don't need to mix it. You simply press a button on the LotusPro V9, and the ozonated water is generated on demand as you need it. 

When I'm finished cleaning, can I just pour the used Tersano down the drain? Will it pollute Singapore's water table or ecosystem?

Yes, you can simply pour the used Tersano down the drain, as it simply will turn back to plain normal tap water. It is non-polluting, but sustainable and ESG compliant.
