Probiotic Commercial Water Treatment — Legionella Control for Cooling Towers & HVAC

Sanitify probiotic water treatment eliminates Legionella-supporting biofilm in cooling towers, HVAC circuits, and industrial water systems — reducing Legionella risk and chemical dosing costs without biocide resistance or residue concerns.

Why Facilities Managers Use Probiotic Water Treatment

  • Sanitify probiotic treatment eliminates the biofilm in which Legionella pneumophila colonises in cooling towers and HVAC circuits
  • Bacillus bacteria digest sludge and biofilm — reducing Legionella risk between scheduled chemical disinfection cycles
  • No biocide resistance — biological treatment complements chemical programmes without creating resistance pressure

Sanitify is most effective as a complementary treatment — most systems reduce biocide use by 50–70%.
Yes — document in your Written Scheme as part of a comprehensive Legionella risk management programme.
Compatible with most oxidising and non-oxidising biocides. Apply Sanitify 48–72 hours after high-dose shock treatments.
Sanitify maintains or improves efficiency by reducing biofilm — even a 1mm layer increases heat exchange resistance by 10–20%.
Typically below 1,000 CFU/L (EU action level) within 4–6 weeks. For very high counts, a chemical shock dose before starting Sanitify is recommended.

Dose the System — Biological Treatment Runs Continuously

Add Sanitify to the cooling tower basin or HVAC balancing tank at 5ml per 1,000L. Bacillus bacteria distribute through all pipework and heat exchangers within 4–6 hours. Re-dose every 3–4 weeks as part of a scheduled water treatment programme.

What our customers are saying?

Sanitify Probiotic Pool Cleaner has completely changed our pool care. We don’t miss the chemical smells or the irritation – the water is always clean and clear. Best decision we made for our pool!” – Liina

We wanted a natural alternative to chlorine for our pool, and Sanitify was the perfect solution. Not only does it keep the pool spotless, but I feel better knowing there are no harmful chemicals around my kids. The water smells fresh, and we couldn’t be happier!” – James
Anne
My kids have sensitive skin, so using chemicals in the pool was always a concern. With Sanitify, there’s no irritation, no red eyes, and the water feels so much softer. I can’t recommend it enough for families!

Eliminate Legionella Biofilm Without Harsh Biocides

Legionella requires biofilm to colonise and multiply. Standard chemical disinfection reduces counts but does not eliminate the biofilm substrate — it re-establishes within days. Sanitify targets this root cause: Bacillus bacteria continuously digest the biofilm Legionella requires. Independent studies show >99% Legionella reduction in Sanitify-treated cooling tower systems within 4 weeks.

Commercial cooling towers use 10–25kg of biocide chemicals per year. Sanitify reduces biocide consumption by 50–70% by managing organic load and biofilm between treatment cycles — reducing procurement costs, hazard handling requirements, and chemical storage obligations.

Bacillus Technology in Commercial Water Systems

Sanitify Water Treatment contains Bacillus subtilis, Bacillus licheniformis, and Bacillus amyloliquefaciens — strains selected for industrial water treatment efficacy. These bacteria produce biosurfactants that penetrate and disrupt biofilm matrix from within — eliminating the Legionella habitat and exposing biofilm-protected bacteria to natural antimicrobial conditions.
