Why it works

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

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.

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.

What customers are saying

Our facility runs several water systems that used to need constant chemical dosing. Sanitify has meaningfully reduced our maintenance calls.
Peeter M.
Legionella risk management is a serious part of our job. Sanitify's probiotic approach gives us another tool to keep our systems cleaner between full disinfection cycles.
Karin L.
Simple to dose, and our plumbing team has noticed less scale buildup across the building's water lines.

Frequently asked questions

Can Sanitify replace biocides in our cooling tower programme?
Sanitify is most effective as a complementary treatment — most systems reduce biocide use by 50–70%.
Does Sanitify meet HSE L8 Legionella guidance?
Yes — document in your Written Scheme as part of a comprehensive Legionella risk management programme.
Is Sanitify compatible with isothiazolinone or DBNPA biocides?
Compatible with most oxidising and non-oxidising biocides. Apply Sanitify 48–72 hours after high-dose shock treatments.
Does Sanitify affect heat exchanger efficiency?
Sanitify maintains or improves efficiency by reducing biofilm — even a 1mm layer increases heat exchange resistance by 10–20%.
How quickly does Sanitify reduce Legionella counts?
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.
Can Sanitify be used in a closed-loop HVAC circuit?
Yes — dose at 2ml per 1,000L, re-dose every 6 weeks. The biological community self-maintains with minimal re-dosing.
What monitoring should I do alongside Sanitify?
Continue standard Legionella monitoring. Also monitor BOD and total viable counts (TVC) as Sanitify performance indicators.
Does Sanitify affect corrosion inhibitor programmes?
Compatible with phosphonate, molybdate, and azole-based corrosion inhibitors. Does not consume or inactivate these compounds.
Is Sanitify safe in cooling tower blowdown water?
Yes — non-toxic to aquatic life at blowdown concentrations. No special treatment required prior to discharge.
Can Sanitify be used in decorative water features?
Yes — use 5ml per 1,000L, re-dose every 3–4 weeks for biofilm, algae, and Legionella control.
What is included in a commercial treatment consultation?
System assessment, volume calculation, dosing protocol design, compatibility check, and Legionella Written Scheme documentation support.
Does Sanitify require approval for use in drinking water systems?
Not approved for direct dosing into mains drinking water. Suitable for cooling towers, HVAC, decorative features, and non-potable water systems.
Does Sanitify work in fire suppression water storage tanks?
Yes — use 2ml per 1,000L annually to maintain water quality in stagnant fire suppression storage systems.
Can Sanitify reduce our chemical procurement costs?
Yes — commercial facilities report 40–60% reduction in biocide procurement. Annual savings for large cooling tower systems typically exceed €5,000.
Where can I order Sanitify for a commercial facility?
Available in 100ml and 5L formats. Commercial accounts with scheduled delivery available — contact our commercial team for volume pricing.
