BCP™ 1015 - Legionella Control Program - Case Study

A Major Commercial complex with 5,500 RT HVAC system using BCP™ 1015 (Classic DTEA II™ ) for:

1. Legionella Bacteria Control Program (BCP™ )
2. Biofilm Control Program (BCP™ )
3. Cleaner/Penetrant Aid/Dispersant

Cooling System Before Application of BCP™ 1015 (Classic DTEA II™ )

Cooling System After Application of BCP 1015 (Classic DTEA II)

Legionella Bacteria levels Before BCP (Biofilm Control Program)

Legionella Bacteria levels Before BCP (Biofilm Control Program)

Conclusion

• Chemical treatment program before application of BCP 1015 (Classic DTEA II) was not effective in controlling Legionella bacteria in this cooling water system.
• Application of BCP 1015 (Classic DTEA II) on a monthly dosage at 70 ppm (product based) and dosing with oxidizing biocide ( 100 ppm product) effectively controlled Legionella bacteria in this cooling water system.
