Descaling effectiveness…4 months after BacComber treatmentThe cooling water pipe as shown by the arrow heat was cut off tofacilitate the addition of a new cooling tower. The cooling tower was treated by chemical for the past 6 years and was changed to BacComber treatment 4 months prior to the addition of the new cooling tower.
The photos shows the various section of the pipe cut off from the cooling tower. It can be seen in the photos that the scale and chemical deposists in the pipeline are descale off from the pipe wall. The formation of magnetite is also clearly seen forming onthe pipe wall.
There is also a swction of the pipe showing the thick chemical deposits are cracking and spalling off from the pipe wall.

Condenser End Box condition 8 months after BacCombertreatment
This condenser was open up in Feb 2003 for inspection, 8 months after the BacCombertreatment.
The photos were taken immediately after the end cover was open. The condition of the end box shown in the photos was before washing.
The photos clearly show that the condenser was in excellent condition and there were no sign of scaling and corrosion problem after treatment by BacCombersystem.

How BacComber control bacteria growth
• Using Copper-Silver ionization to kill the bacteria directly.
• Using electromagnetic treatment to indirectly kill and control bacteria growth.
