1. What it is?
Electrostatic water treatment is a method of conditioning water using the physical and electrochemical effects of electrostatic fields to disperse tiny particles. Essentially it is a method of deposit control.

2. How does it work?
The electrostatic chamber forms a local capacitor within the water and the piping system or vessel wall. Tiny particles that would be part scale, sludge or bacterial deposits are charged to the same electrical polarity as the field created with the electrostatic chamber. These particles then will repel each other much the same as poles of a magnet repel each other.

3. What kills the bacteria?
The positive charge given to the surface of the bacteria draws in negative ions from the surrounding water that attach to the surface of the bacteria in higher concentrations than is normal. The resulting excess concentration of naturally occurring ions weakens the walls of the bacteria and interferes with their ability to absorb nutrition and to reproduce. As a result, they are not able to follow their normal life cycle and will begin to die as they reach their normal life expectancy, typically within two to three days.

4. Does the electrostatic treatment cause corrosion?
No. The electrostatic field cannot cause corrosion because there is no electron transfer as a result of the electrostatic treatment. Once scale, sludge and bacterial deposits are removed from the system, corrosion normally caused by these deposits will be controlled as well.

5. What kind of water testing will I need to do?
Since chemical adjustments are not being made there is no need for testing to determine the levels of chemicals within your system. No acid is fed, so no pH reading needs to be made to avoid over feed or under feed of the chemicals. Periodic checks of the concentration of the total dissolved solids (TDS) in the water are made and the ratio is controlled by monitoring conductivity or chlorine content of the circulating water.

6. Can I eliminate tower bleed altogether?
There are some non chemical devices (NCD) for the treatment of process water systems that proposes to eliminate bleed by filtration or other methods. MTI feels that except in special conditions the normal and proper operation of a tower will involve bleeding or blow down to maintain the water at 4 to 6 cycles of concentration. Very little is saved by higher concentration and the opportunity for problems are increased if it is allowed to go unchecked.

7. Will old deposits of scale be removed?
Old deposits will be loosened and dissolved slowly. If the deposit is sufficiently thick to cause a heat transfer or interferes with flow efficiency it should be cleaned before startup. We recommend starting with a clean system.

8. Do I need to be concerned with turning the system on or off?

The electrostatic system should remain on at all times. During times when a system is not in use it is important to be sure that the electrode is immersed in water.

9. How much power does the electrostatic system use?
Since there is no current flow with the system about the only power usage is the heat loss from the power supply and for the operation of the monitor light or other options added to a power supply. That consumption represents minimal cost per day of operating cost.

10. It is dangerous?
No. There is no danger in being close to the electrostatic system. The system has been designed to eliminate the risk of shock if it is properly maintained. About the only possibility of shock would be in the event that you were to cut the high voltage wire enclosed in the conduit. While the voltage used to create the electrostatic field is very high the available current is very low and is considered too low to be harmful beyond an uncomfortable jolt if directly encountered. If the system should short to ground, the internal control of the power supply will reduce the current output to near zero. The potential for hazardous shock is less than one would normally experience working with a typical household appliance.
