Trends worldwide  Scarcity of water  Pressure to use less chemicals  Pressure to use chemicals biologically friendly  Pressure to use chemicals less harsh on the environment  More government regulations continue to effect spraying practices and techniques.  New more resilient bacterias, and viruses  A public which is “more aware” of illnesses, outbreaks and lawsuits

“The fine line” in spraying Killing the bacteria or virus but Being limited on how, what and where you spray

Mechanical hanical spraying raying has s been aro round und for r ma many y ye years rs Danvill ille Ohio, , 1939 1891

Even with t the advent of excellent ch chemica cals, s, the method of applica cation on has always been j just as important nt.

The side e effects ts of contami mination ation and the “ever increasing” number of government regul ulat ation ions s have also complica icate ted d the spraying ying proces ess. s.

A new option in spraying Electrostatic Sprayers

Automobiles have been painted electrostatically for many years.

Spraying water based solutions? Why not?

For many years, men have tried to put an electrostatic charge on the chemicals that they spray.

18 years ago, the Univ. of Georgia was successful in developing an electrostatic spray nozzle for water based solutions in agriculture.

Liqui uid Air Air Electrode Benef efit its: s: • Air assist sted d spray Negatively • Small droplets charged spray • Low voltage • High attraction

Droplets with Negative Charges Positive Negative charge

The electrostatic attraction is much stronger than the gravitational pull of the earth.

Low Volume Spray Droplets of 30 microns 300 microns

Post Harvest/Food Processing

Small sprayers

Disinfecting and Sanitizing

Emergency Services

Applications  Law Enforcement(Fairfax County Sheriff)  Fire Departments (Chicago Fire)  Hospitals (Nashville General)  Athletic Departments (UGA)  Schools (North Oconee High School)  Detention Centers (Houston)  Public Transportation (Wash. DC Metro)

Electrostatic spraying today  Agriculture, greenhouses, and pre harvest  New emphasis: – Disinfecting and sanitization – Post harvest application of coatings and solutions – Food coatings – Industrial coating
