Agriculture & Post-Harvest

producePressure Techniques’ ozone systems help growers and post-harvest operations deliver a product that is higher quality and lasts longer.  Ozone inhibits ethylene production and is safe for contact with fruits, vegetables and flowers.  In addition to killing a wide spectrum of bacteria, ozone is also effective against parasites, viruses, mold and pesticide residue.  It is approved by the National Organic Program for processed foods, allowing products that are treated with ozone to be labeled as “organic” or “made with organic”.

Benefits of ozone infused water with post-harvest fruits & vegetables

  • Extends shelf life
  • Improves appearance
  • Neutralizes pesticide residue
  • Will not harm or affect taste of product
  • Breaks down into oxygen & water
  • No chemical wastewater produced
  • Safe to handle
  • Effective against E. coli, Cyclospora, Listeria, Salmonella, Hepatitis A, Shigella, etc.


  • Rinse fruits and vegetables (Flumes, dump tanks, spray washers)
  • Purify irrigation water
  • Sanitize mist and drip systems to prevent clogging
  • Use gaseous ozone for storage rooms and coolers
  • Sanitize contact surfaces

Growing / Greenhouses / Hydroponics

  • The use of ozone in the growing process can reduce or eliminate the use of pesticides
  • Using ozonated water for irrigation has shown to produce greater yields in several studies
