Applications by Industry


Biofouling Control in Pulp. Paper and Paperboard Mill and Water Systems 

Control bacterial, fungal and yeast growth in pulp, paper and paperboard or non-woven process water and influent systems. 


Bottle or Can Sanitizing Rinse

May be used as a final sanitizing rinse for plastic, glass, carton, or metal returnable and non‑returnable bottles and cans.


Citrus Canker Spread Control on Surface and Produce

Sanitizes inanimate surfaces (e.g., tree‑harvesting equipment and containers) to help limit the spread of citrus canker via contaminated surfaces. May also be applied to citrus trees to help prevent the spread of the disease.


Cleaning Drip Irrigation Systems

Cleans slime and algae from drip filters, tapes, and emitters during irrigation cycles, and helps reduce hard‑water scaling.


Cleaning Livestock Water Systems (Offline)

Reduces scale, calcium, iron, magnesium, heavy soils, and polysaccharides in livestock watering systems. When used as directed, it helps reduce organic and inorganic deposits that restrict flow in water‑dispensing systems.


Cleaning Livestock Water Systems (While Animals Present)

Control mineral buildup in operating lines for limited days.


Control of Slime in Cooling& Recirculating Water Systems

Microbial control in cooling towers, evaporative condensers, and pasteurizers.


Evaporated/Condensed Water Treatment

Treatment of condensate water in dairy and food plants.


Industrial Air Washers—Microbial Control

Microbial control in industrial air washing systems.


Oil & Gas Pipelines/Tanks—Microbial Control

Microbial control in water-bottoms of storage tanks, pipelines.


Oil & Gas Well Operations—Antimicrobial Treatment

Controls slime formers, spoilage microbes & SRB in well operations.


Oil & Gas—Flooding/Injection/Produced Water

Biocontrol in flooding/injection/produced waters


Produce Wash Water Treatment (Spoilage/Decay Control)

Controlling spoilage organisms in wash water for produce.


Sterilization of Aseptic Filling Systems and Packaging

Applied to sterilize aseptic filling systems and packaging prior to filling (except infant formula packaging).


Wastewater/Effluent Treatment (Non-Public Health Microbes)

Treat sewage/wastewater effluent to control non-public-health microorganisms.
