OxyFlow 20L

OxyFlow 20L

SKU: 364215375135191

Piping and irrigation:

  • OxyFlow is a plant-based solution for flushing pipelines and irrigation systems and activates positive microbial activity minimising biofilm, calcification and algae development
  • OxyFlow


    Pipeline flush and water conditioner

    What makes OxyFlow different?:

    OxyFlow introduces high levels of slow-release dissolved oxygen and activates positive digestive microbial activity in the pipeline dismantling the structure of sludge and weakening calcification and organic deposits. Consequently, OxyFlow maintains a clean system by continually flushing the pipeline. Additionally, OxyFlows Eco-friendly ingredients provide a high value of oxygen availability and increased positive microbial activity in the water boosting the waters health properties and continue to have positive effects on the destined environment.

    From the Laboratory:

    When OxyFlow is injected into the water pipeline the catalase-like emission of slow-releasing oxygen gas is observed. The reaction is favoured at neutral pH levels and activity is increased in areas of increased organic material. A measured amount of oxygen is produced enzymatically and not by chemical disproportionation of superoxide. A clear correlation also exists between catalase activity and the enzymes' resistance. The production and activation of critical metabolic enzymes are observed however the mechanisms are not yet fully understood.

    The composition includes extracts from a variety of naturally occurring plants. The process of extraction is mechanical with the use of low heating. No genetically modified organisms. Zucconi Germination Index 100% @ 1:24 H₂O dilution; Inhibitor materials <2.00 equitox/m³ Bioluminiscence inhib./C5110184 (non-detectable) @ 1:24 H₂O dilution.

    OxyFlow cleans and flushes pipelines and unblocks nozzles and filters in an eco-friendly manner

    Apply OxyFlow for:

    • Increased dissolved oxygen availability and positive microbial activity in water pipelines.

    • Reduction in bio-fouling; scale deposits, algae, organic buildup, Iron oxide deposits.

    • Flushing of piping systems clogged with organics, algae and calcification.

    • Cleaning sand filters, membranes, grit filters, nozzles etc.

    OxyFlow application instructions:

    OxyFlow Auto-Dosing Program






    System Flush







    10 000

    1 Litre OxyFlow/㎥






    0.1 (1%)


    Apply to mainline auto dosing injector connected to your piping system 1 L OxyFlow to between 800㎥ water (1.25 ppm) and 40㎥ of water (25 ppm) depending on your requirements. Typically starting with a High program and maintaining with the Maintenance program.

    For agricultural, horticultural and hydroponic pipelines: Start with the Maintenance program and evaluate then decide your preferred dosage program never exceeding 12.5 ppm.

    System Flush: flush for piping systems: apply 1 Liter OxyFlow for every 100 litres of water (1:100) in the pipeline. Run treatment within the full length of the pipeline. Leave treated water in the pipeline for 24 hours before flushing.

    *Pipe volume = π x radius² x length, where radius = inner diameter/2. The volume of a pipe is equal to the volume of a liquid inside (if a pipe is fully filled with it).
