Irrigation Systems

A common problem encountered in all irrigation systems is growth of micro-organisms in the irrigation pipes causing poor flow, blockages and the potential for the spread of disease-causing organisms throughout the irrigated area, particularly fungal diseases.

The micro-organisms flourishing in irrigation pipes include bacteria and fungi and, if sufficient light is present, algae. Irrigation pipes provide an ideal environment for the establishment of biofilm on the inside of the pipes.

Other than mineral build up, the presence of biofilm is the single most likely cause of reduced flow and blockages in irrigation systems. The presence of biofilm also creates a permanent reservoir of potentially harmful micro-organisms throughout the irrigation system.

Biological Clogging Hazards Arise from:

  • Growth of bacterial slimes (biofilm).
  • Growth of algae wherever there is sufficient light available, especially around drip taps and emitters.
  • Biological growth on clay particles contributing to physical clogging of spray nozzles by bridging.
  • Adhesion and agglomeration of fine particulate matter as a result of biological activity.
  • Precipitation of iron and sulphur caused by biological activity.

Control Micro-organisms in Irrigation Pipes

Conventional chlorine, bromine and non-oxidising biocides are very poor at controlling microorganisms in irrigation pipes because of short contact times unless dosed at very high concentrations. Even at high dose rates, these disinfectants do not control biofilm.

High concentrations of disinfectant in irrigation water are also potentially harmful to the plants being irrigated. Most non-oxidising biocides are unacceptable for spraying on to food

Chlorine dioxide overcomes all these problems. It is effective against algae, bacteria, bacterial spores, fungi, protozoa and viruses and is the only method of disinfection that is effective at controlling biofilm.

The Pharma Room: Surface Wash in particular remains effective over a wide pH range from 2 to 10, does not react with ammonia or organic matter in the water and any residual chlorine dioxide on plants rapidly breaks down to harmless inorganic compounds.

In addition to these benefits. Chlorine dioxide, when used at high enough dose rates, will disinfect hard surfaces preventing the spread of disease-causing bacteria, fungi and viruses.

Effectively eliminate blockages with The Pharma Room: Surface Wash

When dosed into the irrigation system at the recommended rate The Pharma Room: Surface Wash will control bacteria, fungi, viruses, algae and biofilm. Higher rates will allow the control of micro-organisms on hard surfaces contacted by the irrigation spray such as workbenches, pots and glass in greenhouses.

  • Effective over a broad pH range (2-10).
  • Controls bacteria, fungi, viruses. biofilm and algae.
  • Does not react with ammonia and does not produce toxic compounds in contact with organic materials present in water.
  • Not phytotoxic at the recommended dose rates.
  • Rapidly degrades to harmless inorganic chemicals when exposed to sunlight.
    Safe for consumption and approved for use in most countries around the world including Canada & the United States.

Chlorine Dioxide removes established biofilm that lines irrigation systems, clogs emitters and can potentially harbour pathogens. For continuous application, a low concentration of chlorine dioxide can be used to maintain clean irrigation lines and to inhibit algae and diseases.

Other Uses

The Pharma Room: Surface Wash can be used in a wide array of other places including but not limited to:

  • Disinfecting stables and pens.
  • Disinfecting well water.
  • Disinfecting equipment and hard surfaces.
  • Odor control for animals / livestock.
  • Animal unpotable water treatment.
  • General surface cleaning.
  • Safe for use on plant vegetables and other plants.
