Advantages of CleanOxide

  • Effective at concentrations as low as 0.1 ppm
  • Effective over a broad pH range (4-10).
  • Controls pathogenic organisms such as 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.
  • CleanOxide 75 is not corrosive at the recommended dose rates
  • Rapidly degrades to harmless inorganic chemicals when exposed to sunlight.

CleanOxide Liquid 75 from Natural Water Solutions is a simple modern method of generating high purity Chlorine Dioxide (ClO2) as and when required by mixing two precursor solutions.

Compatibility of Chlorine Dioxide with Reverse Osmosis Membranes

Reverse osmosis membranes are made of a variety of polymeric materials as well as composites of several materials.

In general, chlorine dioxide has been shown to be compatible with commonly used Reverse Osmosis membrane materials at low concentrations (<3mg/L) well above the recommended rates at which CleanOxide Liquid 75 is used.

Many of the reported problems with chlorine dioxide reacting unfavourably with Reverse Osmosis membranes can be traced back to impurities in the chlorine dioxide such as free chlorine or high levels of acidity (low pH). CleanOxide is totally devoid of any free chlorine and is not acidic when diluted with water.

However, Natural Water Solutions strongly recommends that CleanOxide Liquid 75 is tested on a small portion of the membrane at the maximum proposed rate, if there is any doubt about the compatibility of the membrane material with chlorine dioxide.

It should also be noted that because chlorine dioxide is a gas dissolved in water and is not hydrolysed by the water, it can diffuse into the membrane and pass through the membrane to provide biocidal protection downstream of the membrane. This may be of considerable advantage in some situations where the discharge water is for drinking.

In other situations, where very high purity in the discharge water is paramount, great care should be taken to use CleanOxide Liquid 75 only occasionally to control biofouling.
