What is oxidisability:
This is the level of organic content of water, and of those inorganic constituents that are amenable to oxidation, whether naturally or from added wastes. The oxidisability or organic content is a good indicator of the overall water quality. It indicates pollution in the source and in treated water it gives a good indication of the success of the treatment process.
How does it get into water?
There will usually be some in the source. There will be a considerable amount of organic content in surface water and a good bit less in ground water sources. The more organic content in the water, the more it will feed bacteria that will use up the dissolved oxygen in the water source.
Does it pose a risk to health?
It does not pose a direct risk to health, but there are several risks associated with a raised organic content in water, a large one being the formation of THM’s in the water when it reacts with chlorine.
How do I prevent this?
The best way to prevent this is to ensure your source is adequately protected from any sort of pollution, also ensure that your filters are appropriate for water and that there is adequate maintenance and cleaning of your filters.
