Cryptosporidia is a parasite that is of particular concern for pool plant operators because it is not killed by chlorine. The parasites live inside a protective shell called an oocyst which protect them from the chlorine in the swimming pool or spa water. If these oocysts are ingested by swallowing contaminated water, the cryptosporidia with hatch out of the shells and reproduce, causing a gastro-intestinal illness. When the newly-created oocysts are expelled from the body via the faeces, the... Continue reading ...
Coagulation is an important process in the swimming pool water treatment process. It helps to remove very small particles from the pool water. In a conventional swimming pool sand filter, the size of the gaps between the sand grains (pores) are around 70 microns. As the filter begins to trap particles, the size of the pores decreases. This is known as 'filter ripening'. When the filter is fully ripened, it will be capable of trapping particles the size of around 5 - 10 microns. The size of cr... Continue reading ...
Cryptosporidia is an organism that pool operators need to be particularly aware of. The main problem with it is that the chlorine in the pool water will not kill it due to the fact that it is protected within a shell that the chlorine will not penetrate. Cryptosporidia causes an acute gastro-intestinal illness and is introduced into the pool water via faecal contamination. If someone has an accident in the pool and the result is a loose, as opposed to solid stool, you as pool operator are goi... Continue reading ...
