Abstract
Flocculation method has been developed for the recovery of Cryptosporidium oocysts from water. Flocculation is usually used by water treatment industries worldwide, as a first step in drinking water treatment. It is used as an alternative to filtration method for the concentration of Cryptosporidium oocysts from water samples. It requires basic laboratory equipment only and procedures that follow are much simpler and less labor-intensive than those of filtration method. Ferric sulfate flocculation could apply successfully for the detection of low numbers of Cryptosporidium oocysts in tap water. This chapter presents a study in which ferric sulfate has been tested for the purification of low numbers of C. parvum oocysts from water samples. More than 70% oocysts' recovery was obtained after seed of 2.5 oocysts/L and 1 oocyst/L in tap water samples. Ferric sulfate flocculation should be preferred when viability of the detected oocysts becomes a matter of great importance.
