Abstract
A method of concentrating oocysts of waterborne protozoan parasites from water potentially contaminated by dilute densities of the parasites is described. Potentially contaminated water is fed into the separation channel of a continuous separation channel centrifuge. The water is centrifuged for a period of time sufficient to collect the parasitic oocysts and cysts in the channel.

A method of concentrating waterborne protozoan parasites from water potentially contaminated by dilute densities of the parasites, the method comprising the steps of:
- a. feeding the water into a separation channel of a continuous separation channel centrifuge;
- and
- b. centrifuging the water for a period of time sufficient to collect the protozoan parasites in the channel.
A method of concentrating Cryptosporidium oocysts and Giardia cysts from water potentially contaminated by dilute densities of the protozoan parasites, the method comprising the steps of:
- a. feeding the water into a separation channel of a continuous separation channel centrifuge;
- and
- b. centrifuging the water at a speed such that the relative gravitational force inside the channel is about 900.times.g, for a period of time sufficient to collect Cryptosporidium oocysts and Giardia cysts in the channel.
