Abstract

A method of concentrating sediment suspended in natural waters uses a simple hydrocyclone to effect a separation of coarse and fine particles. A pumped water sample containing suspended sediment passes through a hydrocyclone and is separated into a small volume of high sediment concentration and a larger volume of low sediment concentration. Practical experiments give the dimensions of the hydrocyclone and the flow parameters necessary to separate sand size particles from silt and clay. Results from field trials and comparisons with a filter apparatus show that the hydrocyclone is superior when used to sample areas of high mud concentrations.
