The critical design factors of water-powered tumbling drums containing crushed limestone for the neutralization of an acidic stream or industrial discharge are discussed. The turning moment imparted to the drum by the water should exceed the resistive moment required to tumble the limestone. Sufficient limestone fines should be abraded in the tumbling drum to achieve the required degree of neutralization. Hydraulic performance characteristics are presented for drums of varying hydraulic design. Tumbling drums are best suited to the complete neutralization of mildly acidic waters, in contrast to limestone barriers and fluidized bed reactors which excel for the partial neutralization of highly acidic waters. 11 references, 14 figures.
