The Effect of Aeration on Silica Scaling

Abstract

Silica scaling rates have been measured for separated water at Ohaaki BR22 well. oxygen into separated water streams of differing temperatures has no effect on the rate of silica deposition, because the silica present has not polymerised. observed a silica scaling rate of 0.42 for a supersaturation level of 1.92 at of 8.9. The mechanism of silica scale formation probably involves cementation of preformed colloid particles onto the walls of the pipes. polymerisation of monomeric silica has been measured at three different temperatures and no induction period has been observed.
