Abstract
A process for the treatment of steam generator blowoff water comprises 3-stage concentration by evaporation: on the first stage – without salt crystallization, and on the second and third stages – with extraction of salt crystals Na2SO4 and NaCl respectively. With the purpose of increasing of salt yield of Na2SO4 and NaCl and their obtaining in a form of market products evaporated water after the first stage of concentration is treated by sulphuric or hydrochloric acid to pH 6-8, residue of silicic acid is settled, separated and dehydrated, filtrate is mixed with a clarified water and decarbonized.
