Abstract

See full text

The invention relates to a method of raising the pH of a body of water having a pH of less than 4.5 by introducing neutralizing agent, the raising of the pH taking place in at least two stages thus: at pH levels below 4.5, a first neutralizing agent having a final conductivity of not more than 100 μS/cm, and, after attainment of a pH of at least 4.5, a second neutralizing agent, having a final conductivity of more than 100 μS/cm, is introduced into the body of water, the final conductivity of the neutralizing agents being defined as the conductivity of an aqueous suspension or solution of neutralizing agent in solution equilibrium at 25° C., having a neutralizing agent content of 0.015% by weight.
