Document Type and Number:
Japanese Patent JP2001314859
Kind Code:
A
Abstract:
To suppress the generation quantity of a resin regeneration waste liquid and to conserve the usage of a regeneration chemical agent in a method for separating and removing boron in wastewater using a boron adsorbing resin.
The pH of the regeneration waste liquid is continuously measured and the supply of an acid and/or alkali used in the regeneration of the boron adsorbing resin is controlled by grasping a sudden change in the pH of the regeneration waste liquid.
