  • Patent number: 11986581
    Abstract: A water source, an acid source, an electrolyte tank containing a mixture of electrolytes in exactly the quantity needed for the manufacture of the liquid acid concentrate, and a sodium chloride source are connected to a mixing tank. A quantity of water needed for the manufacture of the batch of liquid acid concentrate is introduced into the mixing tank. A quantity of acid needed for manufacture of the liquid acid concentrate is introduced into the mixing tank, the solution is stirred until a homogeneous solution is obtained. Part of the solution contained in the mixing tank is transferred into the electrolyte tank, then the solution contained in the electrolyte tank is transferred into the mixing tank. A quantity of sodium chloride needed to manufacture the liquid acid concentrate is introduced into the mixing tank. The solution is stirred and recirculated until a homogeneous liquid acid concentrate is obtained.
