<p>According to the present invention a new device is provided for preparing biocide solutions of constant concentrations. More specifically, solid biocide is dissolved, in a controlled and monitored way, to provide solutions, all having the same and constant dose of biocide per volume. The new device overcomes the main disadvantage of the existing solid-biocide feeders, namely, the decrease in the biocide concentration with time due to the gradual depletion of solid biocide in the feed container.</p> |
