摘要： A water treatment unit having: (a) a cooling tower; (b) a source of cooling water; (c) a main flow pipe for receiving the cooling water; (d) a source of fresh water connected to the source of cooling water; (e) a heat exchanger for heating the cooling water to form heated water; (f) a branched flow pipe for separating the heated water into a main stream of heated water and a partial stream of heated water; (g) a non-backwashable filter capable of separating waste contained in the partial stream of heated water into a compact waste residue and a first filtrate, in the absence of backwashing; and (h) a return pipe for transporting the main filtrate back to the cooling tower, wherein the cooling water is introduced through the main flow pipe into the heat exchanger where it is heated, after which it is split into a main stream of heated water and a partial stream of heated water, the main stream of heated water being transported back to the cooling tower, with the partial stream being transported, by way of the branched flow pipe, into the non-backwashable filter where it is separated into the first filtrate and the compact waste residue, the first filtrate then being transported to the cooling tower through the return pipe.

摘要： The invention concerns a method of determining the concentration of an iodine-iodide-containing active substance in aqueous solutions intended for use in the cleaning or disinfection of containers such as bottles, drums, kegs, cases and tanks and/or pipe lines in the food-processing industry, as well as for industrial scale cleaning in continuous washing plants, the concentration of the active substances in the solution being measured by determining the iodine/iodide content of the solution. The invention provides a rapid, reliable and accurate method which is not prone to interference and can be used on a continuous basis. In addition, it makes it possible to automate the process by which the active substance is kept at the required concentration. In particular, the method proposed can be employed in an integrated cleaning-in-place system. These advantages are achieved by the invention by virtue of the fact that the iodide ion concentration in the solution is measured potentiometrically using electrodes which behave selectively toward iodide ions, and the concentration of the active substance calculated from the measurement results obtained, the iodine/iodide concentration lying between 0.1 and 1000 ppm, in particular between 1 and 20 ppm.
