Verfahren zum Zuführen und Auffangen von Lösungen

摘要

It is known to supply solution to a process and to collect effluent therefrom using 'bag-in-box' arrangement each having a predetermined volume. However, if the process must be supplied with greater volumes of solution, the use of larger 'bag-in-box' arrangements is limited by weight restrictions that an operator can handle. Described herein is a method of using a number of 'bag-in-box' arrangements coupled together to provide a larger volume of replenisher solution to a process and to collect of effluent therefrom than would be the case if only a single 'bag-in-box' arrangement is used. An automatic changeover system can be utilised which allows the process to be supplied with a greater volume of solution than that which corresponds to the legal weight limit without having to empty the supply 'bag-in-box' arrangements into a large replenisher tank.
