Abstract
The method relates to the operation of a cross-flow filtration installation for a product. This installation includes a filtration module (6), a pipeline (3) for the inflow of the product, a pipeline (9) for removing the product, a pump (4) with an electric motor (12) for recirculating the product, and a control valve (5′) for setting the conveying flow (Q1) of the pump (4). In order to make possible the maximally possible filtration output, based on the installation, along with a high proportion of solids of the product, without endangering operational safety by means of overloads, the strength of the operating current (i1) of the electric motor (12) is measured. The operating current (i1) is adjusted to a maximally, permissible value via a regulator (20) by setting the conveying flow (Q1) of the pump (4) by adjusting the flow control valve (5′).
