Abstract: A method for controlling a hollow fiber nanofiltration membrane system with controllable power consumption, including the following steps. A filtration flow rate is determined by the program control system according to preset working conditions and the electricity price and the inlet water temperature obtained by a first monitoring module when the hollow fiber nanofiltration membrane assembly is started to perform a filtration process. The inlet water pressure change and the permeability change are monitored and recorded by a second monitoring module during the filtration process. A flushing mode and a flushing intensity of the cleaning system are determined by the program control system according to the inlet water pressure change and the permeability change during the filtration when the filtration process is completed.

Abstract: A method is presented for checking the integrity of a hollow-fibre fluid filter, in particular a hollow-fibre dialyzer (1), which is constructed from a plurality of hollow fibres (15) enclosed by a membrane, with the steps of: perfusing the inside or outside of the hollow fibres (15) with a fluid, supplying the outside or inside of the hollow fibres (15) with a gas, wherein the gas has a higher pressure than the fluid, and determining a quantity of the gas which penetrates into the fluid through holes in the membrane. The method is characterized in that, after flowing through the hollow-fibre fluid filter (1), the fluid is channelled through a bubble trap (30), and in that a volume of gas (41) collecting in the bubble trap (30) during a predefined or predefinable reference period is determined. Furthermore, equipment for checking the integrity of a hollow-fibre fluid filter (1) is presented.
