Abstract:
A method for filtering seawater onboard a ship involves pumping seawater into a filtration device so that the seawater is introduced into the filtration device at an inlet pressure, flows in the filtration device through a filter element, and after the filter element as filtered seawater has an outlet pressure. A concentrate phase or concentrate removed using the cleaning device at the filter element of the filtration device is carried away from the filter element and has a concentrate pressure. The inlet pressure, the outlet pressure, and the concentrate pressure are measured. A change in filter efficiency of the filter element is recognized by determining a change in a contamination pressure difference between the inlet pressure and the outlet pressure and/or a suction pressure difference defined as the difference between the outlet pressure and the concentrate pressure is controlled depending on the contamination pressure difference.

Claim (Index 13):
A method for filtering seawater onboard a ship with a filtration device, which comprises a cylindrical filter element arranged in a tank and a cleaning apparatus for detaching contaminants from the filter element and for discharging a contaminant concentrate phase consisting of water and the contaminants from the filter element and from the filtration device, the method comprising:\n a) pumping seawater into the filtration device; b) the seawater is passed with an input pressure P_in into the filtration device, flowing the seawater in the filtration device through the filter element and, downstream of the filter element, has an output pressure P_out as filtered seawater or filtrate; c) a concentrate phase or concentrate removed with the cleaning apparatus at the filter element of the filtration device and discharged from the filter element has a concentrate pressure P_conc.; d) measuring the input pressure P_in, the output pressure P_out and the concentrate pressure P_conc. with sensors and transmitting sensor measurements to a control device; and e) identifying a change in filter efficiency of the filter element based on a change of a contamination pressure difference \u0394P F =P_in\u2212P_out between the input pressure P_in and the output pressure P_out, and/or f) controlling an aspiration pressure difference \u0394P K =P_out\u2212P_conc., which is defined as a difference between the output pressure and the concentrate pressure, as a function of the contamination pressure difference \u0394P F =P_in\u2212P_out.
