摘要： There is described the processing seawater in a subsea facility on the seabed in various methods and apparatus. In various examples, the facility is coupled to at least one well, is configured to provide the well with water to be injected into at least one formation of the well, and comprises filter elements arranged in housings, the filter elements being configured for ultrafiltration or microfiltration. In such examples, treated seawater in at least one of the housings is filtered using at least one filter element, producing thereby filtered water, and at least one filter element in at least one other of the filter housings is cleaned by backwashing performed using at least some of the produced filtered water.

摘要： Filtering system comprising
- at least a first and a second stage membrane filter,
- wherein the first stage membrane filter has a first stage feed inlet, a first stage permeate outlet and a first stage retentate outlet,
- wherein the second stage membrane filter has a second stage inlet, a second stage permeate outlet and a second stage reject retentate outlet,
- wherein the first stage retentate outlet is in fluid communication with the second stage inlet,
- wherein the system comprises pressure sensors (P1, P2, P3) for determining the differential pressure between the first stage feed inlet and the first stage retentate outlet (dP A/B ) and for determining the differential pressure between the second stage inlet and the second stage reject retentate outlet(dPc),
- wherein the pressure sensors are in data communication with a data processor,
- wherein the data processor is configured to estimate a first slope of the differential pressure between the feed inlet and the retentate outlet from the first stage (slope dP A/B ), and a second slope of the differential pressure between the second stage inlet and the second stage reject retentate outlet (slope dPc); and
- wherein the data processor is configured to identify fouling and to compare the estimated first and second slopes and thereby determine the type of fouling; and
- wherein the data processor is adapted to recommend or actuate a preselected cleaning action for the type of identified fouling.
