The method includes passing oilfield produced water through a chain of filters, first filter configured to filter particles of a size larger than 10 μm from the water, a second filter configured to filter remaining particles of a size larger than 2 μm from the water and a third filter configured to filter remaining particles of a size larger than 0.5 μm from the water and automatically cleaning at least one of the filters.
