When applying a method and an arrangement for purifying water, an inflow of contaminated water is converted to a pressure elevated flow which is divided in a purifying unit into a purified outflow and a contaminated outflow, which in turn is divided into a return flow and a reject flow. With the intention of providing a large return flow under high pressure for the purpose of rinsing clean the filter unit during operation, the return flow includes a first return flow (return conduit 24) which is recycled to the pressure-elevated flow (pressure conduit 16...
1. A method for purifying water, comprising: (a) converting an inflow of non-purified water to a pressure-elevated flow; (b) dividing said pressure-elevated flow by any one of reverse osmosis, nanofiltration and ultrafiltration, in a purifying unit, into a purified outflow and a concentrate outflow; (c) dividing said concentrate outflow into a first return flow and a second flow; (d) returning said first return flow to said pressure-elevated flow at a flow rate substantially larger than that of said inflow; (e) dividing said second flow into a thi...
