Abstract: A filtration system has a filter element with a filtration membrane, a feed inlet and a concentrate outlet on a first side of the membrane and a permeate outlet on a second side of the membrane. A feed line with a feed shutoff valve is in fluid communication with the feed inlet, and a concentrate return line with a concentrate shutoff valve is in fluid communication with the concentrate outlet. A feed pump is in fluid communication with the feed inlet via the feed line and the feed shutoff valve, and a backwash pump is in fluid communication with the permeate outlet. In a priming phase of a backwash operation, the feed shutoff valve and the concentrate shutoff valve are closed and the backwash supply is operable to deliver fluid to the filtration element and equalize pressure between the first side and the second side of the filtration membrane.
