Abstract: A liquid pumping system comprises a plurality of liquid pumps and a hydraulic drive unit. Each liquid pump is driven by a separate hydraulic cylinder. The hydraulic cylinders are powered by a shared hydraulic pump through a valve set. A valve set controller is configured to operate the valve set. A liquid pumping process comprises distributing an initial flow of pressurized hydraulic fluid between the hydraulic cylinders. The hydraulic cylinders move through a cycle in a phased relationship to provide a constant sum of flow rates from the liquid pumps. A membrane filtration system combines the liquid pumping system with a membrane unit. In a water treating process, feed water is pumped through the membrane unit. Brine from the membrane unit is returned to each liquid pump while that liquid pump is feeding water to the membrane unit.

Abstract: According to present embodiments or aspects thereof, a composite booster spool with separable composite blades is provided. The blades are inserted radially from within the inner circumference of the spool and extend outwardly through the spool. The system provides a reduced weight assembly as compared to prior art metallic or composite/metallic combination systems. Additionally, the blades are separable which results in a more field-serviceable assembly over a fully integral system wherein the blades and spool are integrally formed from composites or combination of metal and composites.

Abstract: A filtering module, for example a nanofiltration or reverse osmosis module, is made of membranes arranged in a stack with flat sheets of feed channel spacer and permeate carrier. The stack has packs formed of two membrane sheets sealed on four sides and enclosing a permeate carrier. The packs alternate with sheets of feed channel spacer through the thickness of the stack. One or more permeate-collecting pipes pass through the thickness of the stack. The sheets of feed channel spacer have seals along two sides and around the permeate-collecting pipes. A module is formed by placing one or more stacks in a pressure vessel with a seal between the stack and the pressure vessel at a downstream end of the stack.
