Abstract: Computer-implemented methods and systems for intelligently controlling a reverse osmosis (RO) machine. The method (which can be executed by a system) can include a processor(s) determining variables related to operation of the membranes of an RO machine by measuring, over time, operating limits of the membranes. The processor(s) can iteratively determine variables (e.g., measured and inferred) related to operation of the membranes by applying an iterative mathematical model to determine a portion of the inferred variables. The portion includes one or more critical variables that cannot be measured directly. The processor(s) determines, based on the variables, an upper limit and a lower limit for various control parameters within the RO machine; control parameters are controlled by active components of the RO machine. The processor(s) derives, for each of the various control parameters, an adjustment. Implementing the adjustment obtains optimal permeate recovery in the RO machine within the operating limits.

Abstract: A fluid delivery device has a syringe barrel with reservoir chamber for fluid, a plunger that translates along a longitudinal axis to expel fluid, and a pusher dimensioned to translate within the barrel and coupled to a drive mechanism to controllably contact and move the plunger. The pusher contacts the plunger at its mechanical center to reduce tilt in the plunger. Contact faces of the pusher and plunger cooperate as a ball joint to minimize non-axial forces on the plunger face. The pusher can have a protrusion of various lengths extending toward and being at least partially received in a recess of various depths in the plunger. The pusher is rigidly connected to a drive mechanism for anti-rotation. The pusher can have scalloped edges for air venting, and apertures for cooperating with protrusions on the drive mechanism to prevent bottoming out the plunger when filling.

Abstract: A method of preparing reverse osmosis membrane with double network of charged hydrogel and polyamide includes the steps of: (a) preparing an aqueous phase polymer solution containing m-phenylenediamine, polymer monomer with ionic group and crosslinking agent, and an organic phase polymer solution containing trimesoyl chloride and photoinitiator; (b) preparing a reverse osmosis membrane by inducing reaction of the aqueous phase and the organic phase polymer solution under ultraviolet light to form a charged hydrogel layer and a polyamide layer respectively; and (c) cleaning the membrane. The hydrogel layer not only enhances the electrical properties, thereby limiting the dissolution of ions in water on the membrane surface and the diffusion of ions in the membrane, and reducing the ions passing through the membrane, but also improves the hydrophilicity, which is beneficial to the transmission of water molecules within the membrane and the improvement of the anti-fouling performance of the membrane.
