Abstract: The disclosure relates to enhancing alkalinity of brine, e.g. seawater, using bipolar membrane electrodialysis (BPMED) without removing divalent cations that otherwise cause scaling. In one embodiment, a BPMED is employed wherein the brine volumetric flow rate through a basification compartment is greater at a given current density than that through a brine compartment which increases the pH of the brine output while keeping it below the precipitation pH. In one embodiment, the spacer located in the basification compartment is thicker than spacers elsewhere in the BPMED so as resist membrane distortion due to the increased hydrostatic pressure in the basification compartment given the greater volumetric flow. The brine output having increased alkalinity can be returned to the ocean to mitigate acidification and enable capture of atmospheric carbon dioxide.

Abstract: A novel reverse osmosis or nanofiltration system (RO/NF) capable of detecting and responding to onset of fouling within the system utilizing uniquely configured membrane permeate flow path within the system which generates a time-sensitive data. Membrane performance data in real-time operating conditions is then utilized for rapid detection of membrane fouling, fouling rate, and cause of fouling, followed by controller-based system generated actions to stop, and recover from fouling or slow-down fouling, and, if required, to predict, plan, and schedule operator intervention steps to recover optimum system operating conditions. The end-result is a novel energy-efficient and fouling-managed advanced (machine learning) reverse osmosis system for brackish water desalination.

Abstract: An apparatus includes a filtration skid configured to generate a filtrate through at least one of microfiltration and ultrafiltration. The apparatus further includes a desalination skid fluidly connected to the filtration skid. The desalination skid is configured to perform reverse osmosis desalination on the filtrate to generate a permeate, where the filtrate travels from the filtration skid to the desalination skid without traversing a storage tank. In one embodiment, the apparatus further comprises a controller, where the filtration skid and the desalination skid are integrated to provide self-adaptive operation of the filtration skid and the desalination skid in response to control by at least one of a supervisory controller and a local controller. In one embodiment, the control responds to at least one of temporal variability of feed water quality, a permeate production capacity target, and a permeate quality target.

Abstract: A fluid purification system has cells whose purifying capability can be regenerated. Some of the cells are arranged in series to reach a high level of purification. An automatic valve network is controlled to cycle the cells in a way that levels the loads on each, thereby maximizing the service interval for replacing expired cells, enabling all of the cells to be replaced at the same time after having each contributing approximately equally to the purification load, and operated such that at any one time, at least one cell is regenerated so as to enable continuous up-time.
