Abstract: Disclosed is a process that uses reverse osmosis (RO) or nanofiltration (NF) membranes and ion exchange (IX) water softening resins to maximize the production of drinking water, purified industrial service water or recycled purified municipal or industrial effluents. The membrane and ion exchange units are configured in a manner that enables operation of the system at high permeate recoveries in the range 90% to 99%, thus producing purified drinking water with a minimum volume of wastewater to drains and a very low membrane cleaning or membrane replacement frequency. The process mitigates membrane fouling and scale formation and minimizes the use of water treatment chemicals including acidic and alkali solutions and sodium chloride salt that is normally required to regenerate the IX resin.

Abstract: A new process for ion exchange softening of water used in Once-Through Steam Generators (OTSGs) by recovering and using the salt content of the blowdown water from the OTSG to regenerate the softener resin is provided, thus eliminating the cost for commercial regenerant salt that would otherwise be needed. Further, the very high purity of the salt recovered in the blowdown inherently results in the production of softened water with hardness leakage levels that are an order of magnitude lower than can be attained using commercial salt, thus reducing scale deposit potential and improving operating efficiency and reliability of the OTSG.

Abstract: The disclosed process for rejuvenation treatment of a photoresist development waste mainly containing a photoresist and tetraalkylammonium (TAA) ions comprises at least a simple membrane separation step of treating the photoresist development waste or a treated solution derived from the photoresist development waste with a nanofiltration membrane (NF membrane) to obtain a concentrate (NF concentrate) mainly containing impurities such as the photoresist and a higher-purity permeate (NF permeate) mainly containing TAA ions. The NF concentrate and/or the NF permeate, preferably the NF permeate, is desirably subjected to a step of concentration and refining by electrodialysis or electrolysis and/or a step of refining by ion exchange treatment, for example, with an anion exchange resin and/or a cation exchange resin in one of the H form and the TAA form. The NF permeate may advantageously be passed through the concentrating cells of an electrodialysis unit while passing the NF concentrate through the desalting cells of the electrodialysis unit to further recover TAA ions remaining in the NF concentrate, whereby the amount of wastewater discharged as the desalted waste can be decreased. The NF membrane separation step is preferably effected in multiple stages.
