    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.

Azacrown monomer units are preferably linked with a suitable linking agent, and the resulting polymers are can absorb mercury from a water stream and form a stable complex therewith. Methods of making and using the polyazacrown polymers are also disclosed. The polymers have a high absorption capacity for and selectivity towards mercury, which properties are useful for the remediation of mercury-contaminated water. The polymers can be regenerated by the efficient removal of the absorbed mercury. Further, the absorbed mercury that is liberated from the polyazacrown polymers can be effectively concentrated and captured to prevent its re-release into the environment.
