摘要:
The present embodiment relates to a method for recovering a boron adsorbent, including: preparing water having an electric resistivity of 0.01 MΩ·cm or more and kept at a temperature within a temperature range; and contacting the water with the boron adsorbent to release boron adsorbed at the boron adsorbent.
摘要:
A household appliance using water is described, in particular a washing machine, comprising a supply system of water from an external source (8,9), a softening system for at least a portion of the supplied water (10,17), and a control system of the appliance, characterized in that permanent water softening means (10,17,H,21) are provided, which are controlled by said control system and which do not periodic interventions by the user to the appliance, for adding regeneration media and/or replacing components.
摘要:
A process for removing CO2 from the air, comprising the steps of (a) passing the air in contact with a first ion exchange resin to absorb CO2 from the air; (b) passing a CO2 sorbent in contact with the first ion exchange resin to transport CO2 to the sorbent; passing the sorbent from step (b) in contact with a weak base anion exchange resin to absorb CO2 from the sorbent; separating the CO2 from the ion exchange resin by heating the ion exchange resin from step (c) whereby to drive off the CO2 from the resin. Alternatively, the ion exchange resin may be washed with water prior to heating.
摘要:
a water softening system includes a water softening resin tank, an anion resin tank in flow communication with the water softening resin tank, an in-line water heater in flow communication with the water softening resin tank and a heat exchanger in flow communication with the in-line heater. A water heater is in flow communication with the heat exchanger and the in-line heater. A plurality of flow control valves are operatively connected to the water heater heat exchanger, in-line water heater, anion resin tank, and water softening resin tank. The flow control valves are configured to control the flow of water through the water softening system.

摘要:
An improved system of resins comprising a combination of a sulfate-specific strongly basic anion exchange resin and a heterogenous hybrid thermally regenerable salt sorbent (TRSS) resin is provided. The anion exchange resin contains triethylamine and/or tributylamine groups. The TRSS resin comprises a macroporous host copolymer and a crosslinked guest copolymer having, respectively, weak acid groups and weak base groups. The system is used to treat feed water containing dissolved ions, including sulfate ions, and is efficiently regenerated.
