Continuous Cycle of Water Desalination Utilizing
Hydrogel as Draw Agent.

This document discusses operation of desalination system permanently extracting water from hydrogel draw agent by specially selected wicks. Due to its peculiarity the system combines advantages of both forward and reverse osmosis approaches such as, low power consumption, passive process of a freshwater extraction, continuous duty cycle and scaling possibility. While in modern systems an energy consumption of seawater desalination reaches of about 3 kWh/m 3 , including pre-filtering and ancillaries [1], the same parameter for the specific system expected to be as low as for local fresh water supplyi.e., 0.2 kWh/m 3
