US 2014/0110316 A1 · Flow Through Adsorber for TDS Ablation

Abstract

Using seawater as a benchmark of water with high TDS (total dissolved solids) Raw seawater can be instantly and significantly desalted just by passing a flow through adsorber (FTA) without applying electricity to the adsorbent therein. Various precursors may be converted to dual-functional adsorbents for the FTA. A cation-adsorbing group and an anion-adsorbing group are grafted onto the surface of the adsorbents by phosphorylation and amination, respectively. Based on the applications, the adsorbent may be configured as membrane form or packed bed in the FTA. When the adsorbent becomes saturated, it can be regenerated online using liquids cleaner than the intake. Besides seawater, the FTA may be utilized for treating other TDS-infested wastewaters at very minimal cost.

Dependent claims

A flow through adsorber (FTA) for TDS ablation comprising:

at least a FTA unit, comprising;
a housing;
and
a dual-functional adsorbent disposed in the housing with at least one configuration, the dual-functional adsorbent comprising a cation-adsorbing group and a anion-adsorbing group on the surface of the dual-functional adsorbent;
at least an inlet on the housing for liquid to enter the FTA unit;
at least an outlet on the housing for the liquid to exit from the FTA unit;
at least a pump to drive the liquid through the FTA unit for TDS ablation;
at least a rinsing liquid to regenerate the FTA unit;
a first electronic controller to control the TDS ablation;
and
