This powerpoint presentation begins by presenting a brief overview of the inland reverse osmosis (RO) desalination concentrate disposal issue. The focus of zero liquid discharge (ZLD) research is to develop an economical treatment
technique for desalination that minimizes
or eliminates any liquid waste discharge
from a desalination process. Two Water Research Foundation (WRF) Projects are listed, #3010 - Zero Liquid
Discharge for Inland Desalination
(published 2007); and, #4163 - Zero Liquid Discharge
Desalination of Waters with High
Organic Content (in progress). A schematic of the basic premise is presented, along with removal of sparingly soluble salts, chemical softening, Fluidized Bed Crystallizer (Crystalactor), and activated alumina. Two concentrate treatment technologies are presented: ion exchange, MIEX; and, electrodialysis with ion selective membranes (EDM). A study of Tamiami Groundwater (TGW) treated at the Collier
County North Regional
WTP is outlined, and results are provided for both MIEX and EDM treatments. Includes tables, figures.
