The Long Beach Water Department (LBWD), similar to many Southern California
utilities, have been facing the issue of decreased potable water supplies. Because of its
location, the City of Long Beach is ideally situated to take advantage of desalinated
seawater as a source of drinking water. However, the primary barrier to seawater
desalination has been its relatively high cost as compared to other available water
sources. One method of reducing the operational cost for seawater desalination being
proposed by LBWD is through a two-pass nanofiltration (NF) membrane process, which
has the potential of lowering the overall energy required. In this configuration, permeate
from the first pass is treated by the second pass membranes in order to produce potable
water. This paper presents LBWD's investigation into the behavior of these lower-pressure
membranes during seawater desalination. Includes 10 references, tables, figures.
