This powerpoint presentation presents the design, construction, and start-up
challenges of the Long Beach submerged seawater intake and pretreatment system. Preliminary water
quality results are provided and compared against other pretreatment methods (i.e.
microfiltration/ultrafiltration membranes) used for seawater desalination. The pretreatment performance of the intake gallery is compared to other
pretreatment methods commonly used by membrane seawater desalination facilities (i.e.
microfiltration/ultrafiltration membranes).
With this novel approach being one of the first of its kind, several challenges were
encountered during the detailed design phase. These design challenges included:
overcoming local hydrogeologic limitations (i.e. poor permeability, minimal sand
depth, etc.);
impact of tidal fluctuations on operating conditions (i.e. pump head, minimal
submergence of gallery) and water quality;
fouling/clogging of intake gallery;
scouring of intake/discharge gallery; and,
regulatory requirements (construction impacts on marine life, construction
dewatering, maintaining public access, etc.). Includes tables.
