此powerpoint演示文稿介绍了设计、施工和启动 长滩浸没式海水取水和预处理系统面临的挑战。预备水 提供质量结果，并与其他预处理方法（即。 用于海水淡化的微滤/超滤膜）。将进水廊道的预处理性能与其他廊道进行了比较 膜式海水淡化设施常用的预处理方法（即。 微滤/超滤膜）。 由于这种新颖的方法是同类方法中的第一种，因此出现了一些挑战 在详细设计阶段遇到。这些设计挑战包括: 克服当地水文地质限制（i。 e、 渗透性差，沙子少 深度等）； 潮汐波动对运行条件的影响（即泵头，最小 廊道淹没）和水质； 进水廊道结垢/堵塞； 进排水廊道冲刷；和 监管要求（施工对海洋生物的影响、施工 排水、维护公共通道等）。包括桌子。

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.
