Ocean Discharge from Seawater Desalination Plants
Overview of desalination water treatment plant residuals and their alternatives for disposal. Environmental and regulatory issues are offered as well as insight on the environmental impact study process needed to permit many facilities....
Pilot Testing of Alternative Pretreatment Systems for Large-Scale Seawater Desalination Plants in Southern California
The purpose of this paper is to provide description of the Carlsbad pilot desalination plant and to discuss pretreatment system and RO facility performance under various testing conditions....
Project Costs and Financing
This guidebook summarizes membrane desalination technology including reverse osmosis (RO), nanofiltration (NF), and hybrid systems. Discussion includes both capital and operating costs as well as lists of full scale example projects....
Latest Developments in Pumps and Energy Recovery
This presentation provides an overwiew of the types and key performance parameters of high pressure reverse osmosis system feed pumps and energy recovery devices widely used for seawater desalination today. The presentaton describes alternative types of pumps and energy recovery devices, and explains their key advantages and disadvantages....
Minimization of Desalination Energy Consumption Using Emerging Technologies
Reducing energy consumption is critical for lowering the cost of desalination and addressing environmental concerns about greenhouse gas (GHG) emissions from the continued use of conventional fossil fuels as the primary energy source for seawater desalination plants.In this study, a comprehensive literature review was conducted to gather informatio...
Seawater Desalination Energy Minimization Using Nanocomposite and Semi Batch RO
Seawater desalination is a promising option for a steady supply of high-quality water from the abundantly avialable source of ocean water, but the process is energy intensive. In this paper, nanocomposite RO and semi batch RO were evaluated at the pilot scale for energy minimzation during seawate desalination. The objecties were to: 1) compare the ...
Database of Permitting Practices for Seawater Concentrate Disposal
This paper describes the recently completed ?Database of Permitting Practices for Seawater Desalination Concentrate,? a WateReuse Research Foundation project, which could benefit both the utility and regulatory communities in the United States, bringing clarity to the permitting process and issues associated with the construction of desalination p...
