Paper gives a decision matrix to determine the best method of concentrate disposal for a particular region....

Overview of the preliminary work of the Affordable Desal Coalition to prove the reliability and affordability of seawater reverse osmosis....

The Affordable Desalination Collaboration (ADC) is a California non-profit organization composed of a group of leading companies and agencies in the desalination industry. Using a combination of energy efficient, commercially available RO technologies including pumps, membranes and energy recovery equipment, the ADC has demonstrated (in a two-phas...

This paper will present the approach for incorporating new electrical service for the RO treatment plant, RO treatment facilities,addition of blending water for post-treatment corrosion control, post treatment system for degasification and odor control and a high service pump station at the Pinewoods membrane facility. Operational results after pla...

The mission of the Affordable Desalination Collaboration (ADC) is to promote seawater desalination using reverse osmosis (SWRO) as an affordable, viable source of fresh water. In order to accomplish this mission the ADC seeks to demonstrate affordable desalination using off-the-shelf technology and to create a body of data that can guide & benefi...

The importance of reducing energy consumption has grown as more utilities, particularly in California, consider green house gas emissions reduction as a key parameter in their design and planning process. This presentation covers both conventional and innovative applications of energy recovery and present case studies, energy consumption, energy sa...

This powerpoint presents an overview of concentrate disposal options for inland desalination facilities. Case studies include brine minimization/recovery and zero liquid discharge examples....

Average brackish water RO recovery is about 75% in southern Florida. With an anticipated capacity of 540 mgd by 2025 and increase in recovery to 95% would yield over 100 mgd of potable water. A two phase study was conducted to evaluate possible concentrate management techniques to increase RO recovery. Stage 1 involved a literature review and feasi...

This presentation provides an overview of membrane systems residuals management. It covers residuals from Microfiltration (MF), Ultrafiltration (UF) as well as Reverse Osmosis (RO) and Nanofiltration (NF). Practical and beneficial reuse considerations are explained....

This PowerPoint discusses operator experiences at reverse osmosis plants....

This presentation discusses reverse osmosis (RO) and nanofiltration (NF) concentrate management options, existing technologies, case studies, and emerging technologies. Concentrate disposal, beneficial reuse, and concentrate treatment options are presented along with approaches for achieving zero liquid discharge. Technologies discussed include sec...

Provides an overview of post-treatment for brackish and seawater desalination, including comparison of corrosion indices, explanation of calcium carbonate chemistry, and discussion of alternative post-treatment approaches....

There are many grades and types of stainless steel and stainless steels are used extensively in brackish and seawater membrane treatment facilities. Stainless steel corrodes when the wrong grade or type is placed in the wrong environment. Guidelines and specifications have been developed to create a uniform approach to selecting the proper stainles...

Although the City of Santa Barbara's seawater desalination plant and intake are exempt from the Ocean Plan Amendments' (OPA) requirements, the City has chosen to conduct its subsurface intake (SSI) study using the technical criteria presented in the OPA. This paper presents the OPA's SSI feasibility analysis requirements and summarizes the SSI feas...
