In September 2005 California American Water Company (CAW) decided to proceed with a pilot seawater desalination program at Moss Landing near Monterey, California. The objectives of the pilot program are to develop essential design data and to test different technologies and design approaches to facilitate the design of a full-scale desalination pla...

Two examples of development of a water supply for high-end developments in a coastal beach area are discussed in this paper. These developments include five-star hotels, luxury villas, recreational facilities and championship class golf courses. This paper describes the integration of desalination technology to produce several different types of wa...

A novel rotating flat sheet membrane bioreactor was introduced in the wastewater treatment market in 2002. It has since been installed in 20 municipal and industrial wastewater treatment plants. Compared to other MBR systems, the special features and advantages of this technology are low energy demand through sequential cleaning, low energy costs, ...

This paper investigates the efficiency of constructed wetlands for concentrate minimization as compared to traditional evaporation technologies. Using four halophyte species, it is expected that constructed wetlands may increase evaporation/evapotranspiration rates ten-fold....

The city of San Diego is investigating brackish water desalination for groundwater sources in the San Pasqual Valley. A three stage NF-RO-RO high pressure membrane system was designed to treat the groundwater. Iron and manganese concentrations in the source water were higher than expected and led to fouling of the membranes. A slow sand filter was ...

The new RO facility will be co-located with the existing surface water treatment plant. The RO permeate will be transferred through a degasifier and scrubber for H2S removal and odor control. The permeate will facility's clearwells, where it will be blended with the filtered water from the existing disinfected, stabilized and transferred to the fa...

This presentation provides an overview of different types of MBRs and recommends selection guidelines for them. Emphasis is placed on different manufacturers and highlights the importance of target water quality; regulatory and space constraints; power and operational requirements; and costs for making a proper selection....
