Paper presents experience with low pressure membrane microfiltration (MF) of seawater as pretreatment for RO desalination, including discussion of seawater intake systems and their effect on the pretreatment design, ways to maximize the performance of a low pressure membrane system and the issues involved in measuring Feed Fouling Index (FFI) and S...

Management of our global water resources is vital to creating sustainable water supplies for potable, agricultural, recreational and industrial use. Reuse is an economic and environmentally sound solution that uses less energy and actually reduces overall waste compared to desalination. Integrating low-pressure membranes with reverse osmosis to tre...

This paper discussed the ?SkyHydrant? system that uses water filtration units to convert contaminated water into clean, potable water that exceeds WHO requirements for potable water. Siemens Water Technologies has partnered with the SkyJuice Foundation of Sydney, Australia to provide these units. The design and operation are discussed....

Siemens? membranes, and the MemJet MBR process, are used in a variety of applications from small package systems to large wastewater treatment plants. This paper includes product information and a look at innovations including two-phase jetting....

When compared to treatment processes with separate reactors for nitrification and denitrification, the benefits of aerated anoxic biological wastewater treatment processes include lower power costs, lower construction costs, and improved effluent quality....

This presentation provides an overview of some of the key procurement terms and conditions from a vendor's perspective. It goes over the key contract terms: liquidated damages, indemnity, limitation of liability, warranty and methods to accelerate the terms and negotiation of conditions....

Two large desalination facilities in Australia are compared; the Perth system uses a pressurized UF while Adelaide employs a submerged UF process. This paper compares the commissioning strategies and challenges associated with each of these UF systems. In addition to start-up challenges, a comparison of the initial operating data of the full scale ...

The variety of pretreatment schemes for Australian desalination facilities with similar intake water quality and regulations are discussed....

This paper discusses the unique membrane installation at the Lynn R. Morgan Water Treatment Plant located in Erie Colorado that the facility uses pressurized microfiltration and submerged ultrafiltration are utilized within the same facility. The paper presents a summary of long term operations and also the fact that multiple surface water sources ...

The City of Gearhart commissioned an ultrafiltration system which utilizes an arsenic co-precipitation step with ferric chloride prior to final filtration with the UF. A modified cleaning strategy is presented in order to address ferric in the feed, and legal constraints associated with reduced flow periods....
