Advances in desalination technology
Seawater desalination has been the cornerstone of the Middle East's water supply strategy since the mid-1950s, and most of the installed desalination capacity is still provided by multistage flash evaporators. But, desalination is changing. In fact, the term "desalination" is no longer limited to seawater applications; desalination technologies are now routinely employed to desalinate brackish ...

The effect of wastewater pretreatment on nanofiltration membrane performance
Membrane fouling is considered a serious obstacle for operation and cost efficiency in wastewater treatment using nanofiltration (NF). However, pretreatment is the most practical way to reduce this prior to NF. In this research, two types of wastewaters were pretreated with different methods prior to NF to examine the effect of pretreatment on membrane fouling in terms of turbidity, chemical ...

A New Fast Acting Low PH Cleaner Paves the Way for a New Cleaning Philosophy for Integrated Membrane Systems
Abstract For many years ultrafiltration/microfiltration (UF/MF) has been replacing multi-media filtration as a seawater reverse osmosis (RO) or nanofiltration (NF) pre-treatment system. Initially the systems were treated as individual unit operations and optimized as such. However, the similarity in the flux maintenance requirements of the particle removal membranes and the desalination ...

AMIAD’s Filtomat Microfiber for RO Pre-Treatment
In this feature article, we outline the effectiveness of Amiad Filtomat Microfiber automatic self cleaning filter technology when used in reverse osmosis (RO) pretreatment for the production of potable water. The Filtomat provides effective prefiltration of various water sources prior to RO. We examine how the pre-filtration technology operates and how it can be integrated into a RO system. We ...

Industrial water reclamation using polymeric membranes – case studies involving a car manufacturer and a beverage producer
This study presents the evaluation of different polymeric membranes for the reclamation of wastewater generated by two manufacturers. Specifically, ultrafiltration (UF) membranes were evaluated for wastewater pretreatment use while nanofiltration (NF) and reverse osmosis (RO) membranes were evaluated for wastewater reclamation use. Results show that both the UF membranes used were not suitable ...

Innovative seawater intake for reverse osmosis desalination plants
Seawater desalination plants typically consist of four major unit operations: seawater intake, pretreatment, Reverse Osmosis (RO) stage, and posttreatment and brine discharge. The best way is to go through vertical beach wells, but the increase of the production capacity of the plants built in recent years makes open intake the only solution. These open ocean intakes draw seawater through the ...
