Abstract Our article deals with the possibilities to treat seawater using commercial nanofiltration polyamide membranes, denoted NF70 and NF , in order to elaborate usable salty aqueous solutions (from high concentrated solutions with total salinity around 70 g/L to isotonic solutions with total salinity in the range of 9 g/L).

The Long Beach Water Department (LBWD) developed an alternative technology to desalt seawater by using dual-staged nanofiltration (NF2). This novel NF system treats the first-stage permeate through a second stage in order to produce finished water with salinity levels that meet drinking water standards.

Develops a selection protocol to assess the suitability of nanofiltration membranes for a dual-staged system as an alternative to traditional reverse osmosis membranes. Also develops practical guidelines for operational optimization and finished water blending strategies as well as a possible basis for minimizing or avoiding disinfectant usage based on the viral removal capability.

Tailored.

With this as a basis, this report investigated The capability of dual-staged nanofiltration for seawater desalination to reduce operational costs was assessed through a research plan divided.

A Novel Approach to Seawater Desalination Using Dual staged Nanofiltration Book Summary: An alternative to desalting seawater by the traditional seawater RO (SWRO) method is a novel dual-staged nanofiltration (NF2) process developed by the Long Beach Water Department (LBWD).

With this as a basis, this report investigated The capability of dual-staged nanofiltration for seawater desalination. With this as a basis, this report investigated The capability of dual-staged nanofiltration for seawater desalination to reduce operational costs was assessed through a research plan divided into four phases: theoretical basis of the system (governing equations, membrane suitability, etc.); operational optimization approaches (pilot tests and use of a predictive model); preliminary strategies for blending desalinated water.

An alternative to desalting seawater by the traditional seawater RO (SWRO) method is a novel dual-staged nanofiltration (NF2) process developed by the Long Beach Water Department (LBWD). A dual-stage nanofiltration (NF) seawater desalination process was investigated as a novel seawater desalination technology, focusing not only on the permeate water quality, but also on the scaling possibility and energy consumption.

Dow Filmtec TM NF90 was used in the experiment for its high rejection of total dissolved solids (TDS). The use of seawater desalination is an increasingly sought after alternative for new drinking water supplies in coastal areas, particularly as desalination becomes more economical.

This new manual of practice parlays lessons learned from recent studies and global seawater desalination projects into guidance for desalination facilities that are. In this study, the applicability of nanofiltration (NF) membranes as a pretreatment prior to reverse osmosis (RO) in seawater desalination was investigated.

The membranes used were NF and NF90 as the NF membranes, while the brackish water (BW) RO membrane BW30 was used as. As a result of this testing, they developed a novel dual-stage (or pass) process using nanofiltration membranes.

With the support of their board of directors, the Long Beach Water Department staff built and tested a pilot scale plant with a capacity of 34 m 3 /day. The results of this testing proved the concept and showed significant potential.

Seawater desalination offers a promising option for the supply of potable water. Seawater desalination is an energy intensive process; nuclear energy is an attractive candidate as an energy source. Combining the use of nuclear energy with the industrial process of seawater desalination has been considered as far back as in the s.

Recently a novel dual stage NF membrane treatment process was suggested for seawater desalination. Researchers claimed that dual stage NF process was able to produce potable water from seawater at a lower cost than RO.

The process was able to desalt seawater by using high performance NF membranes. increased upstream water use, and the thirst for clean and contaminant-free water have stimulated the increased use of membrane processes in water treatment in general, but limited watersupplies inmanyparts oftheworldareincreasingly reliant on seawater desalination.

Investments in reverse osmosis (RO). ED/EDR are typically not cost competitive for desalination of seawater (Amjad ), and NF is not ordinarily considered for seawater desalination for potable water production. However, a novel approach employing two-pass (NF) configuration has been developed and tested for seawater desalination by the Long Beach Water Department in California.

Throughout the world, a trend towards the intensified use of desalination as a means to reduce current or future water scarcity can be observed. Seawater desalination provides such an alternative. Nanofiltration (NF) membranes have applications in several areas.

One of the main applications has been in brackish and sea water treatment for drinking water production as well as for wastewater treatment. NF can either be used to treat all kinds of water including ground, surface, and wastewater or used as a pre treatment for desalination.

Desalination of Seawater - Manual of Water Supply Practices, M61 As worldwide fresh water supplies become increasingly stressed from population growth and uncontrolled water use, desalination of seawater has become an increasingly sought-after alternative for new water supply in coastal areas.

This is a new approach towards the problem of desalination of seawater that has, to the best of our knowledge, not been presented before. In a proof‐of‐principle experiment the salt content of a 10 g/L NaCl solution could be reduced by 35% in one cycle. All over the world, access to potable water to the people are narrowing down day by day.

Most of the human diseases are due to polluted or non-purified water resources. Even today, under developed countries and developing countries face a huge water.
