Ultrasound-assisted forward osmosis desalination using inorganic draw solutes

Muhammad Qasim, Faisal W. Khudhur, Ahmed Aidan, Naif A. Darwish

Ultrasonics Sonochemistry > 2020 > 61 > C

Internal concentration polarization (ICP) represents a serious challenge in forward osmosis (FO) desalination since it causes a significant decline in the water flux across the membrane. Mitigation of ICP is cumbersome since the phenomenon occurs within the membrane porous support layer and mitigation procedures such as inducing turbulence or changing the hydrodynamic conditions tend to be ineffective...

Forward osmosis desalination using ferric sulfate draw solute

Muhammad Qasim, Faisal Mohammed, Ahmed Aidan, Naif A. Darwish

Desalination > 2017 > 423 > C > 12-20

Lack of suitable draw solutes is one of the major limiting factors hindering commercial realization of forward osmosis (FO) desalination process. This study investigates the feasibility of ferric sulfate as draw solute in FO desalination. A laboratory-scale, cross-flow FO apparatus utilizing commercial FO membrane (cellulose triacetate-based) was used to desalinate synthesized (5000ppm NaCl) brackish...

Algae personification toxicity by GC–MASS and treatment by using material potassium permanganate in exposed basin

Ahmed Aidan Al-Hussieny, Esam Abd Alraheem, Haider Y. Lafta, Mohammed K. Shebli, more

Egyptian Journal of Petroleum > 2017 > 26 > 3 > 835-842

This study was conducted to address algal toxins using potassium permanganate through the control of biomass growth of algae under following conditions value 25±1 °C illumination intensity value 245microeinstein/m²/s, using the culture media Chu-10 Modified for the purpose of development algae. We treated algal toxins belonging to groups of Neurotoxins, Hepatotoxins, Pyriproxyfen, Emodin, Brevetoxins-10...

Microbial desalination cell technology: A review and a case study

Henna M. Saeed, Ghaleb A. Husseini, Sharifeh Yousef, Jawaria Saif, more

Desalination > 2015 > 359 > Complete > 1-13

The microbial desalination cell (MDC) is a newly-developed technology which integrates the microbial fuel cell (MFC) process and electrodialysis for wastewater treatment, water desalination and production of renewable energy. Due to free energy requirements and environmentally friendly technologies, MDC recently received considerable attention for desalination and wastewater treatment. The technology...

Copper sulfate as draw solute in forward osmosis desalination

Raafat Alnaizy, Ahmed Aidan, Muhammad Qasim

Journal of Environmental Chemical Engineering > 2013 > 1 > 3 > 424-430

Copper sulfate is presented as a viable draw solute in forward osmosis (FO) for brackish water desalination. In this study, the osmotic pressure of copper sulfate was calculated as a function of concentration. An investigation into the osmotic pressure revealed that copper sulfate draw solution cannot generate enough osmotic pressure to extract water from seawater feed. A laboratory-scale FO unit...

Process design of waste gas treatment from Emirates Gold Refinery

Ahmed Aidan, Raafat Alnaizy, Valentin Nenov, Omar Abdelrahman

Clean Technologies and Environmental Policy > 2011 > 13 > 3 > 447-457

In this case study, the process modifications and improvement to the existing process at the Emirates Gold refinery (in order to meet the United Arab Emirates (UAE) nitrogen oxides air emission regulations) is presented. In the past, Emirates Gold refinery used a single small scrubber to treat waste gases. In order to treat the waste gas efficiently, it was found that a cooled oxidation reactor (oxidizer)...

Experimental investigation of phenolic wastewater treatment using combined activated carbon and UV processes

Ahmad Hamad, Ahmed Aidan, Mohammed Fayed, Mehrab Mehrvar

Clean Technologies and Environmental Policy > 2005 > 7 > 3 > 177-181

Experimental investigation shows that UV/hydrogen peroxide (H₂O₂) oxidation of a more concentrated phenolic wastewater can lead to economical savings. The savings can be achieved by the lower amount of H₂O₂ required and time needed to treat the wastewater. Phenolic wastewater can be concentrated by treating the bulk wastewater with activated carbon. The concentrated wastewater that is generated from...

Cost-effective wastewater treatment and recycling in mini-plants using mass integration

Ahmad Hamad, Ahmed Aidan, Muataz Douboni

Clean Technologies and Environmental Policy > 2002 > 4 > 4 > 246-256

. This work illustrates the use of a mass integration approach to cost-effectively reduce wastewater treatment and discharge in mini-industrial plants. The approach focuses on the use of functional analysis, graphical analysis tools, and mathematical formulation to simplify the size of the problem and identify separation/interception scenarios. Sensitivity analysis is then used to compare all potential...
