This paper presents an experimental investigation on the productivity of a basin type solar still with internal and external reflector tilted at angles of 0 degrees (vertical), 10 degrees, 20 degrees and 30 degrees for still cover angles of 20 degrees, 30 degrees and 40 degrees. A simple still equipped with internal and external reflectors is investigated in winter at latitude angle of 33.3 degrees N. It was found that the daily productivity is greater for a still with a larger cover angle at any reflector angle. The daily productivity of the still with no reflectors would remain almost the same at any glass cover angle. The benefit of the vertical external reflector in winter is decreased as the cover angle exceeds 40 degrees. The most productive solar still in winter is a still that has a cover angle of 20 degrees and an internal and external reflector inclined at 20 degrees; its productivity will be around 2.45 times that of simple still with no reflectors. The conclusions of this study validated the trend of some of the theoretical results cited in the literature at 30 degrees N latitude. (C) 2010 Elsevier B.V. All rights reserved.

Raad Z. Homod, Ghazwan Noori Saad Jreou, Hayder Ibrahim Mohammed, Amjad Almusaed, Ahmed Kadhim Hussein, Wael Al-Kouz, Hussein Togun, Muneer A. Ismael, Hussein Alawai Ibrahim Al-Saaidi, Omer A. Alawi, Zaher Mundher Yaseen

Summary: Due to the influence of nonlinearities and high delay time, a hybrid model combining white-box and black-box approaches is developed to handle the behavior of a complex oil field system in Iraq. This model effectively represents the large data sets and achieves optimal fitness to measured values. The conversion of fuzzy rules into a multilayer perceptron network and the use of clustering technique and Gauss-Newton regression enhance the predictive performance of the hybrid model.

Selective separation of nitrate from chloride using PVDF-based anion-exchange membranes

Daniele Chinello, Jan Post, Louis C. P. M. de Smet

Summary: In this study, PVDF-based anion-exchange membranes were designed to selectively separate nitrate from chloride. Experimental data showed that increasing the concentration of PVDF enhanced nitrate transport but also increased the membrane electrical resistance. The selectivity of nitrate was found to be independent of the membrane thickness and mainly driven by the increased affinity between the anion and the membrane.

Zwitterionic material for construction of an antifouling polyamide thin film composite membrane

Dao Thi Thanh Huyen, Saikat Sinha Ray, Young -Nam Kwon

Summary: This study focuses on the modification of a commercially available polyamide thin-film composite membrane with a zwitterionic material to enhance its fouling resistance. The modified membrane shows improved salt rejection and reduced permeability compared to the pristine membrane. Fouling tests demonstrate that the modified membrane has a lower fouling ratio and higher recovery ratio. The enhanced antifouling characteristics are attributed to the improved hydrophilicity resulting from the zwitterionic brushes and the salting-in effect.

Zhiqiang Zhang, Ruifeng Deng, Jiao Zhang, Lu She, Guangfeng Wei, Renyong Jia, Pengyu Xiang, Siqing Xia

Summary: A transmembrane electro-chemisorption system with authigenic acid and base was developed for enhancing ammonia recovery from strong ammonia wastewater. The system efficiently transformed ammonium into free ammonia, which was then adsorbed and recovered through transmembrane chemisorption. This system yielded pure (NH4)2SO4 product and produced valuable byproducts of pure hydrogen and oxygen. Higher applied voltage resulted in better ammonia recovery.

Sanjana Yagnambhatt, Saber Khanmohammadi, Jonathan Maisonneuve

Summary: This study investigates the concept of using heat to enhance reverse osmosis (RO) desalination. The effect of temperature on water permeate flux, specific energy, permeate quality, and applied operating pressures is evaluated using an analytical model. The results suggest that under specific conditions, the tradeoff between savings in mechanical pump work and thermal energy input in thermally-enhanced RO can be favorable, leading to overall energy savings.

Summary: To meet the huge demand for lithium resources, there is an urgent need to develop a new efficient technology for lithium recovery from salt-lake brines. In this study, a selective membrane capacitive deionization system is reported, which achieves high lithium recovery capacity and rate through the use of materials with efficient intercalated pseudo-capacitance and a high specific area porous carbon. The use of a modified thin-coated membrane allows for selective Li+ recovery, and adjusting the concentrations of Li+ and Mg2+ in the feed solution enables higher Li+/Mg2+ selectivity.
