This study examined the performance of a novel hybrid system of forward osmosis (FO) combined with vacuum membrane distillation (VMD) for reclaiming water from shale gas drilling flow-back fluid (SGDF). In the hybrid FO-VMD system, water permeated through the FO membrane into a draw solution reservoir, and the VMD process was used for draw solute recovery and clean water production. Using a SGDF sample obtained from a drilling site in China, the hybrid system could achieve almost 90% water recovery. Quality of the reclaimed water was comparable to that of bottled water. In the hybrid FO-VMD system, FO functions as a pre-treatment step to remove most contaminants and constituents that may foul or scale the membrane distillation (MD) membrane, whereas MD produces high quality water. It is envisioned that the FO-VMD system can recover high quality water not only from SGDF but also other wastewaters with high salinity and complex compositions.

AbstractBackgroundRNAs to be used in transcriptome analysis must be of high quality and pure in order to ensure maximum representation of the expressed genes. RNA isolation is difficult in hazelnut tissues containing large amounts of secondary metabolite, phenolic compounds and the cell wall structure. Commonly used protocols for RNA isolation are those that require a lot of labor and time and also do not allow sufficient RNA isolation when applied to tissues rich in phenolic compounds. This study was aimed to develop an efficient method for isolation of total RNAs from bud of hazelnut to be used in RNA sequencing.Materials and methodsAn optimized new method was successfully applied on three different hazelnuts genotypes (Çakıldak, Palaz, Tombul) and about 25 times higher amount of total RNAs per mg fresh tissues were obtained compared to classical CTAB method. Different methods have been tried for the isolation of RNA from hazelnut tissues and the determination of the quality of the obtained RNAs.ResultsThe quality and quantity of isolalated total RNAs were determined by spectrophotometer, electrophoresis and PCR. This success has been caught without any compromise of purity since A260/A280 ratios ranged from 1.90 to 2.04 and A260/A230 ratios were >2.0 in all purified RNAs.ConclusionThe total RNAs isolated with new protocol was found to be suitable for RNA sequencing and other molecular applications.

The Difference

The optimal decoloring conditions for glutamate supernatant in orthogonal experiment are: 15g/l bentonite concentration, 2h decoloring time, and 40°C decoloring temperature. VMD technology can concentrate glutamate supernatant filtrate from 2.01% to 5.35%, and bring down flux from 6.71 L/m2h to 1.94L/m2h, at a concentration rate of 1.72 times. The glutamic acid concentration in supernatant fluid is enriched from 2.03% to 5.16%, and flux attenuated from 5.47 L/m2h to 1.91 L/m2h. As glutamic acid concentration in supernatant increases, membrane flux gradually decreases. Analysis of water production in glutamate supernatant membrane distillation and the meteorological chromatograms of glutamic acid filtrate prove that the difference between water-yielding peak time of supernatant fluid and that of the filtrate is less than 0.1 min. The volatile substances during water production are from glutamic acid filtrate and are of the same matter. Therefore, the product water in supernatant fluid membrane distillation can be reused to improve water production efficiency.
