As such, comparison between a membrane diffuser and a bubble diffuser in terms of its performance in the cultivation of algae has been made. This work utilized PVDF flat sheet membrane with only air and pure CO2 as the feed gas and the diffusion method used was compared between membrane diffuser and a bubble diffuser. In the experiment, the feed gas flows through the membrane diffuser in which the algae suspension utilized the CO2 for its growth. The biomass contents of four different samples have been determined using the dry weight of the algae suspension samples, which is obtained by drying the samples in an oven overnight at 105˚C. The algae suspension with the membrane diffuser was able to remove CO2 feasibly while showing better performance with respect to algae cultivation in comparison to the bubble diffuser. Results showed the maximum average biomass content of the samples that used membrane diffuser had higher value of 0.325 g/L when a 1:1 ratio of air and CO2 was used in the feed stream and 0.275 g/L when using pure air as the feed stream. Thus, it has been shown that membrane diffuser is better than a bubble diffuser owing to its larger effective surface area.","PeriodicalId":326334,"journal":{"name":"Journal of Applied Membrane Science & Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129936929","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Compared to other alternatives sources, fuel cell is high at rank as it generates no harmful gases to the surrounding and high in efficiency. The performance of this fuel cell is affected by several factors and one of it is the permeability of proton exchange membrane (PEM). Nafion® is known to be used as the PEM in fuel cells, however due to its high price, polyvinyl alcohol membrane was selected in this study to substitute the Nafion® as it was low in price and excellent in chemical and mechanical strength. Poly (vinyl alcohol) composite membrane was prepared and crosslinked with sulfosuccinic acid (SSA). To further increase the proton conductivity of the membrane, graphene oxide (GO) with 1, 2 and 3 weight percentage was incorporated into the polymer membrane. All the membranes were characterized by using Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), water uptake measurement, contact angle, ion exchange capacity and proton conductivity respectively. Synthesized membranes show low water uptake and contact angle as GO loading was increased. IEC value and water swelling were found to be increased with increasing of GO loading. The proton conductivity of the membrane increases as more GO was incorporated into PVA-SSA and achieved its highest conductivity at 0.020746 S cm-1 with 2 wt. % of GO incorporation.","PeriodicalId":326334,"journal":{"name":"Journal of Applied Membrane Science & Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129783834","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Printing facility provides a wide range of waste component that is harmful to the environment and people. Those harmful waste component contains high concentration of heavy metals and dye. This paper presents one of the most promising methods to remove the heavy metals and dyes from a printing wastewater before discharging to the environment. The feasibility of commercially available NF270 membrane to treat both heavy metals and dye was thoroughly investigated. The study was carried out using a cross-flow nanofiltration membrane system at operating pressure and temperature set at 5 bar and 24 ˚C, respectively. Experimental results showed that the permeate flux of NF270 is decreased from 6.2 to 5.0 L/m2.h after 1-h operation. Whilst, the rejection of both iron and zinc ions could be obtained up to 96.9% and 97.8%, respectively. Additionally, almost complete elimination of colour (99.6%) could be achieved using NF270 membrane. Thus, it can be concluded that the commercial NF270 membrane is promising in removing both heavy metal ions and dye from printing wastewater.","PeriodicalId":326334,"journal":{"name":"Journal of Applied Membrane Science & Technology","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126474181","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, polysulfone (PSf)/ACNF mixed matrix membranes was fabricated using dry/wet inversion technique. The effect of PSf concentration and ACNF loading on the performance of mixed matrix membrane in terms of permeability and selectivity of CO2/CH4 gas separation was observed. The fabricated flat sheet mixed matrix membranes were characterized using Fourier Transform Infrared Spectroscopy (FT-IR) and Scanning Electron Microscopy (SEM) analysis. From the SEM observations, it shows that sponge like structures images were observed upon the addition of ACNFs in the PSf/ACNF membranes was slowly decreased due to increasing weight percentage of ACNF.
