“…Chitosan (beta-(1,4)-2-amino-2-deoxy-d-glucose) is a low cost N-deacetylated product of chitin. Since CS contains active amino groups and hydroxyl groups that can form hydrogen bonds with water, in the past decades, chitosan has been well recognized as a very promising hydrophilic material for pervaporation membranes and construction of functional films [2,3,7,9,[20][21][22][23][24][25][26]. In this paper, the CS complex membranes were formed under a dynamic filtration process.…”

a b s t r a c t a r t i c l e i n f oDuring the past decades, layer-by-layer (LbL) assembly technique based on electrostatic adsorption of oppositely charged polyelectrolytes (PEs) has been one of the most frequently utilized processes for assembling ultra-thin film. However, LbL process is also recognized as a time-consuming process, especially for assembly of dense membranes. In this paper, a one-step dynamic assembly based on electrostatic adsorption was developed to prepare the PE complex membranes. The chitosan (CS), used as a model polycation, was dynamically deposited on a hydrolyzed polyacrylonitrile (PAN) support membrane with negative charges under a selected pressure to form a PE complex membrane for pervaporation separation of water-ethanol mixture. Compared with traditional dip-coating method, this new assembly process could offer some advantages such as the formation of selective layer with dilute solution, easily used for different membrane module types and suitable for large scale applications. The assembly conditions such as dynamic pressure, CS molecular weight, and CS concentration were investigated. The appropriate conditions for assembly were: dynamic pressure, 0.2 MPa; CS molecular weight, 82,000; and CS concentration, 0.5 wt.%. In the case of pervaporation of 95 wt.% ethanol/water mixtures, the separation factor and the permeate flux of the CS polyelectrolyte complex membranes were 422 and 230 g/(m 2 h) (60°C), respectively. The cross-linking treatment with glutaraldehyde and sulfuric acid were subsequently performed. It was found that the separation performance was improved by the cross-linking treatment. Finally, inner skin hollow fiber PE complex membranes were also successfully explored using one-step dynamic assembly for pervaporation dehydration. The proposed process will offer a new approach to obtain a relatively integrated PE complex membrane.

“…PVA is a water soluble polymer and blending chitosan with PVA will increase the water uptake. This is attribute to the increasing of hydrophilic groups (-OH) in the blends (Svangariyaskul et al 2006). It was also found that the stabilities of Chitosan/PVA film are poor in water.…”

“…Akan tetapi, sifat dasar kitosan yang rapuh dan hidroskopis masih menjadi kendala dalam aplikasi filtrasi, sehingga perlu dilakukan formulasi dan optimasi pada komposisi bahan dan proses pembuatan membran. Kitosan dapat dikombinasikan dengan Polyvynil Alcohol (PVA) dan Poly Ethylene Glikol (PEG) untuk membentuk membran kitosan yang hidrofobik dan kuat (Ariyaskul et al 2006;Hyder and Chen 2009;Bolto et al 2009;Zhu et al 2010;Yu et al 2011;Erizal et al 2013;Salehi and Madaeni 2014). Gugus amina pada kitosan akan bereaksi dengan gugus OH-dari PVA melalui ikatan hidrogen sehingga akan memperkuat sifat komposit membran (Riyanto, Suwandi, dan Permana 2010;Lusiana, Siswanta, and Hayashita 2013).…”

Article history PVA (40:60, 45:55, 50:50, 55:45 and 60:40 (v/v)) and stirring speed (200 rpm and 250 rpm). Chitosan composite membrane was tested in a cross flow reactor system. The result showed that the highest rejection values of TSS and TDS generated by the membrane on the chitosan and PVA ratio of 50:50 (v:v) at stirring speed of 250 rpm were 96.84% and 97.23%, respectively. Keywords: Chitosan membrane, POME, Solid rejection, TSS, TDS Kata kunci: AbstrakMembran kitosan POME Penurunan padatan TSS TDS Limbah cair kelapa sawit (LCKS) atau yang lebih dikenal dengan POME merupakan limbah cair industri kelapa sawit dengan kandungan padatan yang tinggi. Filtrasi limbah dengan menggunakan membran kitosan telah diteliti dapat menurunkan nilai padatan pada limbah POME, namun hasil filtrasi masih belum memenuhi baku mutu. Oleh karena itu, perlu dilakukan pengembangan kualitas membran dengan cara formulasi dan optimasi proses pembuatan membran (komposisi dan kecepatan pengadukan). Penelitian ini bertujuan untuk mengetahui pengaruh komposisi dan kecepatan pengadukan terhadap kinerja membran dalam penurunan nilai padatan POME.
