Decreasing free fatty acid of crude palm oil with polyvinylidene fluoride hollow fiber membranes using a combination of chitosan and glutaraldehyde

Abstract

Crude palm oil (CPO) has emerged as a significant commodity in the economic and social development of producer nations.

Performance of modified hollow fiber membrane silver nanoparticles-zeolites Na–Y/PVDF composite used in membrane bioreactor for industrial wastewater treatment

“…The preparation of dope solutions was modified from previous studies [ 22 , 29 ]. A few zeolite Na–Y or AgNPs/Zeolite Na–Y (0.1, 0.2, 0.3, and 0.4 g) were dissolved in NMP, followed by PVDF dissolution.…”

“…The surface modification by dip coating method offers antifouling and stable mechanical properties [ 21 , 22 ]. The dip coating method coats both sides easier with excellent homogeneity than vacuum methods with similar filtration performance.…”

Performance of a membrane fabricated from high-density polyethylene waste for dye separation in water

“…17 In particular, the membrane process has been widely applied in the dye ltration process, both through the microltration (MF) process to reverse osmosis (RO). [18][19][20][21][22] Nanoltration membranes (NFs) are more commonly used for dye ltration due to their smaller pore size than the MF process. Membranes can be fabricated with a variety of materials from natural to synthesized, such as cellulose acetate, polyvinylidene uoride (PVDf), and polyethersulfone (PES).…”
