Hollow fiber membrane (HFM) technology is one of the main research areas of our group. Our group has built an in-house pilot plant for spinning HFMs using a dry-wet spinning technique. With it, we are preparing new types of HFMs for three main areas: biomedical engineering, water treatment, and gas separation applications. Our research on the HFMs has resulted in several papers and patents.
(1) Hollow fiber membranes for biomedical engineering applications
We are focusing on developing HFMs and substrates based on them for the hemodialysis, bioartificial organ development (Kidney, liver, and pancreas), and mass culture. We have developed novel efficient HFMs for the hemodialysis, which are superior to the commercial dialyzer membranes in terms of biocompatibility and uremic toxins’ clearance performance. The uremic toxins’ clearance is over 5-times better than the commercial dialyzer membranes. No side reactions have been observed with our HFMs. We have also established the protocol for mass production. In addition to this, we are also developing HFM-based bioartificial organs to support organ failure/diseased patients till a suitable donor available. We have developed a lab-scale prototype of an extracorporeal HFM-based unit for the bioartificial kidney application. The unit, in addition to the blood purification, enriches the purified blood with the essential metabolites secreted by the functional kidney cells. We have also made an HFM-based device for the bioartificial pancreas. The device can be placed in the body with pancreatic cells, which secret the insulin hormone in a controlled way. In a month-long lab-scale study, the device helped in controlling diabetes in rats with no signs of side reactions. We have also prepared several HFM-based substrates/constructs for the bioartificial liver application, which support the functional liver cells. A lab-scale liver cell bioreactor has also been developed and tested favorably with goat liver primary cells.
(2) Hollow fiber membranes for water treatment
We are also developing performance-efficient solutions based on nano-enabled HFM technology for the removal of several toxic water contaminants such as endocrine disrupting chemicals, dyes, oil, antibiotics, and phenolic compounds from the contaminated water. In addition to this, efforts are also being directed towards developing efficient HFMs, which simultaneously exhibit both high flux and high flux recovery ratios for the water treatment. We have developed HFMs, which show efficient performance with the practical, real-world example of lake water and municipal wastewater.
(3) Hollow fiber membranes for gas separations
We are developing high-performing HFMs, via incorporating nanoadditives and coating, to address the trade-off between permeability and selectivity, as reported by Robeson for the separation of some commercially significant gas pairs like CO2/CH4, O2/N2, and CO2/N2. Thes e membranes will have applications in biogas concentration for enhancing its calorific value as well as providing low-cost separation technologies.
