“…MFM technique is a versatile technology for water and wastewater treatment, and it is estimated that the application of different membranes for MPs removal will increase in the following years (Li et al 2018;Poerio et al 2019;Chuanwen et al 2020;Lorain et al 2020 in the effluent of the system. Thus, MFM could remove the MPs by up to 98%.…”

In this research, the fate and removal of microplastics (MPs) entering and leaving in wastewater treatment plant (WWTP) was investigated. Additionally, the application of microfiltration membrane technique for MPs removal were evaluated. In the first phase, the quantity, type and size of the MPs were studied from three different points of the WWTP. The results showed that the average amount of MPs entered into the WWTP, accumulated in thesludge matrix and discharged from the effluent were 206, 183 and 94 MP/L, respectively. The MPs were observed mainly in the forms of fiber, pellet, and fragment, with a proportion of 35%, 39, 22, and 34%, 22, 38, and 31%, 39%, 37.7% in the influent, effluent and sludge of the WWTP, respectively. It should be noted, a minor amount of foam (2%) and film (0.3%) was also observed. The particle size distribution of the MPs in the effluent of the system was almost identical (6–14% for 1–5,000 μm), while the influent mostly contained the particles within 1–100 μm (above 26%) with other particle sizes within 100–5,000 μm (8–17%). Particle size within a range of 500–5,000 μm was abundant in the sludge. In the second phase, a micro-filtration (MF) membrane with a pore size of 0.1 μm was applied to eliminate the MPs from the effluent of WWTP. It was observed the application of MF membrane technique could achieve MPs removal efficiency up to 98% in the effluent of the system.

“…UF membranes, most commonly used in biotechnological applications [ 16 ], are usually made of ceramic or polymeric materials such as polysulfone (PS), polyethersulfone (PES), polyvinylidene difluoride (PVDF), aromatic polyamide (PA), cellulose acetate (CA), etc. [ 11 , 15 , 17 ]. Whilst ceramic membranes are more robust in terms of resistance to fouling, chemical compatibility, and thermal stability (i.e., during the sterilization process), their use remains limited to niche applications, primarily due to their relatively high cost compared to polymeric membranes [ 18 ].…”

The Effect of Heat Sterilization on Key Filtration Performance Parameters of a Commercial Polymeric (PVDF) Hollow-Fiber Ultrafiltration Membrane

Membrane processes can be integrated with fermentation for the selective separation of the products from the fermentation broth. Sterilization with saturated steam under pressure is the most widely used method; however, data concerning heat sterilization applicability to polymeric ultrafiltration (UF) membranes are scarcely available. In this study, the effect of the sterilization process on the filtration performance of a commercial polyvinylidene difluoride (PVDF) hollow fiber UF membrane was evaluated. Membrane modules were constructed and sterilized several times in an autoclave. Pure water flux tests were performed, to assess the effect of heat sterilization on the membrane’s pure water permeance. Dextran rejection tests were performed for the characterization of membrane typical pore size and its fouling propensity. Filtration performance was also assessed by conducting filtration tests with real fermentation broth. After repeated sterilization cycles, pure water permeance remained quite constant, varying between approx. 830 and 990 L·m−2·h−1·bar−1, while the molecular weight cut-off (MWCO) was estimated to be in the range of 31.5–98.0 kDa. Regarding fouling behavior, the trans-membrane pressure increase rate was stable and quite low (between 0.5 and 7.0 mbar/min). The results suggest that commercial PVDF UF membranes are a viable alternative to high-cost ceramic UF membranes for fermentation processes that require heat sterilization.
