“…Membrane materials used in algal biotechnologies can be classified into organic and inorganic (Zhang Y. et al, 2019). Polymeric organic materials used in membranes include polyvinylidene fluoride (PVDF) (Marbelia et al, 2018), polyacrylonitrile (PAN) (Marbelia et al, 2016), polyethersulfone (PES) (Yogarathinam et al, 2018), cellulose acetate (CA), polyethylene terephthalate (PET) (Kim et al, 2020;Kusumocahyo et al, 2020;Wu and Sancaktar, 2020), polyvinyl alcohol (PVA), regenerated cellulose (RC), polysulfone (PS) (Ma et al, 2020;Zhao et al, 2021a,b), polyamide (PA), and cellulose ester (CE) (Zhang M. et al, 2019). Inorganic materials, such as ZrO 2 -TiO 2 , are commonly used in ceramic membranes (Low et al, 2016;Hua et al, 2020).…”

The use of algal biotechnologies in the production of biofuels, food, and valuable products has gained momentum in recent years, owing to its distinctive rapid growth and compatibility to be coupled to wastewater treatment in membrane photobioreactors. However, membrane fouling is considered a main drawback that offsets the benefits of algal applications by heavily impacting the operation cost. Several fouling control strategies have been proposed, addressing aspects related to characteristics in the feed water and membranes, operational conditions, and biomass properties. However, the lack of understanding of the mechanisms behind algal biofouling and control challenges the development of cost-effective strategies needed for the long-term operation of membrane photobioreactors. This paper reviews the progress on algal membrane fouling and control strategies. Herein, we summarize information in the composition and characteristics of algal foulants, namely algal organic matter, cells, and transparent exopolymer particles; and review their dynamic responses to modifications in the feedwater, membrane surface, hydrodynamics, and cleaning methods. This review comparatively analyzes (i) efficiency in fouling control or mitigation, (ii) advantages and drawbacks, (iii) technological performance, and (iv) challenges and knowledge gaps. Ultimately, the article provides a primary reference of algal biofouling in membrane-based applications.

“…The membranes were then characterized for their ability to reject macromolecules through ultra ltration experiments using an aqueous phosphate buffered-saline solution containing 1000 ppm BSA. The method to prepare the phosphate buffered-saline solution can be found elsewhere [10]. To determine the rejection R, the following equation was used:…”

“…PEG has been known as a pore forming agent, a pore reducer, and a plasticizer for various polymers [19,20,21]. In this work, low-molecular weight PEG such as PEG 400 was chosen as the additive for the PET membranes since our previous study revealed that the use of high molecular weights of PEG such as PEG 4000 resulted in the membranes with too large pore size that decreased the rejection rate of the membranes [10]. Figure 6 and Fig.…”

“…The source of the polymer material even can be found in used PET bottles or other used PET packaging that are usually considered as waste. In our previous study on the development of ultra ltration membranes using PET bottle waste, it was observed that the permeate uxes increased by decreasing the polarity of the non-solvent, by increasing the molecular weight of the additive, or by increasing the additive concentration [10]. However, it was observed that the permeate ux enhancement was followed by a decline of the rejection rate, because of the enlargement of the membrane pore size.…”

“…Studies on the modi cation of the membranes to improve the permeate ux and the rejection have also been reported [1,8,9]. Recently, our previous study on the use of polyethylene terephthalate (PET) bottles to prepare PET ultra ltration membranes have been reported [10]. PET packaging is widely used by the food and beverage industries because of its excellent mechanical strength, good chemical resistance, good transparency, and excellent gas-barrier resistance.…”

Polyethylene terephthalate (PET) ultrafiltration membranes were prepared using two different sources of polymer material, namely PET bottle waste and PET resin. The membrane prepared from PET bottle waste and that prepared from PET resin showed similar membrane characteristics such as IR spectra, morphology, hydrophilicity and porosity, indicating that instead of using PET resin, PET bottle waste can be utilized as a source of the polymer material to fabricate low-cost membranes. The morphology, hydrophilicity and porosity of the membranes were strongly affected by the additive concentration. The analysis of the membrane morphology using Scanning Electron Microscopy (SEM) showed that the membranes had an asymmetric structure that consists of a macroporous cross section and a smooth active layer. Increasing the additive concentration of polyethylene glycol (PEG 400) resulted in a smaller pore size, however the hydrophilicity and the porosity of the membranes increased. As a result, the membranes showed an increase in both permeate flux and rejection with increasing concentration of PEG 400 as observed from the results of the ultrafiltration experiments. Using Bovine Serum Albumin as a solute model in the feed, high values of rejection of up to 93.9 % were achieved.

Effect of Pollutant Species on the Performance of Chelating Membranes for Wastewater Treatment

et al. 2023

A chelating membrane was fabricated to simultaneously remove metal ions and proteins from simulated wastewater. For a mixture consisting of a single ion and protein, the chelating membrane exhibited overall good separation performance (except for Cd2+), with both ion removal and protein rejection surpassing 90 %. The removal of metal ions highly depends on the chelation of amidoxime groups with ions rather than the complexation of proteins with ions. An increase in the content of metal ions has a detrimental impact on the protein rejection efficiency owing to the damaging effect of heavy metals on the protein. Similarly, increasing the amount of protein adversely affects the removal of ions due to the weakened chelation of amidoxime groups with metal ions.
