“…Rejection refers to the solute component which did not penetrate through the membrane. The rejection (R) of solute was calculated based on the equation, R (%) = [1 -Cp/Cr] x 100%, in which Cp is the concentration of solute in permeate, and Cr is the concentration of solute in feed or retentate [31,32]. This difference in rejection is caused by the difference in driving force.…”

Beetroot extract (permeate) fermented by kombucha culture separated through cross-flow microfiltration (CFMF) with pore size 0.15 μm at TMP 2 and 6 bar for 0, 5, 15, 25, and 35 minutes, with a flow rate of 7.5 L/m3.hour, at room temperature potentially serves as a natural energy booster. The research results based on soluble protein show that the optimization process at TMP 2 and 6 bar was achieved at 15 minutes with permeate flux of 32.52 and 28.05 L/m3.h, respectively, and soluble protein content of 0.72 and 0.38 mg/mL, total solids of 3.40% and 3.36%, total sugar of 45.91 and 47.47 mg/mL, and acetic acid of 0.93 and 0.97%. Under these conditions, the CFMF system increased the soluble protein in permeate by 123.53% or 1.23 times, indicating partial rejection, and 22.58% or complete rejection. The identification of amino acids in the optimum condition was dominated by three threonine monomers with molecular weights of 120.11, 120.37, and 120.90 Da (M+), and six tryptophan monomers with molecular weights of 205.11, 205.21, 205.44, 205.60, 205.88, and 205.94 Da (M+). The permeate under optimum conditions had average particle sizes of 2788.0 nm and 2922.0 nm, with particle index of 1.523 and 1.795. The particle distribution in permeate at TMP 2 and 6 bar was less than 10,000 nm in size

“…The authors of [18] proposed a new method to increase rejection in microfiltration by applying membrane oscillation that uses a new type of microfiltration membrane with slotted pores. The oscillations applied to the membrane surface result in reduced membrane fouling and increased separation efficiency.…”

Scale formation is a longstanding and unresolved problem in a number of fields, including power production, petroleum exploration, thermal desalination, and construction. Herein, a high‐temperature scale‐resistant slippery lubricant‐induced surface (HTS‐SLIPS) is developed by one‐step electrodeposition and lubricant infusion. The fractal cauliflower‐like morphology with lubricant oil is conducive to forming an ultralow contact angle hysteresis of ≈1°. The 10‐d real‐world boiling trial indicates that by replacing the uncoated surface with HTS‐SLIPS, the reduction in scale mass is greater than 200% because of the low surface free energy (4.3 mJ m−2) and outstanding smoothness (Ra = 41 ± 8 nm) of HTS‐SLIPS. Thanks to the scale retardation, the bubble departure frequency of HTS‐SLIPS is eightfold higher than that of uncoated surfaces, signifying superior heat transfer efficiency. In these demonstrations, HTS‐SLIPS coated spiral tube exhibits better flowability and lower pressure drop than the uncoated one. In addition, favorable compatibility between HTS‐SLIPS and mechanical vibration is experimentally verified to strengthen the descaling of SLIPS synergistically. It is anticipated that the simple and scalable coating fabrication approach will be applicable in numerous industrial high‐temperature processes where scale formation is encountered.
