“…Such device should be representative for conventionally used membrane modules, thus involving the used materials (properties and structure) such as membrane and spacer, the height of the flow channels and hydraulics. The membrane fouling simulator (MFS) was introduced in 2006 [4] and since then many articles have appeared on various research aspects of biofilm characterization [2,3,[27][28][29][30][31][32][33][34][35][36], biofouling control [5,[37][38][39][40][41][42][43][44][45][46][47][48][49], and strategies for early warning of biofouling [50][51][52][53][54][55] applying the developed MFS.…”

“…Studies with phosphorus or phosphate limitation of microbial growth were observed for wastewater, rivers, surface and seawater, and drinking water [64][65][66][67][68][69][70][71][72][73][74][75]. Recently, biofouling control by phosphate limitation has been demonstrated for membrane systems [42][43][44]. The common molar ratio for carbon (C), nitrogen (N) and phosphorus (P) in microbial biomass is ~100:20:1.7 [76].…”

“…Feed spacers have been shown to have a strong impact on biofouling [46]. MFS studies have been performed to evaluate feed spacers (i) as applied in practice, including varying spacer thickness [37], (ii) after modifications by hydrophilic, amphiphilic bactericidal and biocidal coatings [38,39,42], and with innovative geometries [29,44,48,86,87]. A novel strategy for a cost-effective development and evaluation of feed spacers was developed for biofouling and scaling control involving (i) numerical modeling, (ii) three-dimensional (3D) printing of spacers, and (iii) MFS testing of hydrodynamics and biofouling impact [43].…”

DESALINATION AND WATER TREATMENT 126: 1-23. Available: http://dx. a b s t r a c tThe growing demand for fresh water has resulted in increasing use of reverse osmosis (RO) membrane systems for seawater desalination. A major operational problem of RO membrane filtration systems is biofouling -biomass growth causing an unacceptable membrane performance decline. Biofouling reduces the produced water quantity and quality and increases costs. The need for fouling remediation is mainly derived from destructive trial-and-error research with practical membrane modules. Therefore, a clear need existed for the development of a small-sized membrane fouling simulator (MFS) for systematic, low-cost studies. Since the introduction of the MFS in 2006, many articles have appeared which are evaluated in this review. The review describes (i) the location of biofouling in full-scale installations, (ii) development of MFS, (iii) characterization, reproducibility and representativeness of fouling development in the MFS, (iv) applications such as assessing the impact of anti-scalant or biocide dosage, phosphate limitation, feed spacer geometry and linear flow velocity and (v) early warning for biofouling. MFS studies have increased the understanding of biofouling and enabled improved practical membrane performance such as selection of dosed chemicals and feed spacer design. Future MFS studies are anticipated to enable the development of advanced biofouling control strategies.
