“…The short read lengths (400-440 bp) enabled a thorough taxonomic assignment for all samples at the genus level, with an overall low abundance of 1% of unclassified phyla. In comparison to many studies previously conducted on biofouling in water treatment plants (including desalination and waste water treatment plants), biofilm composition in the dairy industry is different, most notably because of the high proportion of Firmicutes, which are absent from water treatment plants (Chen et al 2004;Ivnitsky et al 2007;Huang et al 2008;Matin et al 2011;Khan et al 2013;Levi et al 2016).…”

“…However, concerns around bacterial adhesion warrant further investigation in the dairy industry because of the great resilience of biofilms exposed to cleaning procedures (Tang et al 2009;Hassan et al 2010;Anand et al 2012;Anand and Singh 2013;Anand et al 2014) and the high bacterial counts observed in filtered products (Anand et al 2012). Biofouling, through biofilm development, has been reported in desalination plants (Matin et al 2011;Khan et al 2013;Levi et al 2016) and membrane bioreactors (Ivnitsky et al 2007;Malaeb et al 2013;Vanysacker et al 2014b). Initially, it requires the formation of a conditioning film and the adhesion of specific bacteria (pioneer bacteria) equipped with numerous adhesion strategies (Ivnitsky et al 2007).…”

Few data are available concerning the composition of biofilms found at the surface of filtration membranes, which, to some extent, explains the long-term failure of numerous strategies developed to control biofouling. This preliminary study intended to design a metagenomic tool targeting the 16S rRNA gene in order to unravel a general portrait of bacterial communities found on spiral-wound membranes used in the dairy industry. A total of seven spiral-wound membrane elements (ultrafiltration, nanofiltration, or reverse osmosis) at the end of their useful lifetimes were collected from different dairy plants. Targeted analysis of the 16S rRNA genes of the metagenome extracted from the membranes revealed their bacterial diversity via high-throughput sequencing technology (Miseq, Illumina). It was found that the nature of the filtered fluid (milk, whey, water) explained 58.6 % of the variance observed between communities found on membranes. Treatments applied on dairy fluids (milk pasteurization, whey bleaching or whey ultrafiltration) induced a selective pressure that affected the diversity of bacterial communities found on membranes and the proportions of spore-former bacteria among them. This work provides the first complete bacterial portrait of the biofilm composition of spiral-wound membranes used in the dairy industry. It suggests that the nature of the filtered fluid and potentially filtration Dairy Sci. & Technol. (2017)

“…Fouling and scaling from salt precipitation and biofilm formation affect the overall water flux at the membrane over long periods, resulting in the need for frequent cleaning and turnover of membrane sheets [15]. Furthermore fouling leads to reduced productivity, lower permeate quality, higher energy requirements and treatment costs [16].…”

Current methods of inland concentrate disposal include surface water discharge, deep well injection and evaporation ponds. These methods are unsustainable and are limited by high capital cost and non-ubiquitous application. This paper gives an overview of potential alternatives and technologies available that can reduce the concentrate formed via reducing its volume or recycling. Potential alternatives explored have been electrodialysis, mechanical evaporation, VSEP and WAIV. All technologies have potential for use in areas distant from the coast and have better performance than currents management techniques. This paper reviews multiple studies that have explored alternate technologies for concentrate disposal in terms of economics and feasibility. Of the 5 case studies presented, VSEP shows promise as a secondary system of treatment via enhancing percentage recovery; higher permeate flux and lower operational costs.
