In 1998, Rochem Group licensed the technology to Pall Corporation (Pall). Prior to 1998, the license for the U.S. Disc Tube market was held by Rochem Environmental, Inc. According to the vendor, the technology has been used successfully in more than 900 European and U.S. petroleum-related applications. Between 1989 and 1995, Disc Tube systems were used to treat landfill leachate at over 30 European landfills. 

Pall Corporation owns and operates a Disc Tube system at the BFI Conestoga Landfill in Morgantown, Pennsylvania. According to Pall, the treatment costs to the landfill s owner are less than 0.08/gal of leachate treated (D23021X, pp. 43-45).

O. 2-pm CritiCap Supor capsule filter (Pall Corporation) into the 1-1 polycarbonate bottle under class-100 filtered air. Subsamples of this 0.2-pm filtered station B seawater were collected for subsequent iron measurements, which confirmed that dissolved Fe concentrations were relatively low (0.17 0.1 nM, n = 4). Based on the concentrations of FeCl3 (11.65 pM) and EDTA (11.71 pM) in the LI medium, the resultant 1-1 inoculum of colonial P. antarctica had initial dissolved Fe and EDTA concentrations of approximately 1.42 and 1.25 nM, respectively. 

Diisopropylethylamine (sequenal grade), trifluoroacetic add (sequenal grade), and 1,3-dicydohexylcarbodiimide (DCC) were obtained from Pierce. The carboxylic add modified polyethylene membranes were from the Pall Corporation (Long Island, NY). Zitex G-110 was from Norton Performance Plastics (Wayne, NJ). The amino acid thiohydantoins used in this study were synthesized as described (9). The Reliasil HPLC columns used in this study were obtained from Column Engineering (Ontario, CA).

Another example of CMF equipment used for tank bottom recovery is the Keraflux beer recovery system produced by Pall Corporation. Keraflux systems are available both as a batch version and as a continuous version, the latter being used for larger processing capacities. Other types of membrane systems have also been used for this purpose [47] but the tubular ceramic membrane systems are the current state of the art. 

Besides its direct use in the final product, water is used in breweries as a utility, for purposes such as cleaning, steam generation, etc. Another common utility in breweries are gases, such as air and carbon dioxide, which sometimes might contain impurities that need to be removed in order to ensure the quality and uniformity of the hnal product. Besides traditional methods, i.e., activated coal treatment, purification of utihties can also be successfully done by membrane filtration. Some membrane manufacturers (i.e., Pall Corporation, Donaldson Ultrafilter Inc., Sartorius, Millipore, CPM, etc.) offer commercial membrane separation equipment that is specihcaUy designed for the purification of water, steam, air, or carbon dioxide. This enables breweries to produce sterile and particle-free utihties for the brewing processes.

To compare the performance of the three yeast species and to prevent growth limitations due to any nutritional deficiency, the BSG hydrolyzate was supplemented with several mineral nutrients and vitamins to reach the concentrations described in Duarte et al. [17], D. hansenii biomass production for subsequent studies was carried out using a previously optimized medium containing 0.5 g F KH2PO4 as the only supplement to BSG hydrolyzate [2]. To prevent nutrient thermal decomposition, all media were filter sterilized using a 0.22-pm Gelman membrane filters (Pall Corporation, Arm Arbor, MI, USA).

Second, a diffusion barrier layer is usually required to prevent intermetallic diffusion between the Pd alloy fllm and the stainless steel support. A strategy used by Pall Corporation to mitigate both of these issues is to deposit an oxide coating on the stainless steel Alter as shown in Fig. 12.4. This creates a diffusion barrier and reduces the surface roughness of the substrate.
