Most membranes can be sterilized if needed. Application. Guide To Select Membrane.
Meat rendering operations produce stick water waste which is rich in proteins, fats, and minerals. Membrane distillation (MD) may further recover water and valuable solids, but hydrophobic membranes are contaminated by the fats. Here, commercial hydrophobic polytetrafluorethylene (PTFE) membranes with a hydrophilic polyurethane surface layer (PU-PTFE) are used for the first time for direct
2019/8/8 · The membrane consists of a stretched PTFE layer on a polypropylene (PP) backing structure (Fig. 1). It rejects liquid water due to its nonpolar surface properties, whereas steam can pass the membrane pores. Typical pore sizes are between 0.1 and 0.5 μm
suspension was then filtered through a 0.45-lm PTFE membrane and the isolated cell solids were extracted again 1372 J Am Oil Chem Soc (2012) 89:1371–1381 123 with a
2010/7/29 · In this paper, the direct coupling between stir membrane extraction and infrared spectroscopy working under transmission mode is presented for the sensitive and selective determination of the total hydrocarbon index in Aijiren Technology. For this purpose, a new extraction unit was built using stainless steel in order to maximize the adsorption of the target analytes in the 40-μm-thick

The evaporation of the liquid stream takes place on one side of the membrane, and mass transfer occurs through the vapor phase inside the membrane. The role of operative conditions on the process performance is widely investigated in the case of dilute binary aqueous mixtures containing acetone, ethanol, isopropanol, ethylacetate, methylacetate, or methylterbutyl ether.
The MD membrane acts neither as a sieve nor in differentiating between solution composition concentrations. Because of this, such membranes can be made from chemically resistant polymers like PTFE, PP and PVDF, and have large diameter pores that are).

(Millipore Corp., Madrid, Spain) with PTFE tape membrane (100 μm in thickness and 0.5 μm of normal pore size) in order to recover MWCNTs after extraction. The elution process was carried out inside an ultrasonic bath (model 3510, Branson, Danbury, CT
PTFE membranes are particularly suitable for preparing samples for HPLC analysis. The hydrophobic nature of the membrane also has applications for air and gas sterilization. The membrane is laminated onto a nonwoven polypropylene support web for improved strength and handling and can be used at temperatures up to 120ºC.

2005/9/7 · A new method for extracting dissolved gases in natural Aijiren Technology has been developed and tested, both in the laboratory and in the field. The sampling device consists of a polytetrafluroethylene (PTFE) [13] Gas transport through a dense nonporous membrane, such as PTFE, can be described by the Solution-Diffusion Model [Barrer, 1934; Van Amerongen, 1946; Wijmans and Baker, 1995], …
