First, begin
sparging [N.sub.2]/C[O.sub.2] (4: 1 v/v) through the medium at a flow rate of ~25 mL/min.
Nitrogen
sparging and blanketing practices can prevent oxidation in the manufacturing process.
Such dry-air
sparging prevents moisture accumulation within the tank due to atmospheric humidity.
Some products currently integrating porous metal include various implantable devices, filters to prevent plugging of catheters, drug delivery devices, medical instrumentation, various test filters, bacteria filters,
sparging devices for cell culture processing and gas flow restrictor devices for gas delivery in life-critical systems.
Alternatively,
sparging and saturation of the medium with a [CO.sub.2] containing gas can be used.
This tank has been extensively characterized for thickness distribution under direct current plating conditions and compared with commercial plating cell geometries that utilize both eductor flow and/or air
sparging agitation.
7.30am I spend an hour rinsing the malt with a spray of hot water (''
sparging'') and pumping the malty solution, called wort, into the copper.
The contributors focus on applications and real-world examples in their descriptions of fundamental processes as well as in their coverage of reclamation technologies such as physical treatment, including air
sparging and soil heating, chemical treatment, including ion exchange, redox and precipitation, chemical reactive barriers, biodegradation, bioremediation with bacteria and enzymes, including biostimulation and biological fixation, bioremediation with fungi, phytomediation, and metal removal.
The restaurant can offer the service of "
sparging" their open wine to slow its oxidation.
Detailed information about the reactor system and operating procedures (including agitation, gas
sparging, temperature control, and sample removal) has been presented by Schaffer et al.
Rather than
sparging the grain, perhaps they just push a giant cafetiere plunger down on the lauter tun.
