2015-02-01. Experimental investigations on the vacuum outgassing of a carbon nanotube (CNT) cathode with high-intensity pulsed electron emission on a 2 MeV linear induction accelerator injector are presented. Under the 1.60 MV diode voltage, the CNT cathode could provide 1.67 kA electron beam with the amount of outgassing of about 0.51 PaÂL.DEVELOPMENT OF SUSTAINABLE LAND-BASED List by year the currently approved milestones (indicators of research progress) FY 2005 I.a.

systems. While flow rates in a recirculating water system may actually be higher than in flow-through systems, the lower pumping head saves energy. In flow-through systems, water is pumped from wells as deep as 500 feet. Many wells on fish farms have diameters of 4-6 inches, and pumps often have 5- to 10-horsepower capacities. Recirculating large pp fish tank farm recirculating aquaculture system fFISH FARMING IN RECIRCULATING AQUACULTURE Recirculation aquaculture systems (RAS) represent a new and unique way to farm fish. Instead of the traditional method of growing fish outdoors in open ponds and raceways, this system rears fish at high densities, in indoor tanks with a "controlled" environment. Recirculating systems filter and clean the water for recycling back through fish culture tanks.

In this study, a combined pilot-scale system of down-flow hanging sponge (DHS) reactors and upflow sludge blanket (USB) reactors was applied as a nitrogen removal large pp fish tank farm recirculating aquaculture system f
In order to transport water from filter to fish tanks, centrifugal pumps are used. All pumps are upgraded to the required conditions like temperature and salinity level of the system water. Ozone generator Ozone can play important roles in the prevention and elimination of fish diseases in aquaculture systems.Recirculating Aquaculture Tank Production Systems large pp fish tank farm recirculating aquaculture system fAquaponic systems are recirculating aquaculture systems that incorporate the production of plants without soil. Recirculating systems are designed to raise large quantities of fish in relatively small volumes of water by treating the water to remove toxic waste products and then reusing it.
