which improves the soil’s physical character by increasing its capacity to absorb and store water, by enhancement of aeration, and by favouring the activities of lower organisms. Manure incorporated into the topsoil will help prevent erosion from heavy rain and slow down evaporation of water from...
It shows that the value of volumetric oxygen transfer coefficient K1a in airlift is a little higher than that in stirred tank reactor at the aeration rate of 0.1~0.3vvm:the mixing time tm in both of them is small respect to the culture period.The shear stress in stirred tank reactor is...
Average concentrations of 17000 CFU m 3 of mesophilic, 2100 CFU m 3 of TSA-SB bacteria (bacteria associated with certain waterborne virulence factors), 1700 CFU m 3 of mesophilic and 45 CFU m 3 of thermotolerant fungi, were found in the aerosol emitted by the aeration tank of the ...
Very common today is the hang-on-back (HOB) filter. These filters are made to hang on the back of your aquarium, and provide excellent mechanical and biological filtration. They are ideal for use in tanks where space is limited inside the tank, and remove the need for unsightly filters ...
