Abstract: The integrated aeration system utilizes a water pump for aeration. Ambient air/gas is entrained by a circulating water jet induced by the pump. The circulating water jet enters a sealed tank. The entrained gas is broken into bubbles after the impingement between the jet and a receiving pool occurs, aerating the receiving pool by water jet spray. The entrained gas/air builds up headspace pressure above the water pool, the headspace pressure being measured by a pressure gauge. The trapped air above the water pool is released when the headspace pressure increases to reach a desired value to aerate a separate tank/container as a diffused aeration or any other aeration process.

Abstract: An apparatus for atomizing a precursor liquid for vapor generation and thin film deposition on a substrate. The precursor liquid is atomized by a carrier gas to form a droplet aerosol composed of small precursor liquid droplets suspended in the carrier gas. The droplet aerosol is then heated to form vapor, producing a gas/vapor mixture that can be introduced into a deposition chamber to form thin films on a substrate. The liquid is introduced into the atomizing apparatus in such a manner as to avoid excessive heating that can occur or lead to the formation of undesirable by-products due to material degradation as result of thermal decomposition. The apparatus is particularly suited for vaporizing high molecular weight substances with a low vapor pressure that requires a high vaporization temperature for the liquid to vaporize. The apparatus can also be used to vaporize solid precursors dissolved in a solvent for vaporization.

Another nozzle may be used to introduce a cold fluid at the outlet of the second nozzle for mixing with the hot flow prior to completion of the second deceleration.
