A method for circulating hot air in a solar desalination system includes providing a desalination structure having an air flow path defined between an external surface layer and an internal surface layer. A return flow conduit provides an internal fluid flow path. Saline water is pumped through a center column in a direction from the base towards the peak. The saline water is delivered through a nozzle that extends through a sidewall of the center column to provide a mist within the desalination structure exterior of the center column. An air flow within the air flow path is heated to form a hot air supply. The mist is heated with the hot air supply to form an evaporated fluid. A diverted portion of the hot air supply is delivered into the return flow conduit and mixed with an ambient air to form and heat the air flow.

An evaporation system for spray evaporating undesired water comprising: a first pump, a container comprising a sump, a second pump, a spray manifold comprising a spray nozzle, a packing system disposed within the container, a third pump, and an air system comprising an air blower and an air preheater is disclosed. An outlet of a water inlet is connected to an inlet of the first pump. A first portion of a ceiling of the container is constituted by a demister element such that the first portion of the ceiling is entirely configured as an outlet for evaporated water. A second portion of the ceiling is adjacent to an upper edge of a wall of the container. An outlet of the first pump is connected to an inlet of the container. An inlet of a draw line is disposed in the sump; and an outlet of the draw line is connected to an inlet of the second pump. An outlet of the second pump is connected to an inlet of the spray manifold. The spray nozzle discharges water droplets onto the packing system. An inlet of the third pump is connected to an outlet of the sump. An outlet of the third pump is connected to a discharge outlet. The air system is disposed through the wall of the container; and the air system discharges air flow counter to and/or crossways to the water droplets from the spray nozzle. A method of using the evaporation system is also disclosed.

The technology relates to spray dried plasma and methods of making the same. The method includes providing plasma to a spray drying apparatus, spray drying the plasma, at the spray drying apparatus, to form physiologically active plasma powder, the spray drying apparatus configured utilizing one or more parameters, and storing the physiologically active plasma powder.

An atomizing spray dryer employs one or more stages defined by ultrasonic transducers in close proximity to a liquid feed opening forming a path of an atomization flow for producing uniform droplets from a close tolerance with the transducer. The atomization flow exits a gap between the transducer and an outer edge of the opening, such that the passed liquid is responsive to an oscillation of the transducer for forming the droplets. A conical or other suitably shaped transducer engages a substantially round liquid feed opening. Subsequent stages may include a circular, ring, or other suitable shape aligned to receive the atomization flow from a circumference of the conical base, or may also take any suitable shape, preferably to receive droplets directed by the first stage.

A method and apparatus for recovering distilled water from wastewater. The method and apparatus evaporates water vapor from a wastewater stream into a moving airflow, collects collecting distilled water from the water vapor, and powers the moving airflow and the collecting distilled water with a thermoelectric generator. The apparatus includes a self-regenerative distillation unit, with an evaporating channel, a condensing channel, and a distilled water outlet. The thermoelectric generator includes a hot shoe side in combination with the wastewater stream, and a cold shoe side in combination with the distilled water outlet. The thermoelectric generator powers a fan or blower connected to the evaporating channel and/or a water pump connected to the distilled water outlet.
