A wastewater treatment system includes a circulating fluidized bed evaporator defining a longitudinal axis vertical with respect to gravity. The evaporator has a wastewater inlet to provide wastewater to the circulating fluidized bed evaporator. A heat inlet is axially below the wastewater inlet to provide heat to the circulating fluidized bed evaporator for evaporating the wastewater. An outlet is axially above the wastewater inlet and the heat inlet.

An electrostatic spray dryer for drying liquid into powder including an elongated cylindrical drying chamber having an electrostatic spray nozzle at an upper end and a powder collection vessel at a lower end. The powder collection vessel includes a removable and replaceable filter collections sock made of filter material for receiving and collecting dried powder from the drying chamber. For cleaning residual powder from an inside wall of the drying chamber, a scraper member is provided that is coupled by magnetic attraction to a manually removable driver on the external surface of the wall.

The present invention provides, inter alia, for a liquid feeding device for the generation of droplets, in particular for the use in a process line for the production of freeze-dried particles, with a droplet ejection section for ejecting liquid droplets in an ejection direction, the droplet ejection section comprising at least one inlet port for receiving a liquid to be ejected, a liquid chamber for retaining the liquid, and a nozzle for ejecting the liquid from the liquid chamber to form droplets, wherein the liquid chamber is restricted by a membrane on one side thereof, the membrane being vibratable by an excitation unit, wherein the longitudinal axis of the liquid chamber is tilted relative to the longitudinal axis of the nozzle, and/or the liquid feeding device further comprises a deflection section for separating the droplets from each other by means of at least one gas jet, wherein the deflection section gas jet intersects perpendicular with an ejection path of the liquid ejected from the liquid chamber.

The invention is in the field of devices for producing particles, in particular large agglomerate particles.

An apparatus and method for the distillation of ocean and brackish water that includes a means for using the ambient temperatures of seawater and air to continually transfer the heat energy, from the outer perimeters of the system, back into the, centrally located, evaporation chamber and insulation for preventing heat from escaping to the atmosphere. The insulation comprises a first and second wall surrounding the basic assemblies of a desalination system in which the space between the first and second wall is under low partial vacuum and is partially filled with an insulation material for structural support. The system provides a feed through means that prevent heat transfer through the structural connections between the first and second walls. The system provides an evaporation system for flash evaporation by atomizing the input contaminated water, preheated by the heat of condensation into very small liquid droplets, which are then sprayed into a stream of hot dry air. The liquid rapidly evaporates leaving behind hot dry solids that is recaptured and used to preheat the input contaminated water.
