A water purification system utilizes an ionomer membrane and mild vacuum to draw water from source water through the membrane. A water source may be salt water or a contaminated water source. The water drawn through the membrane passes across the condenser chamber to a condenser surface where it is condensed into purified water. The condenser surface may be metal or any other suitable surface and may be flat or pleated. In addition, the condenser surface may be maintained at a lower temperature than the water on the water source side of the membrane. The ionomer membrane may be configured in a cartridge, a pleated or flat plate configuration. A latent heat loop may be configured to carry the latent heat of vaporization from the condenser back to the water source side of the ionomer membrane. The source water may be heated by a solar water heater.

The invention relates an evaporator. The evaporator may include a drum. The drum may have a first portion and a second portion. The drum may include a product inlet positioned at the first portion of the drum, a product outlet positioned at the second portion of the drum, a vapor outlet, and an agitator. The evaporator may have a heating jacket and/or a product supply pipe. The heating jacket may be configured to surround the drum and/or to heat the product in the drum. The product supply pipe may be positioned outside the drum and/or may extend from the second portion of the drum to the product inlet positioned at the first portion of the drum. The product supply pipe may be in direct contact with the heating jacket.

A system is disclosed for drying a material to liberate a substance such as a liquid having a vapor pressure from solids and/or dissolved substances in the material. The system includes a plenum chamber and a blower providing a stream of air to the plenum chamber. An outlet communicates with the plenum chamber and a velocity accelerator is disposed downstream of the outlet. The velocity accelerator is arranged to receive air from the outlet of the plenum chamber into a progressively narrowing interior passageway terminating at a downstream choke point orifice. The choke point orifice discharges into a larger diameter discharge region. A throttle body is disposed in the discharge region and is selectively movable toward and away from the choke point orifice to decrease or increase the volume of the discharge region. A passageway is formed through the throttle body for receiving flashed material from the discharge region and conveying the material in a downstream direction. Also disclosed is a system for drying materials contained within a processing vessel wherein flash generators with vacuum throttles are used to maintain drying conditions within the vessel and to remove liberated substance from the processing vessel.

The present invention relates to an effluent liquid evaporator (100) to treat wastewater by increasing the evaporation rate with easy and automatic cleaning in an economical manner. The effluent liquid evaporator (100) comprises a pan module (101), a fan module (102), a set of sensors (103) and an injection unit (104). The injection unit (104) is configured to inject a controlled amount of effluent in said pan module (101). The pan module (101) include a plurality of stack of pans (105) to retains the desired amount of effluent to be heated via solar energy which results in evaporation of the effluent. The fan module (102) provides a direct and balanced airflow and facilitates rapid evaporation leaving behind a residue. The set of sensors (103) are configured to perform closing and opening operation on a set of vents for mixing fresh air with a humid air for increasing an evaporation rate of the pre-defined amount of effluent.

A gravity power and desalination technology system is provided, including a heat storage apparatus, an inner tube portion, a hot-air and vapor generator, and venting holes, a corrugated tube portion, an outer tube portion, an updraft wind power generator, and an artificial hydro power generator. The heat storage apparatus is provided in a lower portion and configured. The inner tube portion has an inner vent portion inside and disposed vertically over the heat storage apparatus. The hot-air and vapor generator is disposed between the heat storage apparatus and the inner tube portion. The venting holes are bored through the inner tube portion obliquely outwards. The corrugated tube portion is provided on a top portion of the outer tube portion. The updraft wind power generator and the artificial hydro power generator are installed in the lower portions of the inner vent portion and the outer vent portion, respectively.

A depositing arrangement for evaporation of a material including an alkali metal or alkaline earth metal, and for deposition of the material on a substrate is described. The depositing arrangement includes a first chamber configured for liquefying the material, wherein the first chamber comprises a gas inlet configured for inlet of a gas in the first chamber, an evaporation zone configured for vaporizing the liquefied material, a line providing a fluid communication between the first chamber and the evaporation zone for the liquefied material, wherein the line includes a first portion defining a flow resistance of the line, a valve configured for controlling the flow rate of the gas in the first chamber for controlling a flow rate of the liquefied material through the line having said flow resistance, and one or more outlets for directing the vaporized material towards the substrate.

An aerobic treatment system is disclosed herein in which an aerobic holding treatment tank, having an inlet adapted to receive wastewater and an outlet adapted to discharge treated wastewater therefrom, is in communication with an aeration pump having an inlet nozzle in communication with the aerobic holding treatment tank for providing a source of air to the contents of the aerobic holding treatment tank. The aerobic treatment system may further include a generation pump disposed below ground level and in fluid communication with the aerobic holding treatment tank.
