A water purification device comprising a pre-purified water reservoir for storing pre-purified water, a water vapor chamber for receiving water vapor generated from heating the pre-purified water in the pre-purified water reservoir, a condensation chamber for receiving the water vapor and condensing the water vapor into purified water, and a Peltier device comprising a hot side and a cold side. The hot side of the Peltier device heats the pre-purified water into water vapor and the cold side of the Peltier device condenses the water vapor into purified water.

A method and apparatus for water purification and remineralization are disclosed. The apparatus comprises a plurality of thermally coupled thermoelectric modules, as well as means for enhancing mass and energy transfers. The method provides a highly energy-efficient water purification process.

The State of California has been in severe drought conditions yet ironically it is surrounded by oceanwater. Existing desalination systems require expensive electrical power to produce clean potable water. This invention creates its own electrical power input, and even EXTRA ELECTRICAL POWER to supplement California's electrical power grid (part of this inventor's other U.S. patent application Ser. No. 16/598,965.

Desalination and Distillation are two concepts that now belong to public domain and are not owned by anyone. Oceanwater is boiled and salt is left behind, in the process producing clean potable water. Steam is cooled down using cooling coils similar to car radiator, using a blower fan and oceanwater sprinklers.

A dry powder MOCVD vapor source system is disclosed that utilizes a gravimetric powder feeder, a feed rate measurement and feeder control system, an evaporator and a load lock system for continuous operation for thin film production, particularly of REBCO type high temperature superconductor (HTS) tapes.

An automatic tritium extraction device for environmental monitoring comprises a distillation chamber, a temperature control unit, a condensation unit and an auxiliary condensation unit. The distillation chamber is connected to a first pump, a second pump and a third pump. A delivery pipe comprises a first vertical pipe, a second vertical pipe and an oblique pipe which inclines upwards from the distillation chamber to the condensation unit. An automatic tritium extraction method for environmental monitoring comprises the following steps: 1) cleaning of a distillation chamber; 2) distillation rising; 3) distillation; 4) condensation; 5) discharging samples out of the distillation chamber. By the adoption of the automatic tritium extraction device and method for environmental monitoring, fully-automatic distillation and condensation of environmental tritium samples, automatic cleaning of the distillation chamber, and automatic and accurate addition of required agents are realized, and fully-automatic acquisition, preparation, distillation, purification, measurement and analysis of environmental tritium can be completed; and manual intervention is reduced, so that monitoring results are more accurate, and labor costs are saved.

The present invention relates to supercritical water oxidation reactor adapted to contain inside the reactor an aqueous fluid below and above its supercritical state, said fluid comprising organic and/or inorganic material and a method of controlling such a reactor.

A cabinet for a solid material container comprises a main body having a top wall, a side wall, and a bottom wall; an entry/exit portion which is attached to a portion of the main body, for putting in and taking out the solid material container; an exhaust duct attached to a portion of the main body; a heating portion for heating the solid material container; a temperature measuring portion for measuring a temperature of the solid material container, or of the heating portion; and a cooling blower for blowing cooling air toward the solid material container.

In an embodiment, a circuit includes: a transformer defining an inductive footprint within a first layer; a grounded shield bounded by the inductive footprint within a second layer separate from the first layer; and a circuit component bounded by the inductive footprint within a third layer separate from the second layer, wherein: the circuit component is coupled with the transformer through the second layer, and the third layer is separated from the first layer by the second layer.

A microfluidic device may include a first fluid chamber, a second fluid chamber, a first microfluidic passage extending between the first fluid chamber and the second fluid chamber, a second microfluidic passage extending from the second fluid chamber, a first fluid actuator adjacent the first microfluidic passage and proximate the first fluid chamber to inertially pump fluid away from the first fluid chamber and a second fluid actuator adjacent the first microfluidic passage and proximate the second fluid chamber to menially pump fluid towards the first fluid chamber.

A device for converting a liquid into vapor, having an evaporation surface, a liquid inlet, a heater for heating the evaporation surface, a flow controller, a control unit configured to control a liquid flow rate injected into the liquid inlet, a chamber containing the evaporation surface, and a temperature sensor arranged on the evaporation surface. The control unit is configured to control a heating power of the heater according to a flow rate and to a temperature measured by the temperature sensor according to a predetermined control law. The predetermined control law varies, for each flow rate, non-linearly and inversely proportionally to the difference between a reference temperature of the chamber and the measured temperature.
