Problems solved by technology

A disadvantage of HDH systems is that conventional HDH units typically have a larger footprint than conventional thermal desalination units that use steam at higher pressures and temperatures with lower specific volumes
Since conventional HDH units operate at lower temperatures, water vapor has a higher specific volume, which requires more vapor space and thus a larger footprint

Abstract

The present disclosure describes a modular humidification-dehumidification (HDH) apparatus and system for concentrating a solution including a plurality of internal modules coupled to each other. The plurality of internal modules includes a humidification module and a dehumidification module in gas flow communication with the humidification module. The humidification module includes humidification media facilitating evaporation of liquid from the solution to gas as the solution passes through the humidification media thereby producing a concentrated solution and a humidified gas. The dehumidification module includes a condensing heat exchanger for condensing vapour from the humidified gas.

Description

technical field [0001] The present invention relates to a modular humidification-dehumidification device for concentrated solutions such as brine. The invention also relates to an HDH system comprising a first effect modular HDH device and a second effect modular HDH device. Background technique [0002] Salt-contaminated water may be unusable or harmful to the environment. For example, mining uses fresh water and discharges waste into ponds. Waste water typically contains about 99.8% fresh water by mass, but due to low levels of salt (eg 0.1% to 0.2% by mass), waste water is unusable. Desalination is being increasingly used in various industries due to regulatory requirements to treat sewage / waste water. Desalination is also used in coastal areas to produce fresh water from seawater, while more brine waste is sent back into the ocean. Reverse osmosis is the main desalination technology, but faces osmotic pressure and scaling limitations, which reduce the fresh water pro...
