A standardised, modular mobile water purification unit for the production of safe potable water and for treatment of wastewater is disclosed to fulfil the water need for humans, animals and households. In one embodiment, the unit can be based on a standardized climate-controlled container that is robust both physically and functionally, can be easily transported and quickly set up in remote regions and disaster areas. The unit may work for purification of water of brackish, sea or polluted surface water, and of wastewater, and can be customised to the given water type based on easy changeable treatment modules. The unit includes a rigid frame that can be removed from the container, and also includes a control system for remote monitoring and control of the unit.
Abstract:
The invention describes a new and simple method of construction of a stationary distillation unit and of a small portable distillation unit. The evaporation pans are made of simple materials and are covered with a transparent film. Additionally in the small portable unit its evaporation pan has a double bottom, which receives hot water. By connection of the evaporation pan with the solar collectors its productive ability significantly increases. The portable and stationary desalination units of the invention use solar power exclusively and simultaneously produce two products: distilled water and salt. The exploitation of solar radiation occurs both in the part of the unit covered by the transparent film as well as in the use of hot water produced by the solar collector connected to it, thus speeding up the evaporation of sea water. The transparent film, besides helping increase and hold the heat inside the production space, also protects the production space from pollutants in the environment, and as a result the products do not need further processing before being sent to consumption. Besides the fact that each unit can be used as an autonomous production unit of distilled water and salt, the units can also function as sub-units of a production line of an unlimited number of sub-units, where their combined use functions as a large production unit of distilled water and salt.
Abstract:
The present invention relates to a portable water and climatic production system ("PH2OCP"). In the preferred embodiment, the system utilizes a desiccant rotor wheel to capture water vapor. The desiccant rotor wheel then rotates through a microwave heating chamber to release the water therefrom and heat the airflow as it rehydrates with the water released from the rotor wheel. The heated, moistened airflow then passes through a cooling and condensation system to create air conditioned airflow and water. The "PH2OCP" system is designed to operate and produce water in a wide range of global climatic conditions, including the most arid of environments. This is made possible due to the highly effective performance capabilities of the desiccant rotor technology in the extraction of water vapor molecules from any existing ambient air. The desiccant technology is designed to operate in combination with the microwave reactivation system in the regeneration or reactivation section and cooling coils assembly located in the condensation section.
Abstract:
Systems and methods are disclosed for water collection from atmospheric moisture in large quantities in uncontrolled outdoor environments where the temperature may be cold and humidity levels low. To extract water from air when the dew point is low, a heat exchanger cools to a point where water vapor is deposited on its surface as ice. The heat exchanger then cycles through a heating phase to melt the ice and generate liquid water. The accumulation of frost is advantageous. Frost accumulation enables water collection when the dew point is low. Disclosed variations enhance efficiency and environmental tolerance.

The invention relates to a method for treating demineralized pure water (2) in a device (1) for drinking, and such a device (1), in particular for the treatment of pure water (2) produced from untreated water, wherein treatment materials (5) such as minerals and/or taste enhancers are added to the pure water (2). In order to further improve such a method or device, it is proposed that the treatment material (5) is introduced to the flowing pure water (2) or is added to it by way of the pressure (P) of the pure water (2) itself.

A flexible floating evaporator for solar distillation of water. The preferred embodiment consists of a floating evaporator allowing water to evaporate between 2 isolated outer walls of non-organic materials - the upper transparent and the lower opaque and heat absorbing black. The evaporator is flexible and floats freely according to wind direction and wave movement from a fixation point. The saturated and heated water vapour is from the evaporator pumped to a condenser and distilled water is produced.

The improvements include sensing the ultraviolet (UV) lamp (56) output wavelength to ensure proper operation, bathing the inlet water and outlet water points in the UV light to maintain water sterility, sterilizing air entering the water handling portions of the system, running the condensed water (53) through Teflon tubing (51) to improve sterilization, and sensing the ambient temperature and humidity, and in response controlling operation of the system, for example the power to the condenser, or the blower speed or output volume, to suspend water generation or to maximize efficient water generation, and/or warn the user of a low water production rate.
