Abstract: A method for circulating hot air in a solar desalination system includes providing a desalination structure having an air flow path defined between an external surface layer and an internal surface layer. A return flow conduit provides an internal fluid flow path. Saline water is pumped through a center column in a direction from the base towards the peak. The saline water is delivered through a nozzle that extends through a sidewall of the center column to provide a mist within the desalination structure exterior of the center column. An air flow within the air flow path is heated to form a hot air supply. The mist is heated with the hot air supply to form an evaporated fluid. A diverted portion of the hot air supply is delivered into the return flow conduit and mixed with an ambient air to form and heat the air flow.

Abstract: A method and system of treatment of agricultural and industrial wastewaters that contain high concentrations of suspended solids, nitrogen, and phosphorus compounds is disclosed. The method and system includes pre-treating the wastewater, controlling the amount of coagulants used, and controlling the mean velocity used for mixing, surface loading rate, and solids loading rate. The method and system functions as a sedimentation unit and gas flotation unit (solid/liquid separator). The pH of the effluent wastewater is stabilized within the separator by ensuring that there is sufficient alkalinity to buffer the wastewater. Sufficient gas is produced in the coagulation reactions to float and concentrate the solids, which results in as high as 99 percent reduction in suspended solids, a 96 percent reduction of the phosphorus concentration, and a 50 percent reduction of the nitrogen concentration in the effluent from the separator.

Abstract: A method of disinfecting or sterilizing an article, such as medical devices or tools, is provided. The items are sterilized by placing them in an enclosed chamber and evacuating the air from the vacuum Ozonated vapor is then injected into the chamber for a predetermined time allowing the ozonated vapor to contact, and destroy, the pathogens in the chamber. The ozonated vapor is injected for a predetermined time and at a predetermined pressure. Upon completion of the disinfection or sterilization cycle, or sub-cycle, the ozonated vapor is evacuated from the chamber by reestablishing a vacuum.

Abstract: A complete water management system employing a plurality of tanks to control the use of potable, gray, and black water. The system is centrally controlled and continuously monitors the condition of all reservoirs, (i.e. the potable, the gray, and the black). The same controller also manages the treatment and interaction between the three reservoirs.

Abstract: An ozone disinfection apparatus is provided whereby the ozone is dispersed in a vapor. The use of an ozonated vapor increases saturation of the article, surface or area being disinfected. Ozone from a generator on-board the apparatus is forced into contact with a fluid, such as water, to form the vapor. Particle size of the vapor is controlled by passing the vapor through an atomizer.
