A coagulation system is in operative connection with the filter input, wherein the water which has been filtered is subjected to a coagulation process performed by the coagulation system to create pin floc from suspensions in the water. A maturation buffer tank is in operative connection with the coagulation system, wherein floc is aggregated in size within the water. A spiral separator is in operative connection with the maturation buffer tank, and the water is separated into two water streams, a first stream of water having most of the floc removed, and a second stream of water which includes a concentrated amount of the floc. An optional filtration system is in operative connection with the spiral separator and is configured to receive the first stream of water and to perform a filtration operation on the first stream of water. A sterilization system is in operative connection with the optional filtration system and is configured to perform a sterilization operation on the first stream of water. The water is then output from the sterilization system as potable water.

Abstract: An apparatus and method for the photocatalytic conversion of contaminants in a fluid stream. Fluid is directed through a semitransparent packed bed or an open cell, three dimensionally reticulated, fluid permeable, semiconductor unit. Within the unit, a semiconductor, when exposed to a photoactivating light source, converts the contaminants through a photocatalytic reaction. Both the substrate and the semiconductor photocatalyst are semitransparent to the activating light to allow penetration of light into the unit, thereby distributing the light, increasing the active specific surface area, and improving the net conversion performance of the unit.

Abstract: A process for treating an aqueous liquid. The process includes: passing the liquid by force of gravity through a treatment area, the liquid having an upper surface exposed to ambient pressure; disrupting the flow of the liquid as it passes through the treatment area, and exposing the upper surface of the liquid as the flow is disrupted to UV light. Disrupting the flow includes directing lower portions of the liquid toward the surface of the liquid to bring such portions into contact with UV light. A process for treating an aqueous liquid in which the treatment process is monitored. This process includes passing the liquid through a treatment area to bring the liquid into contact with reflective walls submerged below an upper surface of the liquid, and exposing the upper surface of the liquid to light emitted from a UV light source such that UV light penetrates the liquid to strike the submerged reflective surfaces and to be reflected therefrom to emerge through the upper surface of the liquid. The process also involves determining the intensity of the UV light emitted from the light source, determining the intensity of UV light received by a UV light sensor trained to receive emergent light and determining whether the treatment has a predetermined effectiveness based on the intensity of the UV light emitted from the light source and the intensity of the UV light received by the sensor. Apparatuses for carrying out processes of the invention are also described.

Abstract: A humidifier which includes a reservoir of water in fluid communication with an evaporation chamber. Some of the water that enters the evaporation chamber vaporizes and enters the ambient environment. A remainder of the water does not evaporate and flows into a collection container in fluid communication with the reservoir. The unevaporated water is then exposed to a source of ultraviolet radiation which helps to inhibit the ability of various organisms contained therein to reproduce in the future. After irradiation, the unevaporated water travels from the collection container to the reservoir.
