A water treatment tank for use with water purification apparatus including an ultra-violet lamp within a bulb onto which incoming water is directed to provide a 360 degree thin laminar flow about the bulb so that all of the incoming water receives the ultra-violet rays even when water is dispensed in a fast refill fashion. The tank may have two compartments, one above the other, formed by a separating baffle. The lower compartment has cooling coils about the walls for cooling the water therein relative to the water in the upper compartment. The ultra-violet lamp and a bulb extends through both compartments and the baffle to purify the water. Each compartment communicates through a conduit to a respective dispensing faucet of the water purification apparatus. The conduit from the upper compartment is a transparent tube formed from polytetrafluorethylene so that the ultra-violet rays act on water within the tube. The bulb in one embodiment is vented at both the top and bottom so that air may circulate around the lamp. In another embodiment the separating baffle is eliminated and the water level within the tank is controlled by a conductivity sensor to ensure that the water within the tank is above the level of the transparent tube so that room temperature water may be dispensed through the tube.

A water purification apparatus and methods for the purification of water are provided. The invention features an atmospherically-isolated, but ventable, reservoir electrolysis cell with control features for selecting an electrolysis duration depending on temperature, time since last electrolysis, or time since last gas venting. The device and associated method can easily take a wide range of input water qualities into account for the production of an effective amount of sterilizing water.

A system for the treatment of water integrating the use of pods. The pods have a sturdy rigid base and a flexible permeable membrane. The tank itself has a viewing port in the sidewall for an observer to witness the treatment process. The tank also has a base with anchor rods for securing the lid. The lid has a monitoring unit and permits the flow of water into and out from the tank. Inserted into the tank is an internal riser tube acting as the return line for the water to the monitoring unit and a directional flow disk. Pods are stacked on top of one another in a predetermined order for the treatment of the water.

A portable, self-contained, fully integrated water purification device which includes a receptacle modified to accommodate a filtration assembly for purifying water, and to store water following purification. The receptacle provides separate openings for water intake, and water outflow. The filtration assembly includes a pump and a multistage filter cartridge. Pump action draws water into the water purification device and forces the water through the multistage filter and into the receptacle. Purified water may be stored in the receptacle until consumption.

A domestic countertop water treatment apparatus comprising a water treatment reservoir which is at least translucent; a housing having an ozone source in flow communication with the water treatment reservoir for treating water in the water treatment reservoir; a carbon block filter and a water pump mounted in the housing, the carbon block filter and the water pump in flow communication with the water treatment reservoir for removing treated water from the water treatment reservoir and passing the treated water through the carbon block filter; and, a treated water reservoir which is at least translucent and is positioned downstream from the carbon block filter for receiving treated water from the carbon block filter whereby, as treated water is dispensed from the water treatment reservoir to the treated water reservoir, the level of water in the water treatment reservoir is visibly lowered while the level of water in the treated water reservoir is visibly raised.
