Water Treatment Patent

On premise water treatment system and method


A water treatment method uses a removable, disposable cartridge having an internal mesh structure. A disposable heater heats water fed to the cartridge. Precipitated solids collect on the mesh surface provided temperature and residence time are appropriately maintained. The heat breaks down the bicarbonate hardness of the water thereby depositing carbonates on the mesh surface and heavy metals will be codeposited due to the resultant change in pH. The cartridge has a head-space for collecting entrained gases such as volatile organic compounds, chlorine and air. Water sterility is achieved by heating the water over an appropriate period of time. Turbidity is removed within the cartridge due to settling induced by the low fluid velocity controlled by a controller and by a filter provided at the outlet of the cartridge. The filter will become blocked when bicarbonate hardness is carried over forcing a user to replace a spent cartridge. Heat economy and a cool treated water outlet stream are secured by use of a heat exchanger. Water is fed from the cartridge, through an intercooler and the heat exchanger to a storage tank. Water in the storage tank is kept out of contact with air by a movable barrier. Eventually, the water is fed from the storage tank to a dispenser and can subsequently be used in a post-mix beverage dispenser. A visual display indicates the status of the water treatment system.

Waste water treatment method and waste water treatment equipment capable of treating waste water containing fuluorine, nitrogen and organic matter


Waste water containing fluorine, nitrogen and organic matter is treated by introducing the waste water into a water tank filled with calcium carbonate mineral and anaerobic microorganic sludge. An upper portion of the water tank is occupied by the anaerobic microorganic sludge concurrently with natural precipitation of the calcium carbonate mineral toward a lower portion of the water tank. Calcium ions dissolving from the calcium carbonate mineral precipitated in the lower portion of the water tank are made to chemically react with the fluorine in the waste water. At the same time, the organic matter in the waste water is treated by utilizing anaerobic microorganisms in the anaerobic microorganic sludge in the upper portion of the water tank. The nitrogen in the waste water is treated to be reduced by reducibility that the anaerobic microorganisms in the waste water own. There is thus provided the waste water treatment method and waste water treatment equipment capable of treating the waste water containing fluorine, nitrogen and organic matter at low cost without necessitating the organic matter such as methanol as an additional chemical.

Portable water treatment assembly

A portable water treatment assembly and water treatment method are disclosed in which the water to be purified is placed in an upper container together with a suitable bactericide, and is held in that container until the bactericidal action is complete. At that time, an elongate dowel is manually manipulated to open a passage between the upper container and a lower container to drain the purified water through a sediment cartridge in the upper container to remove sediment from the water, and through a cartridge in the lower container containing a medium to remove the bactericide and/or other potentially distasteful ingredients from the water, and the purified water is collected in the lower container for subsequent dispensing and use.
