METHOD AND DEVICE FOR PRODUCING SILICIC WATER BY FILTERING Russian patent published in 2005 - IPC

FIELD: treatment of water.

SUBSTANCE: method comprises filtering tap or natural water from top to bottom through tree layers of stones of natural black silicon of 0.5 cm³ to 3 cm³ grains and supplying and discharging water within 5-15 liters per 6 seconds. The device comprises three same rectangular vessels mounted one above the other and made of biologically inert material, e.g. plastic or stainless steel of 60x30x30 cm (2:1:1) in sizes. The ratio of the vessel volume filled with silicon stones to the volume of the vessel for water is 1:1.5. At the centers of the bottoms of each vessel, within the area of 20x20 cm, are openings of 4 mm in diameter to provide 1 opening per 1 cm². The bottom of each vessel is provided with the funnel. Each of the vessels is provided with the detachable lid which consists of two members and is provided with opening of diameter 2.5 cm at the center. One internal side of each vessel is provided with two projections. One projection is at a distance of 20 cm from the bottom and is used for indicating the level of filling with silicon stones. The second projection is made at a distance of 5 cm from the bottom and is used for indicating the level of water. The bottom of each vessel is provided with funnel with cover. The funnel is made of an inert material.

EFFECT: improved quality of silicic water.
