Title: Procedure and device for improving quality of drinking and bathing water - comprises treating water taken from vessel magnetically and returning in rising curtain flow pattern, and fresh water undergoes vortex and magnetic treatment
Inventor: BROEKER ERNST
IPC: C02F1/44
Filed: 1992-01-27
Abstract: In a new procedure for treating water, a required water column level is maintained in a container, and the water is constantly mixed and moved through a number of vortex paths and is repeatedly exposed to magnetic fields. A part of the water is continuously removed from and is returned to the container under pressure and mixes with the water in the container in the form of a rising curtain. Fresh water enters via an inlet which opens into a conical collector and is conveyed through a vortex zone in which it is exposed to a static magnetic field before passing through a pear-shaped duct to join the water already in the container. This procedure may be repeated a number of times. The water forming the curtain distribution may be returned to the container in a number of small divided vortices. This water enters the container in the same area where the fresh water from the duct enters the water column with a rotating motion. The curtain-distribution water may also be exposed to a magnetic field and/or be enriched with carbon dioxide, as it enters the container, and is taken from a point upstream of the meeting point of the various water flows. Water enters the collector from the rising water column itself and via a number of circumferentially distributed helical or zigzag flow paths from the area of the container which is entered by fresh water coming from the pear-shaped ducts (14). USE/ADVANTAGE - Used for treating water, and especially piped water supplies, in order to improve the biological and therapeutic qualities of the water for drinking and bathing. The treated water provides a more intensive biological and physical healing effect, and allows certain homoeopathic medications, used for therapeutic purposes, to operate more intensively
