AT356018B - DEVICE FOR AERATING GROUND WATER IN THE FOUNTAIN - Google Patents

Description

  

   <Desc / Clms Page number 1>
 



   The invention relates to a device for aeration of water in the well.



   It has long been known to achieve a cleaning or a change in the substances dissolved in the water by aerating water.



   In addition to the precipitation of iron and manganese compounds, which form insoluble, easily separable compounds during aeration, it has also been known for a long time to drive out the dissolved carbonic acid (CO2) in the water, thereby the ratio present in most waters shift from carbonic acid to the existing hardness formers and thereby obtain water which has better qualities (deacidification).



   Such ventilation can also take place in the well from which the water is obtained. DE-OS 2630347 describes a device which serves to enrich well water with oxygen or drives aggressive carbon dioxide out of it. The ventilation takes place in the well itself, the device including an aeration zone to which a removal zone is connected in order to prevent air bubbles from getting into the ring lines of the treated water.



   A static mixing device for intensive contacting of air and water is provided.



  The device according to the invention represents a particularly advantageous construction of a well water aeration device. It has a mechanism by which the aeration and removal zone are arranged in a floating manner in the area of the well water surface, while the water to be supplied to the aeration device is from the deepest base area or from a lower area is removed. The device adapts to the fluctuating level in the well
 EMI1.1
 



   By means of the device according to the invention, groundwater, or well water, even when the water level in the well fluctuates, is adequately aerated when it is removed. Depending on the immersion depth set, the floating device achieves a corresponding oxygen input. Compared to other known devices, the device also has the advantage of particularly low energy, space and construction costs and is particularly suitable for installation in shaft wells.



   On the drawing sheet, a plan view of a device according to the invention is shown above, and below it is an elevation section according to section line A-A in the drawing above.



   As can be seen, the chamber --1-- is designed as an inflow device for the raw water; As a result of the suction gradient, the water flows into the ventilation zone --2-- and flows through the area of the ventilation device --3--, in which air is blown into the flowing medium with fine pores, depending on the setting and requirements. After leaving the ventilation ring --2--, the liquid enters the suction shaft --4--, from where the vented medium is removed in the usual way. The air chamber --5-- enables the system to swim and is stabilized by the stabilizers --6--
 EMI1.2
    --2-- andMantel --8-- enables clean separation of the raw water from the aerated water flow when the water level fluctuates.

   The floor pan - 9 - is preferably arranged on the bottom of the well in the area of the suction effect. The suction pipe is slidably arranged in the upper part of the device, possibly capable of guiding the jacket.



   The suction or pressure pipe --10-- is used to guide the upper part of the device vertically.



  In the case of a single system, this tube must be equipped with two sliding surfaces.

Claims (1)

PATENT CLAIMS: 1. Device for aeration of groundwater in the well, in which the groundwater is passed through an aeration compartment on its way from the inlet zone to the removal zone of the well, EMI1.3 (5) floating aeration ring (2) is formed, which is kept in operation by stabilizers (6) in equilibrium, in which the water due to the suction gradient can be regulated or adjusted by adjusting the swimming height (7) adjustable inlet (1) can be fed in that further <Desc / Clms Page number 2> Bottom area of the aeration ring one or more diffusers (3) for fine-bubble aeration of the flowing water are attached and at the end of the aeration ring there is a discharge opening, which receives the aerated water into a compartment (4) with a height-adjusting function, into which a pump pipe (19) is introduced for the removal of the treated water in the lower region of the compartment (4). EMI2.1 characterized in that the compartment with height-adjusting function (4) by a flexible rubber bellows, or telescopically extending or. retractable walls is formed and that the compartment on the sole is provided with a rust and acid-resistant or PVC (9) pot, this pot being held or fixed at a constant height in the well. 3. Apparatus according to claim 1, d a d u r c hg e k e n n z e i c h n e t that the aeration of the water by a centrifugal fan with an output of max. 0.8 m water column, and EMI2.2 Water ventilation system (diffusers) is completely or partially surrounded at the end of the air supply pipe (3) with a fine-mesh, water-resistant fabric, preferably with metallic fabric. 5. The device according to claim 1, so that the diffusers (3) are arranged horizontally and, if necessary, several, which are arranged in a row, are attached. EMI2.3 Floating body (5) is present, which forms a partial circle and the space left forms a water antechamber (1) in order to keep the well water still and to take it from below the surface. 7. The device according to claim 1, d a d u r c hg e k e n n z e i c h n e t that the device is guided up or down by sliding on the vertically arranged intake manifold. EMI2.4 is only ventilated when water is removed. 9. The device according to claim 1, so that the supporting floating body (5) forms only a partial circle and is additionally stabilized by the stabilizers during operation.
