Abstract

The present invention relates to a uranium removal filter, and more specifically, to purify water in water purification plants, large swimming pools, hotels, resorts, etc. that use groundwater. From July 2021, the National Institute of Environmental Research's drinking water quality test items include natural radioactivity. As the material uranium was additionally designated as an inspection item, the problems of the reverse osmosis filter method, which is a common method of existing uranium removal devices, were solved, and the problems of internal filter media leakage and water pipe leakage due to the installation of water pipes inside the filter tank, which are disadvantages of existing filtration devices, were resolved. We want to solve problems such as distortion.
The present invention is a filtration tank (205) filled with a uranium removal filter (203) made based on titanium dioxide, and water supplied from the water supply unit (200) installed on the top of the filter tank (205). The uranium component of the water contacted and supplied to the uranium removal filter 203 is removed and transported downward by the strainer cap 300, which evenly distributes the water.
The purified water transported downward is transferred from the outside to the inside of the strainer cap 300 mounted on the discharge part 204 installed at the bottom of the filtration tank 205, passes through the discharge outlet 200b, and is transferred to the place of use. Outside the filtration tank (205), there are operation valves (101) (102) (103) (104) that select the water flow of the supply water and a wastewater discharge valve (105) to discharge turbid foreign substances flowing in from the supply water to the outside. It also has an emission function.

Description

Uranium removal filter {DIVICE URANIUM REMOVAL FILTER}

[ 0001 ] The present invention relates to a uranium removal filter, and more specifically, to a uranium removal filter capable of removing uranium components contained in source water in all places where groundwater is used.

[ 0002 ] Among the contaminants detected in groundwater in some areas of the country, the risk of uranium content is becoming more serious day by day.

[ 0003 ] From July 2021, uranium, a naturally radioactive material, has been additionally designated as a test item in the drinking water quality test items of the National Institute of Environmental Research.

[ 0004 ] Naturally radioactive materials are about 40 types of elements that exist in nature, including uranium and radium, with high atomic numbers, and emit radiation when their atomic nuclei decay.

[ 0005 ] The Ministry of Environment conducted a survey on the content of uranium in groundwater nationwide from 2007 to 2010, and found that in some areas, uranium concentration exceeded the U.S. drinking water quality standard (30㎍/L), which resulted in the use of domestic groundwater and spring water. Uranium component was additionally designated as a test item.

[ 0006 ] Although the concentration of uranium in drinking water is low, it is known to be a kidney toxic substance and has a long half-life, making it difficult to naturally decrease.

[ 0007 ] Accordingly, starting from July 2021, uranium, a naturally radioactive material, has been added to the drinking water quality test items of the National Institute of Environmental Research, and the designated test standard has been set to be within (30㎍/L).

[ 0008 ] Conventional water treatment technology for such uranium contamination includes a technology for removing it using a reverse osmosis filter.

[ 0009 ] A reverse osmosis filter type water treatment device uses a high-pressure pump to pass supply water containing contaminants through a fine filtration membrane (0.0001 micron), and the water is divided into pollutants and contaminant-free water.

[ 0010 ] The disadvantage of such a reverse osmosis filter is that only 50% of the supplied water is used as purified water, and the remaining 50% of the water is discarded as wastewater. In addition, discarded wastewater must go through a separate wastewater treatment process to be discharged as water that meets normal wastewater treatment standards.

[ 0011 ] In addition, initial facility investment costs are high, and maintenance costs are also significant.

[ 0012 ] Accordingly, there was a need for a stable and effective uranium removal device that would solve the shortcomings of existing commercialized reverse osmosis filters.

[ 0013 ] The present invention was created to improve the problems of the prior art. When feed water containing uranium components is supplied into the filter, it is transferred to the uranium removal filter and after sufficient contact with the uranium removal filter, the uranium component is removed. The purpose of the present invention is to stably supply water to users.

[ 0014 ] In order to achieve this purpose, a device according to the present invention is also provided to selectively change the flow direction of the feed water and discharge turbid contaminants inside the uranium removal filter to the outside. In addition, the conventional filter is a device that has an inlet and an outlet located at the top of the filter tank, so filtration efficiency is low and there is an inconvenience in that the filter material flows out when the internal water pipe is damaged during backwashing.

[ 0015 ] The uranium removal filter according to the present invention is a uranium removal filter for effectively removing the uranium component contained in the feed water, and is a filtration tank into which a uranium removal filter made based on titanium dioxide component is inserted.

[ 0016 ] A water supply unit containing a strainer cap (STAINER CAP) that transfers externally supplied water to the filtration tank and effectively contacts the uranium removal filter made based on titanium dioxide.

[ 0017 ] After passing through the water supply unit, it falls into the internal space of the filtration tank and passes through a uranium removal filter unit made based on titanium dioxide to remove the uranium component.

[ 0018 ] A discharge unit containing a strainer cap (STAINER CAP) installed at the bottom to transport the supply water from which the uranium component has been removed after passing the uranium removal filter unit to the point of use.

[ 0020 ] Operating valve for selecting the water supply direction of the water supply and discharge parts

[ 0021 ] A wastewater discharge valve that discharges turbid foreign substances to the outside using the operation valve.

[ 0022 ] The uranium removal filter according to the present invention inserts a uranium removal filter made based on titanium dioxide inside the tank, and when source water is supplied, the uranium content contained in the input source water necessarily comes into contact with the uranium removal filter. After the uranium content has been clearly removed from the feed water, clean feed water can be transported to the place of use through the lower discharge section.

[ 0023 ] The water flow can be changed using the operation valve installed in the drain part outside the water supply part, and the turbid contaminants collected inside the uranium removal filter can be discharged to the outside.

[ 0024 ] The present invention has the effect of solving the excessive initial installation and maintenance costs, which are the disadvantages of existing reverse osmosis devices, while increasing the uranium removal effect.

Using a uranium removal filter effectively removes turbid foreign substances in the feed water, reduces costs due to periodic replacement of filters, which is a disadvantage of existing reverse osmosis devices, and reduces environmental pollution caused by discarded filters after use. In particular, the biggest disadvantage of reverse osmosis devices is that The problem with the recovery rate (50%) of phosphorus purified water used can also be solved. The water treatment recovery rate of the uranium removal filter is (95%). In other words, there is no wasted water other than the washing water (5%) of the uranium removal filter. In addition, there is no need to install a water pipe inside the filtration tank, preventing external leakage of the internal uranium removal filter, and installing a cap on the strainer improves filtration efficiency and backwashing efficiency. This rises.
