Turbidity is a numerical expression of the degree of cloudiness of water and measures the degree to which the passage of light is obstructed by suspended substances consisting of organic and inorganic substances mixed in water.

Turbidity (NTU; Nephelometric, February 1999 Ministry of Environment turbidity standard) is an indicator that expresses water quality numerically, and the unit of turbidity in the Korean Industrial Standard is 'degree', indicating the degree of turbidity of water, and a value of 0 degrees is transparent pure water. It means that the larger the number, the more severe the turbidity. Korea's Environmental Agency sets the standard for drinking water as 1 NTU or less (as of February 11, 1999), and in the metropolitan area of Korea, it is known that turbidity is managed at 0.5 NTU or less.

Turbidity (NTU) is a technology that measures the concentration of impurity particles contained in a sample by collecting and measuring the optical signal irradiated to the water sample scattered and reflected by the suspended substance. It is a technique for measuring the concentration of impurity particles in the sample, including surface scattering method, transmitted light measurement method, and scattered light. There are measurement methods, transmitted light and scattered light calculation methods, integrating sphere measurement methods, and particle counting methods, and one method is used depending on low turbidity, high turbidity, ultra-high turbidity, field environment, etc., and the denominator is liter (L), which is a volume value. The molecule is a mass value in milligrams (mg), and the state in which 1 L of water contains a turbidity standard (silicon oxide) as a mass unit of 1 mg is expressed as 1 NTU.

A water pipe cleaning system that recycles washing water, including a second cistern pipe (or saddle fountain or fire hydrant; the following description will focus on the cistern pipe), a recycled washing water supply unit, and a washing water recycling intensive management unit. The operation method includes a preparation process, an installation process, a first washing process, a second washing process, and a water supply process.

On the other hand, in a location where a fire hydrant is installed, the second sperm pipe (or saddle fountain) can be used instead of a fire hydrant, and in the present invention, to simplify the explanation, the second sperm pipe is mainly explained and also , it is quite natural that Haljeongja Hall can be replaced by Saddle Fountain.

The preparation process determines whether the corresponding control signal for washing the water pipe is input by the washing water recycling intensive management unit.

In the installation process, if it is determined that the water pipe is being cleaned in the preparation process, the first and second water valves and each individual water hydrant included in the selected cleaning section are blocked and controlled, and the first sump pipe (or saddle fountain hydrant) is controlled. The second sperm pipe (or saddle fountain or fire hydrant can be replaced if necessary) is fixedly installed and connected to the recycling tank in a watertight state using a cleaning hose.

The first cleaning process is photographed to check the condition of the washing section of the water pipe before cleaning, and the first and second water pipes (or saddle water fountains) and each individual water hydrant and the first water pipe are photographed. After re-checking that the water sump valve and the 2nd water sluice valve are controlled to the blocked state, temporarily open the 1st water sump valve, inject the washing water inside, and continue primary washing and draining until the turbidity falls below 100 NTU. Turbidity can be checked by collecting a portion of the drained washing water and testing the turbidity. In general, 100 NTU may appear to be relatively clear water, but it is known to be unusable as drinking water.

In the second washing process, when the turbidity of the washing water is confirmed to be less than 100 NTU in the first washing process, the first water drain valve is blocked to stop drainage, and the first spermatophore pipe (or saddle sump) and the second spermatozoa pipe (or Saddle fountain) is opened and the recycled washing water supply unit is operated to clean the inside of the water pipe until the turbidity becomes less than 0.5 NTU. The washing water used for cleaning is filtered and disinfected in the recycled washing water supply unit and supplied as washing water for secondary washing. and recycling, so the secondary washing is repeated continuously.

It is known that the 0.5 NTU level of water means that it is safe to drink.

In the second washing process, when the turbidity of the washing water is confirmed to be less than 0.5 NTU, the water supply process is performed between the first sperm pipe (or saddle fountain) and the second sperm pipe (or saddle fountain, or fire hydrant if a fire hydrant is used when necessary). ) is blocked and the inside of the water pipe is photographed to visually check the cleaned state. When it is determined that the cleaning is complete, the first and second water valves and each individual water hydrant are opened to supply water.

The present invention with the above configuration uses water as washing water in the first washing process when washing water pipes, and in the second washing process, the used washing water is recovered, foreign substances and slime are removed and disinfected, and then recycled and used again for washing. This has the advantage of dramatically reducing the waste of precious water resources, minimizing inconvenience to customers by reducing cleaning time, and reducing cleaning costs.

Although the present invention has been described in detail with respect to the disclosed embodiments above, it is clear to those skilled in the art that various changes and modifications are possible within the technical scope of the present invention, and it is natural that such changes and modifications fall within the scope of the appended patent claims.
