Description

Centrally supplied water treatment system

The present invention relates to a water purification system, and more particularly, to a centrally supplied water treatment system installed in a large centralized water supply facility, such as an apartment complex, for treating drinking water.

Existing water treatment system is pressurized and fed the water water (CITY WATER) in the water tank 101 to the raw water transfer pump 102, as shown in Figure 1 by the organic activated carbon filter 103 to remove organic matter, taste, smell, detergents, residual chlorine components, etc. After filtration, suspended solids and turbidity components are removed from the micro filter (1μ) 104, and microorganisms and health hazards are removed with a ceramic filter 105 (ultra filter) of 0.2μ, and then supplied to the storage tank 106 for circulation. The pump 107 is used to pass the ultraviolet sterilizer 108 to supply the sterilized treated water back to the storage tank 106.

(The storage tank 106 does not have a separate sterilization device, and thus, there is a problem of inadequate in sterilizing a source of contamination such as various microorganisms introduced into the air layer.)

In addition, the treatment water supplied to the storage tank 106 is composed of a process of supplying each generation to the pressurized water pump system 109, the conventional water treatment system as described above had the following problems.

The ceramic filter 105 has a hassle that needs to be artificially washed (once every 3 days to 4 days) when the differential pressure / treatment water is low before and after, and the activated carbon filter (ACTIVATED CARBON FILTER) is made of granular activated carbon. Since the regeneration process (backwashing (20 minutes) ⇒ settling (5 minutes) ⇒ drainage (10 minutes)) is performed regularly (operated by PLC electric valve of CONTROL PANEL), waste water is discharged from this and the working pressure It was operated at 4.5 kg / cm 2 to 5.5 kg / cm 2, which resulted in large breakage and leakage of the filter material (ACT.CARBON), which provided the cause of lowering the adsorption efficiency.

In addition, since the simultaneous use rate was 15 to 20% or less, there was a shortage of clean water supplied to each generation due to the lack of clean water in the treated water storage tank 106 at the peak.

Hereinafter, the problems of the existing water treatment system will be described in more detail as follows.

The suspended solids, sludge and turbidity components, which are introduced from the storage tank 101 stored in the raw water, are directly filtered through the activated carbon filter 103, thereby rapidly decreasing the lifetime and filtration efficiency of the activated carbon filter once or twice a day. It is necessary to perform a degree of regeneration process, and as time passes, pores of activated carbon are filled, which shortens the lifetime of activated carbon and causes extremely low efficiency.

In addition, the activated carbon filtration device 103 is a granular activated carbon, the installation area is large, the structure is complicated, and waste water is generated during the regeneration of activated carbon, causing waste of resources and environmental pollution.

In addition, the ceramic filter 105 uses a step-down method due to its small flow rate and total filtration, with the disadvantage that it wastes a small amount of waste water when washing the filter once or twice every 3 to 4 days. Therefore, high pressure is applied to the front end of the ceramic filter, which shortens the life and function of the activated carbon filter and the micro filter, causing high risk of defects. In particular, as described above, the flow rate and the total filtration amount are small, so that the step-down method is used. The filter was clogged frequently and had to be cleaned.

On the other hand, the storage tank 106 of drinking water does not have a separate sterilization means, and microorganisms such as bacteria, bacteria, etc. floating in the air in the upper air layer of the storage tank 106 flow into the treated water due to the over-flow, thereby preventing contamination. There was a high possibility of developing a new water treatment system that can correct the above problems is urgently needed.

The present invention is to solve the problems of the above-described conventional water treatment system and to provide a water treatment system having a more efficient water treatment effect,

Not only does it eliminate the need for an artificial filter cleaning, but also reduces the cost of maintenance and initial investment, while also providing easy operation and pursuing economic benefits to increase simultaneous use and reduce investment costs. It is to provide a new water treatment system.
