Description

Water treatment system {WATER PURIFICATION SYSTEM}

The present invention relates to a water treatment device, and more particularly, to a water treatment system capable of efficiently filtering foreign substances in supplied raw water and having improved durability of a filter.

With the advancement of industrial activities, various harmful substances are introduced into rivers and lakes, which are major sources of water supply.

In particular, organic salts such as nitrogen and phosphorus and their undecomposed products are continuously accumulated, so self-purification does not proceed. As a result, a large amount of sulfide is generated in sediments deposited at the bottom of lakes, rivers, and seas where eutrophication occurred, Various plankton and green algae that use this as a nutrient source proliferate, deteriorating water quality. In addition, the sediment deposited at a certain height on the floor hinders the smooth flow of water and becomes a factor that increases flood damage during floods.

Therefore, in order to improve water quality, secure quantity, and ensure smooth flow of water, sediment deposited on the bottom of lakes, rivers, and seas is minimized.

In addition, the filtration method is divided into a rapid filtration method and a slow filtration method.

Here, in the rapid filtration method, the raw water supplied is supplied to the rapid filter through a so-called pretreatment process, that is, the injection of coagulant chemicals, rapid mixing, coagulation, and precipitation, and according to the waterworks facility standard, the filtration rate is 120m/day to 150m /Work is standard.

The slow filtration method omits the pretreatment process and supplies raw water directly, but it is standard to adopt a filtration speed of 4m/day to 5m/day.

Accordingly, comparing the rapid filtration method and the slow filtration method, the rapid filtration method has a fast filtration speed, so the suspended matter (SS) penetrates into the depth of the filter bed body, and therefore, when the filter bed is clogged, the backwashing process cleans the sand It goes back to the filtration process.

On the other hand, in the slow filtration method, since the filtration speed is slow, all suspended solids (SS) are collected on the surface of the filter medium, and when filtration is no longer possible due to increased filtration resistance, after draining, the surface of the filter medium is cut about 1 cm. Remove and filter again.

In addition, according to the facility standard, the slow filter paper is rarely used in recent years because the filtering area must be relatively large as a result of adopting a filtration speed of 4 m / day to 5 m / day.

On the other hand, by directly inflowing and purifying raw water without pretreatment, a new improvement plan is required that not only reduces facility installation costs and operating expenses, but also facilitates facility management.

The foregoing technical configuration is a background technology for helping understanding of the present invention, and does not mean the prior art widely known in the technical field to which the present invention belongs.
