Description

Simplicity clean water treatment apparatus

The present invention relates to a simple water purifying apparatus, and more particularly to a simple water purifying apparatus for purifying contaminated water by drinking water without requiring a power facility.

Worldwide, interest in water is increasing. The UN study reports that in 2025 a third of the world's population will suffer from water shortages.

In particular, countries with severe water shortages are Africa, the Middle East, and Southeast Asia. In these countries, drinking water is polluted because they can not obtain clean drinking water, and people are suffering from waterborne diseases.

In other words, if there is a shortage of water to be used, priority is given to securing the village waterworks (simple waterworks) through groundwater development, but in the case of the underdeveloped countries, it is not easy to solve even the village waterworks due to equipment and cost problems.

Therefore, low cost, high efficiency drinking water source development and water treatment technology is indispensable as a last resort to cope with global water shortages. In particular, the problems that can be directly affected by the residents of the village waterworks that use underground water are the ways to purify polluted drinking water.

In general, village waterworks take chlorine disinfection to collect groundwater from a reservoir and store it in a reservoir tank, and to solve the water quality problem of bacteria in the reservoir tank. However, automatic chlorine dispensing apparatus for chlorine disinfection, It is not possible to install it in places and it requires a lot of operation cost.

Specifically, conventional technologies related thereto include a technology using a domestic small-sized water purification system described in Patent Document 1 or a water purification technology utilizing a photocatalyst described in Patent Document 2, but the installation and maintenance costs are basically expensive, And there is a problem that economical efficiency is deteriorated due to frequent breakdown of an accessory device such as an automatic chlorine dispenser and high power cost.

Particularly, such a purified water system can not be downsized, which raises the cost of manufacturing the system, and it is difficult to move and install the water purification system easily in an area where the water purification is required because the installation can not be carried out.
