RAINWATER TREATMENT SYSTEMS CLOSED LOOP

Two authors are Nguyen Ngoc Quynh and Vo Hoang Yen Le Workshop.

Quynh said: "today, many people place store, use rain water for daily living, dining. Due to habit and lack of knowledge about the clean water so they had to use rain water eat directly, not through the handle.

Moreover, people in the countryside still tough, hygienic drinking water sources have very high prices ".

From that fact, the construction of rain water treatment system with the steps: handle the smell and color of rain water through the gravel and charcoal; filter filter, reverse osmosis and handle the microorganism by ozone, or SODIS method using energy to treat microorganisms.

Quynh Anh workshop (rightmost) and Hoang Yen next model "precipitation is water treatment systems closed loop".

To have clean water, the children use 2 filter system. Rain water is filtered records in order to remove the dust cloth, large sized impurities (,, …) from the rainwater collection system (roof, gutters, …).

After that was contained in the hot filter containing activated carbon. Rain water away from the tank through activated carbon system will be reducing the smell and color. The water from the tank into the filter system is adjustable valve.

In the second, filter systems for rain water from a container will go through the gravel and charcoal to filter things for under gravity.

Due to this in comments that contain particles of Resin cation absorbed anions (negative ions) have in the rain and then go through a second filter according to the rules of gravity and osmosis.

Rain water after crossing the first filter is absorbed anions will on the second, filter is filter backwards through the bead Resin anion and cation (positive ion) in rain water is absorbed. Then continue through the pipe system into the system handling the microorganisms.

Rain water after deodorant, coloring in the system space, through the first and second filter, will the system handle microorganisms containing air tub ozone. In these places there is no electricity, the use of SODIS measures to destroy microorganisms.

Auditing results of the technical center of quality measurement standards-Department of KH & CN Rabbit shows, the rainwater sample after filtering through all the drinking water standard of the Ministry of health.

Mr. Nguyen Ngoc, instructors remarked: "the subject water treatment systems closed due the children perform very simple, easy to follow, environment-friendly, less expensive (only about 1.6 million if buy more air tub ozôn), high efficiency, can apply for the deep family remote areas, the mountains or the coastal regions ".

Mr. Phan Van hung, local people commented: "I drank rainwater filtered through testing the filtration system of the children, and then, in the very countries, has very pleasant sweetness".
