Friends, who has a quick way to filter sewage and write the steps and materials to use?. Yes, please let me know! Thank you
Lay the activated carbon on the top floor. Activated carbon is a good filter material, and many water filters use it to filter it. If there is no activated carbon in the field, you can make it yourself. Use wood to make a fire, and then let it burn completely. Fight with soil and gray, with stones or sticks to the charred wood to get the charcoal powder.3. at this point, the filter has been prepared, the sewage poured from the top of the container, so that the sewage can flow through activated carbon, sand, gravel layer. When the water comes out from the bottom, use a clean cup to catch water.4. in the filtration process, the evening news reporter found that the bottom of the cloth more dense, the better the effect of filtration. The first filtered water was not very clear, and after 3 hours of repeated filtering, the researchers found that the water had become very clear. If the water does not look clear or smelly, it can be filtered several times.
Homemade sewage filterTools: cups, mineral water bottles, scissors, cloth, pebbles, sand, dirt, tap water, activated carbonstep1. with a cloth around the bottom cut a good bottle of mineral water, in the cloth below, put a plastic cup, a simple funnel. It is important to note that the cloth gap at one end of the mineral water bottle is not too large. If the gap is larger, the cloth can be folded in two or three layers. Because this cloth is also one of the key factors that can filter effect.2. spread the filter material into the container, the mineral water bottle. The first layer of the bottom is paved with a few centimeters of gravel to prevent sand from flowing out of the bottom of the container. Pour second layers of sand several centimeters thick. Sand is a substance that filters most of the impurities in water. It takes a few centimeters of sand to filter it effectively, so don't put it too little.
The membrane filtration method is the use of a special semipermeable membrane, only water or only pollutants through the membrane method, in order to achieve the separation of pollutants.
