It is not so difficult to separate water from oil. As the main help in this process serves that water and oil are immiscible liquids. That is various on density and structure so that to carry out their physical hashing, or, speaking to language of science, diffusion, it is possible only at addition of the special substances called emulsifiers. In all other cases water and oil are located in capacity kind of "layers", and oil as lighter substance usually appears from above. Ways to divide them exists a little.
It is required to you
- - freezer,
- - several tanks,
- - household filter for water,
- - activated carbon,
- - rubber tube.
Instruction
1. The simplest and available method in life — a vymorazhivaniye. Used this way even in deep old times. It consists in the following: capacity is cooled to subzero temperature until water freezes. To make it in modern conditions the easiest, having placed it in the freezer. Oil freezing temperature, as a rule, is much lower than temperature of water freezing. After a while water will turn into ice, and oil will remain liquid. It can be merged easily in separate ware, and accurately to wipe the surface of ice for removal of residues of oil with a dry rag.
2. One more simple way — filtering. For this purpose any household filter will approach. However, for a start it is required to merge the most part of oil not to subject the filtering mix to too big loading. After oil is merged, miss water via the filter. There will be it already without oil film.
3. More difficult way — absorption. It is that in the container with water and oil special substance (the so-called absorbing agent) who absorbs alien impurity is located, leaving only water. The most available of such substances is usual activated carbon. However, it is required it very much: take at the rate of three to one rather available oil volume. Place all this in a sealed container and vigorously stir up for an appreciable length of time. You will be able visually to estimate the end of process. If it is required, several times replace ware as a part of oil will inevitably remain on walls. Perhaps, several cycles of loading of the agent will be required. But at the exit you receive clear water without any impurity.
4. And at last, it is possible to arrive absolutely simply. Take the long rubber call. One its end needs to be lowered in the container with water and oil (for convenience it can be recorded an adhesive tape), another — in the ware located on half-meter is lower than this capacity. Attention: the top end of a tube has to be in the very bottom the filled capacity. In advance prepare two more containers: under oil and under intermediate substance. Further everything comes approximately the same as in the course of draining of fuel from a gasoline tank. Podsasyvayete air from the lower end of a tube also you lower it in in advance prepared ware. At once water will begin to be drained. Process needs to be controlled carefully and when water from the top ware flows out almost everything, to quickly transfer a tube to capacity for intermediate substance. Having waited when from a tube oil pours down, substitute the ware intended for oil. If to make everything quickly and correctly, the volume of intermediate substance will be very small, and water and oil, as well as was required, will be poured in two different tanks.
