Autonomous sewerage - advantages and varieties

The experience of almost all developed countries shows that the number of people who want to change the stone jungles of megacities to the calm and the dimension of life outside the city is increasing. As a consequence, all the relocating workers create in the new place the same conditions to which they are accustomed.

One of the problems of today is how and how to remove waste from the life of the world's population. Not every homeowner can understand that it is better to spend money not on a gold toilet, but on the simplest system of filtration and waste treatment that merge into the ground. Today, you can count more than twenty different companies that make equipment for sewage treatment in the operation of the house.

If your house is located in the village, it means that there are sewage pipes already laid. It should be noted that in Russia very strict rules and regulations for wastewater treatment, and this is very correct. Many territories in the capital and the region have a superficial soil - clay. It is a layer that absorbs very poorly and allows water to pass through. Therefore, the purified mass of water merges into cuvettes and drains into the nearest water bodies.

Autonomous sewerage - the most important steps in choosing

First you need to find out how many people will live in the house, you can take into account and possible guests. It is estimated that one person uses about 220-250 liters of water per day. If this figure needs to be multiplied by the number of people living, we eventually get a daily sewage capacity. It is necessary to pay attention to the fact that companies issue productivity, counted for the total number of people. This is a serious mistake. Then it turns out that 125 liters per person per day are taken as the norm, and you have purchased a structure that can not cope with the purification of the volumes that will be used.

The second point is the soils near the house. If your house is built on sand, it's not bad - the water will be filtered right into the ground. Provided that the soil is clayey, about 1200 liters of water can be drained into a ditch. This will mean that water after cleaning will flow through the ditches, and the quality of this water should have a high rate of 97% purity.

Classification of wastewater treatment plants

1. Septic tanks. The structure, which is a conventional concrete well of 3 or 4 rings, 1 meter in height or more. At the very bottom of the well, add a series of broken bricks. The degree of possible cleaning with this option is approximately 50%.

2. Installations that clean contaminated water can provide water purification by 96%.

More detailed description

Such a structure as a septic tank has been known for a very long time. We can say more, before this invention was considered an outstanding masterpiece of engineering thought. They constantly undergo processes of decay, decay and sedimentation of larger particles. All lungs rise to the surface, hair, fats, etc., the processes of anaerobic oxidation of the substance occur. Probably all septic tanks consist of several sections. As a result of the occurring ferments and biochemical reactions, a mass of dark color with a bright unique odor emerges. Due to the fact that all this then settles and, as it were, is compressed, the cleaner liquid rises upwards, containing organic and inorganic substances, they are considered active, they give off a pungent smell.

The conclusion is obvious: the water must be cleaned. In our time, firms, bringing the quality of cleaning to the required parameters, are forced to change the design of the septic tank, adding sections and covering them with expanded clay or a specific additive or adding puzolan. This additional section is the so-called drip filter.

It is clear that all these activities make the water more qualitative, although it is still far from these standards. To achieve the required quality of cleaning after all the listed procedures and facilities, filter trenches are used.

Go to the settings for deeper cleaning. Such sewerage is capable of providing purification up to 98%. But the requirements for cleaning are so tough that not everyone can ensure their implementation. More knowledgeable in this matter, the consumer knows only two indicators: BOD, which makes up 3 and 7 mg / l. There are 12 more such indicators, the penalties for the search of which are very different from the BOD. The manufacturer is silent about this, because they are very difficult to remove. Ammonium is obtained from the unmilled ammonia nitrogen .

Biological purification was invented more than a hundred years ago. The classical variant is a sequence of aerobic and anaerobic processes. Less elements - easier technology. It would be necessary to pay attention to the processes of fluid motion between the sections. Optimal in this case, the option - the flow of water.

It is recommended to use this option: the volume of the structure for a family of five or eight people should correspond to a double daily inflow of liquid.
