Bacteria for septic tanks – another way to treat wastewater

Bacteria for septic tanks

Are we wondering how many household appliances in our house that consume water, how much water we use to meet our daily needs? This issue is especially relevant in country houses, where there are several bathrooms, a bathroom, a kitchen, a washing machine, etc. The operation of all devices leads to a completely logical question of where to put the wastewater afterwards. And then a septic tank comes to the rescue, which is a facility for the treatment of fecal matter and domestic wastewater. Special bacteria for septic tanks are used for water purification..

The principle of using bacteria to clean

Bacteria used for septic tanks are living microorganisms that require wastewater to feed. This food must be constant, otherwise, when the cleaning device is operated irregularly, the bacteria die. Under such circumstances, wastewater treatment does not occur. Special biologics may become a solution to the problem..

Living microorganisms allow the processing of organic deposits, fats and wastes that were obtained naturally. The selection of bacteria is carried out depending on the treatment plant. The undoubted advantage of such biological products is not only a fairly quick waste treatment, but also the elimination of their unpleasant odor.

The manufacture of biological products based on bacteria for treatment plants is carried out only from natural materials that are completely decomposed. This allows you to not harm the environment, since biological substances do not contain any toxic elements..

Microorganisms process organic matter into compounds such as water, carbon dioxide and various salts. This biological method of wastewater treatment today is one of the most effective and affordable for domestic use..

The result of using bacteria for the septic tank is:

  • Destruction of fatty deposits from the walls of the treatment plant.
  • Liquefaction of sediment at the bottom of a septic tank.
  • Faster decomposition of organic waste.
  • Elimination of various blockages.

The main principle of water treatment in septic tanks

Today on the Internet you can get a lot of information about bacteria for septic tanks: consumer reviews, types, manufacturers of biological products, etc..

Types of “biological weapons”

One or another type of septic tank determines the type of bacteria used, which can be aerobic or anaerobic. The fact that unites these two types of bacteria is that the microorganisms that compose them are living creatures, which must be provided with appropriate and necessary conditions for life. The fact is that they can be destroyed by a number of chemicals, despite all the unpretentiousness. So, household cleaners can have a negative effect and kill bacteria, for which, in particular, chlorine and formaldehyde are dangerous.

Aerobic bacteria for septic tanks

Translated from the Greek language, the word “aerobes” is translated as “air” or “life”. It is customary to attribute microorganisms to the group of aerobic bacteria, the basis of the vital activity of which is oxygen. That is why, to create the necessary conditions in the septic tank, a compressor should be installed for air supply.

Aerobic bacteria for wastewater treatment are responsible for the decomposition of organic suspensions. In this case, wastewater is mixed with air bubbles. To prevent the washing off of aerobic bacteria by a strong stream of water, special shields made of fleecy fabric are used.

This type of bacteria helps to ensure a sufficiently high degree of decomposition of waste in effluents, however, one should take into account the fact that, as a result of this decomposition, a solid sediment forms at the bottom of the treatment plant. Its quantity is small and can be easily removed without the use of a cesspool machine..

In the process of processing organic waste, this type of bacteria releases heat and carbon dioxide, without spreading an unpleasant odor. Waste water after aerobic treatment can be diverted safely to drainage wells or ditches. The precipitate formed after cleaning can be used as a garden fertilizer.

Unlike aerobic, anaerobic bacteria do not require oxygen for the life process. That is why in the septic tank with anaerobic bacteria, a characteristic process of fermentation or decay of organic waste occurs. When rotting, part of the waste falls to the bottom of the septic tank, where it decomposes. At the same time, bacteria cleanse wastewater.

It is worth noting that the anaerobic septic tank – bacteria determine its type – requires cleaning using a sewage machine. The fact is that the solid sediment formed as a result of decay cannot be removed on its own, in addition, it is also impossible to use it as a garden fertilizer. This is due to the fact that various pathogens are in the sediment. Another disadvantage of anaerobic wastewater treatment is that this process is accompanied by an unpleasant odor..

Anaerobic Wastewater Treatment

After the anaerobic bacteria for the septic tank are subjected to wastewater treatment, it is necessary to carry out post-treatment. It will precede the discharge of water into drainage or soil..

As a rule, post-treatment is carried out in wells or filtration fields having sand and gravel backfill. In this case, the post-treatment will be aerobic, thanks to soil bacteria.

It is worth noting that if the soil cannot be considered filtering, then all work on the device of the filtering fields will be a waste of money.

As already mentioned, a particular type of septic tank involves the use of a certain type of bacteria, however, for greater efficiency in wastewater treatment, it is recommended to combine these living microorganisms. So, if the main stage of wastewater treatment is carried out with the participation of anaerobic bacteria, then post-treatment can be carried out using aerobic bacteria. This allows you to bring the degree of water purification up to 98-99%.

Thus, bacteria for septic tanks and various biological products are one of the main and functional elements necessary for the effective operation of the septic tank..
