The septic tank is necessary for the rejection of waste of a house. Precautions must thus be taken for its maintenance while taking into account its characteristics. A normal maintenance must be carried out to avoid any risk of clogging of the pipes or damage being able to block the use of dwelling of a construction.
The operation of a septic tank
The operation of a septic tank depends entirely on its design what implies that all the elements of the pit must in this periodically checked direction being. This system of treatment of waste is composed of 2 compartments with deflectors, for the entry of water and a second for their exit. These deflectors are there to prevent the passage of dirty water in the part of purification.
The use of the two compartments which can be out of concrete or plastic makes it possible to treat in a first stage waste. They undergo a biological reaction caused by the presence of bacteria. Those “consume” waste during a process: the basic anaerobe.
Bubbles are formed on the surface then forming mud particles which compose the “hat”, a crust located above solid elements which settled at the bottom of the pit.
In one second stage, waste passes in the second compartment in the form of emanations to be pretreated and stabilized. It is a substance elutriated in the form of a clear liquid which is then transferred in trenches of drainage equipped with filters to be purified.
The maintenance of its pit for its longevity and its good performance
The pits of cleansing must be the object of certain concerns to guarantee of it the use for a certain period. Draining is part of these concerns that any owner having this equipment must have. Moreover, certain controls must be carried out permanently.
Draining consists in removing pit the mud located in its bottom, but also emptying the vat grease remover. It is an obligatory stage to carry out every four years for the normal pits and every two years for the pits with all water.
The favourable period to carry out such an operation occurs during the summer period or at the beginning from the autumn. In fact, the freezing or the thaw of the ground can attack the realization of draining.
This operation is to be carried out when the level of solid elements of waste reaches two thirds of the contents of the pit. All the mud located at the bottom should not however not be removed in the first compartment. It is necessary to keep at least 20% of the substance to keep the bacteria implied in the anaerobe. For the second compartment, all can on the other hand be withdrawn. And for draining, it is necessary to fill with water the pits.
Moreover, except for draining, of controls must be carried out where it is necessary to make sure of the good progress of the biological treatment inter alia the presence of the bacteria. The owner must also make sure of the good performance of the mud tank for his role in the anaerobe, but also of the walk of the system of dispersion. |
