So, why this design is reliable ?

  1. Septic tank does not contain mechanical parts and components.

  3. Additional strength is provided by stiffeners and molecular welding, which combines substances with maximum reliability.

What is the construction of this septic tank? This is a polypropylene tank with compartments, in which the whole sewage treatment process takes place. There are only four compartments and they are connected by a system of airlifts - plastic tubes, through which the drains are distilled with the help of compressors. Each of the departments performs a separate function.

  1. The first compartment is the receiver, it is there that the sewage treatment process begins. It is a sedimentation tank, where the contents "stand" for some time. In this case, the water brightens, the solid particles are eliminated and go to the sediment.
  2. The second compartment is called the aero tank. This is where the key cleaning takes place. Aerobic bacteria that fall outside (most often do not need to buy them additionally) are engaged in this, having fallen into the ideal conditions of the second compartment, they actively proliferate and process wastewater. At the same time, the chamber is additionally supplied with oxygen for greater bacterial activity. Nitrates in this compartment are destroyed by the method of intermittent aeration.
  3. The third compartment is a secondary settling tank. Here the silt is divided into fresher and older particles. Since fresh sludge is easier - it is sent back to the previous compartment with a septic tank for recycling, heavy sludge goes to the receiver for final storage and subsequent removal manually (a couple of times a year).
  4. The fourth, last compartment removes most of the suspended particles and can discharge water to the outside. You can connect a pump with which you can use water to irrigate the area.

The efficiency of wastewater treatment with this septic tank is 95% or more. Purified water has no extraneous odors, the area around the septic tank also does not spread unpleasant odors. The septic tank can work both the whole year, and in certain seasons. The service life of a septic tank reaches 50 years.
