Polyethylene septic tank or polyseptic tankPolyethylene Septic Tank Made of polyethylene hence compared to Concrete septic tank and Steel tank is lighter and more resistant to rust. The light weight makes it easier to work and install plastic septic tanks. Plastic septic tanks have a specific gravity of about 0.97, which is lower than the specific gravity of water. The low weight makes the tank float when it reaches the ground water table level. Therefore, before installing a plastic septic tank, you should check the level of the underground water table in that particular area and provide anchorage for the tank so that the floating or shifting of the tank is eliminated.

  • The light weight and ease of carrying and installing the polyethylene septic tank make this product unique.
  • It is possible to move even a few years after the initial installation, without damaging the structure.
  • The ease of working and draining sludge from it due to sludge drainage are other positive features of this product.
  • High resistance to It has ultraviolet radiation.
  • Smell leakage from the polyethylene septic tank is practically zero.

Dimensions of polyethylene sewage septic tank

The dimensions of the polyethylene septic tank are variable and can be produced in different volumes. This possibility is significant because this septic tank according to the formula cannot be less than 4.4 cubic meters. For example, a septic tank of 3.5 cubic meters with a diameter of 1.2 meters and a length of 3.1 meters can be produced.

use of polyethylene septic tank

Polyethylene septic is widely used in various sectors household sewage treatment, health and a href=”https://www.atiaco.com/%d9%be%da%a9%db%8c%d8%ac-%d8%aa%d8%b5%d9%81%db%8c%d9% 87-%d9%81%d8%a7%d8%b6%d9%84%d8%a7%d8%a8-%d8%b5%d9%86%d8%b9%d8%aa%db%8c/> They have an industrial wastewater treatment package. In the polyethylene septic tank, the steps of pre-treatment and treatment of sanitary wastewater produced from residential units, commercial and office complexes, hotels and restaurants take place. Disposal of contaminated particles, fats and oils found in wastewater from restaurants and dining halls in polyethylene septic tanks and grease trap to help prevent the rapid filling of wells and clogging of pipes due to the accumulation of fat and coarse sediment particles is used.

Polyethylene septic storage

No specific time frame can be suggested for emptying the polyethylene septic tank, because it depends on the working conditions of the tank and the amount of raw sewage. In general, if the septic tank capacity is accurately calculated and the waste is dumped into If the sewage system does not occur, this interval may last more than a year. No disinfectant should be disposed of during the treatment and operation of the tank. Because it kills bacteria.
Emptying and cleaning septic tank polyethylene can be done by pump. Of course, it is possible to remove existing sewage and sludge by hand and even There is drainage from the tank. When draining, you should not pull out all the sludge material, as this is unnecessary, and in addition, a small amount of bacteria-containing sludge is required in the tank. Of course, fine materials and unseparated materials must be emptied and destroyed.

types of polyethylene septic tank system

Septic tank

The polyethylene septic tank is made for domestic and raw sanitary sewage treatment. Heavy solids can settle at the bottom of the tank, and greases and oils, fats and light solids settle on top of the tank.

conventional system

A conventional septic system is a decentralized wastewater treatment system that has a tank and also It is made of an underground sewage infiltration system and is suitable for homes or finally for small businesses and does not respond to high sewage production. Using this design, the wastewater is diverted from the conventional system to a shallow underground tank and passes through a special filter located on top of the tank to remove sand, dirt and other pollutants.

room system

Polyethylene septic tank room has been used for a long time in different countries. It is a suitable alternative to sand systems, it is made in various forms, including tubular chambers. The main advantage of the room system is the high ease of construction and delivery. This type of system is very suitable for areas where there is a lot of sewage production.

Drip distribution system

The drip distribution septic tank system is a type of septic tank system based on the dispersion of wastewater. Works. The drip distribution system can be used in many fields of wastewater treatment. > be used. One of the most important advantages of the drop distribution system is the creation of drop edges in the size of 6 to 12 inches. But this system is definitely not without its weaknesses. The disadvantage of drip distribution septic tank is the large tank required for this system, which if not installed, the operation time will increase. This system is based on electricity and it should not be forgotten that the costs of electricity consumption are also added to the costs of the system.

Aerobic treatment unit

Units municipal sewage treatment package they use to treat sewage. These systems have a smaller scale compared to urban wastewater treatment packages. An aerobic polyethylene septic system injects oxygen into the septic tank. Oxygen can increase the natural bacterial activity inside the system, and under these conditions, organic substances and pathogens are purified. In some cases, the polyethylene septic tank for aerobic treatment can consist of two tanks. The first tank can include a pre-treatment tank and the second tank is for final treatment, disinfection and elimination of pathogens.

hill systems

The hill polyethylene septic tank is suitable for when the used areas have shallow soil or even there are many fresh water beds in those areas. This system has a sand filter that after passing through it, the wastewater partially loses its solids and oil and fats, and this is a factor in the wastewater treatment.

Septic system with rotating sand filter

Rotary sand filter systems can be built underground. It is pumped to the sand filter. This sand filter often has a PVC or concrete cover that is filled with some type of sand. After passing through this sand filter, the effluent leaves the pipes. The treated wastewater is then discharged to the drainage area.

Septic evaporation and transpiration system

Evaporative systems have unique discharge fields. After the wastewater enters the drainage section, the wastewater is evaporated using air, and unlike other system designs, the wastewater can never enter the soil. Evaporation and transpiration systems are useful only in certain environmental conditions. The climate in the areas where this system is used must be dry and have enough heat and sunlight. These systems can also work well in shallow soil.

Made from a wetland system

The wetland system mimics the treatment processes found in natural wetlands. Sewage enters this septic lagoon. Effluent in this system is free from microorganisms, plants and other media that include pathogens and organic substances.

cluster or community system

In this sewage system, a polyethylene septic tank is used for several houses, companies, etc. This system is more common in villages.

Life of polyethylene septic tank

Every product has a certain lifespan and tanks and tankers also all wear out after some time. Polyethylene tanks have a much longer lifespan than other tanks, but one of the weaknesses of these tanks is their vulnerability to severe mechanical shocks that are inflicted on one point due to the drier nature of the body compared to metal tanks. Lower.
If a polyethylene tank is placed in the open environment for a long period of time, more than 10 years, and does not have a protective layer against UV, or the concentration of anti-UV in its outer layer is low,
