Good sealing: no breakage and slag layer caused by foundation settlement, solving the problem of groundwater pollution by brick septic tank.

High compressive strength: the structure of the product is reasonably designed and uniformly pressurized, and it has been tested for more than 200 times, and the trucks do not settle and deform when crushed on the upper part of the tank.

Small footprint: the product occupies about 45% of the area of traditional septic tank, saving land resources.

Convenient installation and construction: it can be freely combined and installed according to the needs of the site, and can be put into use in 2 hours after installation.

Good treatment effect: the upper and lower layers of this product's bulkhead are designed in a staggered way, the original direct-flow flooding is changed to circulating flooding, the substrate passes smoothly, and the application of anaerobic biofilter (AF) packing system intercepts more biomass, and the wastewater treatment capacity has been increased by more than double than that of a traditional septic tank of the same volume.

Long service life: resistant to moisture, acid and alkali, oxidation, high and low temperature without deformation, normal use of more than 50 years.

Low economic index: the overall cost is 80% of reinforced concrete structure, and it is the environmental protection product promoted by urban construction department.
