Benefits of Fiberglass Septic Tank

Strong and lightweight

Fiberglass is rigid (unlike flexible plastic) but much lighter than concrete. At 250 to 350 pounds for a 1,000-gallon tank, it's easy to install without heavy equipment while still offering structural integrity that resists soil pressure and deformation.

Lower flotation risk than plastic

While still lighter than concrete, fiberglass tanks are designed with specific anti-flotation features and are less likely to shift in saturated soil than plastic tanks.

Excellent Corrosion Resistance

Fiberglass will not rust, corrode, or degrade from chemical exposure. It's impervious to hydrogen sulfide and acidic soil.

Long lifespan

Fiberglass tanks can last 30 to 40 years with proper maintenance, comparable to plastic and approaching concrete's longevity.

Fiberglass Septic Tank Structure Design

Sediment Precipitation Area
Fiberglass septic tanks have the most significant material that sinks into the bottom sediment treatment sewage on the domestic sedimentation. It settles down at the bottom while it is overlayered with the upper water surface. A highly active microbial population is developing to degrade the complex structure of refractory organic matter to decompose it quickly.

Partition
Upon fiberglass septic tank installation, the owner must observe that the DC water is produced into circulating water to increase the retention time of sewage in the pool. In this manner, the sewage in the collection and sedimentation sludge will contact longer than produce more microorganisms making the sewage decomposition swallow.

Filter Processing Area
We, fiberglass septic tank manufacturers, have developed a unique style and function as it adopts advanced biofilm treatment technology used at home or abroad. Many microorganisms breed on the surface of the filter after a certain period of cultivation to form a biofilm contact. The organic matter in the sewage is stopped, adsorbed, and decomposed by microorganisms. This is where the effective evolutionary process happens.

The function of Fiberglass Septic Tank
