500 gallon PE plastic septic tank is produced by rotational molding of high-strength polyethylene PE raw materials. 500 gallon PE plastic septic tank is formed at one time, with no seams, good overall sealing, non-toxic and tasteless; 500 gallon PE plastic septic tank has no Pollution, acid and alkali resistance, corrosion resistance, durable and economical. Normal use of 500 gallon PE plastic septic tank can reach more than 50 years.

Plastic septic tank process principle

Plastic septic tank is a treatment facility that uses the principle of sedimentation and anaerobic fermentation to remove suspended organic matter in domestic sewage.

Belongs to primary transitional living treatment structures. Domestic sewage contains a lot of feces, paper scraps, pathogens... The suspended solid concentration is 100~350mg/L, the organic matter concentration CODCr is between 100~400mg/L, and the suspended organic matter concentration BOD5 is 50~200mg/L L. After the sewage enters the septic tank and settles for 12-24 hours, 50%-60% of suspended solids can be removed. The precipitated sludge is decomposed by anaerobic fermentation for more than 3 months, so that the organic matter in the sludge is decomposed into stable inorganic matter, and the perishable raw sludge is transformed into stable cooked sludge, which changes the structure of the sludge. Reduced the moisture content of the sludge. Regularly remove the sludge and transport it to landfill or use it as fertilizer. 500 gallon plastic septic tank is the most common specification, and the price is very cheap.


Next, we will explain the workflow of 500 gallon plastic septic tank.


1. The sewage is first discharged from the water inlet to the first compartment of the septic tank, and solids with a large specific gravity and parasite eggs and other substances settle down in the first compartment, and the anaerobic bacteria in the pool water are used to start preliminary fermentation and decomposition. A grid of treated sewage can be divided into three layers: pasty manure, relatively clear manure, and solid manure. We set the capacity of the first cell of the 500 gallon plastic septic tank to 60% of the total capacity, which is about 300 gallons.

2. The preliminarily decomposed manure flows into the second compartment of the plastic septic tank, while the dung skin floating above and the dung residue deposited below stay in the first compartment to continue fermentation. In the second cell, the feces continue to ferment and decompose, the eggs continue to sink, the pathogens gradually die, the feces are further harmless, and the thickness of the dung skin and dregs produced is significantly reduced compared with the first cell. We set the capacity of the second compartment of the 500 gallon plastic septic tank to 20% of the total capacity, which is about 100 gallons.

3. The feces flowing into the third compartment are generally decomposed, and the germs and parasite eggs have been basically killed. The function of the third compartment mainly plays the role of temporarily storing the basically harmless excrement of precipitation. 500 gallon plastic septic tank is basically enough for 3 months for families and restaurants.

4. The re-sedimented manure flows into the municipal pipe network through the drain pipe.

The role of septic tanks

A septic tank is a device for treating, filtering, and depositing feces. The principle is that the solidified matter differentiates at the bottom of the pool, and the upper hydrate flows into the pipeline to prevent the pipeline from being blocked, so that the solidified body has enough time to hydrolyze. A septic tank is a small treatment structure that separates domestic sewage and anaerobically digests sludge. Its primary function is to ensure the sanitation of the living community and prevent the spread of domestic sewage and pollutants in the living environment. Temporary sludge, organic sludge is used for anaerobic erosion, and cooked organic sludge can be used as agricultural fertilizer. Pretreatment of domestic sewage, deposition of impurities, hydrolysis of macromolecular organics into small molecular organics such as acids and alcohols, to improve subsequent sewage treatment.

It is precisely because of the great role of septic tanks that septic tanks have become popular rapidly. Indispensable in our life.

500 gallons is the most commonly used volume for septic tanks. "500-gallon plastic septic tanks are mainly used for domestic sewage treatment in residential quarters, office buildings, hotels, schools, hospitals, military camps, public toilets, buildings where residents live intensively, and drainage treatment in food processing enterprises. It can also be used appropriately It is refitted and used as an oil-water filter pool in restaurants, restaurants and other places.

500 gallon plastic septic tank product description

500 gallon plastic septic tank is made of PE/PPB macromolecule plastic through one-time injection molding of domestic advanced fully computerized injection molding machine. It is a substitute for traditional septic tanks. It has good sealing performance and high strength. It is an environmentally friendly product promoted by the country.  

500 gallon plastic septic tank Features 

  • The 500 gallon plastic septic tank is one-time injection molding, which is not easy to leak and solves the leakage problem of brick septic tanks.  

  • The 500 gallon plastic septic tank has a compact structure and a small footprint. The actual footprint is about 50% of the traditional septic tank, saving land resources.  

  • PE/PPB polymer plastic material is resistant to various organic solvents and various acid and alkali corrosion. The plastic septic tank solves the secondary pollution problem of the current glass fiber reinforced plastic septic tank.

  • The product is easy to transport and easy to install and construct. It can be installed and assembled on site. After 500 gallon plastic septic tank is installed, it can be put into use.  

  • The materials used for FRP septic tanks contain alkali and have poor acid resistance, which cannot meet the 50-year requirements of architectural design standards, while the expected service life of PE/PPB polymer plastic septic tanks can be as long as 50 years or more.  

  • The 500 gallon plastic septic tank product is high-pressure injection molding, with high density, reasonable structural design, uniform pressure, high bearing strength, no subsidence, and no deformation. The rotomolded septic tank products are processed without pressure, and the product density is low, and the same wall thickness is 30% lower than the strength of injection-molded septic tanks 

  • The outer wall of the 500 gallon plastic septic tank is designed with a mesh-like rib structure, which increases the overall compressive strength and ring stiffness of the product.  

  • The top and bottom of the 500 gallon plastic septic tank are connected by hot-melt, the material is the same and the welding seal is good, while the top and bottom of the glass fiber reinforced plastic septic tank are fixed by screws and nuts, which are easy to rust and rot, and cannot be used for a long time.  

Plastic septic tanks are mainly suitable for domestic sewage treatment in rural domestic sewage treatment projects, residential communities, office buildings, hotels, restaurants, schools, hospitals, barracks, public toilets, buildings inhabited by people, and drainage treatment in food processing enterprises.  


If someone needs to install a plastic septic tank, it is recommended that you find a regular manufacturer. Although it is not expensive, you can buy a low-quality product with high-quality money.
