Chapter 1: About septic tank

1.1 Types of septic tanks

There are several types of plastic septic tanks available. The most common types include: 

1. Polyethylene septic tanks: These are the most common type of plastic septic tanks, made from high-density polyethylene (HDPE) or low-density polyethylene (LDPE). They are lightweight and easy to install and are resistant to corrosion and abrasion. 

2. Polypropylene septic tanks: These tanks are made from polypropylene and are known for their durability and strength. They are also resistant to chemicals and high temperatures, making them ideal for industrial or commercial settings. 

3. PVC septic tanks: These tanks are made from polyvinyl chloride (PVC) and can be custom-made to any size. They are lightweight and easy to install, and can be used in residential, commercial, and industrial settings. 4. Fiberglass-reinforced plastic (FRP) septic tanks: These tanks are made from a combination of fiberglass and plastic resin. They are lightweight, durable and have a very long life span. They can be used in both residential and commercial applications. 

5. Cross-linked polyethylene (PEX) septic tanks: These tanks are made from PEX, which is a type of plastic that has high impact strength and is resistant to extreme temperatures. They are lightweight and durable, and are suitable for use in both residential and commercial applications. 

Each type of plastic septic tank has its own advantages and drawbacks, depending on factors such as cost, durability, and intended use. It's important to choose an appropriate plastic septic tank based on your specific needs and local regulations. It's always a good idea to consult with a professional to determine the best type of septic tank for your property.

1.2 SMC Septic Tank

The SMC septic tank is formed by one-time molding of sheet molding compound. Compared with the traditional hand-wound FRP(fiberglass reinforced) material, the SMC septic tank has stable quality, lighter weight and higher strength.

SMC septic tank can be equipped with sewage biochemical technology, using anaerobic filter bed, biological filtration cycle treatment process, through the activity of microorganisms in the equipment to effectively remove BOD, COD, SS, NH3 and other organic substances in sewage, and the treated water quality can be directly introduced into the lake Rivers, reaching the first-level A or B standard of "Pollutant Discharge Standard for Urban Sewage Treatment Plants (GB 18918-2002)"

Over the years, HAILI's products have spread throughout East Asia, South Asia, South America, Middle East and Africa, and are the premium choice for local distributors and customers. 

Septic tank is based on sewage biochemical technology, which basically concentrates purification including the latest sewage treatment technology. After sewage enters the purification tank, the precipitation separation tank is pretreated to remove the particles with large proportion and suspended matter, and improve the biochemical property of sewage.

1.3 PE Septic Tank

PE septic tanks, also known as polyethylene septic tanks, are a type of underground wastewater treatment system that is made from high-density polyethylene (HDPE) or low-density polyethylene (LDPE). PE septic tanks are popular due to their durability, lightweight construction, and resistance to corrosion and chemicals. PE septic tanks are commonly used in residential, commercial, and industrial settings. They are easy to install and are less expensive than other types of septic tanks, such as concrete or steel. The lightweight design of the PE septic tank also makes them easier to transport and install, which can save on labor costs. PE septic tanks range in size from small tanks designed for individual homes to larger tanks designed for industrial or commercial use. They are capable of handling large volumes of wastewater and are suitable for a variety of applications, such as domestic sewage, commercial wastewater, and industrial process water. 

One of the advantages of PE septic tanks is their resistance to corrosion and chemicals. Unlike metal septic tanks, which can rust and deteriorate over time, PE septic tanks are impervious to these materials. This reduces the risk of leaks or system failures, and can extend the useful life of the tank. Another advantage of PE septic tanks is their ease of maintenance. The tanks can be easily cleaned and serviced, and require less maintenance than other types of septic tanks. Regular pumping and cleaning of the tank can prevent blockages and backups, while proper use and disposal of household chemicals and products can reduce the risk of damage to the system. PE septic tanks are also environmentally friendly. They are designed to handle and treat wastewater, which can protect the environment and prevent contamination of nearby groundwater or surface waters. Proper installation and maintenance of the septic tank can also reduce the risk of contamination and protect public health. 

Overall, PE septic tanks are a popular choice for wastewater treatment in a range of applications. They are durable, cost-effective, and easy to install and maintain, making them a practical and efficient solution for homes, businesses, and industrial sites.

Chapter 2: Choose SMC septic tanks or PE septic tanks?

 The choice between an HDPE septic tank and an SMC septic tank would depend on a variety of factors, such as your budget, location, and specific needs. Here are some general considerations to keep in mind:

•HDPE (High-Density Polyethylene) septic tanks are generally more affordable than SMC (Sheet Molding Compound) tanks.

•SMC septic tanks are known for their durability, resistance to corrosion, and longer lifespan compared to HDPE tanks.

•HDPE septic tanks may be more suitable for areas with rocky soil or where there is a risk of ground movement, as they are more flexible and less likely to crack or break.

•SMC septic tanks may be a better choice for areas with high water tables or where there is a risk of flooding, as they are more buoyant and less likely to be damaged by water pressure.

•Consider the size and capacity of the tank, as well as any additional features or accessories (such as filters or pumps) that may be necessary for your specific situation.

Ultimately, it is best to consult with a professional in the septic tank industry to determine which option is best for your specific needs and circumstances.

Chapter 3: Plastic septic tank maintenance guides

Here are some general maintenance tips for plastic septic tanks:

1. Regular inspection: Have your plastic septic tank inspected by a professional at least once a year to check for cracks, leaks, or other damage.

2. Pumping: Regularly pump your plastic septic tank to remove solid waste and sludge buildup. The frequency of pumping depends on the size of your tank and the number of people in your household, but it is typically recommended to pump every 3-5 years.

3. Avoid flushing harmful materials: Do not flush any harmful materials down the toilet or sink, such as chemicals, paints, oils, or medications, as they can damage the septic system and contaminate the environment.

4. Protect the tank: Do not build anything on top of or near your plastic septic tank, and avoid driving heavy vehicles over it, as this can cause damage to the tank.

5. Monitor water usage: Excessive water usage can overload your septic system and cause it to fail. Be mindful of water usage, fix any leaks or running toilets promptly, and consider using water-efficient fixtures and appliances.

6. Use a bacterial treatment: Consider using a bacterial treatment to help break down the solids in your septic tank and improve overall function.

7. Maintain drain fields: Regularly maintain and monitor the drain fields connected to your septic system, as they play an important role in the overall function of the system.

It's important to note that these are general guidelines and the specific maintenance requirements for your plastic septic tank may vary based on factors such as the size of your tank, the number of people using it, and the environment it's in. It's best to consult with a professional in the septic tank industry for specific recommendations on maintaining your septic tank.
