SMC septic tank structure
The three-chamber septic tank consists of three connected tanks. The volume ratio of each tank is 2:1:3 in principle. The two middle ones are connected by fecal pipes. Anaerobic fermentation is mainly used, and the middle layer is feces and parasite eggs. The mixed liquid with a specific gravity greater than the general specific gravity uses the principle of easy precipitation to make the feces in the pool ferment and decompose after 30 days. The feces in the middle layer flows from pool 1 to pool 3 to achieve the purpose of precipitation and killing feces. The purpose of eliminating pathogenic factors is to turn the feces in the three pools into harmless high-quality ecological farmyard manure, and the feces in the three pools into harmless high-quality ecological farmyard manure.
Compared with plastic and concrete materials, it is more durable and has better long-term use effect, especially good waterproof performance, because concrete is not waterproof, and resin is an impermeable material component. Compared with plastic, molded septic tanks are truly worth the money, because resin fiberglass will not bend and will withstand groundwater pressure much better than the base.
As shown in the figure below.

Operating Process:
The primary anaerobic chamber serves to accept fresh feces, anaerobically ferment, decompose, and separate the layers, consisting of top scum, middle liquid, and bottom sludge. It also captures and settles parasitic eggs.
The disinfection and egg-killing clarification tank primarily serves the purpose of clarification, ensuring that the discharged wastewater is environmentally safe.

The molded septic tank is made of advanced fiberglass reinforced plastic (FRP) material through a precise molding process. The specific steps are as follows:
Mold design and preparation
The production process starts with mold design. According to the shape and size requirements of the product, high-precision molds are designed and manufactured. The mold is made of high-strength steel to ensure accuracy during multiple uses.
Raw material preparation
High-quality glass fiber and resin are selected as raw materials. The glass fiber reinforced material ensures the structural strength of the product through optimized arrangement; the resin gives the septic tank excellent chemical corrosion resistance and durability.
Molding
Laying glass fiber in the mold and pouring the resin mixture, the high temperature and high pressure molding process is used to solidify the material in the mold. This process ensures the sealing and strength of the septic tank and avoids water leakage and seepage.
Demolding and finishing
The molded septic tank is carefully removed through the demolding process. Subsequently, professional technicians finely trim and polish the product to ensure that every detail meets the design requirements and the surface is smooth and flawless.
Quality Inspection
Each molded septic tank undergoes strict quality inspection before leaving the factory, including strength test, sealing test, and corrosion resistance test to ensure the long-term stability of the product in various environments.
Packaging and Delivery
Finally, the product is cleaned and packaged to ensure safety and integrity during transportation, and is shipped to the customer's designated location in a timely manner.
