Septic Tanks & Sewage Plants - What's The Difference?

What Is A Septic Tank?
multiple chambers. Wastewater enters one end of the septic tank, before being separated into solids (sludge) and oils (scum). The separated wastewater (effluent) then leaves the septic tank via an outlet and goes into a drainage field.
through the ground to remove bacteria, before being dispersed and rejoining watercourses.

How Does A Sewage Treatment Plant Work?
way. Rather than just separating the sludge and scum from the wastewater, a sewage treatment plant uses a pump to aerate the chamber. This process encourages the growth of 'good' bacteria that will help to break down the harmful bacteria that's in the wastewater. Once this process has been completed, the liquid water can be released from the plant directly into watercourses, such as streams.
Key Differences
Aside from the cleanliness of the effluent, there are also a number of other differences.
* Sewage treatment plants require electricity to run the air pump, however septic tanks can run power-free
* Septic tanks don't require servicing (although they do require emptying), whereas sewage treatment plants require servicing and emptying
* Septic tanks generally require emptying more frequently than sewage treatment plants

Process description
1. After passing through the septic tank, the sewage from each household is collected by the sewage pipe network. The animal and vegetable oil in the sewage must be removed by a grease trap before entering the sewage pipe network for treatment.
2. After the domestic sewage is collected in the pipeline network, the debris and large particles are separated through the bar screen well to prevent blockage.
3. After separated by the bar screen well the sewage enters into the equalization tank. The purpose to set up equalization tank is to control water quality and water quantity to meet process requirements, so that the water quality and water quantity entering the treatment tank are more stable.
4. The sewage in the equalization tank is pumped to the treatment tank for treatment through a lifting pump.
5. The intelligent sewage treatment tank is designed with five compartments, they are: oil separation and sand sedimentation compartment, anaerobic compartment, anoxic compartment, aerobic compartment and sedimentation compartment. It degrades COD in sewage through the action of microorganisms and realizes denitrification at the same time.
6. After being treated by the intelligent sewage treatment tank, the sewage enters the ecological filter for polished treatment. The sewage is deeply treated by the synergistic effects of artificial media, plants, and microorganisms, ensuring that the sewage is stably discharged in compliance with the standards. The effluent from the ecological filter flows into the nearby water body.
7. The intelligent sewage treatment tank is made of SMC/Glass fiber reinforced plastic material, we provide 1 year warranty for the whole system.
