What is the difference between a septic system and a sewage treatment system?
assistant
A septic tank is a small underground chamber that contains a mixture of water, waste, and bacteria. The waste is broken down by these bacteria into a liquid form called effluent. This effluent then flows into a drain field where it is filtered through layers of soil and sand before being dispersed into the surrounding environment. A sewage treatment system is a larger system that uses mechanical processes to remove harmful contaminants from wastewater. These systems can include a variety of methods such as chemical precipitation, biological degradation, and physical separation.
