What is a septic tank ? Where it is used ?
Answers
Answer:
A septic tank is an underwater sedimentation tank used for wastewater treatment through the process of biological decomposition and drainage. Septic tanks allow a safe disposal of wastewater and hence are widely popular in areas that have a poor drainage system or are off the mains sewage network.
Explanation:
A septic tank is an underground chamber made of concrete, fiberglass, or plastic through which domestic wastewater (sewage) flows for basic treatment.[2] Settling and anaerobic processes reduce solids and organics, but the treatment efficiency is only moderate (referred to as "primary treatment").[2] Septic tank systems are a type of simple onsite sewage facility (OSSF). They can be used in areas that are not connected to a sewerage system, such as rural areas. The treated liquid effluent is commonly disposed in a septic drain field, which provides further treatment. Nonetheless, groundwater pollution may occur and can be a problem.✔✔⬆️⭕
