Describe onsite disposal systems.
Answers
Answer:
Onsite (or decentralized) wastewater treatment systems are used to treat wastewater from a home or business and return treated wastewater back into the receiving environment. They are typically referred to as septic systems, because most involve a septic tank for partial treatment.

Explanation:Treatment systems
The most common types of onsite wastewater treatment systems are:
septic tanks
aerated wastewater treatment systems (AWTS)
biological filter systems
composting toilets (dry and wet)
Wastewater can be treated to three standards:
Primary - minimal treatment involving flotation and settlement to separate solids and liquids, and disposal of the clarified but still contaminated effluent (such as septic tanks and composting toilets).
Secondary - more advanced treatment using air and biological processes to decompose the solids and chlorine to disinfect the liquid to a standard safe for irrigation (such as aerated wastewater treatment systems).
Tertiary - highly advanced systems that use air and biological processes as well as membranes and UV disinfection to treat wastewater to a very high standard (such as membrane filtration and advanced aerated wastewater treatment systems).
