Organic effluents refer to the discharge of waste or pollutants that consist of all-natural and organic materials. Synonyms for organic effluents could include terms such as sewage, wastewater, sludge, biomass, or organic waste. These terms all refer to the same type of waste that is either a byproduct of human or animal activity or a natural process. Organic effluents are typically biodegradable, which means they can break down naturally and typically pose less harm to the environment than other types of waste. These synonyms can be used interchangeably in the context of waste management and disposal, and often appear in academic literature on pollution and the environment.
