The document discusses different types of wastewater treatment processes including preliminary, primary, secondary, and tertiary treatments. It also describes anaerobic treatment which uses bacteria to break down waste without oxygen and produces methane and carbon dioxide, but does not create a standard effluent. In contrast, aerobic treatment uses oxygen and converts waste into carbon dioxide and water through bacterial respiration, changing the oxygen content of the effluent.
