biological oxygen demand
requirement for oxygen by microbes in a niche used to measure drinking water equality
phases in purification and sewage treatment
primary, secondary and tertiary
primary phase
physical seperation of solid materials via settling (digester tank)
secondary phase
liquid portion of waste is subjected to microbial decomposition that is largely aerobic
tertiary phase
chemical physical or biological methods to remove additional inorganic substances liek ammonia nitrate and phosphate and to eliminate pathogens
