The accumulation of one material on the surface of another material through physical bonds
Consists of additional biological or chemical treatment processes (beyond secondary treatment) that are employed to remove constituents such as nitrogen and phosphorus, that are not reduced significantly as a result of secondary treatment. Any process of water renovation that upgrades treated wastewater to meet specific reuse requirements. May include general cleanup of water or removal of specific parts or wastes insufficiently removed by conventional treatment processes.

Also called aerobes Bacteria that must have molecular (dissolved) oxygen to survive. Bacteria that will live and reproduce only in an environment containing oxygen, which is available for their respiration (breathing), namely atmospheric oxygen or oxygen dissolved in water. Oxygen combined chemically, such as in water molecules (H2O), cannot be used for respiration by aerobic bacteria.
