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. Typical processes include chemical treatment and pressure filtration.
A condition in which high levels of dissolved oxygen are made available.
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.
Agronomic Loading Rates
The annual whole biosolids application rate designed to:
(DBP40) Enhanced Coagulation – Basics (1280)
Alternative Compliance Criteria
Alternative Compliance Criteria (ACC)— Alternative criteria that can be used to achieve either monthly or annual compliance with the enhanced coagulation requirements of the DBP Rule.
A condition in which dissolved molecular oxygen is not present, however, some chemically bound oxygen may be present.
Also known as anaerobes. Bacteria that live and reproduce in an environment containing no "free" oxygen or DO (this type of environment is referred to as anoxic conditions). Anaerobic bacteria obtain their oxygen supply by breaking down chemical compounds which contain oxygen, such as sulfate.
