Biochemical Oxygen Demand definition

Biochemical Oxygen Demand. (BOD) shall mean the quantity of oxygen utilized in the biochemical oxidation of organic matter under standard laboratory procedure in five (5) days at 20 degrees Centigrade, expressed in milligrams per liter.

Biochemical Oxygen Demand or “BOD” means the quantity of oxygen utilized in the biochemical oxidation of organic matter under standard laboratory procedures for five (5) days at twenty (20) degrees centigrade, usually expressed as a concentration (e.g., mg/l).

Biochemical Oxygen Demand. - (5 day) (BOD5) - means the quantity of oxygen utilized in the biochemical oxidation of organic matter under standard laboratory procedure contained in Standard Methods in five days at 20oC, expressed in terms of weight and concentration (milligrams per liter).

Examples of Biochemical Oxygen Demand in a sentence

• For publicly owned treatment works, the 30-day average percent removal for Carbonaceous Biochemical Oxygen Demand (CBOD5) and Total Suspended Solids shall not be less than 85 percent unless otherwise authorized by the permitting authority in accordance with 40 CFR Part 133.102, as incorporated by reference in 327 IAC 5-2-1.5. The permittee must monitor the influent and effluent CBOD5 and TSS at least once per month and calculate the percent removal to ensure compliance with the required 85 percent removal.

• For publicly owned treatment works, the 30-day average (or Monthly Average) percent removal for Biochemical Oxygen Demand and Total Suspended Solids shall not be less than 85 percent unless otherwise authorized by the permitting authority in accordance with 40 CFR 133.103.

• Water Authority review and approval of the proposed system is a condition for obtaining a Building Permit.• The proposed development requires Aerobic Treatment Unit(s) with NSF/ANSI Standard 40 (or equivalent) certification that, when operated and maintained per manufacturer’s guidelines, the system achieves effluent quality of 30 mg/L Biochemical Oxygen Demand and 30 mg/L Total Suspended Solids.

• Percent RemovalFor publicly owned treatment works, the 30-day average percent removal for Biochemical Oxygen Demand and Total Suspended Solids shall not be less than 85 percent in accordance with LAC 33:IX.5905.A.3. andB.3. Publicly owned treatment works utilizing waste stabilization ponds/oxidation ponds are not subject to the 85 percent removal rate for Total Suspended Solids.

• Commercial, Institutional and Industrial customers that discharge wastewater to the public sewer characterized by excess strength of Biochemical Oxygen Demand (BOD) and/or Total Suspended Solids (TSS) shall be assessed a Quality Charge Rate established by MSD.
