A Cannery waste is typically characterized by which set of parameters?

• A. BOD, TSS and pH
• B. COD, Oil & Grease
• C. Ammonia and Nitrate
• D. Color and Odor

Answer: (A)

Cannery wastewater is best understood by looking at its biodegradable organic load, the solids it carries, and its acidity/alkalinity, because these factors directly govern how the waste behaves in treatment. Biochemical Oxygen Demand shows how much oxygen microbes will need to break down the biodegradable organics, which is central to sizing aeration and the reactor itself. Total Suspended Solids tell you how much material will settle or get trapped in screens and clarifiers, affecting solids handling and filtration steps. The pH reveals how acidic or basic the wastewater is, which influences microbial activity, chemical dosing, and equipment corrosion. Taken together, these three parameters give a practical picture of cannery waste for design and operation of a treatment system.

Other measures like COD represent total oxidizable material (including nonbiodegradable parts), which is useful but less directly tied to biological treatment performance; Oil & Grease highlights fats but isn’t as universally descriptive for cannery effluent; ammonia/nitrate reflect nitrogen content, and color or odor describe aesthetics, but they don’t define the typical treatment-plant impact as clearly as BOD, TSS, and pH.
