11) Which of the following does not help to minimize BOD in our wastewater?

A. Avoiding BOD contributors from getting into the sink and floor drains
B. Scraping off sauce residues and leftovers using a spatula before soaking or washing pots and utensils
C. Putting leftover food like rice into the drip pan

To minimize BOD in wastewater, preventing organic matter from entering water sources is crucial. Avoiding BOD contributors, scraping off food residues, and not putting leftover food into drip pans are effective ways to reduce BOD levels.

Explanation:

Biological Oxygen Demand (BOD) refers to the amount of dissolved oxygen needed by microorganisms to decompose organic matter in water. To minimize BOD in wastewater, it is crucial to prevent organic matter from entering the water sources. Therefore, options such as avoiding BOD contributors from entering drains and scraping off food residues before washing utensils help in reducing BOD levels.

Putting leftover food like rice into the drip pan does not help minimize BOD in wastewater as it would still contribute to organic matter reaching the water bodies, increasing BOD levels.
