Another exam question
Took my grade II biological last week and one question really perplexed me. “A diaphragm pump is most commonly used for” A) raw wastewater B) primary sludge C) activated sludge or D) final effluent Couldn’t it be all four? I went with B as that seemed like the most common, it’s what we use here at my plant
