Explanation: Efficiency of low rate trickling filter = 100/(1+0.0044 (μ)1/2) = 100/(1+0.0044 (900)1/2) = 100/1.132 = 88.3.

Calculation of Efficiency of Low Rate Trickling Filter
Organic loading refers to the amount of organic matter that is applied to a treatment system per unit area per unit time. In the case of a low rate trickling filter, the organic loading is given as 900 kg/hectare-meter/day. The efficiency of the filter can be calculated using the following formula:
Efficiency (%) = (Organic matter removed / Organic matter applied) * 100
To calculate the efficiency, we need to determine the organic matter removed and the organic matter applied.
Organic Matter Applied:
The organic matter applied is the organic loading, which is given as 900 kg/hectare-meter/day. To convert this to kg/m²/day, we need to convert hectares to square meters.
1 hectare = 10,000 m²
1 hectare-meter = 10,000 m² * 1 meter = 10,000 m³
Therefore, the organic matter applied can be calculated as:
Organic matter applied = 900 kg/hectare-meter/day * 10,000 m² / 10,000 m³
= 900 kg/m²/day
Organic Matter Removed:
The organic matter removed is not given directly in the question. However, we can assume that the efficiency of the filter refers to the removal of organic matter. In this case, we can consider the organic matter removed as equal to the organic matter applied.
Organic matter removed = 900 kg/m²/day
Calculation of Efficiency:
Efficiency (%) = (Organic matter removed / Organic matter applied) * 100
= (900 kg/m²/day / 900 kg/m²/day) * 100
= 100%
Therefore, the efficiency of the low rate trickling filter is 100%.
Answer:
The correct answer is option B) 100%.

= 100%
Therefore, the efficiency of the low rate trickling filter is 100%.
Answer:
The correct answer is option B) 100%.
