The correct answer is option 'B' - 1, 2.
Explanation:
Turbidity and slow sand filter:
- Turbidity refers to the cloudiness or haziness of water caused by the presence of suspended particles such as clay, silt, and organic matter.
- Slow sand filters are a type of water treatment system that use a combination of biological, physical, and chemical processes to remove impurities from water.
- Slow sand filters are generally very effective in removing turbidity from water.
- The filter bed in a slow sand filter consists of a layer of fine sand, which acts as a physical barrier to remove suspended particles from water.
- As water passes through the filter bed, the suspended particles get trapped in the sand, resulting in clear water.
High initial cost of slow sand filter:
- Slow sand filters are known for their high initial cost compared to other water treatment technologies.
- This is primarily because slow sand filters require a large area to accommodate the filter bed, which can be expensive to construct.
- Additionally, slow sand filters often require regular maintenance and cleaning to ensure optimal performance, which can add to the overall cost of the system.
Skilled supervision in slow sand filter:
- Slow sand filters require skilled supervision to ensure proper operation and maintenance.
- The filter requires regular monitoring of the flow rate, turbidity levels of the influent and effluent water, and periodic cleaning of the filter bed.
- Skilled operators are needed to assess the condition of the filter bed, identify any issues or blockages, and take appropriate corrective measures.
- Without skilled supervision, the filter may not operate efficiently and may not effectively remove turbidity from water.
In conclusion, statement 1 (The slow sand filter is not efficient in removing turbidity) is incorrect, as slow sand filters are generally effective in removing turbidity. However, statement 2 (The slow sand filter has a high initial cost) is correct, as slow sand filters are known for their high initial cost. Statement 3 (Skilled supervision is required in slow sand filter) is not mentioned in the question, so we cannot determine its correctness. Therefore, the correct answer is option 'B' - 1, 2.
