What type of taps must all filters have to monitor effluent turbidity?

Filters must have effluent taps to monitor effluent turbidity because these taps are specifically designed to provide a measurement of the water quality after it has passed through the filter media. Monitoring turbidity at this point is crucial, as it indicates the effectiveness of the filtration process in removing suspended solids and particulates from the water.

Effluent turbidity readings enable operators to assess the performance of the filters and determine when maintenance or backwashing is required. This ensures that the water being distributed meets the necessary water quality standards.

In contrast, influent taps would measure the quality of water entering the filtration system, which does not provide insights into how well the filter is functioning. Bypass taps are meant to allow water to flow around the filter, and measurement taps could refer to various locations throughout the system but are not necessarily specific to filter effluent monitoring. Thus, effluent taps are essential for ensuring proper water quality control post-filtration.
