In Drum Filters, flow rate is a crucial metric that measures the volume of water passing through the filter per unit time. It's essential for determining the filter's efficiency and capacity. At Fiverkoi, we employ a rigorous method to accurately assess and mark the flow rate of our drum filters.

Key Factors Influencing Flow Rate

Several factors can influence the flow rate of a drum filter:

• Filter Mesh: The size of the filter mesh directly affects the flow rate. Finer meshes allow for smaller particles to be filtered, but they also restrict flow.

• Filter Area: A larger filter area can handle a greater volume of water, leading to a higher flow rate.

• Water Quality: The presence of contaminants, such as dirt, debris, or algae, can reduce the flow rate as they accumulate on the filter surface.

• Pump Capacity: The pump supplying water to the filter must be capable of delivering the desired flow rate.

Fiverkoi's Approach to Flow Rate Determination

At Fiverkoi, we adhere to a three-step process to determine the flow rate of our drum filters:

1. Actual Flow Rate Measurement: We avoid relying solely on the pump's rated flow rate. Instead, we measure the actual flow rate using calibrated instruments. This ensures that we have an accurate assessment of the filter's performance under real-world conditions.

2. Standard Filter Mesh Testing: We use a 150-mesh filter as a benchmark for testing. This allows us to compare the performance of different filters and determine the impact of varying mesh sizes on flow rate.

3. Conservative Rating: We apply a conservative approach to rating the flow rate. Even if our measurements indicate a higher capacity, we typically rate the filter at a slightly lower flow rate to account for potential factors that may reduce performance over time, such as filter fouling or changes in water quality.

Why a Conservative Approach?

By adopting a conservative approach, we aim to provide our customers with realistic expectations regarding the filter's performance. This helps to prevent situations where customers may be disappointed if the filter's actual flow rate falls short of their expectations. Additionally, a conservative rating can contribute to the longevity of the filter by reducing the strain on the equipment and minimizing the frequency of backwashing.

In conclusion, Fiverkoi's approach to determining flow rate in drum filters is based on a combination of accurate measurement, standardized testing, and a conservative rating. This methodology ensures that our customers can rely on our filters to deliver consistent and reliable performance.
