What this tool does
Relates flow to actual filter area and compares only against user-entered media or manufacturer limits.
When to use it
Use after identifying the exact vessel and media; include filter pressure loss in the connected pump duty review.
Inputs and supported units
Each labelled field explains the quantity it expects. Unit-system changes convert existing numeric entries once and keep calculations on a single SI internal basis. Supported shared units include L/min and GPM, metres and feet, kPa and psi, millimetres and inches, kW and hp, and °C and °F as relevant.
Calculation or decision method
How to interpret the result
Read the primary result with the supporting breakdown and warning. A plausible number is not evidence that every input, operating case or design constraint has been included.
Worked example
Two 1 m diameter vessels provide 1.571 m² total area. At 100 L/min, service loading is about 63.66 L/min/m² and flow per vessel is 50 L/min.
Assumptions
The entered water test, flow, product concentration and manufacturer values represent the same source, use and operating condition.
Limitations
The result is a transparent preliminary calculation or decision screen. It does not establish contaminant removal, potable safety, product certification, regulatory compliance or an approved treatment design.
