Qualification workflow
Four Steps from Operating Data to Contract Specification
A defensible bulk quotation separates system hydraulics from media laboratory properties.
- 01
Define the duty
Identify target contaminants, inlet concentration, and treatment objective.
- 02
Size the system
Confirm flow rate, EBCT, temperature, pH/humidity, and pressure-drop limits.
- 03
Match the grade
Select coconut GAC, coal GAC, wood PAC, or extruded pellets with lab samples.
- 04
Lock the COA
Confirm ASTM test methods, guaranteed limits, and packaging before FCL dispatch.
