Manufacturing Process
Each CalSul Sphere Cartridge is manufactured in a cleanroom environment using precision bead-filling technology. The calcium sulfite balls are tested for purity, hardness, and surface area. Cartridges are sealed via ultrasonic welding, and undergo pressure testing, flow-rate calibration, and chlorine-removal validation before packaging.
