Contaminant Removal Ix Volumetric Regeneration Trigger

Direct answer: When breakthrough of a regulated contaminant (not just hardness) is the failure mode being guarded against, a volumetric regeneration trigger set at a conservative fraction of the resin's rated gallons/CF capacity is a stronger control philosophy than a simple time-clock trigger, since it ties regeneration to actual measured throughput rather than an assumed usage rate.

Confidence: confirmed

Applies when	ion exchange, resin regeneration, uranium removal, radionuclide, MCL compliance
Avoid	time-clock regeneration, breakthrough sampling only (Controls)
Recommend instead	Clack WS2H/F (Ion Exchange Control Valve)
