What condition would trigger water softener, ro and treated water check instead of the calendar?

Treated water conductivity or hardness above the limit, RO differential pressure or normalised permeate flow out of range, brine tank level low

What evidence does water softener, ro and treated water check produce for an ISO 55001 or ISO 45001 audit?

Treated water quality trend and the regeneration, clean or membrane change keyed to it

Water softener, RO and treated water check

Q: Can water softener, ro and treated water check move from a fixed interval to a condition-based check?

Convertible: a monitored condition can replace the fixed interval. A softener regenerates on volume and the outlet hardness says whether that was enough. Measure the outlet, not the calendar.

What does a water softener, RO and treated water check involve?

Water softener, RO and treated water check checks: conductivity, hardness, RO differential pressure and normalised permeate flow, brine level. Observed by online conductivity or hardness monitor; RO skid instrumentation; brine level switch. The interval: a monitored condition can replace the fixed interval.

Condition that replaces the interval: Treated water conductivity or hardness above the limit, RO differential pressure or normalised permeate flow out of range, brine tank level low
Reading that proves it: Conductivity, hardness, RO differential pressure and normalised permeate flow, brine level
Evidence an auditor accepts: Treated water quality trend and the regeneration, clean or membrane change keyed to it
First move: Fit an online hardness or conductivity monitor at the outlet with an alarm at the limit.

ISO 55001:2014 8.2 Management of change

Before any planned change is made, whether temporary or permanent, that could affect whether the asset management objectives are met, its risks are assessed, and the organization makes sure those risks are handled as 6.1 and 6.2.2 require. It controls changes it has planned and reviews the consequences of changes that ...
