Feed Equipment Calibration or Verification

Calibration is the process of measuring the chemical delivered at various equipment settings. The measured output is then used to set the feeder to its needed output. This is necessary for accurate dosing when manually adjusting pumps that have speed or both speed and stroke dials. Cahbration data can also be used to adjust digital settings such as maximum output. 

Feed equipment verification involves comparing actual outputs to the expected outputs (spot-checking). Many treatment plants require chemical feeders (for example, metering pumps) to be verified on 

Chemical Storage Issues Suggested Storage Conditions 

Chlorine gas Leak containment Containment building and gas scrubber 

Sodium hypochlorite Strength decay Control temperature (less than 85°F) and dilute to reduce rate of decay, limit storage to less than 28 days, or monitor strength
