Automatic Detergent Dosing: Checks Before Daily Operation
Automatic detergent dosing can make some laundry operations more repeatable, but the result still depends on correct setup and daily checks. The main mistake is assuming that automation removes the need for supervision. Products, tubing, programmes and safety procedures must work together as one controlled process.
Start with chemical instructions
Every cleaning product has specific usage, concentration, compatibility and safety requirements. Competent personnel should define dosing in relation to the chemical, load, soil level and water conditions. Do not copy a setting from another laundry without checking those variables.
Check line identification
Dosing lines should be clearly identified to reduce the risk of mixing incompatible products. Verify that labels and procedures are current. Leaks, damaged tubes or unmarked containers must be handled under the workplace safety process and relevant chemical documentation.
Match the programme to the load
The same quantity may not suit towels, sheets and heavily soiled uniforms. Maintain an operating table explaining which load and programme corresponds to each dosing setting. Review the configuration with the dosing-system supplier when chemicals or textiles change.
- Product name and handling instructions.
- Identification of tubes and containers.
- Programmes and loads covered by each setting.
- Maintenance and inspection record.
- Response to alarms or dosing faults.
Train the operators
Even an automated system needs operators able to recognise problems. Provide short instructions for reporting errors and stopping the process when necessary. Chemical handling and technical interventions should be restricted to authorised people.
Evaluate actual results
Compare rinsing quality, repeated loads and chemical consumption under similar operating conditions. Good dosing is not just about the volume delivered: it is about procedures that remain understandable and repeatable for the textiles actually processed.
To investigate residue and changes in rinsing, consider the water-hardness checks.
