Water quality test
Water Quality Test
- A sample of raw water is taken from the screening chamber to analyze pH, turbidity ajar test, etc.
- The results are recorded in the water quality analysis form. Another sample is taken from the sedimentation tank for pH value change due to the use of aluminum Sulphate (coagulant) which is acidic in nature.
- Another sample is taken from the storage tanks to analyze for turbidity, pH, and residual chlorine levels.
- Other samples for physio-chemical and bacteriological analysis are taken at random within the distribution system. The results are recorded in physio-chemical and bacteriological forms.
- At a minimum, the sampling is done on a daily and weekly basis. The company subjects water analysis tests to an accredited independent laboratory for validation every quarter.
- The laboratory technologists determine the extent and frequency of in-process inspection/testing based on the control methods applied, the weather conditions (whether dry or rainy), and previous test results.
Final inspection and test
- For the acceptance of treated water, final inspection /testing is utilized. This includes verification of satisfactory receiving and in-process inspection /tests, as well as completion of the remaining inspections/tests to ensure that the treated water conforms to specified requirements.
- Products are not released, and processes are not approved until all inspection/test activities have been satisfactorily completed and the appropriate documentation is available and authorized. All final inspections are logged in the final inspection log. On critical parts and components, as determined by the Quality Manager, a final inspection /Test &Audit report is completed.
Post delivery testing
- A layout inspection and functional test are performed to applicable customer engineering specifications and performance standards for each product as specified in the control plans.
- Unless otherwise specified by the customer, the Quality Manager determines the number of items to be evaluated. Inspection personnel record all results on the layout inspection and functional testing report form; identify the inspected items with numbers corresponding to the number of samples for audit and approval.
- The Quality Manager performs an audit of the samples and records all findings on the layout inspection and functional testing report. All results are available for customer review.
Inspection and test records
- Inspection/test records, which show clearly whether the product/process has passed or failed the defined acceptance criteria, are established and maintained.
