Testing

The conditions and problems a papermill has is often different from one another. This may be because of a multitude of things be it differences in types of paper produced, the types of woods used, difference in raw materials used, different additives, or a different process structure. Due to this, every single papermill needs to be inspected and tested to identify the problems unique to each papermill.

PT. ENVIRA INDONESIA offers testing services to help identify the needs of a papermill allowing for accurate troubleshooting to offer the best available solutions.

The FTIR (Fourier Transform Infrared Spectroscopy) testing method is used to detect and identify any contaminants in the sample allowing for more effective selection of additives and to ensure final product quality.

The Scan pro is a device used to check the permeability of the felt in the press. This ensures that our chemicals work in reducing any buildups on the felt allowing for less downtime spent for felt maintenance.

Dissolved oxygen is always present in water and is measured as the ORP (oxidation reduction potential). The ORP is used as a baseline to help identify any anomalies in the process condition which can be used to diagnose the problems in a papermill. It is also used to ensure that we can provide each papermills with the highest performance products under their process conditions.

The EGT (Entrained Gas Tester) is a device used to check for how much gas is entrained in the water. By doing so we can ensure that there will be no foam formation in vital areas of the process.

The aerobic bacteria is a bacteria that requires oxygen to grow and cultivate. The plate count method is used to check the number of aerobic bacteria present in the sample. This test is done to numerate the dosage required for the chemicals and to ensure that the amount of these bacteria is not overwhelming that it causes anomalies in process conditions and in the finished product after the dosing.

The anaerobic bacteria, such as sulfur reducing bacteria, are often present in areas with no circulation of water, i.e., dead areas. The test kit is used to determine the number of anaerobic bacteria present in the sample. This test is done to numerate the dosage required for the chemicals and to ensure that the amount of these bacteria is not overwhelming that it causes anomalies in process conditions and in the finished product after the dosing.
