Sand Filter Media Replacement

Project Overview

This project involved the replacement of sand filter media in the wastewater treatment plant (WWTP) serving the plating TC2W process at PT Suzuki Indomobil Motor Plant Tambun I. The work aimed to restore filtration performance that had decreased due to prolonged operation. All activities were completed within a short execution period without disrupting plant operations. Process reliability and treatment continuity were key priorities.

Project Objective
The objective of this project was to restore the effectiveness of the primary filtration unit by replacing worn sand filter media, ensuring stable wastewater treatment performance, and supporting environmental compliance.

Project Scope

1. Assessment of Existing Sand Filter Media

   • Evaluation of media condition and filtration performance

   • Identification of replacement requirements

   • Confirmation of suitable media specifications

2. Sand Filter Media Replacement

   • Removal and disposal of existing sand media

   • Internal cleaning of the filter vessel

   • Installation of new sand filter media

3. Media Arrangement and Distribution

   • Proper layering and uniform media distribution

   • Adjustment of media thickness

   • Prevention of channeling within the filter

4. System Inspection and Initial Testing

   • Inspection of flow rate and operating pressure

   • Verification of filtration performance

   • Minor system adjustments if required

Key Outcomes

• Restored wastewater filtration efficiency

• Stable and reliable WWTP operation

• Improved consistency of treated wastewater quality

• Continued support for environmental compliance
