Sand and Carbon Filter Media Replacement

Project Overview

This project involved the replacement of sand and activated carbon filter media for a 10 m³/h demineralized water system at the plating TC2W facility of PT Suzuki Indomobil Motor Plant Tambun I. The work was conducted to restore filtration performance that had declined due to long-term operation. All activities were completed within a short execution period without disrupting plant operations. Maintaining consistent water quality for plating processes was the main focus.

Project Objective
The objective of this project was to restore filtration efficiency and ensure stable demineralized water quality by replacing worn sand and activated carbon media. The project aimed to support reliable plating operations and maintain overall system performance.

Project Scope

1. Assessment of Existing Filter Media

   • Evaluation of sand and activated carbon media condition

   • Identification of performance degradation

   • Confirmation of suitable replacement specifications

2. Sand and Activated Carbon Media Replacement

   • Removal and disposal of existing filter media

   • Internal cleaning of filter vessels

   • Installation of new sand and activated carbon media

3. Media Arrangement and Distribution

   • Proper media layering and uniform distribution

   • Adjustment of media thickness and configuration

   • Prevention of channeling inside the filter system

4. System Inspection and Initial Testing

   • Inspection of flow rate and operating pressure

   • Verification of filtration performance

   • Minor system adjustments after replacement

Key Outcomes

• Restored filtration efficiency

• Stable demineralized water quality for plating processes

• Improved reliability of the demineralization system

• Minimal downtime with no disruption to plant operations
