MIND ID is consistent in applying the best systems for water management in each of its strategic projects. This is not just about meeting operational production standards, but also part of a long-term strategy to preserve the environment.
This is comprehensively implemented at the Smelter Grade Alumina Refinery (SGAR) in Mempawah, West Kalimantan, which is operated by PT Borneo Alumina Indonesia, a joint venture between PT Indonesia Asahan Aluminium (INALUM) and PT Aneka Tambang Tbk (ANTAM). SGAR has utility facilities ranging from a production wastewater treatment station to a water intake station.
MIND ID's Corporate Secretary, Heri Yusuf, emphasized that SGAR is one of the national strategic projects, and MIND ID strives to ensure that every system applied is the best system, including in terms of water management.
"Through an integrated water management system, we aim to reduce surface water consumption, while ensuring that the water used can be treated, recycled, and returned to the environment with quality that meets standards," he said, as quoted in a written statement on Wednesday (January 8, 2025).
Heri explained that the integrated water management process begins with the treatment of raw water at the Intake Water Station, distribution and storage through the River Water Regulating Pool, and purification at the Water Purification Plant.
The wastewater generated from production is processed at the Production Wastewater Treatment Station using the latest technology to ensure its quality before being recycled or returned to the environment.
Heri Yusuf added that the success of the water management system at SGAR is closely linked to the application of advanced technology and a commitment to continuously improve operational efficiency.
"The principles of reduce, reuse, and recycle form the foundation of every step we take in managing water at SGAR. This approach not only helps us meet environmental standards but also ensures that water resources are preserved for the sustainability of operations in the future," he explained.
SGAR also optimizes the use of rainwater through the Rainwater Collecting Pool, where the collected water is treated and reused for various operational needs.
Domestic waste from daily activities is processed at the Domestic Sewage Treatment Plant, which applies a series of anaerobic, anoxic, aerobic, and precipitation processes to ensure that the wastewater is free of harmful contaminants before being discharged into water bodies.
In addition, the Demineralized Water Plant at SGAR ensures the availability of high-quality water to support production processes that require specific standards. Through demineralization technology, the water produced is free from mineral salts and ready to be used in various production activities that require high precision.
