Harita Nickel through one of its subsidiaries, PT Halmahera Jaya Feronikel (HJF), recently held a drill or training to comply with the quality standards of the Waste Water Treatment Plant (WWTP). Drill conducted by the Department of Health, Safety & Environment (HSE) aims to improve the preparedness of the team on duty in the field.
Dressed in gray uniforms complete with masks and vests along with supporting equipment, the team conducted a drill in the employee mes WWTP area. The team simulated the steps that need to be taken when they found the content in the waste exceeded the established quality standards.
In this drill, the scenario involved the sampling team discovered the ammonia levels in the wastewater outlet exceeded the quality standards. Following this, swift action was taken to address the situation. The sample was immediately sent to the laboratory for validation. If the results confirmed the breach of the quality standards, the operational team would be notified via internal radio communication for further action.
Environment Supervisor HJF Bobby Loys Lengga explained, “Validation was needed to ensure the next actions taken were based on reliable data. Following this, control procedures for handling the situation were directly implemented.”
These procedures included shutting the main valve to prevent further wastewater flow. The HSE team then prepared to use nutribac, a substance designed to accelerate the growth of bacteria or microbes that aid in wastewater treatment, ensuring the WWTP operates efficiently and meets the required water quality standards as per applicable regulations. Additionally, the emergency blower was activated to support the aeration process in the WWTP.
“By shutting off the flow and injecting nutribac, we ensure that the treatment process can resume optimally, accelerate the reduction of ammonia levels, and restore the water quality to meet the standard,” said Bobby.
Once ammonia levels return to normal and align with the standards, the team will continue to monitor and conduct further sampling, both in the field and at the laboratory, for validation.
Bobby further explained that drill like this are crucial for maintaining the team’s readiness to handle unforeseen situations. “This kind of training is essential to enhance the team’s preparedness. Moreover, we want to ensure that every member knows exactly what actions to take if an emergency situation arises,” he stated.
Through this drill, HJF demonstrates its strong commitment to effective and responsive environmental management. This drill not only serves to prepare tactical personnel for field emergencies but also reinforces the reminder that maintaining environmental quality is an integral part of the company’s operations and responsibilities.
