A new wastewater treatment plant was officially put into operation on the territory of Ellatzite Mine Complex at the beginning of 2026.

The facility has adopted a cutting-edge technology developed by the German company EnviroChemie, based on its EnviModul system. It provides an energy-efficient and resource-friendly solution for mine wastewater treatment through simultaneous removal of solid particles and heavy metals. The process combines physico-chemical treatment using four types of specialized reagents. The resulting sludge is treated in a combined module for final sedimentation and thickening. The system is designed to handle peak loads caused by heavy rainfall or snowmelt, ensuring reliable operation even under extreme conditions.

The new wastewater treatment plant occupies an area of 4,336 m2, in close vicinity to the existing wastewater treatment facility applying a technology of the Japanese company MMTEC. The existing WWTP was commissioned on the mine site in 2014.

The new WWTP consists of modular units, with a current capacity to treat up to 100 l/s of contaminated waters (four modules for chemical treatment of water at 25 l/s each), with the option for gradual expansion up to 250 l/s (ten modular units).

It is the third wastewater treatment plant that has been built on the territory of Ellatzite Mine Complex. The new facility provides better protection of the River Malak Iskar in compliance with the applicable regulatory requirements. The investment reflects Ellatzite-Med’s long-term strategy to achieve higher standards in environmental protection, sustainable resource management, and responsible water management.
