AMHSA Altos Hornos de México
In 2006, the capacity of the plant increased to 650 liters per second. AHMSA currently uses 580 liters per second of the water treated in the plant in its industrial processes.
Since 1992, AHMSA has been implementing a program for promoting awareness and providing training regarding water usage for its employees in all of its facilities.
In 1995, a wastewater treatment plant was built for the city of Monclova, Coahuila, with a capacity of 450 liters per second, which is reused by AHMSA.
To a worldwide level, AHMSA is one of the steelworks with less water use in its processes and recognized for its high levels of regeneration.
Our efforts to save and use water efficiently are focused on:
• Decrease in the extraction of raw water.
• Greater use of treated water.
- As of 1992, AHMSA applies a program of awareness and training of personnel in water care in all its units.
- The process of modernization of the company included as one of its central requirements, the environmental improvement and high efficiency equipment in water use.
- In 1995, a sewage treatment plant was built for the city of Monclova, Coahuila, with a capacity of 450 liters per second, a flow reused by AHMSA.
- In 2006, the capacity of the plant increased to 650 liters per second.
- AHMSA currently uses 580 liters per second of the water treated in the plant in its industrial processes.
- In 1995, 30 million dollars were invested in a hydrochloric acid regeneration plant, in order to eliminate acid water discharges to local courses.
- Based on studies carried out in 2008 and 2009, investments were made in projects to use industrial water in processes, with a reduction of up to 156 liters per second of raw water.
- Currently only 2.9 m3 liters of water are used per ton of steel produced, one of the lowest rates worldwide.
- The MICARE Unit designed and applies a system of reinjection of water from mines to groundwater. Endorsed by the Mexican Institute of Water Technology (IMTA) and the South West Research Institute of Texas, USA, the system is today a national model for the reinjection of aquifers.
- With its actions of adequate use, AHMSA and its companies have avoided the extraction of hundreds of thousands of liters of water from regional aquifers.
