Recovery of Struvite from Municipal Wastewater for Acid Mine Drainage Treatment

The North-West University has developed a method in which municipal wastewater is treated to remove ammonia and phosphate while simultaneously recovering struvite as a byproduct. 

Struvite is used to reduce the acidity of acidity of the acid mine drainage water which leads to precipitate metal pollutants. This innovative solution effectively addresses the challenge of acid mine drainage and industrial wastewater pollution, providing a comprehensive approach to environmental care and public health protection. With its versatility in treating various sources of pollution, including acid mine drainage from coal and metal mining activities, the technology showcases a significant breakthrough in sustainable water management. 

By delivering clean water while minimising environmental impact, it sets a new standard for responsible water treatment practices.

Technology Benefits

• The process is environmentally friendly.
• The process is cost-efficient compared to traditional techniques.
• The process can also recover both ammonia and phosphates from wastewater.
