Spent Management: Waste to Product The LCTM framework has resulted in a significant breakthrough in the management of spent acids. The traditional process for treating spent acids was ineffective in removing process impurities, which limited its application. Our newly designed spent acid purification process utilises a two-step methodology. The first stage involves using a substrate medium to eliminate bulk impurities from the spent acid, followed by steam stripping in the second stage. This innovative approach has led to substantial improvements in the quality of spent acid, achieving the following results: 

COD: From 12000 to <1000 mg/l Nitric content: 10000 PPM to < 50 PPM

These process enhancements have enabled us to use spent acid in downstream manufacturing, thereby reinforcing our commitment to environmental stewardship.
