Our team possesses practical experience derived from the hundreds of lime and powdered activated carbon plants that have been realised. This is how we have become recognised experts in this field over the years.
We continue to develop systematically, too, and associate this with the valuable input from highly-qualified newcomers from other fields and the fresh knowledge of young university graduates.
Together we find the best solutions. That includes your specific use case.
