Dr. Mattes is one of the world’s leading experts on the design, construction and operation of a major kind of anaerobic bioreactor: Biochemical Reactors (BCRs).

Dr. Mattes is also an expert in the remediation of arsenic.

Dr. Mattes majored in Geomicrobiology at the University of Guelph. The focus of his research involved biological methods for the removal of arsenic and the specific role of iron in the process. Al began his research and work in the field of phytoremediation (bioremediation using plants) and continued with work directed at the remediation of contaminated sites and the removal of dissolved metals and metalloids from contaminated soils and water.

Dr. Mattes led the team that built and operated the demonstration scale, BCR-based engineered bioreactor system at the site of the Teck Cominco lead zinc smelter in Trail, BC. This system included two BCRs designed by Dr. Mattes. For a period of 14 years (five years summer and winter) these bioreactors and other EB System Cells efficiently reduced high concentrations of dissolved zinc, cadmium and arsenic in leachate from a landfill to trace levels. The BCRs were able to withstand high shock loads and demonstrated year-round operational capability.

Dr. Mattes has also worked as a consultant for many other projects designing systems for research and for treatment of similar dissolved metal contaminated streams such as those containing chromium, molybdenum, nickel, copper, and iron.

Currently Dr. Mattes is the chief scientist overseeing a system designed to examine the dynamics of acid mine drainage and changes in the bacterial community structure with changing temperatures. He is also working with ETDC to design a new portable arsenic filter for potable water.
