McMahon is recognized as a leader in applying new technology to biosolids management.  We are pioneers, and have been credited with many ‘firsts’:

• Nation’s first and world’s largest Auto-thermal Thermophilic Aerobic Digester (ATAD)
• Wisconsin’s first Two-staged Thermophilic / Mesophilic Anaerobic Digester (TPAD)
• Wisconsin’s first reed sludge storage beds
• Wisconsin’s first vertical screw press for biosolids dewatering

McMahon works with municipalities to develop the most efficient, cost-effective solution that will allow for the beneficial reuse of biosolids.  Additionally, our wastewater design team is well-respected for our knowledge and experience in renewable energy and cogeneration applications, including digestion projects for manure and ethanol by-products.
