LAWPCA nears completion of anaerobic digesters and cogeneration plant

摘要

In April, I had the pleasure of visiting the Lewiston-Auburn Water Pollution Control Authority (LAWPCA) in Maine for a biosolids composting workshop, sponsored by JETCC. The workshop was well run and informative. One highlight was a tour of the new anaerobic digester and cogeneration infrastructure, which is under construction at the Lewiston facility. Mac Richardson, long-time superintendent, NEBRA member and forward thinker gave a spectacular tour to workshop attendees. The two new digesters are nearing completion, and the flexible membrane biogas storage tank was inflated and almost ready for use. Sparks were flying and there was an undercurrent of excitement as the hard-hat-clad workers hurried about their business.
