What is an Aerotor and how is it different from a normal RBC (Rotating Biological Contactor) and who came up with the idea?

Thank you for the question.  The BMS Aerotor is actually a next generation RBC, with all the advantages of traditional RBCs such as low maintenance costs and power requirements with none of the disadvantages such as one sided growth placing eccentric loads on the shaft, flow bypass in shock loading conditions and lack of aeration...

Do you have any pictures of a sewage or a wastewater treatment plant that Butler Manufacturing Services worked on before and after an upgrade?

We certainly do, you can find 12 pictures of a rural 50 PE wastewater treatment plant that BMS recently upgraded below.  It includes a BMS BL500 Blivet Package Sewage Treatment Plant, control panel and flow meter.  The site contained a lot of spoilage which had to be removed along with other civil works.  Also some innovative grading of the ground avoided the need to install lifting pumps as was originally planned, saving money and maintenance in the long and short term.  This finish of the site is excellent and blends into the small rural community.  BMS can provide a full design and build excellent value fully installed package sewage treatment plant.  If you have any site that we can help you with please contact us.
