The two companies, which have been working together on projects since 2013, expect the acquisition to close during the second quarter of 2023. 

Diefenbach has been a leader in liquid-solid separation using filter presses since its founding in 1907, when the company was focused on producing presses for the olive oil industry. In the 1950s, Diefenbach expanded into the recycling and filtration of industrial wastewater. Today, Diefenbach has experience in selling and manufacturing this equipment for the mining and aggregate industries, as well as for chemical manufacturing, food and beverage processing, battery recycling, PET recycling, and wastewater treatment. 

McLanahan Corporation was looking for a partner to continue expanding its offerings in the circular economy and in recycling water from industrial processes. This will allow the company to ensure it is able to offer a more comprehensive solution to customers and industries around the world in support of these changing requirements for processing. 

"As we look toward the future, we see a growing need for wastewater and tailings management in a variety of industries as part of the circular economy," said Cory Jenson, EVP - Sales and Business Development at McLanahan. "Every industry is being challenged to use less and less water and to recycle the water they are using. This acquisition offers significant synergies to McLanahan's existing tailings solutions in mining and aggregates, which continue to remain a critical part of McLanahan's product offerings. This new partnership allows us to offer a more competitive solution to our tailings partners around the world."
