We provided a solution with a key advantage; treat the wastewater to extract the methane burned in the generators, reducing consumption of electricity from the public grid.

They gave us brand-new machines and we paid a litte bit every month. So, it's like work and pay; you work and get your money and then use a small amount to pay for the machine. We are grateful to Mantrac.
