Process description:
Our process includes three different process steps to ensure maximized water savings and energy efficiency:
• The first stage comprises mechanical separation with GEA decanter centrifuges. Here, suspended solids are
effectively removed from the waste water stream.
• The second stage is the thermal separation with the GEA falling film evaporator. Here, dissolved solids are concentrated for their later disposal, while clear condensate is produced to feed the third stage.
This stage is especially sustainable thanks to the mechanical vapor recompression (MVR) system that powers the evaporator.
• The third stage consists of our steam reformer. This stage gives full circularity to the water recycling system. It catches waste water in a loop where it transforms into process steam. Using waste water instead of fresh boiler feed water to produce process steam allows significant water and cost savings.
