@aerzen_steve , can you share any insights?
Waiting for inputs from Steve or any other one who is experienced in this
Blowers are the heart of a biogas facility, as they supply energy in the form of pressure to the biogas to transport/move it from its source, i.e., the production system (digester or landfill) to the various consumers (boilers, engine, turbine, flare, plant, and biomethane cleaning and production equipment). All of these consumers (machines, equipment, and technologies) require a certain amount of energy in the biogas in the form of pressure for proper operation.
Therefore, they are typical and important machines in these types of biogas facilities, where the biogas generally has low pressure. These machines, connected to the piping system, constitute the bloodstream of a biogas facility.
There are different types of blowers depending on their operating principle. The most commonly used blowers in biogas facilities are side channel, centrifugal, and rotary piston blowers (root).
Several parameters and factors must be taken into account when selecting a blower, such as biogas flow rate, required pressure, and type of biogas installation, among others. Proper selection of the blower will ensure proper operation of the biogas installation. And remember that this type of machine must comply with ATEX certification.

@BGasTech Thank you very much for your detailed response. The images you used n your response, are these projects your company worked on?
Good morning, Natalia.
Yes, these are two of the projects we developed for two WWTP in Madrid, Spain. The Butarque WWTP and the Alcala Oeste WWTP, which, in addition to the biogas cleaning system, included blowers to capture, clean, and send the biogas to engines. We have done two more projects of this type. One for the San Jose WWTP in Costa Rica and the other for the Sagunto WWTP in Valencia, here only the Engineering, Spain. In addition to supplying the technology and equipment for biogas cleaning, we also provided the engineering for all of these plants. Below you can see photos of complete plant
Joaquin, thank you very much for sharing this information. This is so cool
