Revolutionizing Wastewater Treatment in Meat Processing with Pedro Gil’s SPG Screw Compressor

This technical case study explains how Pedro Gil helped a major meat processing facility optimise the performance of its wastewater treatment system through advanced screw blower technology.

The plant required a reliable air supply solution capable of supporting continuous aeration while improving energy performance and reducing the operational limitations of its previous blower system.

By integrating Pedro Gil’s SPG oil-free screw compressor, the customer was able to move from traditional positive displacement technology to a more efficient and reliable solution for industrial wastewater treatment.

Key project details

•  Industry: Meat processing / pig slaughtering facility
• Application: Wastewater treatment aeration
• Technology installed: Pedro Gil SPG series oil-free screw compressor
• Previous technology: Traditional positive displacement blowers
• Main benefits: Energy efficiency, noise reduction and improved reliability
• Objective: Modernise the aeration system and optimise wastewater treatment performance

In meat processing facilities, wastewater treatment systems must handle demanding operating conditions and maintain stable performance over long duty cycles. Aeration plays a central role in biological treatment, but it can also become one of the most energy-intensive parts of the installation.

The customer was operating with traditional positive displacement blowers, a technology that can provide robust performance but may not always offer the best efficiency profile for modern wastewater treatment requirements.

The plant needed a solution that could improve the efficiency of the air supply system, reduce noise levels and support reliable operation in a challenging industrial environment.

The challenge was to modernise the aeration system without compromising treatment stability or process continuity.

The project delivered practical improvements across the customer’s wastewater treatment operations.

Improved energy efficiency

The SPG screw compressor helped reduce the energy required for aeration, supporting lower operating costs and a more efficient treatment process.

Reduced noise levels

The new technology contributed to a quieter working environment compared with the previous blower system.

Greater operational reliability

The solution was designed to support continuous operation in a demanding meat processing facility.

More efficient wastewater treatment aeration

The SPG screw compressor helped optimise air supply for the biological treatment process.

Support for modernisation and sustainability goals

The equipment upgrade helped the customer move towards a more efficient, reliable and sustainable wastewater treatment system.

Aeration is one of the most important stages in biological wastewater treatment. It is also one of the processes with the greatest impact on energy consumption, operating costs and system stability.

For industrial facilities such as meat processing plants, choosing the right air supply technology can make a measurable difference. Screw compressors are designed to deliver efficient air supply with stable performance, making them a strong alternative to traditional positive displacement blowers in many continuous-duty applications.

In wastewater treatment, this can translate into lower energy use, improved process control, reduced noise and better long-term reliability.

Pedro Gil has extensive experience in blower and pressure technologies for demanding industrial applications, including wastewater treatment, food processing and continuous aeration systems.

Our technical approach is based on understanding each installation’s real operating conditions. This allows us to recommend solutions that respond not only to air demand, but also to energy performance, reliability, acoustic comfort and maintenance requirements.

In this project, Pedro Gil helped the customer modernise its wastewater treatment aeration system with a solution designed to improve day-to-day operation and long-term efficiency.
