BIBUS (UK) Ltd supported Saint-Gobain with a tailored landfill leachate aeration solution for a closed rural site in England, specifying and supplying Jäger TD65 tube diffusers and supporting the selection of FPZ side-channel blowers to deliver reliable, energy-efficient treatment across four existing tanks.
The Challenge
Treating landfill leachate is complex because every site has different conditions and treatment needs. Off-the-shelf equipment is not always suitable.
Saint-Gobain was developing a multi-stage leachate treatment plant for a closed landfill in rural England. The project required an aeration system that would:
The Solution
BIBUS (UK) Ltd reviewed the project requirements and specified an aeration system based on the existing tank dimensions.
The team recommended the correct number and size of aeration diffusers for each tank to achieve effective oxygen transfer. BIBUS then supplied the diffusers and supported their integration into the treatment plant.
BIBUS also helped with blower selection by connecting Saint-Gobain with specialist suppliers. Its long-standing partners include Jäger, which manufactures aeration diffusers, and FPZ, a supplier of side-channel blowers.
Why Aeration Matters
After the first stage of biological treatment, oxygen must be reintroduced to keep the treatment process working efficiently.
In a diffused aeration system, blowers supply air to diffusers installed in the treatment tanks. These diffusers release fine bubbles that improve oxygen transfer throughout the liquid.
Correctly selecting the diffuser size, quantity and layout helps improve treatment performance while reducing unnecessary energy use.
The Result
The completed aeration system was designed around the site's existing infrastructure rather than using a standard configuration. By matching the diffusers to the treatment tanks, the system provides reliable aeration while helping to minimise energy consumption.
The project demonstrates how technical expertise and collaboration with specialist manufacturers can deliver practical, application-specific solutions for landfill leachate treatment.
Working Together
Rather than simply supplying components, BIBUS supported Saint-Gobain by:
Supporting Water Treatment Projects
BIBUS (UK) Ltd supplies aeration equipment and provides technical support for water and wastewater treatment applications.
Whether developing a new treatment plant or upgrading an existing system, BIBUS can help specify suitable diffusers, blowers and air pumps to match the needs of each application.
