Smart Air Injection
Long distance pumping
Smart Air Injection (SAI) is a customized package unit with many varied applications. The innovative combination of progressive cavity pump and compressed air conveying results in a low-pressure level in the conveying pipeline. This results in an extended service life and reduced investment and operating costs.
In the environmental sector, SAI transports sewage sludge up to 1,000 meters by means of compressed air and lubricant injections. This allows the sludge to be transported easily and with particularly low friction and thus energy-efficiently.
Benefits and Features
Total energy consumption reduced by up to 72% compared to conventional conveying technologies.
Lower investment costs
Long service life and low investment costs due to less expensive pipes and fittings with low pressure stability (PN 10).
Maintain in Place
Easy Maintenance Concept: Maintenance-in-Place possible - Smart Conveying Technology for rotor/stator replacement with minimal space requirements in less than one hour.
For long distances and height differences
Long transport distances of up to 1,000 meters and flexible overcoming of changes in direction and differences in height.
Low pressure requirements
Increased component lifetimes and up to 88% savings in maintenance costs due to extremely reduced discharge pressure of only 2-4 bar.
Easy to control
Control and monitoring of all functions via the SAI controller and easy integration into all automation and control systems.
Closed system with integrated cleaning function.
Ensures optimal feeding of the media.
Connected to the upstream dewatering machine with integrated filling level sensor and pump speed.
Frequency inverter with integrated PLC.
Square feed hopper with vertical walls and rotating ribbon screw ensures excellent discharge and the optimized addition of viscous sludge.
Boundary Layer Injection
To reduce friction losses in the pipeline.
Connection for injecting lubricants and compressed air.
For storing and releasing compressed air from the upstream compressor.
Smart Air Injection is a customized system solution from SEEPEX, which conveys sludge with a dry solids content of 20-40% over long distances up to 1,000 meters. The technology combines the innovative properties of progressive cavity pumps with compressed air dense phase conveying.
In our half-hour webinar we will show you the many advantages of the intelligent SAI system solution for conveying dewatered sludge in wastewater treatment plants. Our Global Product Manager SAI, Dr.-Ing. Stephan Mottyll, describes the energy-efficient SAI conveying concept, which can save up to 80% of operating costs. In addition, he shows areas of application and functions and explains the enormous savings potential of pneumatic compressed air conveying compared to conventional conveying methods on the basis of numerous practical references. It's worth taking a look.
