Smart Air Injection (SAI) for Sewage Treatment Plants
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 Energy-efficient
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. Odourless
Closed system with integrated cleaning function.
