The saturator system is the most cost consuming part in DAF operation and optimization of the used methods is of great economical interest. An ejector-based system for use in a pilot plant was evaluated with novel air collecting methods. Three ejectors with increasing size were examined and a relation between ejector water velocity and a […]
