The Development of Ejection Reagent Input in Water Treatment Systems

The universal ejection scheme of the reagent's preparation and input is offered in this work, wherein hydrodynamic jet-mixing devices are used. Ejectors in the system act as mixing devices, batchers and cavitators at the same time. It is possible to obtain cavitation (two-phase) liquid flow mode, basing on the assessment of cavitation number. Principle scheme of the reseach unit is offered for modelling and water treatment. In this scheme the module for reagents and air ejection is used. Furthermore, the calculation of water-moderated and water-air ejectors, working in the cavitation mode, was performed on the base of empiric equations.
