Project results phase 2

Based on the laboratory investigations and literature study ,the design parameters for the RAZone process have been defined. These are parameters that have significant impact on the performance of the RAZone process and consequently on the system footprint. Although there are a range of factors to be considered,  the consortium has agreed to focus on 5 major parameters in the design of the RAZone prototype. These include particle size, particle-bubble attachment efficiency, residence time, bubble concentration, and bubble size. Further to this, a series of jar tests using waste water samples from Salmar. The tests revealed that the largest bulk of particles have diameters in the range of 5-15 ยต. Therefore, effective management of water quality in RAS requires removal of the finest particles.  There is also a need for measurement of particle size distribution in the trials to be run. For this, 3 alternative methods are being evaluated.

Parallel with the development of the treatment process, the control system is being designed, involving development of a fully functional control software and hardware. The main control items are ozone production and dosage including potential fault and operational messages to operator cellular, reaction processes as well as logging of input and output signals.
