I believe this initial SPICE test will only pump water, it's a test of the delivery system.
Agglomeration (coalescing of particles) is in one of the future proposed work products though: http://www2.eng.cam.ac.uk/~hemh/climate/Geoengineering_RoySoc.htm "WP1.3 Investigating agglomeration. Agglomeration rates will be key to the success of any stratospheric aerosol geoengineering attempt. If particles agglomerate too quickly, rapid fallout will be enhanced, reducing residence times. We will use the RAL-MSF rig to investigate agglomeration by running extended experiments that measure accurate particle size distributions over time." RAL-MSF is lab based though, not part of the field test.
