CCS wet scrubber technology charges water and particles with opposite polarity. In the action of the scrubber, droplets and particles move continuously in relation to each other. As they approach 10 microns of separation, electrical attraction causes the particle to enter the droplet. The technology requires less than one inch of pressure drop under full load operation and it can remove fumes and gases, including HCl, HF, HNO3, H2SO4, SO2, Cl2, NH3 and others the same time as the particle.
