Although this wet/wet-dry technology has been utilized for several years in unitary packaged towers for both plume abatement and water conservation applications, this is the first large scale installation designed specifically to reduce troubling plume in a large scale field-erected counterflow cooling tower. Using one cell of the existing tower as a plume abated pilot over several winter months, the owner was able to demonstrate the benefits of the technology to all stake-holders, including local authorities, neighbors and corporate leadership. Acceptance of this wet-dry technology opens up new opportunities for the retrofit of existing cooling towers, as well as easier siting and faster permitting of new plants in densely populated areas where plume abatement and water conservations are key issues.
