A system for use with an inlet of a gas turbine through which airflow toward the gas turbine proceeds is provided and includes a first stage to remove primary aerosol droplets from the airflow by coalescing the primary aerosol droplets into secondary aerosol droplets, which are larger than the primary aerosol droplets, and to remove solid particulates from the airflow, a second water tight stage, disposed downstream from the first stage, to prevent the secondary aerosol droplets and aqueous solutions of deliquesced particulates, which are not removed by the first stage and which are re-released into the airflow from the first stage, from proceeding along the airflow and to remove solid particulates not removed by the first stage from the airflow, and a third water removal stage, disposed downstream from the second stage, to remove from the airflow the remaining secondary aerosol droplets leaking from the first and second stages.

1. A system for use with an inlet of a gas turbine through which airflow toward the gas turbine proceeds, the system comprising: a first stage to remove primary aerosol droplets from the airflow by coalescing the primary aerosol droplets into secondary aerosol droplets, which are larger than the primary aerosol droplets, and to remove solid particulates from the airflow;a second water tight stage, disposed downstream from the first stage, to prevent the secondary aerosol droplets and aqueous solutions of deliquesced particulates, which are not removed by the first stage and which are re-released into the airflow from the first stage, from proceeding along the airflow and to remove solid particulates not removed by the first stage from the airflow; anda third water removal stage, disposed downstream from the second stage, to remove from the airflow the remaining secondary aerosol droplets leaking from the first and second stages. 2. The system according to claim 1, wherein the first stage comprises a coalescing filter utilizing depth loading media. 3. The system according to claim 2, wherein the secondary aerosol droplets have diameters of at least 20 microns. 4. The system according to claim 2, wherein the solid particulates removed from the airflow by the first stage have diameters of at least 5 microns. 5. The system according to claim 1, wherein the second stage comprises a water tight filter mounted in the inlet at an oblique angle with respect to a direction of the airflow. 6. The system according to claim 5, wherein the water tight filter comprises fiberglass and/or a hydrophobic coating or layer, which is impermeable to water but allows air to pass through. 7. The system according to claim 1, wherein the remaining secondary aerosol droplets leaking from the first and second stages and removed from the airflow by the third water removal stage have diameters greater than 20 microns. 8. The system according to claim 1, further comprising a weather hood disposed upstream from the first stage to provide for protection from rain. 9. The system according to claim 1, further comprising an anti-icing system, including any one or more of a hot water coil, a steam coil or hot compressed air, disposed upstream from the first stage to prevent downstream ice formation. 10. The system according to claim 9, further comprising an upstream vane separator, disposed downstream from the anti-icing system, to remove a majority of aerosol droplets having diameters greater than 20 microns from the airflow. 11.
