Planes are sprayed with the fluid by deicingvehicles.There are two types of deicer: Type I has a low viscosity<strong>and</strong> is mixed with water in a ratio of 55:45. It isheated to 85° C before being applied to aircraft. TypeIV deicer contains a thickening agent <strong>and</strong> is viscous.It is applied cold, in undiluted form.Deicer applied to aircraft at deicing points drainsalong with melted ice <strong>and</strong> snow through channelsinto underground collecting tanks. The mixture is thentaken by truck to a recycling plant for processing,where it is cleaned in a number of mechanical <strong>and</strong>chemical stages <strong>and</strong> then distilled. This process producesthe glycol-containing substance on which thedeicing agent is based. Additives are introduced tocreate type I deicer. Following lab tests <strong>and</strong> manufacturerapproval, the deicer can be used again.164
