Abstract
Abstract Apparatus for sequentially evaporating a liquid disinfectant and a neutralizing agent at constant flow rates and feed level. The apparatus includes sealed containers for the liquids to be evaporated; the containers communicating with open evaporating vessels via conduits which are provided with bevel-cuts at the ends immersed in the evaporating vessels, valves positioned to control the flow through the conduits, absorbent pads extending above the level of liquid in the vessels, and a blower for directing a flow of heated gas across the absorbent pads.
