ABSTRACT:
A method and apparatus for deodorizing the pungent airflow exhausted by a vacuum pump system while evacuating foul smelling liquids or liquid-solid mixtures from a holding tank such as a septic tank or a grease trap. A manifold is connected to the vacuum pump to receive the airflow exhausted by the vacuum pump. At least one nozzle is attached to the manifold so that a distal end of the nozzle extends into the airflow passing through the manifold. A reservoir supplies a concentrated liquid deodorizer to the nozzle during operation of the vacuum pump. The liquid deodorizer is dispersed by the distal end of the nozzle and mixes with the airflow within the manifold to deodorize the airflow before the airflow is exhausted to the ambient atmosphere. The distal end of the nozzle which extends into the airflow is tapered to substantially atomize the liquid deodorizer and enhance the mixture of the liquid deodorizer with the airflow. The deodorizing method and apparatus may be installed on any existing vacuum pump system.
