Neutralizing stations designed to neutralize glutaraldehyde and some other aldehyde-based high-level disinfectants such as ortho-phthalaldehyde (OPA) before disposal into the drain. These stations typically consist of a neutralization tank, a sensor to detect when the tank is full, a pump, and input/output tubing for connection to the disinfectant solution source (e.g., a disinfector) and to the drain, respectively. The station tank receives the disinfecting solution after use (i.e., the spent solution); then the solution is mixed with an appropriate neutralizing agent such as glycine that converts it into a non-toxic product. When the tank is completely full, an integral pump automatically delivers the neutralized solution down the drain to the sewerage system. Glutaraldehyde/aldehyde-based disinfectant neutralizing stations are intended to facilitate the neutralization process following existing standards, protecting both the operator and the environment from the disinfectant vapors.
