Abstract
A system for collecting, treating and disposing of waste fluid includes a station that features transfer, flushing and mixing pumps as well as a bowl that holds the waste fluid. The waste fluid is collected in a container mounted on a cart. The cart container connects to the station so that the waste fluid is transferred from the cart to the station bowl by the transfer pump. The flushing pump has an inlet that communicates with a source of water and a disinfectant dispenser. The flushing pump is used to flush both the cart container and the station bowl, the latter of which communicates with a drain system. The flushing pump also delivers disinfectant to the waste fluid in the station bowl. The inlet and outlet of the mixing pump communicate with the bowl so that it mixes the bowl contents. Buffer is provided to the circulating waste fluid until the pH level drops to a predetermined level.
