NOVELTY - A waste fluid treating and disposing station includes a bowl positioned within a housing (72); a mixing pump having an inlet and an outlet in communication with the bowl so that waste fluid is circulated; a pH sensor in communication with the bowl so that a pH level of the circulating waste fluid may be detected; a container (32a, 32b) holding a supply of buffer; and a pH controller in circuit between the buffer container and the bowl so that the pH controller controls the delivery of buffer to the circulating waste fluid, the pH controller communicating with the pH sensor.    USE - The station is used for treating and disposing waste fluid i.e. cell culture waste fluid, and used in a system for collecting, treating, and disposing waste fluid (claimed).    ADVANTAGE - The station provides for a system for safely and conveniently collecting, treating, and disposing a large volume of waste fluid, and that is easy to configure and operate; and permits large volumes of waste fluid to be treated and disposed of without contact by personnel.    DETAILED DESCRIPTION - A waste fluid treating and disposing station includes a housing; a bowl positioned within the housing and adapted to receive the waste fluid from a source; a mixing pump having an inlet and an outlet in communication with the bowl so that waste fluid is circulated; a pH sensor in communication with the bowl so that a pH level of the circulating waste fluid may be detected; a container holding a supply of buffer; and a pH controller in circuit between the buffer container and the bowl so that the pH controller controls the delivery of buffer to the circulating waste fluid, the pH controller communicating with the pH sensor so that it delivers buffer to the circulating waste fluid when the pH sensor detects that the pH level of the circulating waste fluid is above a predetermined pH level. INDEPENDENT CLAIMS are also included for:    (1) a system for collecting, treating, and disposing waste fluid, comprising a waste fluid treating and disposing station; and    (2) a method of treating waste fluid comprising collecting the waste fluid in a station; adding disinfectant (i.e. bleach) to the collected waste fluid to create a solution; mixing the solution; allowing the solution to sit for a predetermined period of time; resuming mixing of the solution; detecting a pH level of the solution during the resumed mixing; adding a buffer to the solution during the resumed mixing until the pH levels drops below a predetermined level so that a treated solution is created; and draining the treated solution fluid from the station.
