(WO9609987-A2)      A process and assembly to break down and treat pollutants in water effluent which are difficult to degrade with purely biological means. The novelty is that: (a) a gas contg. ozone is generated (18) from a gas contg. oxygen; (b) the gas contg. ozone is introduced and mixed into the circulating water; (c) the ozone-water mixt. is introduced into a reactor vessel (24) in which the pollutants are de-oxygenated, and (d) the water effluent is passed through an aerobic treatment vessel (8) which then further breaks down the de-oxygenated pollutants.    USE -   The process and assembly treat and process water effluent contg. pollutants such as toxic substances from refuse tips and industrial effluent e.g. chlorinated hydrocarbons, dioxins, pesticides and dyes.    ADVANTAGE -   The process and assembly sharply reduce the cost of waste treatment by minimising requirements for plant and energy, compared with previous processes, by maximising the efficient use of oxygen.
