Abstract: Improved photo-oxidation apparatus for purifying water, which has at least two reaction chambers each connected by water passageways with neighboring chambers, and which has in each chamber, sources of ultraviolet light dipped practically vertically into the water to be treated and fixed by holders placed above the surface of the water. The apparatus is also equipped with nozzles through which gas, usually containing oxygen, is supplied, and with inlets for oxidizing agents, catalysts or photosensitizers in at least two of these chambers or sections.

Abstract: A method for biologically purifying waste water which produces substantially no excess waste sludge is provided. In this method, a waste water containing biodegradable substances is treated in a biological fixed film type reactor and aqueous water sludge discharged from the reactor is aerobically digested after being separated from the biologically treated waste water. The digested aqueous sludge is returned to the reactor or the upstream thereof. This method can be advantageously combined with any installed activated sludge type water purification process, to thereby substantially eliminate the production of excess waste sludge from the water purification system.
