Problems solved by technology

This prevents the use of small-sized carriers with a large area per unit volume, since a corresponding reduction in the mesh size of the mesh would impair the air supply and possibly lead to blockage of the openings

Embodiment Construction

[0017]As shown, the bioreactor 1 of the present invention comprises a tubular vessel part 2, which is preferably circular or elliptical in cross-section. Said container part 2 is provided with inlet means 5 for the water to be purified and outlet means 6 for the purified water, and means 4 for supplying a fluid containing the reaction gases required for the purification process, preferably in such a way that the water to be purified Bubbles containing reactive gases are generated to supply, for example, the air required for an aerobic purification process in the form of air bubbles from which the air dissolves into the water to oxidize the water to be purified for bacterial activity. The fluid may also consist of pre-aerated water in which the air is present in the form of air bubbles and / or in a pre-dissolved form to provide oxygen-enriched water. In said case, described by way of example only, the inlet means 5 and outlet means 6 for water are arranged at longitudinally oppo...

Abstract

The invention relates to a bioreactor (1) for the purification of waters, said reactor comprising a cross-sectionally essentially circular or elliptical tank section (2) provided with inlet means (5) for water to be purified and outlet means (6) for purified water. The tank holds thereinside carrier material (3) on which a biofilm may develop. The tank is further provided with means (4) for supplying a fluid which contains a reaction gas required by the purification process, such that the water to be purified develops gas bubbles containing a reaction gas. The tank section is adapted to be essentially full of water during the purification process. The fluid supply means (4) are disposed on the tank wall and the reactor comprises control means for operating the fluid supply means in such away that a spinning motion of the carrier, the water, and at least some of said reaction-gas bearing bubbles is effected thereby around a rotation centerline passing essentially through the tank 's cross-sectional center. The control means are adapted to optionally effect a deactivation of the fluid supply means at desired times and / or a replacement of the fluid with an oxygen-free fluid for providing an anaerobic process. The invention relates also to a method for the biological purification of waters in a bioreactor.

Description

technical field [0001] The invention relates to a bioreactor for water purification, said reactor comprising a container part of substantially circular or elliptical cross-section, said container part being provided with inlet means for the water to be purified and outlet means for the purified water, said The container containing the carrier material on which the biofilm can form is further provided with means for supplying the air required for the aerobic purification process. [0002] The invention also relates to a method for the biological purification of water in a bioreactor comprising a container part of substantially circular or oval cross-section provided with inlet means for the water to be purified and purified water With outlet means, said container contains a carrier material on which a biofilm can form, said container being further provided with means for supplying the air required for the aerobic purification process.
