Abstract: Disclosed is a method for cleaning aeration elements (1) provided with pores or bores in aerated basins (2) of wastewater treatment plants or water treatment plants. The aeration field (4) formed by the aeration elements (1) and the pipes (3) connecting said aeration elements to each other is completely filled with a cleaning agent in a fluid form by applying pressure that is high enough to send said cleaning agent through the pores or bores of the aeration elements (1). After applying the cleaning fluid on the pores or bores of the aeration elements (1) for a variable amount of time, the aeration field (4) is emptied again. In a further optional cleaning step, the aeration field (4) is cleaned once again with a rinsing fluid, preferably water. Also disclosed are the use of an alkaline cleaning agent with a pH value of at least 10, preferably 12, and advantageous compositions of the cleaning fluid used for cleaning aeration elements.

Abstract: In an aerobic waste water treatment process, air is released through a network of pipes with fine pored outlets. The air is pre-moistened esp. by water in aerosol form with droplets in the range 0.1 (m to 20 (m or as steam. The air is pressurised within the distribution tubes to at least 5000 kPa. The air is intensively mixed with water in a fall pipe (5) and/or distributor pipe (6) forming part of the continual air feed system to the treatment basin. Prior to its introduction, the water is desalinated by evaporation, catalytic action, anionic-exchange or reverse osmosis. The discharge of water aerosol particles is regulated by measurement of the air relative humidity within the system.
