Length of tubular aerator and its debugging method

The tubular aerator consists of a membrane tube, a liner, a connector, a plug and a clamp. The gas supply main pipe and the pilot gas groove can be opened with a rubber film for microporous aeration. The utility model has the advantages of simple structure, high oxygen utilization rate, reliable performance and no blockage of pores. The length of the tubular aerator can be determined according to user needs, and the conventional ones are 580mm, 800mm and 1000mm. Extrusion or compression molding is used for lengths below 580 mm, and extrusion molding is performed for lengths greater than 580 mm.

The tube of the tube aerator is perforated at a pitch of 1.5 mm and 2 x 2.5 mm to produce uniform microbubbles having a diameter of 1-3 mm. There is a 15mm long non-porous area at the top of the membrane tube. When the gas supply is interrupted, the membrane immediately returns to its original state, and the air inlet is automatically prevented from backflow.

After the installation of the aeration system is completed, the water test is carried out in the aeration tank, and the water depth is submerged by the aerator 10-20 cm. Start the fan and check the tightness of each aerator by aeration. If an aerator is not installed tightly, after a brief aeration stop, bubbles will appear in the tight place. The aerator should be fully aerated for 24 hours before measuring the oxygen supply. The maximum ventilation should be limited to 30m3/(h/root).

The air of the inlet aerator must be filtered, and the temperature of the gas entering the aerator should not exceed 80 ° C. If it is higher than this temperature, the requirement should be submitted to the manufacturer. If the aeration tank is not used immediately after installation and commissioning, please inject at least 1m of deep clean water into the aeration tank until the aeration tank is officially used.www.khnwatertreatment.com
