>Product Features
( Utility Model Patent No. for Aeration Hose Support: ZL 2008 2 0300465.9 )
·1. This product is a flexible tubular aerator made from chemical fiber-reinforced modified plastic material;
·2. The entire circumference of the hose is perforated for aeration, producing medium and fine bubbles in water, with slow bubble rise speed, uniform air distribution, and high oxygen utilization rate;
·3. The hose expands during aeration and is flattened by hydrostatic pressure when not in use, which to some extent prevents sludge backflow;
·4. The hose wall thickness is only 2mm, with short and straight air channels, resulting in low air pressure loss;
·5. The air holes are elongated narrow slits, with variable width within a certain range;
·6. The inner surface of the hose is very smooth, making it difficult for biofilm to adhere;
·7. No air filtration equipment is required; aeration can be stopped at any time, and regardless of the duration, clogging will not occur;
·8. Easy assembly with low requirements for installation flatness; the air supply pipe and aeration pipe are integrated at the bottom of the tank, eliminating the need for additional piping equipment, and the price is lower than other microporous aerators;
·9. Good resistance to acids and alkalis;
·10. Can be coiled for packaging, small volume, convenient for packaging and transportation.
>Design Reference
·1. Design technical parameter values: aeration rate 5m3/m·h, oxygen utilization rate 12%;
·2. The hose is generally placed 200-300mm above the tank bottom, with a spacing of 500mm between hoses, which can be designed based on water quality, removal load, and oxygen demand;
·3. Within a certain range, multiple aeration hoses (generally no more than 10) can be connected to the same air distribution pipe as a group, controlled by one valve. To ensure uniform air supply for all hoses in the group, the diameter of the air distribution pipe should be appropriately enlarged;
·4. When using aeration hoses in activated sludge processes, especially in Sequencing Batch Reactor (SBR) treatment systems, it is recommended to include sludge discharge measures in the design to allow for the removal of sludge from the pipes when necessary.
