Oxygen micro bubble diffuser for aeration water treatment equipment machinery
Description
Feature
● The rubber diaphragm is made of imported EPDM rubber, which is anti-aging, corrosion-resistant, durable and has a long service life.
● The stepped sealing structure effectively prevents the diaphragm from falling off.
● The thickening of the peripheral area of the diaphragm has sufficient extension compensation, and can rebound freely, avoiding the tearing of the diaphragm due to stress concentration.
● The double check design, the double function of the non-porous area in the center of the diaphragm and the internal check valve, effectively prevent sewage from entering the pipeline system.
● The unique hole-opening technology makes the bubble release of the aerator uniform and the resistance loss is small.
● The air bubbles are dense, with high efficiency of oxygen utilization and oxygenation capacity.
● The diaphragm has strong self-cleaning property and strong anti-clogging ability.
● The general standard 3/4″ (English system) threaded interface can adopt threaded connection or soft connection, which has good interchangeability.
● It can withstand high temperature up to 100℃ and can be used in deep pool aeration system.
Application
The microporous aerator is suitable for aeration and oxygenation in various sewage treatment.
