The Ecoflex-520CV, a diameter 520mm (20”) bigger diffuser are developed specifically for releases 1~3mm fine bubble. All materials have been selected for their ability to withstand the effects of the chemical, bio-chemical agents and 0~100°C used in aeration tank. Air can be easily through the air control orifice and integrated non-return valve into the wastewater. The air orifice design to maintain the diffuser standard airflow input prevented the max. air enter to damage diffuser membrane.
The materials of construction for both support dish and membrane diaphragm are non-corrosive and UV resistant. The support dish shall be upward facing convex plastic (Glass filled reinforced Nylon) for working without any acid dosing requirements and patented integrated non-return valve with air control orifice, designed for back-flow prevention while airflow is interrupted. The membrane which covers the dish is made of high grade EPDM resistant to the usual sewage ingredients.
