AEROSTRIP® is a fine bubble diffuser used in wastewater treatment that produces tiny 1mm bubbles which maximises oxygen mass transfer and hence utilizes less energy than any other diffuser.
Globally there are over 2000 references and here in Australia, there are 30+ references with a total of 15000+ individual AEROSTRIP® DIffusers in operation.
The oldest Australian reference has been in operation for 11 years without the need for replacement. This is followed by two further references that are 9 years old, both of which are still operating on the original diffusers.
Inspections have shown that less than 1% of the diffusers have failed and that the unique proprietary polyurethane blend has proven its superior longevity over EDPM and Silicone. This is a significant cost benefit to the end users as circular type units require replacement every 4 – 5 years.
Diffuser fouling is controlled via the incorporation of a blow down cycle to relax and then expand the membrane several times per day.
Chemical cleaning every 2 to 3 years with acetic acid cleans any organic fouling and returns the oxygen transfer efficiency to as new levels. This was seen at several sites that Hydroflux recently inspected.
Together with the energy saving benefits, AEROSTRIP® has proven to be the preferred choice by numerous water authorities and industrial clients around the world.
