Do we have to schedule the cleaning of the diffusers on a regular basis? How are they cleaned?
A large number of our AEROSTRIP installations have the diffusers running in an on-off mode (e.g. for denitrification) and do not require any cleaning. For plants that are running at a constant airflow, we recommend the use of a daily relaxing cycle, (i.e., turning the air flow off and releasing the air from the system for a few minutes per day and then restarting). This relaxing cycle squeezes deposits out of the pores before they have a chance to accumulate. For some industrial plants where chemical deposits build up even with the relax cycle, we have successfully dosed an organic acid feed into the air supply for a day or two, every other year, while the basin is online.
