Aquastrip are plate-type membrane aerators designed for fine bubble aeration processes in sewage sludge treatment systems. Plate diffusers are large surface blocks anchored directly to the bottom of the tank that consist of a support frame made of AISI 316Ti or PVC stainless steel, with a 0.6 mm polyurethane membrane micro-perforated with 400,000 holes per m2. High coverage provides a particularly low specific airflow, allowing very small and evenly distributed bubbles with consequent high oxygen transfer efficiency. System features make it ideal for use in intermittent aeration applications.
