Diffusers are customarily arranged in a grid pattern over the bottom of the pond, with the number of individual diffusers determined by the oxygen transfer rate of the diffuser and the oxygen consumption rate in the water. Oxygen transfer increases with smaller bubble size, deeper bubble release point, and higher oxygen content in the bubbles. AEROSTRIP® Fine Bubble Membrane Diffusers offer numerous advantages, when compared to other fine bubble diffusers. Between 4.0—5.0 kgO2/kW transfer efficiency; Ultra-Fine bubble size provides of highest transfer rates; Oxygen transfer efficiency up to 60%; Non clogging design; PU membrane; long life (greater than 12 years) Guaranteed standard oxygen transfer efficiency (SOTE) up to 10%/m (3%/ft) SWD Membrane service life of 10 – 15+ years while maintaining peak perfromance Perforation allows for intermittent operation and an automatic flex cleaning cycle Evenly-spaced, floor mounted diffusers use the entire process volume oxygen-transfer efficiencies of fine-bubble aeration systems remain, par ticularly by reducing mean bubble sizes and reducing E? requirements.

Diffused-aeration systems are common in wastewater treat Our Bubble Tubing® has very high SAE (Standard Aeration Efficiency), SOTR (Standard Oxygen Transfer Rate), SOTE (Standard Oxygen Transfer Efficiency) performance ratings. The Bubble Tubing® linear air diffuser has two opposite rows of fine holes 1.3 cm (1/2″) apart along the entire length of the tubing. was to determine the oxygen transfer efficiency as a function of diffuser submergence. The ADS system is used in lagoons and other applications requiring only a low air flow rate. The tubing is composed of a virgin polyethylene (containing>2% Carbon Black) with
