Fine Bubble Membrane Disc Diffusers – Evoqua: Envirex

Evoqua: Envirex - Fine Bubble Membrane Disc Diffusers - Evoqua: Envirex- Diamond S Membrane Disc Diffusers is more efficient than a typical 9" diameter diffuser, resulting in better performance and lower energy costs. The proprietary diamond punch pattern provides 10% more slits than a typical membrane, allowing more fine bubbles to be produced. Additionally, the Diamond S Plus diffuser has 45% greater tensile strength than typical membranes for durability and tear resistance and less than 9% extractable oil for improved diffuser life. The diffuser was developed as an improvement to typical membrane diffusers, and to fit other manufacturer’s pod or holder. Existing support plates and retainer rings can be reused.

Coarse Bubble Diffusers – Evoqua: Envirex

Evoqua: Envirex Coarse Bubble Diffusers are used in aerobic digesters or sludge holding tanks and offer the advantage of sealing the piping system when the air is turned off. Wideband™ coarse bubble diffusers can be used in a variety of aeration and mixing applications. Diffusers and piping are available in 304L or 316L stainless steel. SnapCap™ coarse bubble diffusers consist of an EPDM diaphragm that seals the piping system when air is turned off and can be used PVC or stainless steel piping. Ideal for tough duty applications such as grit chambers, flow equalization, channel aeration and intermittently used basins.

Floating Aerator – Aqua-Jet II Contained/Covered

Aqua Aerobics Systems Aqua-Jet II® Contained Flow Aerator is for applications which require continued operation of aeration equipment during cold weather months, but are limited because of inadequate heat sink due to process selection or environmental conditions. This aerator has proven to operate efficiently in a variety of applications, even in sub-zero temperatures.

Fine Bubble Ceramic Disc Diffuser – Sanitaire

Sanitaire - Xylem - Fine Bubble Xeramic Disc Diffusers feature an advanced design takes the proven technology of ceramic fine-bubble diffusers and makes it better, with the highest oxygen transfer efficiency compared to other ceramic diffusers – and energy cost savings of up to 30%. The higher OTE reduces the power consumption of blowers. That’s savings that pays back immediately - and year after year. One to four year payback is what can be expected when old diffusers are replaced with new Xeramic diffusers. A system utilizing Xeramic diffusers has better or comparable SOTE values to membrane-type diffusers. Therefore, Xeramic diffusers are more economical on a 20-year life-cycle period.

Retrievable Aeration with Tube Diffusers – Aqua Aeorobics

Aqua Aerobics - Retreivable Aeration - The system features fine-bubble “Retrievable Diffusers” in racks that can be lifted by a davit crane and rotated outside the basin for maintenance or replacement without taking the aerations system offline.
