Tideflex Technologies’ aeration system combines coarse and fine bubble aeration components to improve mixing and oxygen transfer while preventing backflow and clogging. The custom engineered system uses the Tideflex® TFA coarse bubble diffuser to provide rapid mixing while the company’s Tubeflex Fine Bubble Air Diffuser provides the fine bubble supplement.

Aerzen has introduced a new series of blower units, Delta Blower Generation 5. Compared with the previous generation, sound levels of the new series have been reduced considerably; on average by 6 - 8 dB(A), and in some cases even more. Special attention was given to the fact that absorption material within the silencer elements is no longer necessary and therefore not used.

Dissolved oxygen and suspended solids are two of the most important controllable parameters in any biological reactor. Stabilizing these two parameters will reduce operation costs and enhance process performance. Insite Instrumentation Group’s Model 2000 will make both of these crucial measurements. The dissolved oxygen sensor is an optical design that eliminates the need for replaceable membranes, sensor caps, cartridges, and fill solutions.

WTW has introduced the new FDO 700 IQ Dissolved Oxygen Sensor, the next generation of optical D.O. sensing technology. The sensor eliminates constraints and inherent weakness associated with first generation optical sensors and requires less maintenance. The sensor features Intelligent Membrane Technology (IQMC) - each membrane is individually calibrated, all data is stored within a memory chip permanently affixed to the membrane and transmitted when connected to the sensor.

SolarBeeTM floating solar-powered circulators are designed to provide long-distance laminar flow for mixing oxygen in wastewater ponds. The approach conserves dissolved oxygen by distributing super-saturated surface water throughout the pond, thus reducing aerators’ run time by as much as 50%. The circulators can reduce effluent BOD, TSS and ammonia. In addition, they can help solve problems involving overloading, odors and sludge build up.

BlueInGreen has introduced a new product line that can address many difficult aeration/oxygenation applications. The Supersaturated Dissolved Oxygen injector (SDOXTM) delivers large quantities of dissolved oxygen and provides the energy required to mix and distribute the oxygen into the wastewater being treated. A wide range of target DO concentrations can be achieved without bubble formation or off-gassing, resulting in nearly 100% oxygen utilization by the process.

Mazzei’s AirJection® Aeration System uses patented technology to provide the efficient transfer of oxygen into wastewater basins. The system features a low speed pump with corrosion resistant 316 stainless steel air injectors at the basin surface, and subsurface, non-fouling, basin mixing nozzles. The process aspirates air and provides small bubble mixing at the same time without the use of a blower. At the injector, air is mixed into a pressurized water stream at a velocity of 47 feet per second.
