The AQUADISC 250 fine bubble air diffuser distributes the bubbles over the whole membrane surface to increase air/liquid transfer and to avoid coalescence. It is mostly used for aerating and oxygenating activated sludge tanks at municipal or industrial treatment plants.
Alternating Aerobic/Anaerobic Trickling Filter. Extended Aeration. Sequence Batch Reactor (SBR). Activated Sledge. High Quality Effluent (HQE) Single Use System. Rotating Biological Contactor (RBC).
Accurate monitoring of peak, low flow and total gas mass flow rates is a critical part of many industrial process control systems. If you need a portable analog or digital air flow meter that easily inserts into industrial ducts and pipes (up to 72 inches), choose Sierra Instruments Steel-Mass Model 640S.
The PURESTREAM, INC. package sewage treatment plant is an Extended Aeration treatment system. This treatment system works by providing ideal conditions for aerobic bacteria and other micro-organisms; these micro-organisms then decompose the biological contaminants in the raw sewage.
The Purestream Sigma low speed surface mechanical aerator is the result of years of development and refinement from hundreds of successful installations. The Sigma aerator offers the user unsurpassed durable construction, flexible design and maximum efficiency for wastewater treatment. These features make the Sigma Aerator the most cost-efficient ...
The Purestream, Inc. Package Rotating Biological Contactor System provides primary, secondary, and/or advanced treatment in one complete package. Package Plant sizes from 4200 to 112,000 GPD capacities.
The Sigma Lutin APM Series Submersible Mixer has a Stainless Steel propeller and shroud and is available in horsepowers ranging from 0.75 to 13.4. All sizes are available in 60 Hz., 230/460 Volt, 3 phase. The 0.75 Hp model is available in 110/230 volt, single phase as well.
Ammonium Measurement directly in the Medium – without Sample Preparation: The continuous measuring of O2 and NH4 can result in significant savings through: energy-optimized operation due to demand-oriented regulation of aerator aggregates, adherence to critical values or reduction of wastewater charges. The potassium measuring value can be ...
Jet Aerators transfer oxygen by simultaneously introducing large volumes of high kinetic energy liquid and air through a series of jet nozzles. The high velocity liquid exits the inner, primary jet and rapidly mixes with the incoming air in the outer jet. This intense mixing and high degree of turbulence in the gas/liquid cloud travels outward ...
Introduced in 1979 by Bayer AG, the Slot Injector is similar to a modern jet aerator but uses a slot-shaped configuration to achieve higher efficiencies. The slot-shaped nozzle and mixing chamber provide a greater shear surface for mass transfer than a circular jet opening of identical area.
