Wastewater treatment facilities that require reliable monitoring of dissolved oxygen (DO) for aeration, activated sludge, and nutrient removal control can optimize those processes with the new sc100 Controller from Hach.
Wastewater treatment facilities that require reliable monitoring of dissolved oxygen (DO) for aeration, activated sludge, and nutrient removal control can optimize those processes with the new sc100 Controller from Hach. With it, process managers can choose to use the company’s new LDO® Dissolved Oxygen (DO) Probe, which uses luminescent technology and eliminates the typical drawbacks of membrane components; a Hach membrane-methodology DO probe; or both, as conditions and requirements dictate.
Filtros has been issued a United States Patent for an all-ceramic gas diffuser for use in water and wastewater treatment. This one-piece design is formed of a gas permeable porous alumina diffuser ceramically bonded at high temperatures to an impervious ceramic holder yielding a corrosion resistant product. Stainless steel components, polymer gaskets and cements of any kind have been eliminated. Due to its leak free design, customers expect to experience lower operating costs by achieving higher efficiencies. Lower maintenance costs are also realized due to its gasket free design and one piece construction.

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. This combination increases transfer efficiency due to the entrainment in higher velocity loops created by the TFA.
The Envirex® Diamond edition membrane diffuser from USFilter, a Siemens Business, offers improved standard oxygen transfer efficiency (SOTE) values, higher maximum airflow limits per diffuser, lower diffuser headloss and longer diffuser life. Compared to other leading membrane diffusers, the custom-formulated EPDM material gives it a 50% greater tensile strength, which ultimately results in longer product life.

The Aqua-Lator® aerator, available from USFilter Aerator Products, is a high speed floating mechanical aerator. The aerator’s pumping action transfers oxygen by breaking up the wastewater into a spray of particles, creating more surface area for atmospheric pressure to drive oxygen into the wastewater. The aerators are widely used to treat wastewater at municipalities.

Submerged aeration system
Bio-Microbics recently introduced the Lixor submerged aeration system, a Venturi-type diffuser designed to provide aeration and mixing in a variety of wastewater applications. Low-cost pre-aeration, aeration, sweetening and mixing are just a few of the system’s potential uses. Individual or multiple units may be used in many ways as part of a wastewater plant design to help achieve desired treatment goals.

The Mazzei AirJection® aeration system provides high efficiency oxygen transfer in a small footprint design, with no depth limitations. The system comes with a certified Standard Oxygen Transfer Rate and documented Alpha values of 0.9 and higher. The process uses a recirculating pump and patented Mazzei® Injectors to dynamically introduce oxygen into the water system. It is then delivered to the bottom of the pond, tank or reservoir and discharged through Mass Transfer Multiplier Nozzles which increase oxygen transfer in the surrounding water.
