Praxair has had an extensive history of innovation in the wastewater treatment process. About 15% of all wastewater treatment in the United States occurs in UNOX™ type systems. Since their original construction, many facilities now require adherence to new regulations. Praxair can help you make the required changes to ensure that your facility is running in the most efficient way possible and in line with current standards. We provide a wide range of technologies for UNOX™ facilities. These include enhancements that can help you achieve reduced operating costs and improved reliability through the upgrade of oxygen generation and dissolution equipment.
For the efficient, economical and reliable water treatment and wastewater purification you require high performance and reliable equipment for your plants.
Improved oxidation ditch mixing efficiency, lower energy use, and reduce maintenance with Envirex® Disc Aerators from Evoqua. Envirex disc aerators fit all existing single or multichannel oxidation ditch applications with little or no modification required.
Kaeser screw blowers use up to 35 percent less energy than conventional rotary blowers and even achieve significant energy savings compared to currently available screw blowers. The combination of a blower airend with high efficiency Sigma profile rotors, flow-optimized components, efficient power transmission and drive components ensures exceptional performance, guaranteed by Kaeser in accordance with the stringent requirements of ISO 1217.
Often times the biosolids management portion of the treatment plant may not be optimized, resulting in inefficient operation of the entire treatment plant. For instance, did you know that aerobic digestion is the second largest consumer of energy after biological treatment aeration at a wastewater treatment plant? Or, do you realize that up to 50% of the nutrient loading on any given day may be coming from the biosolids process?
The groundbreaking Delta Hybrid Rotary Lobe Compressor is the result of a synergy between the rotary lobe blower and the screw compressor technologies and offers completely new possibilities by combining the technical advantages of both concepts.
Mazzei MTM Mixing Nozzles provide dynamic mixing under pressure, which results in great mass transfer. When used in conjunction with the patented Mazzei® Injector, these nozzles dramatically enhance system mixing and contacting performance. Mazzei nozzles allow the delivery of treatment gases to any depth — all within a compact design, with trouble-free operation and easy installation. Many models are available for various applications.
Mainsail Global’s Boone diffuser membranes are designed for the petro-chemical market with hydrogenated acrylonitrile-butadiene rubber (HNBR). These custom membranes are built for durability, and can withstand long-term exposure to heat, oil and chemicals readily present in petro-chemical wastewater streams. With excellent tensile strength, abrasion and ozone resistance and higher modulus retention at elevated temperatures, Boone membranes combine the physical strength and chemical makeup of HNBR for an ideal solution in petro-chemical wastewater treatment.
