Currently the US EPA has not promulgated a single method for the analysis of Total Nitrogen (TN). Most states that have TN regulations require permitee's to measure TN as the composite of TKN, Nitrate and Nitrite. This approach is costly, time consuming, and susceptible to variability based on the methods used for the individual analytes. We are excited to announce the introduction of a Total Nitrogen Test Method consisting of a single...  Continue Reading..

Construction and functional principle of a turbo blower of the current AERZEN AT and TB series are simple and at the same time effective. As the air supply of modern wastewater treatment plants is clearly designed for maximum availability, high energy efficiency and long maintenance cycles, AERZEN uses for the demanding bearing system within turbo blowers neither oil nor other lubricants - but simply air.  Continue Reading..

Mazzei’s GDT process delivers rapid and efficient ozone mass transfer under pressurized contacting conditions resulting in greater gas solubility.  Additional mixing and rapid gas bubble removal is provided by the system’s degas separator.  With high operational flexibility and low capital, installation and operating costs ― and all within a compact footprint ― the GDT mixing and contacting system is the best solution.  Continue Reading..

Best is the standard for quality at Sulzer’s manufacturing facility in Easley, South Carolina. Here, submersible pumps are modified and adjusted to meet specific needs of customers in the wastewater treatment industry around the USA.  Continue Reading..

Carlsen Systems in Woodbridge, Connecticut is a company with a mantra: “we never walk away from a problem.” The reliable performance of Sulzer products backed up by Sulzer’s expert support helps Carlsen to solve their customers’ challenges.  Continue Reading..

Mazzei’s wastewater basin aeration system thoroughly agitates bulk water and mixes ambient air or pure O2 into the wastewater.  Utilizing in-house CFD modeling, Mazzei systems are designed to ensure efficient mixing and aeration. Unlike blowers, Mazzei aeration is virtually silent, and requires little to no maintenance.  Continue Reading..

Mazzei’s lagoon aeration system is an efficient, low cost, quiet solution for wastewater problems. Optimally designed subsurface nozzles provide better mixing and agitating of wastewater than surface aerators.  Treatment efficiency increases as lagoon depth increases―no matter how deep―and the  system is easy to install and provides trouble-free operation.   Continue Reading..
