PRODUCTS

  • NuGenesis LMS, the analytical electronic laboratory notebook capability of the NuGenesis Lab Management System (LMS), enables labs to document observations, control procedures, exchange information with other software solutions, and easily find and collaborate on scientific results. Additionally, it interacts with the NuGenesis SDMS (data archival) component, Waters Laboratory Acquisition Control Environment (LAC/E) devices, SAP, and Empower.

  • MS-S, VI-S: Our basic platforms for high-performance inspection of pre-filled syringes

    Our two standard machines for syringe inspection can be perfectly combined with our de-/renesters for Seidenader DE.SY.RE. Depending on the inspection requirement, we can integrate any inspection technology of our Seidenader Solutions.

  • The MMIQ-0416L is a low LO drive, passive GaAs MMIC IQ mixer.

  • SCIEX X500B QTOF System

    Engineered for standard biotherapeutic characterization analyses, the X500B QTOF system is a true benchtop instrument, with streamlined processing to get to a consistent, accurate view of your biologic. It is optimized for intact mass analysis, subunit analysis as well as high-quality peptide mapping workflows.

  • If you require oversight support of a capital equipment, facility, or utility project, Verista can act as your eyes and ears at the job site during installation, qualification and start-up. Verista can also be on site to represent your needs by monitoring the progress of your design firm, contractors, and equipment vendors if you have a corporate project at a remote location.

About Nutrient Removal

Nutrient removal from wastewater consists of treating wastewater to remove nitrogen and phosphorus before it reenters natural waterways. High levels of nitrogen and phosphorus in wastewater cause eutrophication, a process where excess nutrients stimulate excessive plant growth such as algal blooms and cyanobacteria. The decomposition of the algae by bacteria uses up the oxygen in the water causing other organisms to die. This creates more organic matter for the bacteria to decompose. In addition, some algal blooms can produce toxins that contaminate drinking water supplies.

As authorized by the Clean Water Act, the National Pollutant Discharge Elimination System (NPDES) permit program regulates point sources, such as municipal wastewater treatment plants, that discharge pollutants as effluent into the waters of the United States. In recent years, many of the States’ environmental bodies have lowered nutrient limits to arrest eutrophication. Maryland’s effort to protect the Chesapeake Bay and its tidal tributaries is perhaps the most notable example of nutrient removal in the US. Nutrient removal continues to be a growing area of focus for wastewater treatment throughout the world.   

The removal of nitrogen and phosphorus require different nutrient removal processes. To remove nitrogen, the nitrogen is oxidized from ammonia to become nitrate through a process called nitrification. This process is then followed by denitrification where the nitrate is reduced to nitrogen gas which is released to the atmosphere and removed from the wastewater.

Nitrification is a two-step aerobic process which typically takes place in aeration tanks. Denitrification requires anoxic conditions to encourage the appropriate biological conditions to form. The activated sludge process is often used to reduce nitrate to nitrogen gas in anoxic or denitrification tanks.

Phosphorus can be removed biologically using polyphosphate accumulating organisms (PAOs) which accumulate large quantities of phosphorus within their cells and separate it from treated water. Phosphorus removal can also be achieved by chemical removal. Once removed as sludge, phosphorus may be stored in a land fill. However, many municipalities and treatment facilities are looking to resell the biosolids for use in fertilizer.
