  • CS, MS, VI: Our basic platforms for automatic high-speed inspection of vials, ampules, cartridges, and syringes

    All three standard machines inspect up to 600 containers/minute, in addition to vials, ampules, cartridges, and syringes with liquid contents, as well as vials with lyo product. Depending on the inspection requirements, we can integrate any inspection technology of our Seidenader Solutions and add a machine module for leak testing.

  • CPI EDB offers the 3469 magnetron transmitter system for use as a high-power source of RF power for outdoor-mounted radar applications. The transmitter cabinet contains the high voltage power supply, solid-state switch, and the high voltage tank assembly which includes the pulse transformer, energy storage high voltage capacitor, and filament power supply.

  • UltraLite RF Cable Connectors are designed to perform at high frequencies and harsh environments with lower weight compared to their steel and brass counterparts by leveraging aluminum construction.

  • The Dual Seal Variable Volume Precision Dispense Pump is a robust, stepper motor-driven positive displacement pump designed for reliable dispensing of complex fluids, including those with high surfactant content or crystallization tendencies.

  • The Sensors Unlimited 640CSXCC+MMT is an ultra-compact Short-Wave Infrared (SWIR) camera designed for advanced imaging applications, including integration into Advanced Driver Assistance Systems (ADAS) and NVIDIA Jetson AI platforms.

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.
