Shredding and reducing medical waste poses special challenges. Processing must meet stringent regulatory standards for the safe handling of infectious and red bag waste, including precise size reduction to ensure proper sterilization. In addition, the waste is comprised of many different materials, ranging from sharps to textiles, requiring shredders that can effectively process the variety of materials.
In addition to providing 15 minute chemical oxygen demand (COD) results and biochemical oxygen demand (BOD) estimates, the PeCOD® Analyzer measures natural organic matter (NOM) in fresh and treated drinking water. The PeCOD® Analyzer does what no other technology has done before. It quickly and safely measures oxygen demand and the associated oxidative changes in organic matter in fresh and treated drinking water, at low concentrations and without the use of hazardous chemicals. A new ASTM International...
Power plants are industrial facilities used to generate electric power with the help of one or more generators which convert different energy sources into electric power. Power plants need to monitor emissions continuously according to local emission regulations. Read about our solutions for the power industry!
Intrinsic kinetic tests involve adding relatively high concentrations of organic substrate to small concentration of acclimated microorganisms so that the COD/VSS ratio typically is greater than 10. Kinetic parameters are then determined by non-linear modeling using well-known relationships between biological growth and oxygen uptake.
PeCOD Analyzer Improves Pulp Mill Performance, Reduces Wastewater Pollution. MANTECH’s PeCOD technology is a safe and effective solution for improving wastewater treatment and optimizing the use of chemicals in pulp and paper mills.
MANTECH’s innovative PeCOD Analyzer is helping Ontario’s craft brewers manage their wastewater more effectively. PeCOD is an integral part of the Brü Clean System, a specialized wastewater treatment process developed by Econse Water Purification Systems for the craft brewing industry. Together they helped reduce the amount of wastewater for treatment by 75 per cent. “We can accomplish in a few minutes what other companies take weeks or months to do and this lets us move straight to effective...
Biodegradation tests involve testing samples in response to various parameters: dilution, nutrient addition, pH, temperature, and others. The pattern of oxygen uptake in aerobic tests; nitrogen gas production in anoxic denitrification tests; methane production in methanogenic tests; hydrogen production during glycolysis; and carbon dioxide production during fermentation reactions gives a measure of the rate and extent of biodegradation of the organic constituents of the test sample.
Coal power plant: Entrance of SCR denitration device, NOx O2
Exit of SCR denitration device: Measure remanet NH3 after reaction and avoid blocking by crystallization, NH3; Calculate denitrification rate with Nox input, NOx O2
Gas-fired power plant: Counting tail gas emission and realtime concentration, NOx O2 SO2 Temperature pressure flow dust
Pulse-Flow respirometers can be used to assess biomass activity for aerobic and anaerobic reactions. In aerobic tests, cultures are combined with nutrients, trace minerals, and an organic substrate – such as acetic acid or ethanol. The maximum oxygen uptake rate reflects the amount of active biomass in the test culture.
Toxicity of pure chemicals is assessed using respirometers by adding increasing concentrations to an active culture. The concentration at which oxygen uptake or gas production begins to decrease is known as the “threshold toxicant concentration.”
SO2 is one of several important pollutants in the atmosphere, SO2 from the atmosphere can stimulate people`s respiratory tract, abate respiratory function, and lead to respiratory resistance decreased, induce various inflammation of respiratory tract, harm to human health. SO2 also is harm to many plants. SO2 and its generated sulfuric acid mist can corrode metal surfaces and cause damage to paper products, textiles, leather products. It may also form acid rain, which is serious harm to the ecological system and...
PeCOD® is the only Chemical Oxygen Demand (COD) analysis technology to use the powerful UV-activated nanoparticle TiO2 (titanium dioxide) photocatalyst which is at the core of the system. The high electrochemical potential of the TiO2 gives it a substantial advantage over the modest chemical potential generated by the dichromate method. The UV light creates a photohole in the TiO2 sensor with a very high oxidizing power and organics in the cell are oxidized. PeCOD® is extremely accurate across a broader...
Modern production method of nitric acid production may lead to generation of several different gaseous emission components, such as nitrogen oxides (NOx), ammonia NH3 and nitrous oxide N2O. Nitrogen monoxide is an intermediate gaseous product in manufacturing of nitric acid HNO3. NO is formed in a catalytic reaction between ammonia and molecular oxygen O2. But undesirable side reactions may result in formation of nitrogen dioxide NO2 and nitrous oxide N2O. The NO and NO2 emissions can be reduced by use of Selective...
Most large coal fired power plants and combustion processes are required to monitor CO, NO and NO2 (NOx), SO2 and possibly CO2; in addition the analyser has to be normalised to Standard conditions. For this application CODEL offers the five channel GCEM 40 series which uses Infrared absorption to measure these gases plus moisture, pressure and temperature. The analyser can be configured for single channel operation to monitor any of these gases plus CH4 and HCl.
Cement is the main ingredient of concrete, which is the most common building material in the world. Cement industry is one of the biggest CO2 emission producers mainly due to the huge production capacities and calcination process, which is an important part of cement production. Cement manufacturers need to monitor these emissions continuously according to local emission regulations. Read about our solutions to the cement industry!
Safely storing liquids and chemicals is a continuous and ongoing effort in the Petrochemical Industry. Companies operating in this industry must deal with some of the unwanted effects that oxygen creates when present inside storage containers. Through a process called nitrogen blanketing, they inject this inert gas into the vapor space and effectively lower the concentration of oxygen. This in turns decreases the risk of fire, explosion, evaporation and structural corrosion.
The production of pure gases can be achieved through air separation. The process first involves cooling atmospheric air until it liquefies and then selectively distilling its components at their respective boiling points. An air separation plant will produce enormous volumes of high purity gases, typically nitrogen, oxygen, argon and sometimes other inert gases, and supply them to important industries. Different factories use different air separation techniques as part of their commercial production run. Cryogenic...
Marine monitoring is a variant of OPSIS general offers for continuous emissions monitoring (CEM) and process control. The special operating conditions on-board vessels call for special measures to comply with regulations and expectations. However, OPSIS has mastered this environment and has for many years successfully delivered systems for marine applications.
