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.
Real Time Chemical Oxygen Demand Improves Wastewater Management. MANTECH’s PeCOD Analyzer water quality analysis technology provides food and beverage processors with accurate, real time data that enables them to make timely decisions and effectively manage their water and wastewater. The PeCOD Analyzer is a fast, green, accurate alternative to traditional chemical oxygen demand (COD) and biological oxygen demand (BOD) testing for measuring organics in wastewater. Rapid, reliable and economical testing...
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.
The production in the pulp and paper industry requires large amounts of water. The German Waste Water Ordinance implies that the resulting effluent has to be tested on the content of chemical oxygen demand (COD). In comparison with conventional testing methods the use of online COD analyzers offers high savings and also enables efficient water management.
Problem: A significant portion of the operational costs of a conventional municipal wastewater treatment plant employing an aerobic biological treatment unit comes from electricity costs associated with aeration. In many cases, the aeration rates are kept at the maximum level to ensure that the plant’s effluent is in compliance with the regulations. The critical parameter for regulatory purposes and treatment efficiency, BOD, takes 5 days to measure through standard methods providing almost no value to the...
Teledyne Tekmar has been the market leader in environmental and drinking water testing for decades, having invented many of the instrumental technologies used in today’s lab. From TOC drinking water analysis to EPA compendium methods for soil and water, Tekmar has the right instrument for your application.
MANTECH’s game-changing water quality analysis technology is revolutionizing wastewater treatment at industrial and municipal facilities worldwide. The PeCOD Analyzer provides accurate chemical oxygen demand (COD) results and biochemical oxygen demand (BOD) estimates within minutes rather than the hours or days required for standard COD and BOD testing — without the use of dichromate, mercury, acids and other harmful chemicals.
The U.S. Clean Water Act outlines hundreds of parameters for testing wastewater for discharge. It also gives an in-depth explanation of a wide variety of fines from several thousand dollars to over fifty million dollars. Keeping wastewater treated properly and within federal standards can save your organization money and time.
Problem: Industrial manufacturers face stringent regulations for discharging wastewater to the environment and municipal sewer systems. Biochemical Oxygen Demand (BOD) is a primary concern for many discharge limits, as wastewaters high in BOD can have adverse impacts on the aquatic environments by leading to oxygen depletion. In some cases, as a means to supplement BOD, it is also desirable to monitor chemical oxygen demand (COD) of industrial effluents. Both of these tests, are time and labour intensive reducing...
