Biochemical Oxygen Demand (BOD) 5 Day Application Note

by MANTECH INC.     based in Guelph, ONTARIO (CANADA)

The MANTECH PC-BOD is ideally suited for 5 day BOD analysis. Attached is an application note to illustrate the performance and trust for this important regulatory parameter.

Wastewater treatment for the textile industry

by Toro Equipment S.L.     based in La Cistérniga, SPAIN

A reduction in the Biochemical Oxygen Demand BOD5, produced in the bleaching, washing and dying processes for textiles.

Industrial wastewater treatment for industries

by MIOX Corporation     based in Albuquerque, NEW MEXICO (USA)

MIOX is the lowest cost supplier of chlorine for disinfection and oxidation of wastewater prior to discharge. Mixed Oxidant Solution (MOS) chemistry is more effective at biofilm control, Biochemical and Chemical oxygen demand removal (BOD/COD), breakpoint chlorination of ammonia and hydrogen sulfide (H2S) removal.

Wastewater solutions for the industrial effluent pollution management

by Real Tech Inc.     based in Whitby, ONTARIO (CANADA)

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 the frequency at which they can be measured for a given effluent.

TOC Correlation to BOD or COD

by GE Analytical Instruments     based in Boulder, COLORADO (USA)

Challenge: Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) are traditional parameters analyzed in the laboratory to determine organic matter in water and wastewater. Wastewater facility operators need to have constant data to monitor their discharges and optimize treatment processes (biological treatment, chemical dosing, etc). The requirements of BOD and COD analysis prevent them from being implemented as control parameters, however. The BOD five-day analysis time requirement does not allow an operator to use the data for process optimization and. although COD requires less time than the BOD, its analysis includes the use of hazardous chemicals and has no constant analysis capability.
