What is the importance of BOD and COD in Wastewater treatment?
The significance of addressing wastewater parameters from the basic premise,allows us to comply with Government regulations. It has the potential to save us money, because better treatment means less downtime, less capital investment, avoiding fines and penalties, and, most importantly, less stress for us and the environment. Therefore, parameters such as BOD and COD are very important in wastewater treatment, to assess its quality.
Biochemical oxygen Demand (BOD)
The amount of dissolved oxygen (DO) used by aerobic microorganisms, when decomposing organic matter, is measured as BOD. Netsol's instruments can quickly measure BOD, to improve wastewater process control and plant efficiency.
Importance of BOD in wastewater treatment
The biochemical oxygen demand is an important water quality parameter, because it provides an index for determining the impact of discharged wastewater on the receiving environment.
Firstly, the higher the BOD value, the more organic matter or "food" is available to oxygen-consuming bacteria. Unfavorable conditions occur when the rate of DO consumption by bacteria, exceeds the supply of DO from aquatic plants, algae photosynthesis, or diffusing from the air.
Depletion of DO stresses aquatic organisms, rendering the environment unfit for life. Furthermore, severe depletion can result in hypoxia or anoxic conditions.
Secondly, BOD is also widely used in wastewater treatment, as the decomposition of organic waste by microorganisms is a common treatment method.In general, the maximum permissible amounts for direct environmental wastewater discharge are around 10 mg/L BOD.
Monitoring of BOD
It's no wonder that rapid BOD monitoring is becoming more popular, given that the alternative is a 5-7 day wait for lab findings.
Continuous organics monitoring opens the door to many new treatment process control, and optimization possibilities, which can result in significant cost savings, enhanced water quality, and peace of mind, about compliance.
Chemical Oxygen Demand (COD)
COD is a measurement of the amount of oxygen required in water, to oxidize soluble and particulate organic matter. With Netsol's COD instruments, COD can be measured quickly or in real-time, to improve wastewater process control and plant efficiency.
The significance of COD for wastewater treatment
Chemical Oxygen Demand is a significant water quality indicator because, like BOD, it provides an index for determining the impact of discharged wastewater on the receiving ecosystem.
Higher COD values indicate that there is more oxidizable organic material in the sample, which reduces dissolved oxygen (DO) levels, anda lower DO can result in anaerobic conditions, which are harmful to higher aquatic life forms.
Due toa shorter testing duration, the COD test is frequently used as an alternative to the BOD test.
Wastewater applications for BOD and COD measurement include
• Sewer Monitoring
• Chemical Dose Adjustment
• Aeration Enhancement
• Nutrient Dose Adjustment
• Management of Industrial Effluent Discharges
• Product Defects
• Advanced Treatment Monitoring & Security
• Improving Water Reuse
• Effluent Pollution Control
Wastewater parameters such as BOD, COD, TSS, turbidity, and others must be identified, so that the optimal treatment technique may be used.
We should all strive to lessen our overall environmental impact. This not only saves money for our businesses, but also addresses the wider picture: sustainability.
