The Three part assessment is fine.
Include more observations
Quantity of flow say
cbm per day or kl perday
Is it steady of there's sudden increase or low flow..
Whan the quantum of water is collected for process,
Pl assess and give the 1st tank as an equalisation tank equal to a day flow
Quality of flow means assessment of parameters
Physical
Chemical and
Micro bio logical
When cleaning up process is being assessed..
Each day flow data is needed
Process is done say for a few days..
Termed as
HRT ie Hydraulic Retention time
Data given in days.
NbSs ie Naturally Based Solutions if done.. 8 to 10 days given
If mechanised and more Chemicals added, it can be done within 4 to 5 days..
Can give more details as needed !

Wastewater monitoring, also known as wastewater surveillance or wastewater-based epidemiology, involves the analysis and monitoring of wastewater to gather information about the presence and levels of various substances and indicators. This approach has gained attention as a tool for assessing public health, environmental impact, and trends in community-wide drug use, infectious diseases, and other parameters. The following steps provide an overview of how wastewater monitoring works:
1. Sample Collection: Wastewater samples are collected from specific points in the sewer system or wastewater treatment plants. These sampling locations are strategically chosen to represent a specific population or geographic area, such as a city or neighborhood.
2. Composite Sampling: To obtain a representative sample, continuous or composite sampling methods are employed. Composite sampling involves collecting multiple discrete samples over a specific period, usually 24 hours, and then combining them to create a composite sample that represents an average concentration over that time.
3. Sample Preservation and Transport: Wastewater samples are preserved and transported to a laboratory under appropriate conditions to maintain sample integrity. Preservation methods may involve refrigeration, freezing, or the addition of chemical preservatives, depending on the target analytes.
4. Sample Preparation: In the laboratory, the composite wastewater sample is prepared for analysis. This may include filtration to remove debris, sediment, or coarse particles that could interfere with subsequent analytical techniques.
5. Analytical Techniques: Various analytical techniques are employed to measure and quantify specific substances or indicators of interest. These techniques can include chemical analysis, molecular biology methods (such as PCR), and advanced instrumentation like mass spectrometry or chromatography. The choice of technique depends on the target substances being monitored, such as drugs, pharmaceuticals, chemicals, pathogens, or specific biomarkers.
6. Data Analysis and Interpretation: Once the analytical measurements are obtained, data analysis and interpretation are carried out. This involves comparing the obtained concentrations or levels of specific substances with established baselines, reference values, or previous measurements. Statistical analysis and modeling may also be employed to estimate population-level trends or estimate the total amount of a substance discharged into the wastewater system.
7. Reporting and Communication: The results of wastewater monitoring are reported to relevant stakeholders, such as public health officials, environmental agencies, or researchers. The information can be used to inform decision-making, public health interventions, environmental management, or policy development.
Wastewater monitoring involves collecting sewage samples from different locations, analyzing them in laboratories for specific substances or pathogens, and interpreting the data to gain insights into public health, drug usage, or pollutant levels. This non-invasive method provides valuable, real-time information on community-wide health trends and environmental issues, aiding in informed decision-making by public health officials and policymakers.
Dear Alwielland Q. Bello et al.,
Aside from sampling and analysis there is also continuous (online) monitoring of flow rates and a range of quality parameters such as pH, temperature, turbidity, ORP, DO, EC, NH4/NH3, NOx, ...
