Accurate flow measurement ensures compliance with NPDES permit limits, which often specify allowable pollutant loads based on the volume of treated wastewater discharged.
Composite sampling combines multiple samples collected over a specified period (e.g., 24 hours), providing a better picture of fluctuating water quality conditions and pollutant loads.
A DO probe or meter measures the concentration of dissolved oxygen in water, which is critical for assessing the performance of biological treatment processes.
Grab sampling involves collecting a single sample at a specific time and location to analyze instantaneous water quality conditions, such as pH or dissolved oxygen.
TSS is measured by filtering a known volume of water, drying the residue on the filter, and weighing it. This quantifies the amount of suspended solids in the sample.
