Several forms of nitrogen occur in wastewater.
Each form is often analyzed to determine the total nitrogen content of both influent
and effluent samples in domestic and industrial wastewater's. These analysis assist waste
generators in their determination of treatment efficiency and allow for the determination
of impacts on receiving streams as effluent's are discharged.
The different forms of nitrogen and phosphorus are refereed to collectively as NUTRIENTS.
Nitrate (NO3), Nitrite (NO2), and Ammonia (NH4)
are considered inorganic forms of nitrogen and are analyzed separately in wastewater's
to determine the total inorganic nitrogen.
Total Kjehldahl nitrogen (TKN) is the combination of organically bound nitrogen and ammonia in wastewater. The organically bound nitrogen must be released from the organic matter by a process of digestion prior to analysis. This form of nitrogen is usually much higher on influent (untreated waste) samples then effluent samples. In most domestic wastewater facilities the biological activity breaks down the organic matter releasing and or consuming the nitrogen as energy in the process.
Total nitrogen is the combination of organic nitrogen and inorganic nitrogen (NH4, NO3, NO2).
Sample Submission
Due to workload and facility requirements all wastewater samples must have prior approval. All samples must be submitted in approved containers and delivered to the laboratory at 471 Williams Blvd. Richland, WA. Inquires about sample analysis not listed are welcomed and will be accommodated whenever possible.
