Sample Mailing Instructions
Typically, evaluations are completed in one to three business days. Please contact us prior to shipping samples if special circumstances exist or an expedited schedule is required.
Note: Polysaccharaide tests are ran one time per week so turnaround times may be longer.
- For activated sludge and most other systems, a 50 mL MLSS sample is needed. This should be collected from the end of the aeration process (generally the end of the aeration basin or feed to clarifier(s)) placed in a plastic, screw-capped bottle filled no more than ½ full (for air) with the lid taped.
- Overnight delivery is preferred.
- Please include an email address for the report to be sent to and billing information (name, phone number, and address of facility, email/person (s) to send invoice to)
If any foam is present on the aeration basin or final clarifier, this can be collected in a separate container (50 mLs is plenty) and analyzed at no additional charge.
If the system has multiple basins/trains each should be analyzed individually (do not mix into one sample). For lagoon systems, the effluent end of each cell is analyzed. Algae identification and counting is included in analysis. Lagoon samples should be collected in a well-mixed area (sample ports between each lagoon are ideal). 1000 mL is needed for each sample container because settling of sample is needed prior to evaluation.
