Hayden, ID -- The Hayden Wastewater Research Facility (HWRF) is a full-scale research facility for Blue Water’s Blue PRO™ phosphorus removal process. In December, 2005 the process was set at steady-state conditions in order to determine the long-term stability of the process.
Two full-scale Blue PRO™ processes are being operated in series. Each pass uses a 50-ft2 filter. Flow through the first pass is 175 gpm with a 15 gpm recycled reject stream. The second pass is 160 gpm with 15 gpm recycled reject. HWRF receives secondary effluent from the Hayden Area Wastewater Treatment Plant.
Composite sampling was used to determine the average total phosphorus (TP) concentrations for the Blue PRO™ system each 24-hours. Samples were drawn from the influent to HWRF and the effluents from each pass. An independent laboratory is performing sample analysis. The laboratory uses EPA Method 365.3 for Total Phosphorus (TP), with a practical quantitation level (PQL) of 0.01 mg/L TP.
Up-to-date TP results are shown below. The process will be run at steady-state through March, 2006. After that regular research at HWRF will resume.
-Typical operating performance for one pass:
-TP lowered 90 - 98%
-Turbidity lowered 75 - 90%
-TSS lowered 85 – 95%
-BOD lowered as much as 80%
-Reagent dose of 8 - 15 mg/L Fe
