Bergen County
In February of 2002, Bergen County started up a SAGTM system at their Little Ferry, NJ wastewater treatment plant to protect their generator engines and OCR catalyst from fouling. Bergen County had not been able to stay in compliance with NJDEP Air Emission Standards by utilizing their digester gas due to siloxane contamination. Following is a brief summary of this installation:
| Total Gas Flow: | 200 to 800 SCFM (turn-up/turn-down capability included in system design) |
| Siloxane Contaminants: | Siloxanes D4 and D5 |
| The Major Problem Area: | Siloxanes fouling engines, SCR catalyst (removed to below 0.3mg/m3) |
| System Configuration: | 3 SAGTM vessels in series |
| Annual Cost Savings: | $350,000 in natural gas costs alone plus lower maintenance on the engines and SCR catalyst from running cleaner digester gas |
Note: The Bergen County Utilities Authority was recognized for Innovative Air Pollution Control Technology for this project as a direct result of installing a SAGTM System. The press release follows:
| Fair Lawn, NJ, March 21, 2003 ? The Consulting Engineers Council of New Jersey (CECNJ), has recognized environmental firm Malcolm Pirnie, Inc. with a 2003 Engineering Excellence Award. Pirnie received an Honor award for its installation of an innovative biogas cleaning system at the Bergen County Utility Authority?s (BCUA) wastewater treatment plant in Little Ferry, NJ. The award was presented to Pirnie at an awards banquet in New Brunswick last evening. This project was also recognized as a finalist in the National American Council of Engineering Companies competition. |
