The client’s diffusers were severely clogged resulting in less than 40% of initial design flow. Two 500-HP blowers running full speed escalated electric bills and the facility was having trouble maintaining the minimum dissolved oxygen (DO) needed during the summer months jeopardizing compliance. Without any changes, the facility would be faced with significant costs to purchase nitrogen credits if unable to reduce the nitrogen loading below the target limit.
Inframark investigated different cleaning methods, including:
None of the options would have sufficed to either resolve the problem at a reasonable cost or within the required time, given the approaching summer months. Inframark creatively came up with a proposed recommendation to abandon the existing diffusers in place and install a new grid above them.
The new system would then allow the plant to meet demand with only one blower.
The client accepted Inframark’s recommendation, and the installation was completed in only one month (including one week with 8” of snow!)
The project added these benefits:
Most importantly, the facility could utilize a new aeration system through the summer months and meet process requirements.
Inframark separates itself from others by always looking for safe, compliant, and innovative solutions resulting in a customized and tailored approach for all its clients through Pure Alignment, Pure Accessibility, and Pure Accountability.
