Problem: The Medford (Wisconsin) Wastewater Treatment Plant had 1970s aeration blowers and was in changing to ammonia control. The blowers had a limited control range, leading to over-aeration and limited process controllability. The machines were not as efficient as the newer screw blowers.
Solution: The city worked with an engineering firm to design an optimized control solution using Kaeser high-efficiency FBS720L screw blowers.
Result: The plant’s process is optimized and is consuming nearly 50% less energy per month. 800-981-6888; www.us.kaeser.com
