Ontario는  폐수 처리 시설의 펌프 수명을 연장을 위해 새로운 고정자를 시행한다. 고정 시행의 궁극적인 이유는 더 적은 유지비용과 처리 운영의 초과시간으로 인한 고장시간을 줄이는 것이다.

도시의 폐수 처리시설 펌프는 거친 수질과 계속 견뎌왔다 그 결과 거친 폐기물은 펌프의 니트릴과 고정자의 짧은수명의 원인이 되고, 계속적인 유지와 고정자 교체 비용 문제가 발생했다.

Hamilton의 협력 단체는 Moyno는 새로운 우레탄 고정자를 도시 좁은 범위의 침전물 응용 시험을 했다. 그 시험은 hamilton의 예상을 뛰어 넘었다. 도시는 5개의 추가적인 우레탄 교체 고정자를 주문했다.

The city of Hamilton, Ontario has implemented new stators for its wastewater treatment plants (WWTP) as a means to increase pump life in the facilities, ultimately lowering maintenance costs and reducing downtime for its treatment operations over time.

The city of Hamiltons WWTPs have continuously battled with the abrasive quality of the processed water, and as a result, the abrasive sludge has caused shortened life for their nitrile stators. Further, it became an issue due to the cost of continuous maintenance and replacement stators.

Accordingly, Moyno partnered with Hamilton to test its new urethane stators in the citys abrasive municipal sludge application; their performance far exceeded Hamiltons expectations. As such, the city has ordered five additional new urethane replacement stators for its pumps after the first one outlasted the nitrile stator by more than 10 times and continued to operate without failure.

Hamiltons WWTPs collect both sanitary and combined sewage (wastewater). The collection system services not only the city but also the surrounding areas, including the towns of Dundas, Ancaster, Water Down, Glanbrook Township, and the former city of Stoney Creek.

The city of Hamiltons Woodward Avenue WWTP began operations in 1964 and today averages 409 million liters per day with a peak capacity of over 600 million liters per day. Likewise, the successful operation of its wastewater treatment is vital to the surrounding environment, especially the Hamilton Harbor.
