Digester & Tank Cleaning

Digester cleaning

Fergus Power Pump, Inc. has 30 years of accumulative experience in cleaning digesters and tanks. We provide cleaning services for digesters as well as all other tank structures.

Over time, digesters accumulate grit, trash and heavy solids that are not removed during normal wasting events.

This accumulation reduces the effective treatment capacity of the digester and negatively effects proper operation. Fergus Power Pump, Inc. can safely and efficiently remove and manage these solids.

Fergus Power Pump, Inc. can also remove heavy accumulations in oxidation ditches, aeration tanks, etc.
