Digester Cleaning
Restore lost capacity and gas production with a contractor that has specialized in digesters for over 45 years.
We've always pushed agencies to clean digesters on a regular basis, not just when they're out of service or close to it. Grit, rags and settled solids steal active volume a little at a time, and regular cleaning keeps the process stable and the cost predictable.
USRS developed its own equipment and cleaning method to make digester cleaning as fast, safe and efficient as possible, which is how we typically come in at or below projected or budgeted costs.
USRS was instrumental in setting up some of the first long-term digester cleaning maintenance contracts with cities. Three- and five-year contracts keep digesters on a regular schedule and lock in lower pricing.
USRS is one of the longest-established digester cleaning companies in the country, and that history is why we're known as “The” Digester Cleaners.
Having this information ready speeds up your proposal. Our digester information form has always asked for:
Type (aerobic or anaerobic), gallons, diameter, sidewall and cone depth, year built and year last cleaned, mixing (hydraulic or gas), construction, lid type, sump.
Number and inside diameter of top manholes and side openings, outside ladder or steps, and any inside ladders and whether they're safe. Available lifting equipment.
Available amps from 3-phase 460/480 V service and a second breaker, water supply PSI and distance, pH, temperature, headworks and grit removal, blanket and bottom-sediment depth, dewatering target and haul distance.
