Tank Cleanout Services

Tank cleanout services remove accumulated solids, sludge, and debris from equalization tanks, aeration basins, or clarifiers. Regular cleanouts are essential for maintaining capacity, preventing corrosion, and ensuring optimal process efficiency in wastewater plants.

Challenges:
Settled solids in tanks form compacted layers that are difficult to remove. These mixtures may include rags, sand, grease, and biological sludge — each posing different challenges to pump performance. Confined space entry, downtime, and equipment wear make manual cleaning costly and inefficient.

Solution:
Hevvy/Toyo submersible agitator pumps provide a safer, more efficient cleanout solution. The agitator breaks up settled sludge, allowing it to be pumped out completely without draining the tank. With recessed impeller designs, abrasion-resistant materials, and simple setup, Hevvy/Toyo pumps make tank cleanout faster, safer, and more cost-effective for municipalities and contractors alike.

Barge Unloading

Barge unloading in municipal wastewater operations typically involves transferring sludge, grit, or biosolids from transport barges to treatment or storage facilities. The process requires high-capacity pumping systems that can handle thick, abrasive, or viscous material efficiently.

Challenges:
Barge contents often settle during transport, creating dense, compacted sludge that’s difficult to mobilize. Standard pumps experience suction loss, clogging, and wear when handling high solids or abrasive material. Setup flexibility and mobility are also critical in temporary or remote unloading sites.

=Solution:
Hevvy/Toyo’s submersible dredge and slurry pumps excel in barge unloading. Their agitator systems re-suspend solids for complete barge evacuation, while wear-resistant materials withstand abrasive conditions. Compact and portable, they can be quickly deployed and moved between sites — providing reliable, high-throughput pumping for municipal sludge and solids transfer operations.

Digester Cleanout

Digesters are vital to wastewater treatment, converting organic waste into biogas and biosolids. Over time, dense grit, rags, and inert solids accumulate at the bottom, reducing capacity and efficiency. Periodic cleanouts are required to restore volume and performance.

Challenges:
Digester sludge is thick, corrosive, and often contains stringy or fibrous material that clogs conventional pumps. Cleaning operations are complex and must be completed quickly to minimize downtime. The combination of gas buildup, solids stratification, and confined-space conditions makes reliability and solids-handling ability critical.

Solution:
Hevvy/Toyo pumps provide safe and efficient digester cleanout with powerful agitation to break up settled sludge. Their robust wet-end design and open or recessed impellers pass fibrous material without clogging. Built with corrosion-resistant alloys and heavy-duty seals, they deliver dependable performance under the toughest anaerobic conditions — reducing labor and downtime.

Grit Chambers

Grit chambers are designed to remove sand, gravel, and other heavy inorganic particles from raw wastewater before it enters treatment processes. This step protects downstream equipment — such as pumps, clarifiers, and digesters — from abrasion and mechanical damage caused by suspended solids.

Challenges:
Grit is extremely abrasive and settles quickly, forming dense layers at the bottom of chambers and sumps. Standard pumps often suffer from rapid impeller wear, seal failure, and suction loss due to sediment accumulation. Periodic manual cleanouts are time-consuming, hazardous, and disruptive to operations.

Hevvy/Toyo Solution:
Hevvy/Toyo’s agitator-equipped submersible pumps are ideal for grit removal and chamber cleanouts. The agitator re-suspends settled solids, allowing complete sump evacuation without manual intervention. High-chrome or rubber-lined wet ends resist abrasion, while recessed impellers minimize wear — delivering long-lasting, low-maintenance performance in abrasive wastewater environments.
