Restore Tank Capacity Without Draining Your Crew Into a Confined Space.

Grit, biosolids, rag, and scum build up faster than planned — quietly stealing volume from your digesters and clarifiers. ACS all-electric robotics break down and evacuate those solids while your team stays safely outside the tank.

A digester losing 25% of its working volume to grit is a plant running 25% over design load. ACS helps municipalities and industrial treatment operators recover that capacity — safely, on schedule, and with a full video record.

Why Treatment Operators Partner With ACS

Grit Steals Capacity

Studies have shown effective grit management can recover 12–25% of digester working volume. Manual cleanouts do it once every 10–15 years. ACS makes routine capacity recovery realistic.

Biogas & H₂S Hazards

Digesters are permit-required confined spaces with explosive methane atmospheres. Our tools hold hazardous-location ratings so the robots handle the hazardous work while your crew stays out of the tank.

Downtime = Treatment Risk

Every day a digester is offline, biosolids must go somewhere. ACS compresses cleanout timelines so parallel tanks don’t get overloaded.

Fixed Roofs, Few Entry Points

Anaerobic digesters and covered clarifiers don’t give you choices on mounting. Our quick-change mounting plates make manways, roof nozzles, and side ports all viable.

Rags & Plastics

Wipes, textiles, and microplastics accumulate and choke mixers and plug outlets. High-pressure Eliminator debulking cuts them down so they can be pumped out instead of entombed.

Extending Asset Life

Grit and rag chew through mixers, seals, and pumps. Removing built‑up solids reduces mechanical wear and helps protect high-value rotating equipment.

The Stack

Right-Sized Robotics for Every Plant

For a typical digester cleanout, the Eliminator breaks down compacted grit on the floor while the Orbiter washes mixing walls, internals, and cone surfaces. Both run from a single Overseer console.

Plant-Ready Control & Visibility.

Every ACS tool on site ties back to Overseer 3D (on a laptop) or Overseer Mobile (on a tablet or phone). Operators see a live digital twin of the tank, program cleaning patterns to match tank geometry and debris zones, and capture timestamped video for inspection and QA/QC records.

Digital twin view - visualize tank geometry and tool position as you clean.
Pattern control - set and adjust automated cleaning patterns from the console.set and adjust automated cleaning patterns from the console.
Live video - 21× optical zoom and lighting to watch the work as it happens.
Job record - store run data and video for internal reporting and future planning.
