Water Treatment Tank Cleaners & Solutions

Bristola's Submersible Robotic Cleaning System (SRCS) removes sediment buildup using a remote-controlled robot that navigates the tank floor via sonar, vacuuming accumulated material through a flexible hose to an external processing point. The process works while the tank remains full and in service, requiring no draining, no manual labor inside the tank, and no operational downtime.

Bristola's patented zero-human-entry system removes sludge by deploying a submersible robot through the tank's existing manhole via the Equalization Chamber Entry System. The robot locates and extracts sludge deposits using sonar-guided navigation and flexible vacuum hose extraction. Tanks do not need to be emptied or taken offline — cleaning occurs while the facility operates at full capacity.

Yes. Bristola's technology is specifically designed to clean tanks, digesters, and covered lagoons while they remain in full production. The patented entry system allows the robot to enter and exit the tank through manholes as small as 24 inches in diameter without draining the tank or interrupting operations — a capability unique to Bristola worldwide.

Bristola's systems are compatible with anaerobic digesters, covered lagoons, water and wastewater treatment tanks, food and beverage processing tanks, pulp and paper facilities, oil and gas storage, steel mills, and agricultural waste management systems. Any tank with a manhole of 24 inches or greater in diameter can be fitted with the entry system via new build or retrofit.

The Patented Equalization Chamber Entry System acts as an airlock, allowing the submersible robot to pass through the tank's roof or cover via any existing manhole 24 inches or greater in diameter. This eliminates the need for human confined space entry entirely. The robot is remotely controlled from the surface and monitored with real-time sonar and performance data throughout the cleaning process.

A full Bristola service includes sludge removal, sonar-based sediment mapping, real-time monitoring, post-clean condition evaluation, and detailed data reporting on facility performance. Bristola also provides operator training, technical support, and ongoing maintenance through annual subscription plans. Feasibility studies are available for new or existing facilities evaluating waste management optimization.
