Industrial Cleaning Tanks

Bristola uses a patented equalization chamber — an airlock-type entry system installed on the tank's roof or cover. The remote-controlled submersible robot passes through this portal into the full tank, maneuvers using sonar navigation, and removes sludge through a flexible hose. The entire process requires no draining, no confined space entry, and no production downtime.

The Submersible Robotic Cleaning System is compatible with anaerobic digesters, covered lagoons, industrial liquid storage tanks, wastewater treatment facilities, food and beverage processing tanks, oil and gas refineries, pulp and paper facilities, and agricultural waste management systems. Any facility with a manhole 24 inches or greater in diameter is a candidate for this system.

Both. Bristola offers installation services for new builds as well as retrofits for existing facilities. The equalization chamber entry system can be adapted to fit any existing manhole 24 inches or greater, making it accessible for most operational facilities without requiring major structural modifications.

Bristola's systems are more cost-effective than traditional cleaning methods. A published case study demonstrates an annualized cost of $170,000 versus $250,000 for conventional methods — a savings of $80,000 per tank per year. Initial tank modification is approximately $150,000, with an annual subscription service also priced at $150,000. Exact pricing is available upon request.

Yes. Bristola provides an annual subscription cleaning service that includes full-service maintenance, real-time performance monitoring, data evaluation and reporting, and sediment mapping using advanced sonar technology. The subscription model ensures consistent upkeep while giving facility operators ongoing insight into tank condition and performance over time.

Bristola's zero-human-entry system eliminates the need to comply with confined space entry regulations under OSHA. It also reduces the carbon footprint of cleaning operations, supports renewable energy capture in biogas facilities, and maintains facility compliance during the cleaning process — all without interrupting ongoing production or requiring hazardous waste transport.
