Advanced Wastewater Treatment in Vancouver

A remotely operated submersible vehicle enters the tank through Bristola’s specialized entry system and travels to the tank floor using a winch arrangement. It removes sludge through a flexible hose to the facility’s chosen processing option. Operators manage the work from outside the asset, avoiding routine human entry while the tank can remain in service.

In many applications, Bristola’s system is designed to clean a tank while it remains in use. Unlike conventional methods that commonly require emptying the tank and stopping production, the robot removes sludge from within the liquid environment. Site conditions, tank configuration, sludge characteristics, and discharge handling should be reviewed before a cleaning plan is finalized.

Robotic cleaning is designed to reduce the need for personnel to enter a confined space during cleaning work. The remotely operated vehicle performs the in-tank sludge removal while operators remain outside. This can reduce exposure to confined-space hazards, but every facility should still follow its own safety procedures, hazard assessments, and applicable regulatory requirements.

The system can support wastewater and water treatment facilities, as well as industrial and commercial operations with liquid storage assets. It is applicable to tanks, anaerobic digesters, and certain covered lagoons. A facility assessment helps determine whether the asset’s access points, dimensions, contents, and operating conditions are suitable for installation and cleaning.

Sediment mapping uses sonar, GPS, and specialized software to create a detailed picture of a noncovered pond or lagoon. Reports can identify average and maximum water depths, sediment volume and thickness, plus settlement variations. Operators can use this information to monitor infilling rates, identify potential issues, and plan or budget for future dredging work.

Yes. Bristola can retrofit compatible existing storage facilities with the required portal, hardware, and system components. The tank is first manually cleaned to remove existing sediment and prepare it for installation. Once the system is installed, it creates a repeatable access method intended to support future cleaning without the same level of operational disruption.

A feasibility study investigates waste streams, takes material samples, reviews current system performance, and identifies areas for improvement. It can highlight both effective processes and operational challenges, then outline potential solutions and associated costs. This gives wastewater operators a factual basis for prioritizing maintenance, waste reduction, treatment changes, and capital planning decisions.

Provide available details about the asset, including tank or lagoon type, dimensions, access configuration, operating status, material handled, known sludge levels, and any previous cleaning history. Process constraints, site safety rules, and preferred sludge-processing options are also useful. This information helps determine system suitability and develop a practical scope for cleaning or retrofit work.
