Tank and Lagoon Cleaning: why we now operate without draining

Cleaning industrial tanks and remediating industrial lagoons is essential to maintain efficiency and continuity of operations. Traditional methods require complete draining, which carries significant operational risks.

At Franchini Servizi Ecologici, we use non-draining cleaning techniques because this approach provides numerous advantages and reduces the risks associated with traditional methods:

• Prolonged plant downtime: stopping a tank or lagoon interrupts production or wastewater treatment cycles.
• High management costs: draining, transporting, and refilling significantly increases operational expenses.
• Safety risks: working in an empty tank exposes operators to more critical conditions, especially in confined spaces.
• Impact on efficiency: restarting the plant can take time and temporarily affect performance.

Thanks to modern technologies used by our company, it is possible to clean without draining, keeping the plant active and eliminating these issues.

What are Industrial Tanks and Lagoons

Industrial tanks and lagoons are key structures in production and wastewater treatment processes. They function as storage tanks, sedimentation systems, and flow regulation tools.

Their main functions include:

• Temporary storage of industrial liquids and wastewater
• Sedimentation of sludge, separating solids from liquids
• Biological or chemical treatment for water purification
• Regulation of flows within the plant

They tend to become dirty due to:

• Progressive accumulation of sludge and sediments
• Presence of industrial process residues
• Deposition of suspended solids

Risks if not cleaned:

Problem	Consequence
Accumulated sediments	Reduced storage capacity
Crusts and encrustations	Blockages and malfunctions
Stagnant sludge	Reduced purification efficiency
Odors and contamination	Environmental issues and fines

Without regular maintenance, these accumulations can severely compromise tank and lagoon efficiency.

Industrial Lagoon Remediation: when and why to intervene

Industrial lagoons are large basins where sludge and sediments accumulate over time. Remediation is essential to ensure process continuity and environmental safety.

Situations requiring intervention:

• Excessive sludge and sediment accumulation
• Reduced storage capacity
• Formation of crusts or layers difficult to remove
• Persistent odors or biological issues

Benefits of timely intervention:

• Prevention of more invasive extraordinary measures
• Maintaining plant operational continuity
• Reducing long-term management costs
• Preventing environmental risks and fines

Technologies for cleaning without draining

It is now possible to clean industrial tanks and lagoons without interrupting production thanks to innovative technologies. This approach ensures:

• Operational continuity: the plant remains active during cleaning
• Cost reduction: eliminates draining and refilling expenses
• Targeted interventions: works only where necessary, optimizing time and resources
• Increased safety: reduces operator exposure to hazardous conditions

The Franchini Servizi Ecologici team uses cutting-edge technologies to guarantee deep cleaning of industrial tanks and lagoons.

Professional / Tool	Function
Specialized divers	Mechanical sediment cleaning and targeted suction
Underwater ROVs	Robotic inspection and suction with video monitoring
Submersible pumps and suction devices	Controlled sludge transport to disposal systems

Divers and Underwater ROVs

The combined use of specialized divers and ROVs (remotely operated vehicles) allows intervention on tanks and lagoons without stopping the plant.

• They provide access to complex environments, even with difficult geometries and confined spaces
• They remove sediments selectively without disturbing the entire basin
• ROVs continuously monitor operations via integrated cameras and sensors
• Operator safety is increased, avoiding exposure to hazardous substances

Regulatory Compliance and Safety

Cleaning and remediation operations for industrial tanks and lagoons must strictly comply with environmental regulations and safety procedures.

It is essential to:

• Use qualified personnel and certified equipment
• Ensure traceability of removed sludge
• Follow specific protocols for confined spaces

Compliance protects the environment, reduces health risks for operators, avoids fines and legal liability, and ensures all operations are documented accurately, providing companies with certainty that maintenance is fully compliant and that plants remain efficient and safe.
