Filter Technology that kills Invasive Mussel Larvae

Protect your INDUSTRIAL WATER SYSTEMS FROM ZEBRA AND QUAGGA MUSSELS

Invasive mussels, such as zebra and quagga mussels, pose an increasing threat to industrial water systems. Their larvae are microscopic and can pass through conventional filtration systems undetected.

Once inside your system, they settle and grow, leading to blocked pipes and heat exchangers, higher maintenance and cleaning costs, and an increased risk of unplanned downtime. Once established, mussels are extremely difficult and costly to remove.

Challenges with
Invasive Mussels

RISK FOR YOUR PLANTS, PRODUCTION AND ECONOMIC EFFICIENCY

Uncontrollable
Spread

Distributed through ballast water tanks of large cargo ships, these larvae rapidly infest new ecosystems where they have few natural enemies.

Devastating Consequences
in Pipe Systems

Once a population establishes itself, thousands of tiny larvae are pumped into cooling water circuits. Withinjust 8 days, they grow to 200 μm in pipe systems, accumulating in and blocking your heat exchangers, spray nozzles, and entire pipelines.

High Risk of
Production Downtimes

As a result of blockages, your production equipment can no longer be cooled. This problem generally results in an inevitable shutdown of your plant in order to eliminate the risk of severe machine damage.

Enormous
Financial Damage

If left unprotected, your power plants, steel mills, and chemical companies will face annual damages of several million dollars, driven by costly production shutdowns and the expensive manpower needed for physical mussel removal.

OUR SOLUTION

Mechanical destruction of mussel larvae

With conventional systems, you retain mussels only to release them again during the backwash process, without eliminating the root cause.

With our solution based on hydrodynamic acceleration, you kill mussel larvae directly within the flow. Instead of filtering or retaining larvae, the system accelerates the fluid up to 12 m/s, directs the flow onto an impact surface, and mechanically destroys the microscopic mussel larvae.

You avoid the recirculation of living organisms, eliminate clogging, and minimize maintenance. Furthermore, the MUSSEL KILL system operates continuously (24/7) without moving parts and entirely without the use of chemicals.

REDUCE PRODUCTION RISKS AND ENSURE RELIABILITY

Protection: Safe operation of water intakes, cooling systems, and heat exchangers.
Cost Efficiency: Drastic reduction of maintenance costs and cleaning effort.
Preventive Care: Prevention of biofouling before it becomes a severe operational risk.
Increased Productivity: Enablement of continuous, reliable plant operation.
High Flexibility: Easy retrofit into existing setups (including competitor filtration systems).

Reduce production risks

Proof of Performance

Our system is designed and validated based on measurable engineering criteria
to ensure maximum operational reliability.

Measurable Impact

Targeting an 80–90% reduction of mussel larvae, the system actively helps preventcritical fouling in downstream equipment, reduces maintenance and cleaning intervals, and ensures stable operation.

Technical Approval

The underlying hydrodynamic principle and performance assumptions have been rigorously evaluated and approved by a German university.

Field Validation

To confirm this exceptional performance under real operating conditions, field validation (e.g., with the City of Zurich, Switzerland at Lake Zurich) is currently in preparation.
